Foreword
Georgia's Best Management Practices for Forestry
The purpose of this manual is to inform landowners, foresters, timber buyers, loggers, site preparation and reforestation contractors, and others involved with silvicultural operations about common-sense, economical and effective practices to minimize non-point source pollution (soil erosion and stream sedimentation) and thermal pollution. These minimum practices are called BEST MANAGEMENT PRACTICES and are commonly referred to as BMPs. They were initially developed in 1981 by a Forestry Non-Point Source Pollution Technical Task Force as required by the Federal Water Pollution Control Act. That act mandated states to develop a program to protect and improve the physical, chemical, and biological integrity of the nation's waters so they remain "fishable" and "swimmable" for today's and future generations.
Due to changes in technology and the rules and regulations governing land disturbing activities, the forestry community and regulators encouraged a revision of the 1981 BMPs. A separate set of wetland BMPs were developed in 1989 which were incorporated into the 1999 comprehensive manual by a similar task force. Between 1999 and 2009, additional guidance was developed, mainly concerning floodplain features, and those were incorporated into the 2009 manual by a similar task force. Since 2009, some additional clarifications and updates have been developed and incorporated into this latest 2019 version of the manual with guidance from a similar task force of stakeholders. This 2019 manual represents the collective best efforts to establish sound, responsible, guiding principles for silvicultural operations in the State of Georgia.

Section 1.0
Introduction

Georgia's 24.2 million acres of commercial forests provide a variety of benefits for the people of the state. In addition to forest products, forests provide clean water, clean air, soil conservation, wildlife habitat, flora and fauna, and opportunities for recreation, aesthetics, education, and research. These forests are managed by landowners with varying objectives and their individual management decisions may be designed to support a broad variety of specific focused benefits related to the list above and others from Section 7.0, page 56. Figure 1-A shows the percentage of forest land in the state and Figure 1-B indicates the ownership makeup of that forest land.

Georgia has 44,056 miles of perennial streams (approximately 4,000 miles of which are designated as mountain trout waters), 23,906 miles of intermittent streams and 603 miles of ditches and canals for a total of 68,565 stream miles. The state also has 425,382 acres of public lakes and reservoirs, 4.8 million acres of wetlands (nine percent tidally affected), 854 square miles of estuaries and 100 miles of coastline. This document emphasizes the protection of the state's water resources, when conducting forestry operations, through Best Management Practices (BMPs) in controlling or minimizing soil erosion and stream sedimentation. BMPs are the most appropriate or applicable practices to attain a silvicultural goal while protecting the physical, chemical, and biological integrity of the state's waters.

reviews, permits, fees, performance bonds

and compliance audits. See Section 8.3, page 65. Therefore, to prevent any

potential water quality problems, it is in the best interest of everyone involved

in silvicultural operations to properly plan and supervise their operations.

By consistently following BMPs, problems can be avoided or corrected as soon

as possible.

Since 1978, the Georgia Forestry Commission (GFC) has been designated

by the Georgia Environmental Protection Division (GAEPD) as the lead agency

to coordinate the forestry water quality program. The program's primary

responsibilities include: educating the forestry community on BMPs through

training and demonstrations; conducting BMP use and effectiveness monitoring

surveys; and investigating and mediating forestry water quality complaints.

Section 2.0
Planning for Water Quality
A ny forest management activity, regardless of potential impact on water quality, should be thoroughly planned. Whether the activity involves seasoned timber buyers or landowners selling timber for the first time, the planning process should address the objectives of the proposed activity as well as potential impacts of all actions that disturb the soil surface or impact water quality. The planning process should help identify sensitive areas and applicable BMPs to be used during timber sales, road construction, stream crossings, harvesting, site preparation, reforestation, and herbicide applications. The planning process should help identify terms and conditions of a written contract for any forestry practice. While BMPs do not specifically require written plans, it is generally a sound practice to maintain written records of any forest management activity on the land. Plans should include:
History of the site including past land use, Identification of sensitive areas such as perennial and intermittent streams,
ephemeral areas, lakes, ponds, wetlands, steep slopes, highly erosive or hydric soils, active gully systems, etc., Regulations and/or permitting requirements and location, type, timing and logistics of each activity.
Useful resources for planning forest operations include United States Geologic Survey (USGS) topographic maps, Natural Resource Conservation Service (NRCS) county soil survey maps with interpretations, aerial photographs and tax maps. These maps can help users locate tract boundaries and sensitive areas. Because no map is 100 percent accurate, they should be used as a reference to identify potentially sensitive areas that must then be verified and plotted during field reconnaissance to minimize impacts on them before silvicultural operations begin. GFC Offices can assist with finding soil maps, aerial maps, topographic maps, etc. The NRCS maintains soil and topographic maps at local field offices where field personnel can assist in map and resource information interpretation. These maps can be accessed by visiting www.websoilsurvey.nrcs.usda.gov.
Water quality protection begins with recognizing watercourses and water bodies. According to the federal Clean Water Act, "waters of the U.S." include lakes, rivers, perennial and intermittent streams, wetlands, sloughs or natural ponds. Georgia law (OCGA 12-7-3.13) defines "waters of the state" to mean all rivers, streams, creeks,
6

branches, lakes, reservoirs, ponds, drainage systems, springs, wells, and other bodies of surface or subsurface water, natural or artificial, lying within or forming part of the boundaries of the state that are not entirely confined and retained completely upon the property of a single individual, partnership or corporation.
Identifying stream types (perennial, intermittent, or ephemeral) is important in prescribing the level of protection through the implementation of BMPs listed in this manual. USGS topographic maps and NRCS county soil maps can be used as a reference to identify stream types. Where available, they should be cross-referenced and field verified. See Figure 2-A.

Section 2.0 Planning for Water Quality
Stream Types
Perennial streams flow in a well-defined channel throughout most of the year under normal climatic conditions. Some may dry up during drought periods or due to excessive upstream uses. They are usually identified as solid blue lines on USGS topographic maps and as either solid black or black lines separated by one dot on NRCS soil maps. Aquatic organisms are normally present and easily found in these streams.
Intermittent streams flow in a well-defined channel during wet seasons of the year but not for the entire year. They generally exhibit signs of water velocity sufficient to move soil material, litter and fine debris. They are usually identified as blue lines separated by three dots on USGS topographic maps and as black lines separated by two or more dots on NRCS soil maps. Aquatic organisms often are difficult to find or not present at all in these streams.
Ephemeral areas can direct stormflow into surface waters. Care should be taken to minimize these areas from becoming sources of pollutants. For a more detailed description and BMPs for ephemeral areas, see page 19.
The landowner or manager may be familiar with a stream's flow characteristics and make the determination of stream type. In some cases there may be uncertainty. For example, ephemeral areas may be difficult to locate when they are not actively flowing. In such situations, consult a qualified professional.
2.1 STREAMSIDE MANAGEMENT ZONES (SMZs)
Streamside Management Zones (SMZs) are buffer strips adjacent to perennial or intermittent streams or other bodies of water (lakes, ponds, reservoirs, etc.) that should be managed with special considerations to protect water quality. Trees and other vegetation in the SMZ provide shade that buffers water temperatures; woody debris vital to the aquatic ecosystem; natural filtration of sediment and other pollutants (nutrients and pesticides): and travel corridors and habitat for wildlife. SMZs also provide some flood protection by dissipating the velocity of moving water.
When planning and laying out harvest or treatment areas, SMZs should be identified on maps or aerial photos and clearly designated in the field with paint or flagging. You should also identify local, state or federal regulations that may supersede or mandate the use of BMPs, such as those for protected water-supply reservoirs/watersheds or protected river corridors.

2.1.1 Perennial and Intermittent Stream SMZ Width Recommendations
There is no uniform formula to determine the appropriate width of an SMZ. In general, however, the steeper the slope and more erosive the soil, the wider the SMZ should be. Slope should be determined at 100-feet perpendicular to the streambank. Therefore, SMZ widths may vary along a stream's course and on opposite sides of the same stream. SMZs should be measured along the ground from the streambank on each side of the stream and not from the centerline of the stream (Refer to Figure 2-B and Table 2-A).

Section 2.0 Planning for Water Quality
Remember that these are recommended minimum widths, and conditions such as unstable or erosive soils or lack of ground cover may warrant a wider SMZ for adequate water quality protection. SMZs also have a limited filtering capacity and are not intended to correct problems created by poor upslope or adjacent practices.
2.1.1.1 BMPs for Perennial and Intermittent Stream SMZs
(Does NOT include trout streams. Trout stream BMPs are discussed in 2.1.2) Management activities may occur within an SMZ provided that the disturbance to soil or ground cover is minimized. Water quality objectives should prevent movement of soil or other potential pollutants from within the SMZ into the watercourse and protect streambank integrity. The BMPs associated with typical silvicultural activities are listed below.
Identify any local, state, or federal regulations that may supersede or mandate the use of BMPs.
Determine and designate the appropriate SMZ widths on site prior to conducting any timber sale or forest practice.
Along perennial streams, leave an average of 50 square feet of basal area per acre evenly distributed throughout the zone or at least 50% canopy cover after a harvest to provide shade.
Along intermittent streams, leave an average of 25 square feet of basal area per acre evenly distributed throughout the zone or at least 25% canopy cover after a harvest to provide shade. Note that intermittent trout streams and intermittent trout stream tributaries will require a higher residual basal area as described further below (See Section 2.1.2.1, page 12).
Minimize stream crossings. (See Section 3.3 page 30 and 4.3 page 40) Except at planned stream crossings, locate new access roads outside the SMZ. Maintain existing roads within SMZs with adequate water control structures
and stabilization measures as needed. (See Section 3.2 page 27) If not possible, consider relocating road. Locate log decks, staging areas, and skid trails outside the SMZ, preferably on well-drained, stable soils. Where used, firebreaks should be installed parallel to streams and outside SMZs. (See Section 5.5 page 49)
10

Minimize the intensity of a prescribed fire in the SMZ to maintain forest floor cover and protect the soil surface.
Periodically inspect the SMZ and evaluate the effectiveness of the BMPs, adjusting practices when necessary.
In case of storm damage or forest health issues, refer to "Storm Damage and Forest Health Issues in Streamside Management Zones" found in the Appendix on page 67.
2.1.1.2 Practices to Avoid Within SMZs of Perennial and Intermittent Streams
Cutting streambank trees. Unnecessary access roads and main skid trails. Log decks. Portable sawmills. Significant soil compaction and rutting by harvesting equipment. Removal of ground cover or understory vegetation. Felling trees into the streambed or leaving logging debris in the stream. Servicing or refueling equipment. Mechanical site preparation and site preparation burning. Mechanical tree planting. Broadcast application of pesticides or fertilizers. Handling, mixing, or storing toxic or hazardous materials (fuels, lubricants,
solvents, pesticides, or fertilizers).
2.1.2 Trout Streams
Trout require cool (less than 70F), high-quality water. They, and the insects they eat, are extremely sensitive to sediment and thermal pollution (elevated water temperatures). Therefore, trout streams require additional protection. Streams designated as Primary Trout Waters are waters supporting a selfsustaining population of rainbow, brown or brook trout. Streams designated as Secondary Trout Streams are those in which trout can survive but there is no evidence of natural trout reproduction. The Georgia DNR Wildlife Resources Division publishes a list of Georgia's trout streams, available at www.georgiawildlife.com. For regulation purposes, the Georgia EPD maintains a list of trout streams at www.gaepd.org.
11

