Executive Summary
Georgia's 24 million acres of forest land are a rich and renewable resource that provide a myriad of benefits to citizens across the state. Yet challenges to the land and the professionals who manage it abound. In this Statewide Assessment of Forest Resources, the Georgia Forestry Commission, partners and other stakeholders address the conditions and issues at hand today, and prioritize concerns for the near and distant future.
Georgia's current forest conditions link the land to a vivid history of species diversity, resource exploitation and appreciation. Today, forests with stands of varying ages account for 67 percent of the state's total land area. Forests thrive in six physiographic ecoregions and grow almost 56 percent more wood than is being harvested, producing 96 percent more cubic feet of wood than 50 years ago. The majority of Georgia forests are privately owned by individuals and corporations, with public lands accounting for just 10 percent. According to the Sustainable Forest Management in Georgia report, prepared for the Georgia General Assembly in July of 2008, and on which some of the findings of this Assessment are based, these forest lands are being sustainably managed to meet the numerous needs of our state today.
Georgia Benefits from its Forests A variety of benefits are provided to Georgia from its healthy, sustainable forests. Of primary importance is the $28.7 billion economic impact the forest industry has on the state. The industry is the state's second largest employer, with compensation exceeding $6.5 billion and payments to landowners of about $14.5 million. It generates an estimated $539 million per year in revenues for the state budget.
Forest-based recreation contributes to the state's economic growth and tourism industry. Georgia leads the nation in nonresident hunters, and resident sportsmen spend more than $1.8 billion annually. Anglers spend $569 million each year.
Importantly, Georgia's forests impact the state's ability to provide its citizens with vital nature services. Georgia's abundant water resources within 14 major river basins and multiple groundwater aquifer systems are enhanced by the healthy forest systems around and above them. Many of Georgia's 44,056 miles of perennial streams, 23,906 miles of intermittent streams and 603 miles of ditches and canals begin or flow through forest lands. Forests afford value through filtration and stormwater management services, reducing costs to water authorities. Georgia forests also improve air quality, with metro Atlanta trees removing some 19 million pounds of pollutants, a $47 million value, in 1996 alone. Trees help moderate the heat island effect caused by pavement and buildings, create energy savings through shading and sequester atmospheric carbon, which benefits human health and may benefit Georgia landowners through emerging reimbursement systems.

Georgia is beginning to benefit from the state's emerging bioenergy industry. Residues from timber harvesting exceeded 7.4 million tons (oven dry weight) in 2007, and a recently performed forest biomass assessment based on forest inventory data gathered between 1995 and 2005 showed that on average 18.1 million tons (oven dry weight) of biomass are available annually in Georgia. This growing opportunity for new markets from previously unutilized and low value forest biomass will add to the economic impacts of Georgia's forest industry.
Additional benefits to Georgia from its healthy forests include enhanced wildlife habitats and plentiful aesthetic and education opportunities.
Leading Threats and Pressing Issues Forest issues ranked most critical by the public and identified in the 2008 Sustainable Forest Management in Georgia report include a number of threats which present significant challenges to forest managers, landowners and civic leaders. They are interrelated and often complex. Conservation was a highly ranked public concern that affects and is interwoven with every issue; it is not individually analyzed in this report.
Water quality is the public's primary issue of concern. Urbanization and nonpoint sources of pollution are the greatest threats to Georgia's water quality. Urbanization removes acreage from forest cover, resulting in increased storm runoff and intensified streamflow that causes stream bank erosion, sedimentation and flooding. Currently, more than 6,000 miles of streams do not meet state water quality standards due to nonpoint sources of pollution. Magnifying the threat is the problem that Georgia does not have systems in place that measure stream and aquifer water output or pollution capacities, making water projections impossible to gauge. Specific regional water priority issues are detailed in this report.
The urbanization of Georgia is a serious threat that could undermine forest sustainability in decades to come. Georgia is home to four of the nation's 20 fastest growing counties and the state's population is projected to increase by an additional 46 percent in the next 20 years. From 2001-2005, Georgia's canopy cover declined by a total of 398,330 acres and impervious surfaces increased by 106 acres a day. Much of this growth occurred in metro Atlanta, though the Savannah, Columbus and Macon areas reflected significant changes as well. Population increases and the loss of tree cover to impervious surfaces impact every forest benefit. Proactive management tools and technical support systems are needed to adequately protect Georgia's forest resources.
Forest fragmentation and parcelization are additional challenges caused by urbanization. These phenomena are created when forests are converted to other land uses and when the number of forest landowners increase, but the land parcels shrink in size. Contributing factors include urban sprawl, inheritance issues, tax implications, timber land divestitures, investment concerns or other financial pressures. Taxation issues also play a part as land values rise but income from forest uses does not. The global recession and economic pressures of global competition have compounded these issues. Likewise, these situations can lead to a decreased value for forest management, and an increased occurrence of water quality degradation, wildlife disruption and forest pest incidence.
2
Urbanization and resulting forest land losses place extraordinary stresses on wildlife and biodiversity. While some species have adapted to changes brought on by growth, others are in need of more careful management to prevent further declines in habitat loss. Georgia ranks fifth in the nation in number of species extinctions and eighth for species at risk. A system of public and private conservation strategies, including expansion of the Georgia Land Conservation Program and the State Wildlife Action Plan, support this goal.
Air quality and carbon sequestration are additional opportunities. Urbanization affects Georgia's tree canopy, diminishing forestry's ability to provide clean air nature services. Georgia's new Carbon Sequestration Registry is being developed to assist landowners with garnering new income from timberland while air quality is positively impacted by the sequestration of carbon emissions statewide.
Urbanization puts more lives and property at risk from wildfire and reduces options for proper fire management, including prescribed burning. Tactics and strategies for fire management and suppression are compromised in the wildland urban interface, where access challenges, liability and logistics can complicate response. Some 12,000 Georgia communities are rated by the Southern Wildfire Risk Assessment at high or very high risk of wildfire. In addition, air quality regulations, resident fears and misunderstandings about prescribed burning and smoke effects can hinder the effective use of this forest management tool.
Economics and changing markets must be considered in order to increase the value of forests and forest products for continued industry growth. Traditional forest product markets have declined, but forest growth exceeds removals and is available to supply local and global markets. Bioenergy markets are believed to hold great potential for Georgia.
Significant forest pests threaten Georgia, including the southern pine beetle, hemlock woolly adelgid, redbay ambrosia beetle, annosum root disease, gypsy moth, Sirex noctilio woodwasp, emerald ash borer and Asian longhorned beetle. The highest priority invasive plant in Georgia is cogongrass, listed as the seventh most noxious weed in the world. Chinese privet, kudzu, Japanese climbing fern and Chinese tallowtree continue to threaten native plants. Trees that are weakened by pests and disease are at added risk of wildfire. Legislative support and regulation are needed to prevent the spread of these destructive threats.
Unusual weather events and the potential for climate change also threaten Georgia's forests. Thousands of trees are lost annually to wind, ice, flooding, drought and lightning, with damages exceeding $10 million every year, not including future liability problems. These occurrences can affect the incidence of wildfire in Georgia's forests and are predicted to intensify challenges for wildland fire managers.