Section 2.0 Planning for Water Quality
2.1.2.1 SMZ Width Recommendation and BMPs for Trout Streams
Establish SMZs on both sides of designated trout streams and tributaries according to the following options:
Option A: For perennial trout streams and tributaries, a minimum 100-feet SMZ that includes a no-harvest zone within the first 25-feet of primary or secondary trout streams. Timber harvests within the remaining 75-feet of the SMZ should leave an average of 50 square ft of basal area per acre or at least 50% canopy cover. Option B: For perennial trout streams and tributaries within the 100-ft. SMZ, leave an average of 50 square feet of basal area per acre evenly distributed throughout the zone to provide shade. Option B may be selected if a qualified professional is consulted. Option C: Intermittent trout streams and intermittent trout stream tributaries should have a 35 foot or 50 foot wide SMZ, depending on valley slopes, according to the SMZ recommendations for slope on p. 9 of the BMP manual. (Note that the SMZ width of 20 feet corresponding to minimal stream valley slopes (0 to 20% slopes) is not recommended. In the event such minimal slopes are encountered in a trout stream watershed, use the 35 foot SMZ width.) Residual basal area requirements should be at least 50 sq. ft. of basal area per acre or higher within the SMZ for any trout stream or tributary within the SMZs of such trout streams or tributaries. The basal area should be evenly distributed within the SMZ to provide shade.
Follow all other BMPs for any type of trout steam noting the proper SMZ requirements.
2.1.2.2 Practices to Avoid Within SMZ of Trout Streams
Any forestry activity within 25 feet of the stream, unless using Option B or C. Mechanical site preparation and high intensity burns on ephemeral areas above
trout waters.
2.2 SPECIAL MANAGEMENT AREAS
Some water bodies in upland and bottomland areas have particular characteristics or regulatory requirements that require different management approaches. These include, but are not limited to canals and ditches, floodplain features, headwater areas, lakes and ponds, protected mountain tops, protected river corridors, sinkholes, water supply reservoirs/watersheds, and wetlands. In such situations, consult a qualified professional.
12

2.2.1 Canals and Ditches
Minor drainage to temporarily lower the water level on a wetland site during road construction, timber harvesting and site preparation is considered normal and exempt from 404 permitting. Most canals were established for flood control purposes prior to Section 404 guidance. Today, the construction of canals would most likely be considered major drainage and require Section 404 permits. Today, the construction of canals would most likely be considered major drainage and require Section 404 permits.
Construction of minor drainage ditches in wetlands is exempt from Section 404 permitting, provided: it does not result in the immediate or gradual conversion of a wetland to a
non-wetland; it does not facilitate the conversion from one wetland use to another; it does not significantly modify a stream, lake, swamp, bog, or any other
wetland or aquatic area constituting waters of the U.S.; it is not located in a SMZ.
2.2.1.1 BMPs for Canals and Ditches
Maintenance of existing canals and ditches (C&Ds) is allowed, provided the original dimensions are not exceeded. This is normally conducted at the end of each timber stand rotation.
In order to conduct maintenance dredging, access for equipment and the placement of spoil materials (sidecasting) is permitted along banks. Therefore, there may not be a tree canopy on one or both sides immediately adjacent to C&Ds.
Ditches constructed through non-wetland areas are not normally associated with natural stream channels. They dry out and water temperature violations should not be a problem. Therefore, no SMZ with basal area requirements is practical.
Where C&Ds were established in old perennial and intermittent stream channels that are now acting as the stream, the establishment of SMZs with basal area requirements is appropriate. Evaluate on a case by case basis.
Maintenance should occur during the dry season to prevent turbidity problems. If sediment is likely to move from C&Ds into a stream, consideration should be given to stabilization and sediment control
13

Section 2.0 Planning for Water Quality measures, such as sloping and grassing of ditch banks and spoil piles. The need for sediment control will be determined by soil type, the distance to a stream, and the amount of vegetated filter between the ditch and the stream.

(Modified from Mitsch and Gooselink, 1993 and Hodges, 1998.)
14

2.2.1.2 Practices to Avoid in Canals and Ditches
Bedding that channels surface runoff into C&Ds, including road ditches. Placing logging and site preparation debris in C&Ds. Excessive crossings; where necessary, fill over culverts should be stabilized. Applying chemicals that are not labeled for aquatic applications directly
to C&Ds with standing or flowing water.
2.2.2 Floodplain and Riparian Landforms
Floodplains support a wide variety of fluvial features, which perform diverse hydrologic, biological, and ecological functions. The objectives of this guidance are to better characterize floodplain features in terms of hydrology, geomorphology, and biology and also to provide better BMP guidance to protect water quality and biological integrity of these features.
The general goals of this guidance are to: Prevent movement of soil, fertilizer, and herbicide from forest operation areas
into the surface water system. Maintain water temperatures and dissolved oxygen levels adequate for biotic
survival. Maintain input of organic matter and coarse woody debris into water bodies. Maintain structural integrity of floodplain features.
Floodplain Features Overbank mainstem flows, mainstem backwater flow, floodplain groundwater drainage, and tributary inflows create many different features in floodplains (Figure 2-C). Such features include the main river channel, upland tributaries, springs and seeps, continuous side channels, braided streams, drainage channels, floodway, river bottom flats, discontinuous side channels, backwater paleo channels, backwater swamps, isolated depressions, oxbows/ponds, front bars, natural levees, and ridges. Although many of these features are broadly described as "sloughs," there is obviously great variation in their origin and form. The water quality effects of silvicultural activities along these features depend on the flood frequency and durations, flow regime or energy, and the types of forestry operations conducted. All of these factors should be considered when evaluating floodplain management. For example, if a discontinuous side channel is rarely
15

Section 2.0 Planning for Water Quality
connected to perennial streams, then it may serve as breeding habitat for amphibians, but is unlikely to serve as fish habitat. In this case, maintaining a stringer of bank trees to protect the stability of the feature and to provide some woody debris input is desired, but a larger streamside management zone (SMZ) for shade or for chemical adsorption and filtration is not necessary.
Determining all the relevant water body characteristics in a single site visit can be difficult. For guidance in determining the appropriate floodplain feature, see Figure 2-D. (The corresponding BMPs for each can be found in Table 2-B: Summary Characteristics of Floodplain Features and the Corresponding BMPs, on page 18.) These water types are: Tributaries that originate in uplands and flow across floodplain: These
usually well-defined channels with sandy substrate originate in the uplands and flow across the floodplain to the main river in continuous channel features. Springs and Seeps: Water emerges from these features within the floodplain and flows all or part of year in most years. Channel structure and substrate of springs are usually well defined and sandy, but those of seeps are less defined and mixed. If they flow all year long, treat them as perennial streams or otherwise as intermittent. Continuous side channels and Braided streams: These less distinct channels and banks flow intermittently and are connected to the main channel network at both ends. The channels often contain mixed substrates (sand, organics, fine sediments). Treat each channel individually, depending upon whether the stream is perennial, intermittent or ephemeral. These unique streams require highly site-specific management planning and recommendations. In some cases, the potential for wind throw of trees left in the SMZ will dictate variances in the removal of the canopy cover. Seek the assistance of a qualified professional. Drainage channels: These less distinct channels begin on the floodplain and usually flow intermittently during periods of high water tables via a continuous linear drainage system to the main river. The channels often contain mixed substrates (sand, organics, fine sediments). Floodway and River bottom flats: Area of floodplain with significant water velocities during frequent overbank flows (flows less than the two-year low flow). Evidence of scour and debris movement can be found. The floodway is usually identified on FEMA floodplain maps. Smaller floodway or riparian areas in minor streams are also called river bottom flats.

Discontinuous side channels: Channel features that may or may not be connected, on at least one end, to medium or higher flow energy channels. May have distinct or indistinct channel features, but the channel features disappear and reappear.
Backwater paleo channels: Usually well-defined deep channel features that are remnants of earlier river and side channel configurations. Mixed channel substrates (sand, organics, fine sediments). Flow usually backs into these features from the main river. Organic debris is often found piled against the "wrong" side of obstructions.
Backwater swamps. Backwater swamps are wetland areas formed in old overflow channels on the margins of floodplains at the base of the adjacent slopes. They feature wetland vegetation, hydric soils, and fine and organic substrates, but they may show evidence of scour and debris movement.
Isolated depressions: Feature wetland vegetation, hydric soils, fine and organic substrates, no evidence of fluvial scour.
Oxbows and Ponds: Ponded deep water (>2 feet deep), fine and organic substrates, no evidence of fluvial scour.
As a rule of thumb, if the following conditions exist, corresponding BMPs should be considered for all flooplain features. If the area has: perennial or intermittent water flows; establish SMZs. potential surface runoff inputs from adjacent lands (exception of flooding);
establish SMZs. steep, unstable, and/or well defined banks; protect banks by bank trees or
undisturbed zone. wet or ponded depression areas; shade water by bank trees. prolonged flooding areas; treat as a wetland and apply wetland BMPs. surface water; do not spray any chemicals.
Note: All flow regimes described above are based on normal flow conditions. Appropriate BMP adjustments should be required during excessively dry or wet conditions.
2.2.3 Headwater Areas
Headwaters include two types of conveyences: ephemeral areas and gullies. (Refer to Figure 2-E, Headwater Decision-Making Tree on page 20 to determine conveyance type. See Table 2-C: Headwater Stream Types and the Hydrological and Biological Characteristics, pg. 21.)

Section 2.0 Planning for Water Quality
Figure 2-E. Headwater Decision-Making Tree
2.2.3.1 Ephemeral Areas
Ephemeral areas are depressions or swales (sometimes called drains, draws, or dry washes) that have no defined continuous channel, and that are well-connected to intermittent or perennial streams. Ephemeral areas are characterized by water tables that often rise to the surface during high water table months, and these areas produce surface flow for short periods during and following rainfall. Forest floors in ephemeral areas are intact, and hydrophytic vegetation may or may not be present. Aquatic insects are usually not present in these areas. Soils in these areas may quickly become saturated during rainy or thawing periods. Soils in ephemeral areas feature finer textures and higher organic contents than soils in adjacent uplands. Fluvial power is generally low, but there may be evidence of small debris jams of leaf litter and other small organic matter deposited after surface flows. These areas are usually not identified on USGS or NRCS maps. Water from ephemeral areas may carry sediment and other contaminants directly into streams. Ephemeral Wetlands are a part of Ephemeral Areas, which exhibit partial or full wetland characteristics. 20

Silvicultural activities should: Minimize soil disturbance, litter layer removal, and avoid high-intensity
fire within ephemeral areas. These activities can increase the possibility of introducing pollutants to intermittent or perennial streams. Cover inadvertently exposed soils with logging debris, grass, or mulch. Minimize equipment trafficking within and around ephemeral areas. Should trafficking be justifiable due to site constraints, take precautions to minimize soil disturbance and litter layer removal. Placement of logging debris or logging mats in traffic areas may be appropriate. Debris, mats, and other soil protecting structures should not interfere with the natural flow of water. Avoid direct tie-in of turnouts and outfall of water bars/breaks to ephemeral areas. Extra care should be taken where a skid trail crosses an ephemeral area. See Section 5.3, page 48, for herbicide application. See Section 6.3, page 52, for fertilizer application.

Section 2.0 Planning for Water Quality
2.2.3.2 Gullies
Gullies are narrow ravines, often caused by past land cultivation. They are typically V- or U-shaped channels that may or may not have exposed soil surfaces within the channel. They carry water only during and immediately following rainstorms or thawing events. Dry wash, draw, swale, arroyo, and gulch are other common names for gullies. Old agricultural gullies often have mature trees growing within their banks. Gullies often occur in uplands, upper slopes of ephemeral areas, at relatively steep stream-sideslopes, or on exposed erodible soils. Gullies may or may not be directly connected to ephemeral areas, intermittent, or perennial streams. Because of their short hydroperiod, gullies do not generally provide suitable habitat for aquatic flora and fauna.
Gullies with a contributing area (catchment/watershed above the gully) larger than 0.2 acres and directly connected to ephemeral areas, intermittent or perennial streams may require special attention because they can be activated by forestry operations. For these types of gullies, the following BMPs are recommended, but soil, slope, and other topographic characteristics should be considered to address local conditions: Protect soil and litter layers within a gully and the banks during forestry
operations1. Low impact operational methods should be used for harvesting and site preparation in and around a gully. Placement of logging debris and slash in a gully is recommended to provide hydraulic resistance to flow and thus promote sediment deposition2. Avoid high-intensity prescribed burning in a gully to protect decomposed litter layers from burning and minimize exposure of mineral soils. Minimize trafficking within and around gullies, especially within and adjacent to severely eroded areas. Avoid direct tie-in of turnouts and outfall of water bars/breaks to gullies. See Section 5.3, page 48 for herbicide application. See Section 6.3, page 52 for fertilizer application. 1 Leaving some trees and shrubs on the banks and inside of gullies may serve as a marker
for subsequent harvesting, site preparation, planting, herbicide application, and other forestry operations. 2 Avoid creating an impoundment behind logging debris or slash placed in a gully.
22

2.2.4 Lakes, ponds, and other bodies of flowing water
Follow the BMPs recommended for perennial streams if they could potentially move sediments or other pollutants off site.
2.2.5 Protected Mountain Tops
Forestry activities on mountain tops above 2,200-ft. elevation with slopes greater than 25% including the reforestation requirement shall comply with BMPs. (See Appendix Section 8.2.3.4 with map, page 63.)
2.2.6 Protected River Corridors
Forestry activities within the 100-ft. buffers along those rivers at a point and below where the flow is 400 cubic feet per second (cfs) shall comply with BMPs. (See Appendix Section 8.2.3.3 with map, page 62.)
2.2.7 Sinkhole
A geologic feature, typically found in Karst geology, that might provide a direct connection between land surface and groundwater. Treat as perennial streams.
2.2.8 Water Supply Reservoir/Watershed
(See Appendix Section 8.2.3.1 with map, page 60.) For government-owned impoundments or intakes within a 100-square mile
or larger watershed, forestry activities within a 150-ft. buffer adjacent to all reservoirs and 100-ft. buffer adjacent to all perennial streams within a sevenmile radius above intakes shall comply with BMPs. For government-owned impoundments or intakes within a watershed of less than 100-square miles, forestry activities within a 150-ft. buffer adjacent to the reservoir, a 100-ft. buffer adjacent to perennial streams within a seven-mile radius, and a 50-ft. buffer adjacent to all perennial streams above the seven-mile radius shall comply with BMPs.
2.2.9 Wetlands
For regulatory purposes, wetlands are defined by the presence or absence of specific plant communities, hydric soils and hydrologic conditions. Because of the generally wet soil conditions associated with forested wetlands, these
23

Section 2.0 Planning for Water Quality
areas are sensitive to forestry activities. For instance, bottomland hardwood sites, Carolina bays, cypress domes, other swamps, and some pine savannas differ from upland forest types because their soils are wet most of the year. They frequently are connected directly to a larger aquatic system, often have overbank flow from nearby stream flooding, and may accumulate sediments and nutrients from upstream erosion and runoff.
To properly manage forested wetlands: plan for regeneration; consider the areas beyond the actual harvest site; and remember that special harvesting techniques may be necessary to protect water quality. Any stream channels should be identified and the appropriate SMZs established. The BMPs that apply to any other forest type generally apply to forested wetlands. For more information on harvesting and site-preparing wetlands, refer to Section 4.7 page 42 and Section 5.2 page 46.
Benefits of Planning
Forest managers, landowners, foresters, timber buyers, loggers, site preparation and reforestation contractors should clearly identify water bodies, Special Management Areas and streamside management zones (SMZs) in the field to decide which BMPs apply, when and where to apply them, and to carefully design access roads, log decks, and stream crossings. They should supervise these operations to make sure BMPs are followed where necessary, so that water quality is not compromised.
Forest health issues such as fire management, integrated pest management, disease control and natural disasters may also require a qualified professional to prescribe appropriate actions.
The benefits of a well written plan and/or written contract include: better communications of expectations between the landowner and forestry professionals; maximum return from the harvest; potential longer term productivity; better infrastructure; economic efficiency; minimal environmental impacts; compliance with federal, state and local laws; and avoidance of fines or penalties. For information regarding sample contracts and management planning, contact the Georgia Forestry Commission. Planning for the protection of water quality makes good sense.

Section 3.0
Road Location, Construction, Stream Crossings, Maintenance, Retirement
Access roads are an essential part of any forest management operation and provide access for other activities on forestland. With proper planning, location, construction, and maintenance techniques, wellconstructed access roads allow for productive operations and cause minimal soil and water quality impacts. However, poorly located, poorly constructed, or poorly maintained access roads, especially at stream crossings, can result in sediment-laden streams, changing stream-flow patterns, degraded fish and aquatic organism habitats, and adversely affected aesthetics.
There are two types of access roads typically constructed in the state. In mountainous and hilly terrain, the broad-based dip road is used. In the flatwoods and along major flood plains, the crown and ditch road is commonly used.
3.1 BMPs FOR ROAD LOCATION Identify federal, state and local laws, regulations or ordinances that apply to
road purpose, construction, and maintenance prior to construction and operation. Include needed considerations and measures to meet requirements. Use soil surveys and topographic maps to identify soils, stream locations and other natural features (rocky areas, steep slopes, wet areas, etc.) on the property that might pose problems. Locate potential control points, i.e. log decks and stream crossings on topographic maps prior to designing access roads in the field. New permanent access roads should follow the contour as much as possible with grades ideally kept below 10%. An engineer's divider can be used to lay out roads with the desired grade on a topographic map. Grades can run up to 12% for short distances. If soil is highly erosive, reduce grades. Plan to install water control structures. Temporary access roads should follow the contour as much as possible. Grades can run up to 25% for short distances provided that water control structures are properly installed. Except for planned stream crossings, locate new roads outside of SMZs. Minimize stream crossings. Where crossings are necessary, see Section 3.3, page 30. Minimize the number, length, and width of access roads. Locate new access roads on high ground, preferably on the sides of ridges, for proper surface drainage.
26

Locate new access roads on southern or western sides (aspect) of ridges if possible, to expose the roadbed to more sunlight.
Conduct site reconnaissance to verify road layout with potential soil problems, stream locations, sensitive areas (see Section 7.4, page 57), and watershed conditions.
Evaluate the condition of existing roads and potential water quality impacts. If necessary, plan for improvements or replace with new routes.
3.2 BMPs FOR ROAD CONSTRUCTION Construct access roads only wide enough (usually 12-16 feet) to safely handle
equipment that will use the road. Schedule construction during favorable weather. Maximize sunlight exposure along roadsides where surface drainage is
a problem. On permanent access roads with three percent or more grade, broad-based dips
should be installed at proper intervals; at 30-degree angles across road surfaces; have reverse grades of three percent; and the bottom of the dips should be outsloped about three percent. If necessary, outfall of dips may need sediment barriers such as rock, hay bales, or silt fence installed. (See Figure 3-A for a schematic of a broad-based dip road and Table 3-A, page 28 for recommended spacing of dips.) On temporary access or spur roads that have little traffic at low speeds, rolling dips can be installed. They resemble "stretched out" water bars. See Figure 3-B, page 28 and Table 3-A, page 28 for spacing. Figure 3-A: Recommended Spacing for Broad Based Dips in Permanent Access Roads and Rolling Dips in Temporary Access Roads

Keep roads free from obstructions and logging debris. Roadbeds on erosive soils should be stabilized with appropriate measures. Stabilize exposed soil on shoulders of permanent or temporary access roads
located within SMZs, wetlands or at stream crossings as soon as possible with any one or combination of the following: seed and mulch; silt fence; hay bales; excelsior blankets; geotextiles.
1. See Section 6.4, page 53 for grassing recommendations. 2. Type A (36 inch) or Type B (22 inch) silt fence can be used. Wooden
stakes should be fastened to the fence every six feet on the down slope side. The bottom edge of the fence should be installed in a four-inch deep trench with the bottom two inches of the fence facing upslope in the trench. See Figure 3-D. 3. Hay bales should be placed on sides in four-inch deep trenches and staked down. See Figure 3-E. Figure 3-D: Silt Fence Installation

Section 3.0 Road Location, Construction, Stream Crossings, Maintenance, Retirement
3.2.1 Practices to Avoid during Road Construction
Road construction inside the SMZ, except at planned stream crossings. Insloping of roads. Where unavoidable, use cross-drain culverts positioned under
the road at a 30 degree angle and spacing as in Table 3-B, page 28 for proper inside road drainage. Place riprap at culvert outfall to prevent washing. See Figure 3-F. Using ditches on steep roads. Some ditches may have to be lined with rock to prevent gullying and sedimentation. Turnouts tied directly into perennial and intermittent streams or ephemeral areas.