Georgia's diverse landscape and population centers contribute to the definition of six priority resource areas from the Blue Ridge Mountains to the East Gulf Coastal Plain. The priority areas were determined by evaluating percent coverage of core forest areas greater than 250 contiguous acres. These core areas are large enough to be managed to provide for critical ecosystem services. The 12-digit Hydrologic Unit Codes (HUCs) were selected as a bounding area because they, for the most part, represent a consistent area of approximately 45km2. Areas that were represented by 30 percent or greater coverage of a HUC by core area forests were selected. Watersheds were then merged and six priority areas were defined. They include: Blue Ridge, Ridge and Valley, Fall Line, Large River Bottomlands, Atlantic Coastal Plain and East Gulf Coastal Plain. The Assessment details the predominant forest issues contained in each distinct region.
The Georgia Statewide Assessment of Forest Resources is a comprehensive and thorough analysis of one of the nation's most abundant and productive expanses of natural splendor. The prudent use of the assessment tool can ensure that this valuable resource is sustained for every future generation.

The 2008 Farm Bill calls for three components in the assessment and planning that identify priority forest landscapes and the work needed to address forest management priorities: Statewide Assessment of Forest Resources, Statewide Forest Resources Strategy and Annual Report on Use of Funds.
Statewide Assessment of Forest Resources To ensure that federal and state resources are being focused on landscape areas with the greatest opportunity to address shared management priorities and achieve measurable outcomes, the Georgia Forestry Commission has collaborated with key partners and stakeholders. The result is a comprehensive analysis of the forestrelated conditions, trends, threats and opportunities found on all forest ownerships within the state.
Georgia's Assessment is the product of work with the Forest Stewardship Coordinating Committee, Georgia Department of Natural Resources' Environmental Protection Division and Wildlife Resources Division, Georgia Soil and Water Conservation Commission, Georgia Urban Forest Council, National Wildlife Refugees, Natural Resource Conservation Service, State Technical Committee, U.S. Forest Service and other natural resource entities.
The cornerstone of the Assessment is the Sustainable Forest Management in Georgia report. In 2007, the Georgia General Assembly enacted into law Senate Bill 176. It requires the Georgia Forestry Commission (GFC) to submit a report to the General Assembly every five years which summarizes the sustainability of the state's forests. Specifically, the bill requests verification of "the ability
of forest resources in this state to meet the
needs of the present without compromising
the ability to meet the needs of future generations." The report, submitted to the General Assembly on July 1, 2008, highlights the current forest resource conditions, along with the challenges and opportunities being faced by Georgia's forest managers and owners. It concludes that while Georgia's forests are being sustainably managed for the numerous needs of the state today, their future viability will be determined by specific actions of state leaders and the forestry community.
To gather further information relevant to key state issues and national themes, the GFC conducted a public survey. Top Georgia issues ranked in order of importance include: Water Quality, Urban Sprawl, Conservation, Taxes, Biodiversity, Forest Health, Air Quality, Fire Management, Fragmentation/Parcelization and Changing Markets. In addition, GFC contracted with the University of
Georgia College of Agriculture and Environmental Sciences to develop geospatial data layers for use in identifying priority forest landscapes. This geospatial data, together with issues identified in the 2008 Sustainable Forest Management in Georgia report, laid the foundation for developing an Assessment that accomplishes the following:
Identifies forest-related benefits and services consistent with the 2008 Farm Bill national priorities.
Delineates priority rural and urban forest landscape areas to be addressed by the Statewide Forest Resources Strategy.
Identifies areas of regional priority through work with adjoining states.
Incorporates and complements existing statewide plans and assessments including the Comprehensive Statewide Water
Management Plan, A Comprehensive
Wildlife Conservation Strategy for Georgia, National and Southern Cohesive
Wildfire Management Strategy, Community Wildfire Protection Plans, The Five-
Year Plan for Georgia's Urban and Community Forest 2007- 2011, the Georgia Invasive Species Strategy and the Southern Wildfire Risk Assessment, and addresses existing S&PF program planning requirements.
This Assessment serves as the basis for development of the Statewide Forest Resources Strategy.

Historical Growth, Harvesting and Reforestation Georgia's forests are currently growing almost 56 percent more wood than is being harvested on an annual basis. Timber volumes have been increasing since 1953, which means that today we have 96 percent more cubic feet of wood growing in Georgia than we did 50 years ago (Figure 3).
Tree planting after harvest has been a major contributor to increasing timber volumes, and federal tree planting cost-share programs have positively influenced replanting.