3.3 STREAM CROSSINGS FOR ROADS
Stream crossings are often necessary for access to forestlands. From a water quality standpoint, stream crossings are the most critical aspect of the road system. Failure of a stream crossing, due to improper planning or construction, can result in erosion and introduction of sediment into a stream, adversely affecting water quality.
Where crossings are necessary, planning should address the type of road and road-use pattern, stream channel characteristics, stream flow levels and the aquatic organisms in the stream. Minimizing impacts is critical. Permanent and
30

temporary stream crossings should be based on expected applicable storm-flow return intervals and watershed acreage above the crossing. See Table 3-C, page 34.
3.3.1 Clean Water Act Provisions and Requirements for Stream Crossings
The Federal Clean Water Act, Section 404, (40 CFR Part 232.3), exempts normal, established, ongoing silvicultural activities from the permitting process for discharges of dredged or fill material in jurisdictional wetlands. However, fifteen (15) baseline provisions for forest road construction and maintenance in and across waters of the U.S. (lakes, rivers, perennial and intermittent streams, wetlands, sloughs and natural ponds) are mandated to qualify for the forest road exemption:
1. Permanent roads, temporary access roads and skid trails (all for forestry) in waters of the U.S. shall be held to the minimum feasible number, width and total length consistent with the purpose of specific silvicultural operations, and local topographic and climatic conditions;
2. All roads, temporary or permanent, shall be located sufficiently far from streams or other water bodies (except for portions of such roads that must cross water bodies) to minimize discharges of dredged or fill material into waters of the U.S.;
3. The road fill shall be bridged, culverted or otherwise designed to prevent the restriction of expected flood flows;
4. The fill shall be properly stabilized and maintained during and following construction to prevent erosion;
5. Discharges of dredged or fill material into waters of the U.S. to construct a road fill shall be made in a manner that minimizes the encroachment of trucks, tractors, bulldozers or other heavy equipment within waters of the U.S. (including adjacent wetlands) that lie outside the lateral boundaries of the fill itself;
6. In designing, constructing and maintaining roads, vegetative disturbances in the waters of the U.S. shall be kept to a minimum;
7. The design, construction and maintenance of the road crossing shall not disrupt the migration or other movement of those species of aquatic life inhabiting the water body;
8. Borrow material shall be taken from upland sources wherever feasible; 9. The discharges shall not take or jeopardize the continued existence of a
threatened or endangered species as defined under the Endangered Species
31

Section 3.0 Road Location, Construction, Stream Crossings, Maintenance, Retirement
Act, or adversely modify or destroy the critical habitat of such species; 10. Discharges into breeding and nesting areas for waterfowl, spawning and
wetlands shall be avoided if less harmful alternatives exist; 11. The discharge shall not be located in the proximity of a public water supply
intake; 12. The discharge shall not occur in areas of concentrated shellfish production; 13. The discharge shall not occur in a component of the National Wild and
Scenic River System; 14. The discharge of material shall consist of suitable material free from toxic
pollutants in toxic amounts; and, 15. All temporary fills shall be removed in their entirety and the area restored
to its original elevation.
Note: The ultimate determination of whether activities are exempt can only be made by the US Army Corps of Engineers and the US Environmental Protection Agency.
There are three types of stream crossings to consider in forest management operations: bridges, culverts, and fords.
Bridges, whether permanent or temporary, typically create the least disruption to stream flow and have less effect on fisheries than other streamcrossing methods.
Culverts can be either temporary or permanent. Culvert sizing is critical to minimizing problems. Consider both the purpose of the crossing and the duration of use. Sizing may increase if the need is permanent.
Fords can be used for haul roads only where the streambed is firm, banks are low and stable and the stream is shallow.
3.3.2 General BMPs For Stream Crossings
In addition to the 15 CWA mandated provisions Approaches to all permanent or temporary stream crossings should be
made at gentle grades of slope (three percent or less) wherever possible. Approaches should be made at right angles to stream flow where practical. Approaches should have water control structures, such as water turnouts or
broad-based dips, on both sides of a crossing to prevent road runoff from entering the stream. 32

If necessary, approaches should be stabilized with rock extending at least 50 feet from both sides of the streambank during the operation.
For temporary access roads, temporary bridges or spans are favored over culverts or fords.
Wetlands fill roads should be built outside the SMZ, except when crossing the channel. Cross-drainage structures (culverts, bridges, portable spans, etc.) may be necessary in the fill road to allow for surface water movement across the site.
Exposed soil around permanent or temporary stream and wetlands crossings should be stabilized with any one or a combination of the following: seed and mulch; hay bales; rock; silt fence; geotextiles; and/or excelsior blankets. (See Section 3.2, page 27)
3.3.3 Specific BMPs for Bridges Use bridges to cross streams with 300 + acre or larger watersheds if other
alternatives are not suitable for containing storm flows. Remove temporary bridges and stabilize approaches and streambanks
when operations are completed.
3.3.4 Specific BMPs for Fords Use fords only for haul roads (not skid trails). Locate fords where stream banks are low and the bottoms are relatively
hard and level. Where necessary, establish a smooth, hard-surface, low water crossing. For a
permanent ford use gravel or rock filled geowebb, or concrete pads. For temporary fords use dragline mats or logs to armor (protect) the stream bottom. Material should not significantly impound stream flow, impede fish passage or cause erosive currents. Remove temporary crossings from the channel when operations are completed.
3.3.5 Specific BMPs for Culverts
Where fords or bridges are not appropriate, use culverts to cross streams with approximate 300-acre or less watersheds, depending on physiographic region, including braided streams in broad flats. See the figure on the inside cover of this manual.
33

Section 3.0 Road Location, Construction, Stream Crossings, Maintenance, Retirement

When crossing streams with a watershed larger than 300 acres, consult a qualified professional.
Size permanent culverts so that the cross-sectional area will accommodate expected 25-year, 24-hour storm flows. See Table 3-C for recommended diameters.
Size temporary culverts so that the cross sectional area will accommodate the two-year, 24-hour storm flows. See Table 3-C for recommended diameters. Under normal conditions, two alternative methods are acceptable:

See Figure 3-G. Culverts less than 15 inches in diameter are not recommended.

34

Figure 3-G: Combination of Smaller Culvert and Rock Surfaced Road Dip
Multiple culverts should be spaced a distance of at least 1/2 the culvert's diameter apart.
Place the culvert in a straight section of the stream, free of obstructions. Place the bottom of the culvert at the same elevation as the bottom of the
stream. (See Figure 3-H, page 35, for proper culvert installation.) Place fill dirt around the lower half of the culvert and pack during installation. Figure 3-H: Stream Culvert Installation with Specifics of Slope, Placement, Fill, etc.

35

Section 3.0 Road Location, Construction, Stream Crossings, Maintenance, Retirement
Place at least 15 inches or at least 1/3 the culvert's diameter, whichever is greater, of fill dirt over the top of the culvert so that the fill over the culvert is the high spot in the stream crossing. This creates an emergency runaround for high flows.
The culvert's ends should be long enough to achieve no more than a 1:2 slope on the fill.
Stabilize fill at ends of a culvert with riprap, geoweb, excelsior blankets, gabions, headwalls, grass seed and mulch, hay bales, etc.
Periodically inspect culverts and remove any debris inside. Remove all temporary culverts and fill material used in stream or wetland
crossings and stabilize streambanks when operations are completed. (See Section 3.2 for stabilization recommendations.)
3.3.6 Practices To Avoid When Constructing Stream Crossings Using steep approaches greater than three percent into the stream channel. Crossings at bends in the stream. Using fords in streams for skid trails. Constructing hard surface crossings on streams with mucky, muddy or
unstable bottoms. Using asphalt materials for low-water crossings. Anything that impedes the free or expected flow of water. Temporary crossings of logs and brush "topped" with soil. Using undersized culverts.
3.4 BMPs FOR THE MAINTENANCE AND RETIREMENT OF ROADS Maintain existing roads in accordance with BMPs.
Maintain points of ingress from county roads or highways to prevent the introduction of mud and debris onto these roads.
Minimize road grading and reshaping on hilly or mountainous terrain unless required to repair damaged road sections.
Keep outfall of broad-based dips, water bars, and water turnouts open at all times during logging operations. If necessary, install sediment barriers such as rock, hay bales, or silt fence just below outfall.
Retire temporary access roads, log decks, skid trails, by re-shaping and/or constructing water bars at recommended intervals. Stabilize as necessary by
36

seeding and mulching or scattering logging debris over the road surface. (See Figure 3-I and Table 3-D for spacing recommendations.) Periodically inspect retired roads to assure stabilization techniques are still effective and permanent stream crossings are clear and operating properly.

Section 4.0
Timber Harvesting
Timber harvesting encompasses several operations. In addition to cutting trees, it typically includes the layout of access roads, log decks, and skid trails and the construction and stabilization of these areas. Timber harvesting can be accomplished while protecting water quality and site productivity and improving the composition and quality of future forests. Evolving timber harvesting technology, equipment, and procedures will provide for better protection of Georgia's waters.
Potential water quality impacts can be avoided or minimized if the harvest plan addresses seasonal weather conditions, stand composition, soil type, soil moisture, topography, and type of equipment used. In order to maintain the integrity of stream banks, water flow, and stream biology, it is important to stay out of streams. Specific BMPs for log decks and skid trails are provided in this section. BMPs for roads are presented in Section 3.
4.1 LOG DECKS
Log decks, also called brows and landings, are areas of concentrated equipment and traffic resulting in a high degree of soil disturbance, soil compaction, and rutting. Storm water runoff and surface erosion may increase on these exposed areas and, depending on their locations, could impact water quality. Runoff may contain toxic materials from fuels and lubricants. The following BMPs should be implemented to prevent runoff from reaching nearby watercourses.
4.1.1 BMPs for Log Decks
Locate log decks when planning the road system. Minimize the number of log decks necessary for the operation. Minimize the size of log decks to minimize the affected area. Locate log decks uphill and skid up to them. This results in a cone-shaped
pattern of skid trails, which disperses water running downhill. If trees must be skidded downhill, erosion can be minimized using smaller log decks with fewer, shorter and less-traveled skid trails leading to any one deck. To disperse water, install water bars with water turnouts in skid trails prior to final approach to deck. Locate log decks in a stable, well-drained area away from gullies when possible. When the harvest is completed, stabilize as needed, using water bars, logging slash or vegetative cover. (See Section 6.4 for seeding recommendations.)
38

Control and minimize site-damaging effects to soil stability and water quality, such as rutting, puddling and compaction from harvest equipment.
4.1.2 Practices to Avoid for Log Decks
Locating log deck within the SMZ. Allowing decks to concentrate storm runoff onto roads, trails, etc. leading
to a watercourse.

4.2 SKID TRAILS
Skid trails are for temporary use during the timber harvest. You should strive to control and minimize site-damaging effects to soil stability and water quality, such as rutting, puddling, and compaction from harvest equipment. If trails will remain after the harvest for vehicular access, upgrade them to road building standards.

4.2.1 BMPs for Skid Trails
Skid uphill to log decks on ridges or hills. Have periodic breaks in grade to
help disperse surface flow. Use temporary closure techniques,
such as water bars or covering with logging slash, if significant erosion may occur before permanent closure techniques are installed. Retire, as needed, as soon as possible with properly installed water control structures. For water bars see Figure 3-I, page 37, and Table 4-A for proper spacing. When grades exceed 15%, use water bars with water turnouts.

*Sensitive areas might include SMZ edge, drains (gullies/ embankments/canals/ditches), F.B. Intersections, roads, and cover change (a change between forestland and openland). ** Use grades of 40% and steeper only for short stretches.

4.2.2 Practices to Avoid With Skid Trails
Trails over 40% grade except for short stretches. Bladed trails unless required on side slopes to create the appropriate
grade for safe operations. Using stream and drains with defined channels as skid trails. Main skid trails within SMZs.

39

Section 4.0 Timber Harvesting

4.3 SKID TRAIL STREAM CROSSING
In certain situations, crossing a stream with a temporary skid trail may be preferable to a permanent road crossing. Factors to consider include the value of the timber to be accessed relative to the cost of a permanent crossing, topographic features limiting construction of permanent crossings, and the size of the stream and/or the upstream watershed. Regardless of the factors, the considerations for protecting water quality are critical to maintain the integrity of the stream bank, to use water-permeable fill materials that are easy to recover in the restoration process, and to minimize the amount of fill dirt entering the stream.

4.3.1 BMPs For Skid Trail Stream Crossings
Follow Federal mandates. (See Section 3.3.1, page 31) Minimize the number of crossings. Cross stream at right angles. Maintain stream bank integrity. Approach streams at gentle grades of slope, ideally at less than three percent. Use of temporary bridges or spans is preferred rather than temporary culverts. If temporary culverts are used, make sure they are properly sized for the
watershed. (See Table 3-C, page 34.) Stabilize culvert fill during and after construction using any one or a combi-
nation of: hay bales; seed and mulch; silt fence; rock; excelsior blankets; geotextiles; etc. (See Section 3.2, page 27) Use logs or stems as fill over temporary culverts instead of fill dirt whenever possible. Remove all temporary fills and restore the channel to its original elevation. Stabilize approaches during and after construction. When using a bridge for a skidder crossing, the span should be fully covered to avoid depositing soil/debris in the channel.

4.3.2 Practices to Avoid For Skid Trail Stream Crossings
Stream crossings whenever possible. Use of fords. Blocking stream flow. Blocking the migration of aquatic
organisms. Using sloughs as skid trails. 40

Portable steel bridge

Random crossings with mechanized equipment. Leaving logs or stems in stream crossing.
4.4 RUTTING
During harvesting, some soil disturbance and rutting is inevitable, due to the mechanized nature of most harvesting systems. Excessive or inappropriate rutting can impact water quality when it causes sediment or silt-laden runoff to enter a stream or when it interrupts or changes the natural flow of water to the stream. Rutting that results in the discharge of sediment to a stream may violate federal and state water-quality laws.
4.4.1 BMPs to Minimize Rutting
Use low ground pressure equipment, logging mats, or other techniques on saturated soils where practical.
Minimize the grade of skid trails. Follow the BMPs recommended for skid trails in Section 4.2, page 39.
4.4.2 Practices to Avoid For Rutting
Facilitating the potential movement of sediment to a stream or water body. Breaking down the integrity of a stream bank.
4.5 EQUIPMENT WASHING AND SERVICING
Improper equipment washing and servicing can introduce hazardous or toxic materials to the harvest site, which can affect water quality.
4.5.1 BMPs for Washing and Servicing Equipment
Wash and service equipment away from any area that may create a water

quality hazard, especially within SMZs and along ephemeral areas. Dispose of oils, lubrications, their containers and other wastes according to
local, state and federal regulations. Remove all used tires, batteries, oil cans, and trash from logging
operations before leaving the site. Clean up and/or contain fuel and oil spills immediately. Comply with
state and federal regulations when reporting spills. Report any fuel, oil or chemical spills to the DNR EPD Hazardous Substance Office at 1-800-241-4113.
4.5.2 Practices to Avoid When Washing and Servicing Equipment
Washing or servicing equipment where it could affect water quality.
4.6 PROTECTING STREAMSIDE MANAGEMENT ZONES (SMZs) DURING HARVESTING
4.6.1 BMPs for Harvesting Streamside Management Zones
In addition to the BMPs listed in Section 2.1, page 8: Use techniques that minimize soil disturbance, such as backing trees out
with machine using low ground pressure equipment, using equipment with booms, or cable winch. Maintain the integrity of stream banks. Minimize the exposure of mineral soil by spreading logging slash and using it to drive over.
4.6.2 Practices to Avoid When Harvesting Within SMZs
In addition to the avoidance guidelines listed in Section 2.1, page 8: Using trees or de-limbing gates in the SMZ. Leaving tops in stream channels. Rutting.
4.7 PROTECTING WETLANDS DURING TIMBER HARVESTING
4.7.1 BMPs FOR HARVESTING FORESTED WETLANDS
In addition to the recommendations in Section 2.2.9, page 23:

Plan the timber harvest for the dry season of the year when possible. Use site-specific equipment and methods to minimize water quality im-
pacts, including high-flotation, low-pressure harvesting equipment, shovel logging or cable yarding. Concentrate skid trails and use logging slash, mats or other techniques to minimize soil compaction and rutting. Use practices conducive to rapid regeneration. Follow federally mandated stream and wetland crossings. (See Section 3.3.1, page 31.)
4.8 MAT (SHOVEL) LOGGING
Minimize the width of skid trail mats. Mats should not exceed an average 20 feet in width, except for sections of the trail where it is necessary for equipment to pass; in these sections the minimum width may be doubled.
Minimize the number of skid trail mats. Typically, trails should not be spaced closer than 200 feet, on average. Where conditions prohibit tracked machines from operating off the mat and to minimize site disturbance, spacing may be reduced to 50 feet. However, under no conditions should skid trail mats exceed 25% of the harvest area.
Timber for skid trail mats should be laid down in the direction of the trail under normal conditions.
Use only one layer of timber for skid trail mats, except where multiple layers are necessary to prevent site disturbance.
Where multiple layers of timber are necessary to construct the skid trail mat and to maximize weight distribution, the bottom layer may be laid down perpendicular to the trail, and may exceed 20 feet in width.
Merchantable material in skid trail mats should be removed after logging operation is complete.
For stream crossings with skid trail mats, refer to the stream crossing section of the BMP Manual.

Section 5.0
Site Preparation and Reforestation
Site preparation facilitates the regeneration process and is the first step toward successful regeneration. Typical methods prepare harvested and non-forested areas for desired tree species and stocking. Site preparation may be used for both natural and artificial forest regeneration. Methods chosen should reduce logging debris, lessen logging impacts, control competing vegetation, and enhance seedling survival.
The site preparation technique used depends on soils, slope, condition of the site, vegetation, crop tree species, cost, location and landowner goals. Analyze the erosion potential of the site prior to any site preparation. Topography, soil type and residual ground cover determine erosion potential.
Topography The steepness and length of the slope are major considerations when determining the treatment intensity. Intensive treatments that are acceptable in areas of little or no slope may be unacceptable in areas of steep slope.
Soil Type Soil types or mapping units differ in texture, slope, stoniness, erodibility, wetness or other characteristics that affect the use of the soils by man. Soil surveys describe these limitations as slight, moderate, or severe. Any limitations should receive extra attention in order to prevent soil degradation.
Residual Ground Cover The amount, species and size of ground vegetation, logging debris and other organic matter should be a consideration in prescribing the type and intensity of the treatment.
Site preparation techniques can be grouped into three categories: mechanical, chemical, and controlled burning. Combinations of these techniques are common.
5.1 MECHANICAL SITE PREPARATION
Mechanical site preparation includes shearing, raking, subsoiling, chopping, windrowing, piling, bedding and other physical methods to cut, break apart or move logging debris, or to improve soil conditions following harvest. This category is often described by its impact on the soil. Methods vary from low intensity to high intensity. High-intensity methods such as disking and bedding expose the soil on more than 50% of the site. Chopping is a low-intensity method. Erosion potential usually increases with higher-intensity methods, especially in areas with steep slope. Therefore, high-intensity methods are appropriate for flat and gentle slopes, used with caution on moderate slopes, and avoided on steep
44

slopes. Low-intensity methods are preferred on moderate to steep slopes.
5.1.1 BMPs FOR MECHANICAL SITE PREPARATION
Thoroughly plan the site preparation before beginning the job to ensure that the best treatment is implemented.
Use the minimum intensity of site preparation required. On slopes of 6%-10%, intensive mechanical methods should follow the
contour of the land. On slopes of 11%-20%, mechanical methods other than chopping should
follow the contours of the land. On soils with moderate to severe erosion potential, strips of untreated areas or windrows should be left to slow water and soil movement down the slope. On slopes of 21%-30% with severely erosive soils, use only low-intensity mechanical methods that follow the contour. Drum chopping should be perpendicular to the slope. On slopes greater than 30%, use only hand tools (chain saw felling). Where accelerated erosion is likely, use methods that leave logging debris and other litter scattered evenly over the site. When constructing beds on slopes greater than five percent, follow land contours. Protect forest floor and limit soil disturbance in stabilized gullies that are not eroding.
5.1.2 Practices to Avoid During Mechanical Site Preparation Any mechanical methods except drum roller chopping or spot cultivation on
slopes greater than 30%. Drum chopping should not follow the contour. Intensive mechanical methods on slopes greater than 20% with severe
erosion potential. Windrow construction that could direct runoff into waterways. Mechanically preparing sites when soils are saturated. Mechanical methods in SMZs. Blocking any drainage with beds, windrows, or similar structures. Bedding that channels surface runoff into waterways and roadbeds. Moving soil into windrows and piles. Re-activating stabilized gullies.