Ecological Regions
The six physiographic ecoregions of Georgia are the Southern Coastal Plain, Southeastern Coastal Plains, Piedmont, Blue Ridge, Ridge and Valley and Cumberland Plateau (Figure 5).
The Southern Coastal Plain and Southeastern Plains, collectively referred to in this report as the Coastal Plain, are comprised mostly of loblolly, slash and longleaf pine and lowland hardwoods. The Piedmont is comprised mostly of loblolly pine, loblolly pine-hardwood mix, with small percentages of shortleaf pine, upland hardwoods and lowland hardwoods. The Blue Ridge has a majority of upland hardwood types with small percentages of white pine and hemlock types. The Ridge and Valley region varies between upland hardwoods on the ridges to mostly loblolly pine and Virginia pine in the valleys and lower slopes. The Cumberland Plateau, which only includes Dade County in extreme northwest Georgia, is comprised mostly of upland hardwoods, with some loblolly pine and Virginia pine.

Stand ages vary across the state
(Figure 6), with most of the oldest
stands located in the northeastern
mountainous terrain (owned primarily
by the USFS) and the floodplains and
lowlands across the state. Pine stands
across the state tend to average lower
in age than hardwood stands, mostly
due to the increased probability of
active forest management, including
harvesting. The older hardwood stands
often occur on steep slopes, land that
is difficult to access due to lack of
roads, and floodplains/swamps where
logging is difficult, except perhaps in
the driest conditions. Also, publicly
owned lands, on which harvesting is
very limited, tend to have older
stands.

Forest Types
Hardwood forest types comprise 41 12 percent. One percent of the percent of Georgia's 24.8 million forested area is non-stocked, i.e. acres of forest land. Softwood recently harvested land that has (mostly pine) occupies 45 percent not yet seeded or been planted with and mixed oak/pine accounts for seedlings (Figure 14).

Comparing the 2008 forest cover map with the 1941 map (Figures 16 and 17) shows some significant differences. One is the prevalence of the shortleaf pine component in the Piedmont in 1941 compared to 2008. Today it is rarely more than a minor component in any pine forest type with loblolly pine being by far the major pine species in the Piedmont.
Historically, shortleaf pine appears to have been a major component of many upland hardwood types even into the Blue Ridge. Today, Virginia and loblolly pine are the more common components of these upland hardwood stands with more pure stands of upland hardwood becoming common as the pine component died out. Longleaf
pine in the Coastal Plain was more prevalent in 1941 than it is today. Now, slash and loblolly (planted) pine are the predominant pine species in the Coastal Plain. Georgia and several other southern states are collaborating to reintroduce longleaf pine throughout its natural range.

Forest Ownership
This graph below shows the changes in acreage of forestland owned in each
ownership class from 1953 2013. The majority of Georgia's forestland is
owned by private individuals. Forest industry purchased private forests in the
1950-70's, and this trend reversed in the 1990's through today as industry sold
lands to private holders as well as corporate entities (such as Real Estate
Investment Trusts or REIT's, and Timber Investment Management
Organizations or TIMO's).

General Management Objectives
of Family Forest Landowners
in Georgia Georgia landowners have many reasons to own forest land, but when surveyed by the U.S. Forest Service through the National Woodland Owner Survey (NWOS) regarding their reasons for owning forest land, the landowners' answers correlated closely with their size of forest tract owned.
As shown in Table 1, owners of the smaller acreages (<500 acres) of forest land gave reasons of being part of a home, passing on to heirs, enjoying the beauty of the forest and land investment as their primary reasons for ownership. Those who
owned 500 or more acres listed timber production as their number one reason for ownership and enjoying the beauty of the forest and passing the land on to heirs (and vice versa for 1000+ acres) as their second and third reasons.
The results of the NWOS Survey support the belief that private landowners are more likely to actively manage their forest land if they own larger tracts. In the interest of preserving the wise management of forest land in Georgia, an important factor is discouraging rather than encouraging the subdivision of large tracts. Selling and/or subdividing often occur(s) as a result of large tax costs passed on to heirs when a
forest landowner passes away. The inheritance tax is, therefore, a strong barrier to sustainable forest management. Large forest land tracts are critical to maintaining the forest product supply chain and for sustaining product .
The continued sustainability of Georgia's forests falls largely on individuals and corporations. These landowner groups are facing new challenges that will determine the future of Georgia's forests. State and local tax structures and cyclical forest product markets will have a major impact on these landowner decision makers.

The forest industry is the second largest industry sector in Georgia based upon wages and salaries (behind food processing), and the third largest based upon employment (behind food processing and textiles).
The forest industry generates an estimated $746 million per year in revenues for the state budget. When the costs of providing state services to Georgia's households and companies associated with that activity are deducted from these revenues, net annual state revenues are more than $365 million, an increase of 51% from 2012 and more than double the revenue since 2011.
In addition to the economic benefits outlined above, Georgia's 24 million acres of forests provide non-timber ecosystem services (clean air, clean water, wildlife habitat, and carbon sequestration) valued at over $37.6 billion annually to society.
Economic Impact by Region Local economies are impacted by the forest industry by supporting employment, bringing in additional dollars, and recirculating the dollars across local businesses. In regions where forestry is a large proportion of the local basic industry, all economic support is generally dependent on it in some manner. Figure 21 shows Georgia's 12 regional commissions.
Employment by Region: The Atlanta Regional Commission, Coastal Regional Commission, and Heart of Georgia Altamaha are the top three commissions in terms of employment, accounting for 45% of the forest related jobs in Georgia. However, Heart of Georgia Altamaha, Southwest Georgia, and Central Savannah River Area have the three highest employment percentages compared to total employment at 4.9%, 2.9%, and 2.5%, respectively.
Compensation by Region: The three regions with the greatest dependency on forest based compensation compared to total compensation are Heart of Georgia Altamaha, Southwest Georgia, and Southern Georgia with 9.5%, 5.1%, and 4.7%, respectively. The Atlanta Regional Commission provided the most compensation at $861.1 million; however, that accounted for only 0.8% of the region's total compensation.

In addition to federal payments via various cost-share programs, Georgia's 500,000 timber owners received an average of $577 million per year in timber harvest income from 2000 to 2007. Statewide timber sale values totaled $4.6 billion during this period. In 2006, as reported on the 2007 tax digest, timber was harvested on 3,129,223 acres with an assessed value of $564,231,554. Table 2 shows the timber revenue generated from these timber sales (Graham 2009).

Timber Products
Georgia has 143 primary woodusing industries with 95 sawmills, 10 veneer and panel product mills, and 38 mills that produce other valueadded products from logs. In addition, Georgia has 12 pulp mills, 22 chip mills and six log and/or wood chip exporters. Thirty-one primary mills export products to world markets. Of Georgia's 159 counties, 83 counties have at least one primary mill; 76 counties have none. The top three counties in terms of number of primary mills are: Clinch-6; Ben Hill-5; and Wilkes-4. Eleven counties have three mills; 26 counties have two mills and 43 counties have one mill. In addition to the primary mills, approximately 1,066 secondary manufacturers provide further processing to Georgia's wood products (Willard 2015).

Clean Air
Trees and forests store carbon in roots, trunks and limbs. This helps to remove atmospheric carbon, a by- product of burning fossil fuels, and thus reduces pollution. Carbon accounts for about half the dry weight of most trees. The carbon- related function of trees is measured in two ways: the total amount stored, which becomes greater as the tree ages, and the rate at which carbon is stored (called sequestration), which is faster in young trees and then slows as the tree matures. This stored carbon has the potential to be saved for a long period of time in both living trees and solid wood products.
In addition, carbon se- questration is an emerg- ing ecological market opportunity for forest owners.
"Han et al. (2007) estimated current forests in the South sequester 13% of regional greenhouse gas emissions9. A study of feasibility revealed the potential of up to 200 million pounds of CO2 equivalent across southern states at a price of $30 per metric ton10, with another study showing a potential of 500 million metric tons for the U.S. for $30 $90 per ton11."
planted and natural stands represent 31% and 69% of total carbon sequestration, respectively. This yields an average of 64.4 metric tons per acre for all of Georgia timberland (Brown, Jonathan. Georgia Forestry Commission. 2013 Carbon Sequestration of Georgia Timberland. June 21, 2015).
Figure 25 shows that 0-60 year-old, planted stands sequester more carbon on a per acre basis than natural stands. It also indicates that the majority of planted stands over the age of 60 have been thinned heavily, reducing sequestration to approximately 45 metric tons per acre for the age class of 61-80 years.
Furthermore, 97% of carbon sequestered in planted stands is under the age of 40 (Table 5). Natural stands show a continued increase through 100 years of age due to the longer rotations required for hardwoods. However, according to a publication by the U.S. Forest Service, despite the increased rotation length of natural stands, shorter rotations result in a greater amount of total carbon converted to wood products over a 100-
year period and should be considered an
important avenue of sequestration
(Johnsen, Kurt, et al. Meeting Global Policy
Commitments: Carbon Sequestration and
Southern
Pine Forests. (2001).
http://www.srs.fs.usda.gov/pubs/ja/ja_
johnsen007.pdf. 15 June 2015). Under
the age of 40 and 60, total carbon
sequestered is 59% and 78%,
respectively (Figure 26). Therefore,
reforestation of properly managed
timber on younger rotations will be
critical in maximizing Georgia's carbon
sequestration.

Clean Air
As shown above, growing trees is a viable and proven avenue for reducing atmospheric carbon. In addition, the sale of "carbon credits" may provide a potential opportunity for new income to Georgia landowners. For example, "using forests to capture and store CO2 is equivalent to using new technology to capture and store carbon directly from coal plants, while being less costly and proven to work. Encouraging investment in enormous opportunities to limit carbon in our atmosphere through sequestration and offsets should be considered" (Georgia PSC).
Some conservation groups question the sustainability of Georgia's forests to supply an increasing demand for wood pellets. However, the majority of timberland is managed for highervalued products (such as sawtimber, poles, etc.), which continue to sequester carbon as finished products, while trees may be replanted to provide additional sequestration in place of the harvested timber. The volume ratio of growing stock (sawtimber-potential trees 5+ inches in diameter) to total live trees, for all private timberland is 86%. Planted and natural stands are 94% and 83% growing stock, respectively. Therefore, roundwood sold to pellet mills will only include trees of inferior quality or size that would not otherwise have the capability of producing sawtimber. In most cases, utilized biomass is timed at the maximum volume the stand can reach without mortality occurring due to self-thinning, which maximizes growth for highervalued products that will be utilized in future harvesting operations.
Finally, the biomass market should help encourage timberland owners to replant, taking advantage of stronger markets. Reducing the available markets will only pressure land conversion for commercial development or other non-forest use as Georgia's population continues to rise. With a continuous demand for energy, utilizing Georgia's renewable resources through sustainable forest management will maximize carbon sequestration without compromising the economical or ecological benefits of timberland.

Energy Conservation
Energy savings provided by trees by the necessary power generation can be significant. Nationwide, it is (Galveston-Houston Association estimated that planting trees and using for Smog Prevention 1999). Three more light colored surfaces (roofs and properly-placed trees can save the pavement) could annually save up to average household between $100 40 billion kilowatts of electricity and and $250 in energy costs or about the attendant pollution produced 30 percent on air conditioning costs
every year.
Avoided Carbon Reducing energy use also decreases the amount of carbon pollution produced by utility companies. A CITYgreen calculation (that multiplied the amount of kilowatt hours of electricity conserved as a result of direct shading of trees by the fuel mix profile of Georgia's electricity production) revealed that Atlanta eliminates about 658,000 tons of carbon emission annually as a result of direct shading (American Forests 2002).