Section 5.0 Site Preparation and Reforestation
5.2 MECHANICAL SITE PREPARATION IN WETLANDS
Forested wetlands offer unique challenges for site preparation. The EPA and Army Corps of Engineers have determined that major drainage in jurisdictional wetlands will require a Section 404 permit from the Army Corps of Engineers. Also a 404 permit may be required for mechanical site preparation for pine establishment in the following forested wetland types, unless they no longer exhibit their unique distinguishing characteristics due to past practices: 1. Permanently flooded, intermittently exposed and semi-permanently
flooded wetlands: Examples include Cypress-Gum Swamps, Muck and Peat Swamps, and Cypress Strands/Domes. 2. Riverine Bottomland Hardwood wetlands: Seasonally flooded or wetter bottomland hardwood sites within the first or second bottoms where overbank flooding has resulted in alluvial features such as natural levees. Soils are listed in NRCS surveys as poorly or very poorly drained. Bottomland hardwoods do not include sites in which greater than 25% of the canopy is pine. 3. White Cedar Swamps: Wetlands greater than one acre in headwaters and greater than five acres elsewhere, underlain by peat of greater than 40 inches, where natural white cedar represents more than 50 % of the basal area and where the total basal area for all tree species is 60 square feet or greater. 4. Carolina Bay wetlands: Oriented, elliptical depressions with a sand rim, either underlain by (a) clay-based soils and vegetated by cypress or (b) peat of greater than 20 inches and typically vegetated with an overstory of Red, Sweet, and Loblolly Bays. 5. Non-riverine Forest wetlands: Rare, high quality (undisturbed) wet forests, with mature vegetation, located on the Southeastern coastal plain, whose hydrology is dominated by high water tables. Two forest community types fall into this group: Wet Hardwood Forests -- interstream flats comprising ten or more contiguous acres typically found on the margins of large peatland areas that are seasonally flooded or saturated by high water tables. Soils are listed as poorly drained mineral soils. Vegetation is dominated (greater than 50% of basal area) by mature swamp chestnut oak, cherrybark oak, or laurel oak, alone or in combination. Swamp Forests -- flats comprising five or more contiguous acres found on sites that are seasonally to frequently flooded or saturated by high water
46

tables. Soils are listed as very poorly drained. Vegetation is dominated by mature bald cypress, pond cypress, swamp tupelo, water tupelo, or Atlantic white cedar, alone or in combination.
Note: Sites dominated by red maple, sweetgum, or loblolly pine alone or in combination are not considered to be of high quality, and therefore do not require a permit. 6. Low Pocossin wetlands: Central, deepest parts of domed peatlands on
poorly drained interstream flats, underlain by peat soils greater than 40 inches, typically vegetated by a dense layer of short shrubs. 7. Wet Marl Forest: Hardwood forest wetlands underlain with poorly drained marl-derived, high pH soils. 8. Tidal Freshwater Marshes: Wetlands with dense herbaceous vegetation located on the margins of estuaries or drowned rivers and creeks regularly or irregularly flooded by freshwater. 9. Maritime Grasslands, Shrub Swamps, and Swamp Forests: Barrier island wetlands in dune swales and flats, underlain by wet mucky or sandy soils vegetated by wetland herbs, shrubs, and trees.
These forested wetland areas are more precisely described in an EPA and Corps November 1995 memorandum concerning Application of Best Management Practices to Mechanical Silvicultural Site Preparation Activities for the Establishment of Pine Plantations in the Southeast. Consult a qualified professional for additional information to determine if one of these wetland types is on a site.
5.2.1 Other Wetlands
Other jurisdictional forested wetlands do not require a Section 404 permit if conducted according to the following six federally mandated minimum BMPs.
5.2.1.1 Federally Mandated BMPs for Mechanical Site Preparation in Wetlands
1. Position shear blades or rakes at or near the soil surface. Windrow, pile and move logs and logging debris by methods that reduce dragging or pushing through the soil to minimize soil disturbance associated with shearing, raking and moving trees, stumps, brush and other unwanted vegetation.
2. Activities should avoid excessive soil compaction and maintain soil tilth.
47

Section 5.0 Site Preparation and Reforestation
3. Arrange windrows to limit erosion, overland flow and runoff. 4. Prevent disposal or storage of logs or logging debris in SMZs. 5. Maintain the site's natural contour and ensure that activities do not
immediately or gradually convert the wetland to a non-wetland. 6. Conduct activities with appropriate water management mechanisms to
minimize off-site water quality impacts.
5.3 CHEMICAL SITE PREPARATION
Herbicides are a valuable tool in forest management and are used to control competing vegetation in the establishment and management of natural and planted pine stands. If conducted properly, herbicide treatments are acceptable site preparation methods on all slopes.
Proper planning and execution are key to safe herbicide use. Follow label directions and applicable state and federal laws in the storage, transportation, handling and application of all herbicides. Apply restricted-use herbicides only under the supervision of a certified pesticide applicator.
5.3.1 BMPs For Chemical Applications
Establish appropriate buffers along perennial and intermittent streams and flowing bodies of water.
Consider weather conditions such as temperature, wind speed and precipitation, equipment capabilities and pesticide formulations to avoid pesticide drift into the SMZ.
Conduct all on-site pesticide handling, such as tank mixing, loading and rinsing equipment, away from streams, ponds, wells and roadside ditches.
Dispose of pesticide containers and/or excess pesticides according to label requirements and local, state and federal regulations.
Clean up and/or contain all pesticide spills immediately and comply with local, state and federal regulations for reporting hazardous materials spills. Report spills to the DNR EPD Hazardous Substance Office (1-800-241-4113).
5.3.2 Practices to Avoid During Chemical Applications
Applying a pesticide directly to water bodies (streams, lakes, and swamps), unless it is specifically prescribed and labeled for aquatic management.
Broadcast applications of pesticides within SMZs.
48

5.4 SITE PREPARATION (CONTROLLED) BURNING
Controlled fire is often used alone or in conjunction with chemical or mechanical site preparation to prepare sites for regeneration. A properly executed site prep burn only slightly increases the chance for erosion. Fires that expose significant mineral soil on steep slopes, however, may increase erosion potential. Other factors also must be taken into consideration. If in doubt about appropriate site preparation treatment, consult a qualified professional.
5.4.1 BMPs for Site Preparation Burning
Unless protected by natural barriers, the area to be burned should be protected by firebreaks installed following BMP recommendations. (See Section 5.5)
Moisture levels within the soil, forest fuels and the air should be sufficient to prevent major exposure or damage to the mineral soil, especially on moderate to severely erosive soils.
Exclude high-intensity site preparation fires from the SMZ. Cool, low-intensity, hazard-reduction fires that do not consume the duff layer are allowed.
5.5 PRE-SUPPRESSION FIREBREAKS
Pre-suppression firebreaks aid in site preparation (controlled) burning, prescribed burning and in controlling wildfires. Proper planning and BMP implementation for pre-suppression firebreaks can minimize sediment delivery to surface water. Aerial photographs, topographic maps, or county soil survey maps should be used to locate tract boundaries, streams, wetlands, rock outcrops, gullies, cemeteries, etc. that require extra precautions.
5.5.1 BMPs for Firebreaks
Best Management Practices (BMPs) should be followed when installing firebreaks. BMPs are methods used to prevent or reduce soil erosion and water pollution as required by the federal Clean Water Act. Under the provisions of this Act, landowners can be subjected to fines of amounts up to $50,000 per day for water quality violations that occur on their property.
General procedures for pre-suppression firebreaks: 1. Plan location of firebreaks - Aerial photographs, soil maps and
topographic maps combined with an on-site evaluation will help identify
49

Section 5.0 Site Preparation and Reforestation

the streams, gullies and highly erodible sites on the property. Proper

planning will ensure that firebreaks are effective and environmentally sound.

2. Use natural barriers such as roads, streams, and fields as firebreaks

where possible.

3. Identify Streamside Management Zones (SMZs) - SMZs are designated

areas adjacent to streams or other bodies of water that require special

management to protect water quality. They are determined based on

steepness of the slope and whether the stream flow is intermittent or perennial.

SMZ width may range from 20-100 feet (see Chart 2-A). Wider SMZs may be

required for protected water supply reservoirs.

a. Exclude firebreaks and intensive fire from SMZs when possible.

b. If firebreaks must be connected to a stream, construct them by using hand

tools or by back-blading with a dozer in the SMZ.

c. Install proper water diversions where firebreak crosses SMZ boundaries.

4. As much as possible, install firebreaks on the contour rather than along

property lines, and when firebreaks cannot be installed on the contour,

use a gradual grade.

5. Firebreaks installed with a flat blade or disc-harrow are preferred.

These breaks erode less than plowed breaks.

6. To avoid channeling water between firebreaks and sensitive areas,

install appropriate water diversions in firebreaks according to BMP

recommendations (see Table 5-A) - A water diversion moves water away

from the main firebreak and into a stable area. It is usually constructed with

an angled berm of varying height

Table 5-A. Spacing of Water Diversions

that is suitable to redirect water flow

across the full width of the firebreak.

This angled berm is connected to an

angled opening or turnout that will

allow water to drain away from the

break into a stable, vegetated area.

Note: Drains = gullies/ephemerals/canals/

ditches

7. Firebreaks and appropriate water

*Sensitive areas might include SMZ edge, drains (gullies/ ephemerals/canals/ditches), Firebreak intersections, roads, and

diversions installed parallel to

cover change (a change between forestland and openland). Some examples of openland might include fields, utility right-of-ways,

roads, drains, and other firebreaks parking areas, driveways, yards, etc. ** Use grades of 40% and steeper only for short stretches.

50

should be at least 10 feet away from the edge. 8. Whenever roads, drains, cover changes (a change between forestland
and openland) and/or firebreaks are crossed or tied into, install appropriate water diversions about 10 feet from the intersection. Use low impact methods such as backblading, handlines, or water lines to tie into roads and drains whenever possible. 9. Treat active gullies the same as streams, using appropriate buffers and plowing practices. 10. Treat ponds the same as perennial streams, maintaining the same SMZ based on slope.

Best Management Practices take a small amount of extra time, but result in firebreaks that will serve you and the environment well.

5.5.2 Practices to Avoid During Firebreak Construction
Firebreaks that channel surface runoff into streams, roads, or gullies. Plowing inside the SMZ.

5.6 REFORESTATION
Reforestation can be accomplished artificially or naturally. Natural regeneration and hand planting generally pose less of a threat to water quality than mechanical methods. Complete artificial regeneration projects as quickly as practical. A qualified professional can provide advice on reforestation choices.

5.6.1 BMPs for Reforestation
Hand plant on >21% slopes with severely erosive soils.
Machine plant on the contour on slopes between 2% and 20%.

5.6.2 Practices to Avoid During Mechanical Reforestation
Machine planting up and down slopes greater than five percent.
Machine planting within SMZs.