Threats to Forest Resources
Urbanization and Changing Land Uses
Furthereffectsof forestcoverlossinclude higher levels of pollutants and increased water temperatures that degrade fish and wildlife habitat. Development in the wildland-urban interface often occurs in the headwaters of streams and rivers that are home to many of Georgia's endemic species which are vulnerable to environmental changes and pollutants.
There are inconsistent standards for managing riparian management zones among land users. For example, state law requires developers to maintain only a 25-foot undisturbed management zone along most streams, regardless of the pitch of slopes that are perpendicular to the stream. Forestry operators, however, recognize a 40-foot minimum management zone, which can increase to 100 feet, depending on the slope or whether the stream is identified by DNR as a mountain trout stream.
Critical Water Projection
Data Needed Regarding quantities of water available for the state's growing needs, Georgia does not have precise measurements of how much water is available from its streams and aquifers. Calculations are also unavailable for how many waterborne pollutants Georgia streams and rivers can safely assimilate. No reliable forecasts have been made concerning how much water the state will need, or how much wastewater will be discharged, as the state continues to grow. Accurate information is needed on water quantity as well as water quality for effective planning and management. Georgia must determine how much water can be removed from rivers, lakes and aquifers without causing unacceptable negative impacts and determine how much wastewater and stormwater streams can handle before water quality begins to degrade.
In addition to urban pressures, the Georgia Comprehensive Statewide Water Management Plan (Georgia DNR 2008)states that there are over 6,000 miles of streams that do not meet state water quality standards because of nonpoint sources of pollution. Nonpoint sources include forestry activities. It has been estimated that seven to ten thousand forestry operations are conducted on some 790,000 acres per
year statewide. Other nonpoint sources include agriculture, past practices of constructing canals and ditches and poor county road maintenance. These have contributed to impaired streams and wetland losses (Figure 27).
Declining budgets have affected state and local regulatory agencies' abilities to effectively address water quality and quantity issues.

Threats to Forest Resources
Urbanization and Changing Land Uses
Urbanization and Biodiversity Most of Georgia's native plants and animals depend upon healthy forest habitats for survival. High quality forest habitat is being lost to development and conversion to other uses to meet the desires of our growing population and changing society. Contributing factors include urban sprawl, tax laws and economic factors that encourage parcelization and development, global competition for forest products, intensifying forest management practices and widespread corporate divestiture of timberlands.
Forest habitats in decline include mature bottomland hardwoods and cypress-gum wetlands (U.S. Forest Service 2008). Imbedded within forests are small patches of special habitats such as bogs, rock outcrops, caves and prairie remnants that are essential for numerous localized and rare species.
Wildlife Species' Ups and Downs Examples of high priority large-patch or "matrix" habitats that support substantial numbers of wildlife species
include upland hardwood and pinehardwood forests, pine woodlands and savannas, bottomland hardwood forests, river swamps, and depressional wetlands (Georgia Department of Natural Resources 2005; Comer et al. 2005;Van De Genachte and Cammack 2002). Often embedded within largepatch habitats are small-patch natural communities such as bogs, rock outcrops, caves and prairie remnants that represent essential habitat for many localized or rare species. Both "matrix" and small-patch habitats are impacted by habitat fragmentation and disruption of natural ecological processes such as fire and flooding.
Over time, some species have successfully adapted to extensive landscape changes resulting from residential and commercial development, agriculture, intensive forestry, stream impoundment, pollution and additional factors that have accompanied human population growth and a high rate of natural resource consumption.
However, other species are less adaptable and are in need of careful management
to prevent further declines in the face of extensive habitat loss. For example, populations of the northern bobwhite, Bachman's sparrow, redcockaded woodpecker, prairie warbler and many others that once occupied the extensive and highly diverse longleaf pine savannas of the coastal plain, characterized

by open forest canopy with herbaceous ground cover maintained through frequent fire, have all decreased as their habitats have dwindled.
Many aquatic organisms have declined as a result of impoundments, siltation, pollution and competition from exotic species. Georgia ranks eighth among all states in the number of species at risk and fifth in the number of extinctions.
Also, the growing wildland-urban interface compounds other problems, including conflicts between wildlife and humans, pets and livestock. Of particular concern is the increasing number of wildlife and car collisions. With the deer population hovering around 1.2 million statewide, and continued urbanization and development, there are an estimated 50,000 deer-car collisions annually in Georgia.

Threats to Forest Resources
Urbanization and Changing Land Uses
Urbanization and Wildfire Urbanization places more lives and property at risk from wildfire and reduces options for proper fire management. The most important function/work management challenge for forestry professionals is to ensure public safety by providing fire prevention ser vices through prescribed fire as well as wildfire suppression. The sustainability of Georgia's forest is dependent on attention to both of these critical services.
Urbanization makes wildfire management complex. Tactics and strategy, roles and responsibilities, coordination of responders, media relations, liability, planning, logistics, finances and firefighter safety become more difficult to manage in the wildland-urban interface (WUI). Preparation of forest rangers and cooperators for WUI wildfires requires additional, intensive training at considerable expense.
Prescribed Burning Challenges Increasing urbanization challenges Georgia's ability to maintain or increase the million-acre prescribed fire program. This program is GFC's best fire prevention tool for mitigating wildfire threat. As Georgia's population increases, it takes extra time and effort to consider how every prescribed fire
impacts communities. Prescribed fire managers are trained to minimize smoke impacts on the public and to communicate fire projects to neighboring communities. Planning and execution of prescribed fires become increasingly complex, requiring critical decisions and better trained practitioners. However, extra precautions increase costs and reduce the cost/benefit ratio of prescribed burning. Although the threat of wildfire may be reduced for communities through prescribed fire, few communities have been motivated to help alleviate costs for this practice that ensures forest health and reduces wildfire risk.
Apprehension about fire and smoke increases with urbanization. Air quality has become a major concern in Georgia, and prescribed fire has been targeted as one of many sources of harmful emissions. Drift smoke from prescribed fire and wildfires concerns urban dwellers. An important mission is to help Georgians understand the life sustaining properties of healthy forests, and the natural role that fire plays in ecosystems.