Section 6.0
Management and Protection
6.1 PRESCRIBED BURNING/HAZARD REDUCTION
Prescribed burning is used to reduce hazardous accumulations of forest fuels, manage competing plant vegetation, improve wildlife habitat and perpetuate certain endangered plant and animal ecosystems. When properly planned and conducted, prescribed burning has minimal impacts on water quality. These burns should follow federal, state, county and local regulations.
6.1.1 BMPs for Prescribed Burning Follow same BMPs as in 5.4 and 5.5 page 49.
6.2 WILDFIRE SUPPRESSION
Wildfires are suppressed aggressively with the safety of personnel and equipment a primary concern. After suppression, when safety allows, BMPs should be installed during mop up or as soon as possible.
6.2.1 BMPs for Wildfire Suppression Firebreaks Locate camps and staging areas on upland sites. Stabilize areas designated for water supply points and dip sites for helicopters
to prevent excessive rutting from support equipment. Mix and/or handle fire retardants, lubricants, etc. away from streams,
ponds, wells and roadside ditches. Repair wildfire suppression firebreaks as soon as practical after the fire is
under control to meet BMPs for pre-suppression plowing.
6.3 FERTILIZATION
Forest fertilization is a valuable silvicultural practice that enhances tree survival and growth. The primary nutrients applied are nitrogen and phosphorus. Plan any forest fertilization to prevent direct applications and runoff into water bodies. When conducted properly, forest fertilization poses little threat to water quality. Fertilizer applications should not result in the exceeding of state water quality standards for nitrates and phosphorous for lakes. For more information, contact the DNR EPD Water Protection Branch for those standards.
6.3.1 BMPs for Fertilization Consider weather conditions (such as temperature, wind speed and precipi-
52

tation) and equipment capabilities to avoid fertilizer drift into the SMZ. Conduct all on-site fertilizer handling, such as mixing and loading, away
from streams, ponds, wells and roadside ditches. Clean up and/or contain all fertilizer spills immediately and comply with
any local, state and federal regulations for reporting spills of hazardous materials. Dispose of fertilizer containers and/or excess fertilizer according to local, state and federal regulations and label requirements. In case of accidental spills, call the DNR EPD Hazardous Substance Office at 1-800-241-4113.
6.3.2 Practices to Avoid When Applying Fertilizers Applying fertilizer directly to water bodies (streams, lakes, and swamps) un-
less specifically prescribed and approved for aquatic management. Applications of fertilizer within SMZs.
6.4 REVEGETATION AND STABILIZATION OF SITES
Forest management often creates openings in the form of roads, stream crossings, log decks, skid trails, and firebreaks. Establishing a vegetative cover as soon as possible on these sites reduces erosion and prevents sedimentation. In addition to protecting the soil, vegetative cover can enhance wildlife habitat. Establishing a vegetative cover may include selecting the proper plant species, preparing the site, liming, fertilizing, seeding and mulching. This section provides managers with a variety of seeding mixtures that stabilize sites quickly and also provide benefits to wildlife. Table 6-A on page 54 provides a quick reference to help with the selection and establishment of seeding mixtures. Selection of plant species, establishment methods and maintenance procedures should be based on site characteristics, including climate, soils, aspect and land-use objectives.
6.4.1 Land Preparation
Site preparation, such as smoothing or reshaping rutted roads and landings, may be necessary before conventional equipment can prepare seedbeds, which are important for vegetation establishment. Disc harrowing and dragging will firm and smooth soil and promote good germination. Heavily compacted areas may require sub-soiling, ripping or disking to allow water infiltration and to provide a suitable seedbed for root growth.

6.4.1.1 Fertilizer and Lime
A soil test can determine fertility and pH. If a soil test is not available and lime has not been applied in the past three years, apply it at the rate shown in Table 6-B. Lime and fertilizer are most efficient when incorporated into the soil. Spread them uniformly over the site prior to land preparation and mix them completely with the soil. Lime takes several months to react with the soil and become fully effective.
Forest soils are typically low in phosphorous and/or potassium and usually require lime. Clovers are not productive in acid sites (below pH 6.0) with low fertility unless fertilizer and lime are added.

Base additional applications of lime on soil test recommendations.

6.4.1.2 Seeding and Mulching
Seeding can be done in a number of ways. The most common method utilizes a farm tractor and a broadcast seeder. On steep or severely erosive sites, use a hydroseeder. Seed should be covered by pulling a section harrow, cultipacker, or brush.
Mulch should be used on slopes greater than five percent, on sites where vegetation will establish slowly, or on deep sands or heavy clay soils. Mulch helps prevent erosion and allows vegetation to become established. Structural measures such as a diversion, which moves concentrated runoff, usually require mulch. Where there is a danger of mulch being blown or washed off-site, anchor it by running over the mulched area with a disk harrow with the discs set to run straight. On steep slopes, anchor mulch with netting and tack-down staples or spray it with a tackifier.

Section 7.0
Additional Management Objectives
The Best Management Practices recommendations in this publication are directed at maintaining water quality, which is critical for the conservation of all natural resources. Forest management practices such as timber harvesting, site preparation, tree regeneration, and within-stand treatments may be conducted in ways that enhance fish and wildlife habitat, aesthetics and recreational opportunities, while accommodating sensitive sites and endangered species. Landowners may have other resource objectives that can be achieved only through the use of practices that vary but are consistent with the protection of water quality. The following comments describe additional management options that landowners may wish to consider.
7.1 WILDLIFE MANAGEMENT
Compare your current habitat conditions and those on adjacent lands to your wildlife management objectives before making land management decisions.
Some fish and wildlife species benefit from SMZs wider than the minimum widths specified for water quality BMPs.
Manage for a diversity of forest types and age classes to enhance wildlife habitat quality.
Maintain mature mast producing hardwoods in groups or stands. Leave corridors of trees connecting mature forest stands to provide food,
cover and travel avenues for wildlife while adjacent stands are regenerating. Leave snags, dead and down woody debris, brush piles or windrows through-
out timber harvest areas. Use prescribed fire, which is one of the most cost-effective forest and wildlife
management practices. Use wildlife-friendly plantings for log decks, roads and skid trails following
logging operations. For more information on any of the above recommendations, contact the
Georgia DNR Wildlife Resources Division.
7.2 PROTECTED SPECIES
The University of Georgia Cooperative Extension Service, the College of Agricultural and Environmental Sciences, and the Georgia Department of Natural Resources Wildlife Resources Division have publications with listings.
56

If you suspect the presence of an endangered species, contact the Georgia Department of Natural Resources Wildlife Resources Division or the U.S. Fish and Wildlife Service for verification and management considerations.

7.3 AESTHETICS

Consider aesthetics during forest

management activities and be

aware that appearance may

influence public opinion.

Use forest management methods

that can minimize visual impacts

such as single tree and group

selection, seed tree and shelterwood

regeneration, and small patch clearcuts.

Leave corridors of trees along welltraveled public roads to enhance visual quality.

Aesthetics can influence public perception of forestry.

Shape harvest areas with natural features of the landscape.

Re-seed bare soil areas promptly.

Maintain a mixed tree species composition.

During artificial regeneration, establish tree rows parallel to the road and

avoid 90-degree angles.

Minimize the "skylining" of residual snags and cull trees.

For more information, see the American Pulpwood Association's Forestry

Aesthetics Guide, Image and Opportunity.

7.4 SENSITIVE SITES
Consider protective management prescriptions for unique cultural (Native American sites), ecological (protected species), archeological (civil war breastworks), geological (rock formations), or historical (old forts and cemeteries) sites. They may need special consideration to manage their values. Contact the GA DNR.

8.1 FEDERAL LAWS AND REGULATIONS AFFECTING FOREST LANDOWNERS
8.1.1 The Federal Clean Water Act, Section 404, 40 CFR Part 232.3
Exempts normal, established, on-going, silvicultural operations from permitting.
Requires silvicultural operations to adhere to BMPs and 15 baseline provisions for forest road construction and maintenance in and across waters of the U.S. (lakes, rivers, perennial and intermittent streams, wetlands, sloughs and natural ponds) in order to qualify for the silvicultural exemption from the permitting process (See Section 3.3.1 page 31).
Requires Army Corps of Engineers permit for the conversion of forested wetlands to other uses such as agriculture or development.
A Memorandum of Understanding dated November 28, 1995, between the Army Corps of Engineers and the U.S. Environmental Protection Agency requires permits for the conversion of specific high-quality bottom land hardwood wetlands to pine plantations by mechanical site preparation methods. It also mandates the use of six BMPs in other jurisdictional wetlands (See Section 5.2.1.1, page 47).
Provides for civil and criminal penalties up to $125,000 per day.
8.1.2 USDA Programs
Participation by landowners in various loan, price support, agriculture, forestry incentive and assistance programs subject them to rules and regulations regarding the Federal Farm Bill (Swampbuster and Sodbuster Provisions). Prohibits landowners from converting forested wetlands to agricultural uses. Provides for penalties including program payments plus interest to be paid
back from the time of the conversion, loss of benefits and loss of eligibility in future programs.
8.2 STATE LAWS and REGULTIONS AFFECTING FOREST LANDOWNERS
8.2.1 The Georgia Water Quality Control Act (O.C.G.A. 12-5-29)
Makes it unlawful to discharge excessive pollutants (sediment, nutrients, pesticides, animal waste, etc.) into waters of the state in amounts harmful to
58

public health, safety, or welfare, or to animals, birds or aquatic life or the physical destruction of stream habitats. (See Section 1 or Glossary for definition of waters of the state.) Provides for civil and criminal penalties up to $100,000.00 per day.
8.2.2 (Excerpt from Georgia Rules and Regulations for Water Quality Control Chapter 391-3-6-.03 Water Use Classifications and Water Quality Standards) Amended.
General Criteria for All Waters. The following criteria are deemed to be necessary and applicable to all waters of the state:
Turbidity. All waters shall be free from turbidity, which results in a substantial visual contrast in a water body due to a man-made activity. The upstream appearance of a body of water shall be as observed at a point immediately upstream of a turbidity-causing man-made activity. That upstream appearance shall be compared to a point, which is located sufficiently downstream from the activity so as to provide an appropriate mixing zone.
For land disturbing activities, proper design, installation, and maintenance of best management practices and compliance with issued permits shall constitute compliance.
Temperature: Not to exceed 90F. At no time is the temperature of the receiving waters to be increased more than five degrees Fahrenheit above intake temperature, except that in estuarine waters the increase will not be more than one-point-five degrees Fahrenheit. In streams designated as primary trout or smallmouth bass waters by the Wildlife Resources Division, there shall be no elevation of natural stream temperatures. Streams designated as primary trout waters are waters supporting a self-sustaining population of rainbow, brown or brook trout. In streams designated as secondary trout waters, there shall be no elevation exceeding two degrees Fahrenheit natural stream temperatures. Streams designated as secondary trout streams are those with no evidence of natural trout reproduction, but are capable of supporting trout throughout the year.
Trout streams are classified in accordance with the designations and criteria established by the Georgia Environmental Protection Division. This list may be updated every two years. For the most current list, visit www.gaepd.org.

Authorized the Georgia Department of Natural Resources to develop minimum planning standards and procedures that local city and county planning and zoning jurisdictions could adopt and enforce pertaining to the protection of river corridors, mountain tops, water supply reservoirs/watersheds and wetlands.
Requires local governments to use these minimum standards in developing and implementing local comprehensive growth development plans.
Silvicultural practices are exempt from permitting requirements according to the guidelines, but the activity must comply with BMPs within these sensitive areas. The rules for environmental planning for each of these sensitive areas are:

8.2.3.1 Water Supply Reservoir/Watershed (Chapter 391-3-16-.01)
Provides local governments criteria to allow development of a water supply reservoir or watershed without contaminating the water source to a point where it cannot be treated to meet drinking water standards.
The criteria establishes buffer zones and requirements for land disturbing activities along perennial streams and lakes and applies to existing and future water supply reservoirs and watersheds (See Figures 8-A and 8-B).
Local governments may exempt specific forestry activities from the stream and lake corridor buffers, provided the activity complies with Best Management Practices.

8.2.3.2 Wetlands Protection Act (Chapter 391-3-16-.03)
Requires local governments and regional development centers to acknowledge the importance of wetlands for the public good in the land-use planning process.
Where wetlands exceed five acres, local governments are encouraged to protect them.
Timber production and harvesting are considered acceptable uses.
8.2.3.3 River Corridor Protection Act (Chapter 391-3-16-.04)
Requires local governments and regional development centers to use standards for the protection of river corridors in developing and implementing local comprehensive development plans.
Applies to any perennial river or watercourse, at that point and below, where the average annual flow is at least 400 cubic feet per second (cfs) as determined by appropriate U.S. Geological Survey documents.
Protected buffers include all land within 100 feet horizontally on both sides of the river, as measured from the riverbanks.
Plans shall allow for timber production and harvesting, provided the activity complies with Best Management Practices. Forestry practices are allowed within the 100 feet river corridor, provided the activity compiles with Best Management Practices.
See map (Figure 8-C).

8.2.3.4 Mountain Protection Act (Chapter 391-3-16-.05)
Requires local governments and regional development centers to use planning standards for the protection of mountain areas in developing and implementing local comprehensive plans.
Applies to all land area 2,200-feet or more above mean sea level that has a percentage slope of 25 percent or greater for at least 500-feet horizontally,
62

and shall include the crests, summits, and ridge tops that lie at elevations higher than any such area. Forestry practices are allowed on protected mountains, provided the activity complies with Best Management Practices. Figure 8-D. Generalized Map of Areas Subject to "Mountain Protection"

Section 8.0 Appendix
8.2.5 Metropolitan River Protection Act (O.C.G.A. 12-5-440)
Requires the Atlanta Regional Commission (ARC) to adopt a Plan that would protect the land and water resources of the Chattahoochee River Corridor from Buford Dam to the southwest edge of Fulton County.
Establishes a 2,000-ft. buffer in which land disturbing activities are regulated. Requires a 50-ft. buffer of natural vegetation be left in its natural state
along the banks of the river and 35-ft. along the banks of other tributaries. Outside of these buffers and in areas zoned for agriculture, forestry prac-
tices are exempt from permitting. However in residential or commercial areas, a plan must be submitted and approved by the ARC when removing healthy trees over two inches in diameter at breast height. Establishes civil penalties of $1,000.00 per acre per day or part thereof on which such violation occurs.
8.2.6 Georgia Forest Fire Protection Act (O.C.G.A. 12-6-90)
Requires any person, firm, corporation, or association entitled to burn any woods, lands, marshes, or any other flammable vegetation, whether in cultivated or uncultivated areas, to notify, prior to burning, and/or obtain a permit from the county office of the GFC wherein such burning is to be made.
Any person who initiates a burn and fails to give notice and/or obtain required permit shall be guilty of a misdemeanor.
8.2.7 Erosion and Sediment Control Act (O.C.G.A. 12-7-1)
Provides permitting by local issuing authorities for land disturbing activities. Exempts commercial forestry activities, including harvesting, from permit-
ting and minimum requirements of the act. Harvesting inconsistent with BMPs may be interpreted as being in association
with land conversion activities and trigger Erosion & Sediment Control permits and requirements.
8.2.8 Oil or Hazardous Material Spills or Release Act (O.C.G.A. 12 -14-1)
Requires producers of hazardous substances including used motor oils or fuels to collect those substances and deliver to registered handlers.
Requires that in the event of accidental spills, the spill be contained, contaminated soils be collected and delivered to approved waste handling facility, and EPD be notified. (1-800-241-4113)

8.2.9 State Board of Registration for Foresters Standards of Practice (O.C.G.A. 43-1-19) Chapter 220-5.01
It is the responsibility of each registered forester to practice professional forestry in a manner which protects the public welfare and safety and which meets generally accepted standards of practice.
Generally accepted standards of practice shall include, but are not limited to, adherence to Best Management Practices published periodically by the Georgia Forestry Commission and available from the Board office.
Failure to practice professional forestry in accordance with generally accepted standards of practice shall constitute unprofessional conduct and shall be grounds for disciplinary action as provided for by law.
8.3 LOCAL LAWS, REGULATIONS, AND ORDINANCES AFFECTING FOREST LANDOWNERS
Certain counties have adopted local laws and ordinances, which affect forestry activities. These come under the following categories:
8.3.1 Road Protection
May require permits and bonds before harvesting can begin. The Georgia Forestry Association, the Georgia Forestry Commission and the University of Warnell School of Forestry and Natural Resources Extension Service maintains current list of those counties.
8.3.2 Zoning
Timber harvesting, in other than agriculture zones, may require permits and specific harvesting requirements.
8.3.3 Timber Tax Collection
Certain counties require notification for timber harvest for the collection of timber tax.
8.3.4 Watershed Protection
Some counties require permits and plans for the removal of timber in floodplains.
8.3.5 Local Land Use Plans
See Comprehensive Growth Planning Act under State Laws. Landowners, forest managers and operators should check with local authorities before undertaking forestry activities.

8.5 GLOSSARY

Access Road A permanent or temporary woods road over which timber is transported from a

felling site to a public road. Also known as a haul or system road.

Aesthetics The study or practices designed to maintain the beauty of forests.

Aspect The compass direction that the slope of the land faces (north, northwest, south, etc.)

Back blading The practice of laying the bulldozer blade on the ground while operating a crawler

tractor or other bulldozer equipment in reverse. This practice is commonly used for smoothing

rough soil or for pulling soil or debris away from an area when pushing is not practical.

Backwater paleo channels Usually well-defined deep channel features that are remnants of

earlier river and side channel configurations. Mixed channel substrates (sand, organics, fine

sediments). Flow usually backs into these features from the main river. Organic debris is

often found piled against the "wrong" side of obstructions.

Backwater swamps Backwater swamps are wetland areas formed in old overflow channels

on the margins of floodplains at the base of the adjacent slopes. They feature wetland

vegetation, hydric soils, and fine and organic substrates, but they may show evidence of

scour and debris movement.

Basal Area The area of the cross-section of a tree stem near its base, generally at breast height

(4 feet above the ground), inclusive of bark. Expressed in square feet per acre. Stand basal

area is generally expressed as the total basal area per unit area.

Bedding A site preparation technique in which a small ridge of surface soil is formed to provide

an elevated planting or seedbed. It is used primarily in wet areas to improve drainage and

aeration for seedlings.

Best Management Practices (BMPs) Methods, measures or practices to prevent or reduce

water pollution, including but not limited to, structural and non-structural controls,

operation and maintenance procedures, and other requirements, scheduling, and

distribution of activities. Usually BMPs are applied as a system of practices rather than a

single practice.

Braided stream A stream flowing in several dividing and reuniting channels resembling the strands

of a braid. The divisions are caused by obstruction from sediment deposited by the stream.

Broad-Based Dip A surface drainage diversion built into the bed of a permanent haul road that

consists of a long approach section, a low, out-sloped middle section, and a short terminal

section with a reverse grade. They are specifically designed to intercept and divert surface

water flow out of a dirt road while allowing vehicles to maintain normal haul speeds. Also

called a rolling dip.

Broadcast Burn A controlled fire within well-defined boundaries to reduce forest fuel hazards.

Brush Barrier A linear pile of limbs, tops, logs, and other forest debris which is arranged

along the lower edge of a road, log deck, or site prepared area to slow, diffuse, or intercept

sediment moving off the disturbed site.

Buffer Strip A transitional area between two different land uses which mitigates the effects of

one land use on another. For water quality purposes they are intended to filter surface runoff

and trap sediment and associated pollutants before entering water bodies. Some state and

local regulations require them.

Canal A man-made waterbody constructed for the purpose of flood control.

Canopy cover Indices of percent ground surface shaded by a combination of overstory and

midstory trees.

73

is carried under roads or trails. Discontinuous side channels Channel features that may or may not be connected, on at least
one end, to medium or higher flow energy channels. May have distinct or indistinct channel features, but the channel features disappear and reappear. Ditch A man-made feature constructed for the purpose of minor surface water drainage. Drainage channels These less distinct channels begin on the floodplain and usually flow intermittently during periods of high water tables via a continuous linear drainage system to the main river. The channels often contain mixed substrates (sand, organics, fine sediments). Dry Wash A stream bed that carries water only during and immediately following rainstorms. Sometimes referred to as a gully or ephemeral stream. Duff Partially decayed organic matter on the forest floor. Ephemeral area Depressions or swales, sometimes called drains, draws, or dry washes, that have no defined continuous channel and that are well-connected to intermittent or perennial streams. Please see page 19 for a more detailed description. Erosion The process by which soil particles are detached and transported by water, wind and gravity to a point downslope or downstream.

Flora The plant of a specified region or time. Forest Chemicals Chemical substances or formulations that perform important functions in forest management, including fertilizers, herbicides, insecticides, fungicides and repellents. Gabion Large, multi-celled, welded wire or rectangular wire mesh boxes, used in stream channel revetments, retaining walls, abutments, check dams, etc to stabilize steep or highly erosive slopes.

Geowebb A heavy-duty polyethylene cellular confinement system used to improve and stabilize structural fill in roads and embankments. Gully Narrow ravines, often caused by past land cultivation. Please see page 21 for a more detailed description. Harrowing (Disking) A mechanical method of scarifying the soil to reduce competing vegetation and to prepare a site for seeding or planting. Herbicide Any chemical or mixture of chemicals intended to prevent the growth of or promote the removal of targeted tress, bushes, and/or herbaceous vegetation. Humus layer The organic layer of the soil formed by the decay of organic matter. Hydric Soils Soils exhibiting a considerably wet nature, typically characterized by dark or gray mottled colors and associated with wetlands. Hydrology The scientific study of the properties, distribution and effects of water on the earth's surface, in the soil and underlying rocks and in the atmosphere. Inslope The feature of a road surface, established during construction or maintenance, that slants the roadbed to the inner or uphill side to facilitate drainage of storm runoff from the road in more concentrated flow into a ditch line. Integrated Pest Management The maintenance of destructive agents, including insects, at tolerable levels by the planned use of a variety of preventive, suppressive, or regulatory tactics and strategies that are ecologically and economically effective and socially acceptable. Intermittent stream A watercourse that flows in a well-defined channel during wet seasons of the year but not the entire year. They generally exhibit signs of water velocity sufficient to move soil material, litter and fine debris. Aquatic insects often are difficult to find or not present at all. Log deck A place where logs or tree-length material is assembled for loading and transporting. Logging Debris The unused and generally unmarketable accumulation of large limbs, tops, cull logs, and stumps that remain after harvesting. Mulching Any loose covering of forest soil with organic residues such as grass, straw or wood fibers that checks erosion and stabilizes exposed soil. Non-point source (NPS) pollution Water pollution that is (1) induced by natural processes including precipitation, seepage, percolation and runoff; (2) not traceable to any discrete or identifiable facility; and (3) better controlled by using BMPs. Outslope The feature of a road surface, established during construction or maintenance, that slants the roadbed to the outer or downhill side to facilitate drainage of storm runoff from the road in more diffuse flow than occurs at dips and water bars. Outsloping is a contrasting road design to the crowned roadbed or to an inslope toward a ditch line.