Results showed forest core areas greater than 500 acres have decreased by more than 20 percent (Figure 28).
This core size represents large, contiguous forest area available to provide abundant amounts of key ecosystem services including wood and fiber production, water quality and quantity protection and biodiversity. Some of this loss is accounted for in the increase in developed area across the state, but the biggest reduction in large core areas is in fragmentation due to the changes in land ownership and priorities of these land owners over time. Much of the loss of large patches can be accounted for in the increase in area of smaller core patches and increases in edge, patch and perforated patches (Table 6).
In addition to urban sprawl, a major

Threats to Forest Resources
Changing Markets
Certified Wood Products The use of products that have been "certified" as friendly to the environment has also increased, due to green building standards, government regulation and pressure on product retailers from environmental groups. The certification trend began as a concern about poor logging practices and negative social impacts in developing countries' tropical forests. Demand for certified wood products now dominates the furniture industry and is quickly growing in the building industry, where it is a cornerstone of the "green" building movement.
While the use of wood originating from well managed forests is prudent, participation in certification programs is costly and has only been slowly adopted by small non-industrial forest landowners in Georgia. Georgia currently has 2 , 5 6 0 , 6 7 7 acres e n r o l l e d in the Sustainable Forestry Initiative, 2,313,785 acres in the American Tree Farm System and 31,757 acres of forest land under Forest Stewardship Council certification, for a total of 4,906,219 acres, or 19.8% of forestland in the state (Dru Preston. March 18, 2015. Georgia Forestry Commission). Most Georgia forest product mills do not track chain of custody from these forests for their products. In addition, some green building standards do not accept all certification systems. Georgia landowners and forest product manufacturers may not have access to certified product markets, unless increases in the adoption of these systems occur.

Significant Forest Pests
Southern Pine Beetle The southern pine beetle is the most destructive forest pest in Georgia. It attacks and kills all pine species in Georgia. Historical financial losses from this species surpass all other forest pests combined.
The southern pine beetle is a native insect with a history that stretches back to the 1700s, when early settlers to America noted widespread mortality of southern yellow pines. Although a tremendous amount of research has been conducted over the past 50 years, no effective control measures have been developed for trees that have been attacked. Beetle populations tend to be cyclical. Epidemic levels can last for two to three years and can occur every five to fifteen years, depending on the region of Georgia, environmental factors and overall health of the area's pine forests. Historical outbreaks are shown in Figure 29.
Stands of overstocked pines that have poor vigor and health suffer much greater levels of damage following pine beetle attack. Lack of forest management practices that control stand density and promote vigor further endangers Georgia's pine forests. Southern pine beetle threat for Georgia is based upon stand density, site factors, pine species and other information.

Hemlock Woolly Adelgid
The hemlock woolly adelgid (HWA)
is a serious pest of eastern and Caro-
lina hemlock trees in Georgia. It is
an aphid-like insect that feeds on the
sap of hemlock trees. The adelgid is
dispersed by wind, birds and human
activity and is spreading at an alarm-
ing rate.
HWA was accidentally introduced
into Virginia in the 1950s. The in-
sect is native to Japan, China and
the United States' Pacific Northwest.
HWA was first discovered in Georgia
in 2003 near the Ellicott Rock area
of Rabun County and can now be
found in almost all Georgia's moun-
tain counties where native hemlock
occurs (Figure 30). All ages and
sizes of hemlocks can be attacked.
HWA causes damage to the tree by
feeding at the base of needles,
causing them to desiccate and drop.
This inhibits the trees' ability to
produce new growth. Trees that have
been infested for a couple of years
will show signs of decline.
Unhealthy hemlocks will appear a
dull green to gray color and exhibit
branch dieback. Tree death can
occur after as few as four years of
infestation.

Laurel Wilt Disease (and redbay
ambrosia beetle) Laurel wilt disease (LWD), caused by the fungus Raffaelea lauricola and vectored by the redbay ambrosia beetle (RAB), Xyleborus glabratus, was introduced from Asia through the Port of Savannah in solid wood packing material. The first RAB was caught in an early detection rapid response (EDRR) monitoring trap in Garden City, GA in 2002 and dead redbay trees were evident near the coast in GA and SC by 2004. Since then, the disease has spread rapidly throughout the coastal plain forests in Georgia, South Carolina, and Florida, killing all large, previously abundant redbay and swamp bay trees in its path. More recently, LWD has spread into redbay in the coastal plain of North Carolina and has been documented in distant, isolated locations in the panhandle of Florida, Alabama, Mississippi, and northern Louisiana, with the newest introductions being found exclusively in sassafras species.
Laurel wilt is a disease of plant species in the family Lauraceae, and the disease has been identified in plants of the federally endangered pondberry (Lindera melissifolia), the threatened pondspice (Litsea aestivalis), and avocado (Persea americana).
Georgia now has over eight million acres that are confirmed with laurel wilt (Figure 31), and the disease advances in surges and disconnected jumps, with most new county detections being found in sassafras trees in the absence of known redbay populations.

Southern Mexico and Central America have many species within the Lauraceae family, and host-testing on some of them has revealed a susceptibility to the pathogen, prompting concern about potential impacts to the forests there as well. The primary agricultural crop threatened is avocado, and a great deal of research into the situation is ongoing in south Florida.

Heterobasidion Root Disease (Formally Annosum root disease) Heterobasidion root disease, caused by Heterobasidion annosum, can be a se- rious problem in pine plantations that have been thinned one or more times. All southern pines are susceptible, but loblolly, slash and white pine are the most vulnerable. H. irregulare causes decay in the root system, making the trees subject to butt rot, windthrow, decreased growth and death. Bark beetles can become established in diseased trees and spread to healthy ones, leading to greater losses.
The fungus usually enters a healthy stand by infecting freshly cut stump surfaces. Airborne basidiospores of the fungus land on a stump's surface, germinate and colonize the stump and its root system. The fungus then spreads to adjacent trees by root grafts or contacts, causing root disease and a decline in tree health. When two or more main lateral roots are killed, tree death usually occurs. Damage within a stand can range from single trees to pockets of dead trees scattered throughout the entire stand. If the damage is widespread, Ips and black turpentine bark beetles often cause further mortality by at- tacking the weakened trees.
Damage has not occurred on a significant scale throughout the state, but is concentrated in areas along the Fall Line and southward, particularly where sandy soils are found (Figure 32). Tree decline and death can occur from soon after the harvest up to seven years hence, with peak mortality occurring from two to five years following harvest. Georgia be-

Pests Not Naturalized in Georgia
Gypsy Moth The gypsy moth (Figure 33), a federally regulated pest, is a serious forest pest capable of causing severe damage to hardwood trees, especially oaks. This damage is inflicted as the gypsy moth larvae defoliate entire stands of trees. Defoliation during the spring causes severe stress on trees and can cause mortality in unhealthy individuals, but multiple years of defoliation will cause mortality in healthy stands.
Figure 33
Gypsy moths were brought into Massachusetts in the late 1800s, with the intent to farm the moths for silk produced by the larvae. It wasn't long before the moths escaped captivity and moved into the surrounding woodlands. Many northeastern states (Virginia northward and west to Illinois) now have established populations. The natural spread of gypsy moths occurs as newly hatched larvae spin long silk threads and ride on the breeze. Active populations in Tennessee and North Carolina threaten Georgia's borders.
Georgia has had several widespread outbreaks in the past that required suppression treatments. It is likely that
egg masses attached to incoming cargo brought them from infested areas to Georgia. To date, only European strain moths have been caught in Georgia and they pose a lower threat because the females can't fly. The Asian strain of the same species, however, does have flightcapable females that allows for much greater spread potential and are of higher priority. All moths caught within a 20 mile radius of a port of entry (Atlanta airport or shipping ports at Savannah and Brunswick) are genetically tested to ensure they are not the Asian strain.
While there are currently no known gypsy moth infestations in Georgia, the threat is always present. This is due to the number of visitors and new residents who move to our state from areas of the northeast where the insect is naturalized. Egg masses and live moths can be transported on vehicles, outdoor furniture, firewood or goods such as stone or rock. Through the vigilant use of detection trapping and suppression, gypsy moths are part of a pest success story because they haven't spread as predicted, and can be reasonably controlled where they occur.

Sirex Noctilio Woodwasp A non-native woodwasp, Sirex noctilio (Figure 34), was detected in New York in 2005 and likely entered a port via solid wood packing material in cargo. This federally regulated pest is native to Europe and Asia, and has now been introduced into every continent. It has the potential to kill many species of pines. In Georgia, all pine species could be impacted, including several that have tremendous commercial importance. Loblolly and slash are Georgia's most abundant pine species and are rated as extremely susceptible to this pest. Even minor damage could result in enormous economic losses. This is a large insect (11 inches in length) that is a strong flyer, capable of traveling almost 50 miles in one season. It now infests a sizable portion of New York and has migrated southward into Pennsylvania and northward into Canada.
Figure 34 Part of the insect's life cycle involves creating egg niches and laying eggs in trees. They also inject a symbiotic fungus and toxic mucus into the tree. The larvae feed upon the fungus, but the mucus spreads within the water conductive tissue of the tree and clogs this pathway. When a critical level of this vascular tissue can no longer function, moisture stress occurs in the tree and death soon follows. Furthermore, larvae tunnel through the wood as they feed upon the fungus (not the wood), and these large holes can mechanically disrupt the water conductive tissue.

Threats to Forest Resources
Insects, Diseases and Nonnative Invasive Plants
Sirex has accounted for huge losses of loblolly and slash plantations elsewhere in the world, but it is uncertain what damage will occur if it invades the southern U.S. Several species of native woodwasps are found in the southeastern U.S., including two species within the Sirex genus that do not kill the host trees. In other parts of the world, it has been observed that weakened, stressed stands (such as overstocked plantations) have been more vulnerable to Sirex noctilio than thinned, vigorous stands. Trapping surveys are underway in several southeastern states, including Georgia, but no Sirex noctilio has been detected to date.
A biological control agent (nematode that sterilizes the adults) developed in Australia was shown to successfully suppress outbreaks. This nematode is being tested in New York, and may be introduced in quantity at some point in the future in the United States.

Emerald Ash Borer This insect was first detected in Detroit, Michigan and was thought to have arrived within solid wood-packing material from Asia. It attacks and kills all members of the Fraxinus genera of North America and has now spread through most of the upper midwestern states and as far south as Kentucky and Virginia.
Figure 35
The emerald ash borer (Figure 35) is a buprestid and may have an extended life cycle (two years) in which to develop from egg to adult. This non-native insect appears to have no significant natural enemies in the U.S and is a federally regulated pest. Huge suppression efforts which involved removing infested trees along with some healthy ash trees around the infested ones, have proven unsuccessful. Part of the reason for this is that detecting infested trees is virtually impossible until advanced stages of attack are reached. At this point, some of the insects have developed and emerged. Furthermore, the trapping methods used to determine the presence of this species have not proven effective. Systemic insecticides have been proven effective when applied to individual, high-value trees, but these are relatively short-lived (two years or less), expensive, and repeat applications are necessary.
Although ash is not a tremendously significant species within the rural landscapes of Georgia (FIA indicates about 60,000 acres where ash occurs), the impacts on urban forests may be more significant because green ash is widely used as a street tree.

Asian Longhorned Beetle This Asian species (Figure 36) was first detected in New York City in the 1990s and is believed to have come into the country via solid wood packing material at the port of entry. It attacks 13 different species of deciduous trees: Ash, Birch, Elm, Goldenrain tree, Horsechestnut, Katsura, London Planetree, Maple, Mimosa, Mountain ash, Poplar, and Willow. This federally regulated pest is being fought in three states: Massachusetts, New York, and Ohio, and over 80,000 trees have been killed in these urban forests.
Figure 36
No trapping method has been proven successful in detecting this pest, but vigilant inspections of trees in these areas and prompt tree removals have been successful in minimizing spread and mortality. Several susceptible species are very common throughout Georgia, and improved varieties planted in urban areas would be at high risk for damage if this species were to be introduced.

Cogongrass Cogongrass, Imperata cylindrica, is considered the seventh worst weed in the world. It is listed as a federal noxious weed and is the number one priority invasive plant species in Georgia. Cogongrass (Figure 37) was first introduced into the United States near Grand Bay, Alabama in 1911 via seed packing material in shipping containers from Japan. This grass suppresses and eliminates natural vegetation, thereby significantly reducing tree and plant regeneration, wildlife habitat, forage and ecological diversity.

68
Priority Areas
To identify areas of Georgia where GFC and partners should look first to protect, conserve and enhance Georgia's forest resources, changes in land cover was used as the basis. Land use change due to urbanization and changes in land ownership patterns have impacted not just the types of forest land in Georgia but also the spatial orientation of forest lands. As part of the resource assessment and the priority area identification, changes to the spatial distribution of forest patches throughout the state of Georgia were evaluated. Globally, forest fragmentation has been identified as a key measure of environmental
quality and the ability of the forest to provide critical ecosystem services. These services include protection of water quality and quantity, air quality protection, biodiversity protection and carbon sequestration.
By comparing changes in forest patches over time on land cover maps from Landsat satellite images, areas that still have large contiguous forest available to provide abundant amounts of key ecosystem services were identified. Land cover maps from 1974 to 2008 were used to generate forest fragmentation patterns (Figure 39).

Priority Areas
Forest patches greater than 250 acres make up the core forest areas
(Figure 40). These core areas are at
a size large enough to be managed for critical ecosystem services. The
smaller patches can still be managed for forest activities but have a higher
probability of being impacted by the land use activities that are surrounding them. Thus, as compared to land cover (forest cover), the ability of forests to perform ecosystem services was measured. While forest cover can be maintained in Georgia, fragmentation
and changes to patch sizes as well as exposure to edges and nonforest activities such as development influence how well these patches can provide critical services.

Priority Areas
Georgia's priority resource areas were selected by evaluating percent coverage of core forest areas by using a bounding area that was relatively similar in size across the state. County boundaries and census tracts are highly variable in size and were therefore excluded from the selection. The 12-digit Hydrologic Unit Codes (HUCs) were selected as this unit because they, for the most part, represent a consistent area of approximately 45km2. Percent forest cover was calculated for core patches ranging from 25 to 50 percent forest area coverage of the watersheds (Table 11). Further description of methods and results for determining priority areas is included in Appendix A.

Priority Areas
Blue Ridge The Blue Ridge makes up the mountain area of northeast Georgia. The Chattahoochee National Forest plays an important role in maintaining the large core areas. Additionally, there are numerous public lands maintained by Georgia DNR and GFC as well as multiple lands held in private conservation easements by a number of land trusts. There is considerable pressure from population growth in this region for retirement and second homes. The proximity to metro-Atlanta has made this area a key recreational area in the southeast U.S. In addition to recreational amenities, the area is a critical source of drinking water for the metroAtlanta region. The Blue Ridge is the headwaters of the watersheds of both Lake Allatoona and Lake Lanier. Additional fragmentation of forests in this area has major implications for the condition of the area's water supply.
Ridge and Valley The Ridge and Valley makes up the mountain area of northwest Georgia and is bound by the I-75 corridor between Atlanta and Chattanooga. Forests are found along the slopes and tops of the ridges and there is still extensive agriculture in the valleys. The area is under considerable development pressure because of the corridor that connects Chattanooga with Atlanta, sometimes referred to as "Chattlanta." This corridor is a key industrial area in the state and produces much of the carpet sold in the United States. Major cities such as Dalton and Cartersville are found along this corridor.
Fall Line The Fall Line area is represented by a gradient of three distinct ecoregions: the lower Piedmont, the Fall Line and the upper Coastal Plain. This area has been a key source of natural resources in Georgia. The unique geology of the area, which includes many discontinuities from an ancient shore line to large sand dune areas, provides the recharge zone for the Floridian aquifer.
Large River Bottomlands The geomorphology of the Coastal Plain has allowed for the development of large floodplains and wetlands associated with the river systems. Many of these rivers are blackwater and have unique flora and fauna associated with them. The upland areas between floodplains are a mix of piney flatwoods and wetlands. These areas have been important sources of forest products since colonial times, from naval stores and timber to fiber for paper production. The area also sustains one of the last large populations of black bear in the state of Georgia.
74
Priority Areas
Atlantic Coastal Plain Many of the forests in this area are intensively managed for fiber production. Much of the land was formerly owned by industrial timber companies that have a number of fiber facilities along the coast. With the divestiture of forest lands by large industrial land owners, the ownership patterns have changed in this area. In addition, development pressures coming from coastal counties have led to conversion of these lands from forest products to real estate holdings for potential development. The Atlantic coastal forests have many key wetland areas, both associated with the large river bottomlands as well as many types of isolated wetlands. These play a critical role in maintaining high biodiversity in this region.
East Gulf Coastal Plain The East Gulf Coastal Plain is the most fragmented of the priority areas. The area is the major producer
for commodity crops in Georgia and has a large and shallow aquifer that is used for irrigation of row crops. Forest lands in this region are found along wetland and floodplain corridors. There are large tracts of land that are currently being

Priority Areas
Regional Priority Areas Opportunities to collaborate with neighboring states on common issues include the following:
Alabama-Georgia-Florida Longleaf
Pine Corridor The development of a longleaf pine corridor from Ft. Benning, Georgia to Eglin Air Force Base, Florida via Ft. Rucker, Alabama would protect, conserve and restore longleaf pine ecosystems that are critical habitat for many threatened and endangered species.
Okefenokee National
Wildlife Refuge The recent 564,000 acre Georgia Bay Complex wildfire offers unique opportunities to promote wildfire mitigation efforts in the southeast Georgia and north Florida region. Partners in the area include the wellorganized and nationally known GOAL landowner association, which includes the USFWS Okefenokee National Wildlife Refuge, several forest products companies, private landowners and six rural communities. The Refuge itself is a fire dependent ecosystem. Fuel reduction practices
that benefit this ecosystem include firewise practices, community wildfire preparedness plans and coordinated preparedness measures. Providing education and alternative management options for affected landowners could have a pronounced effect on future management in the area and be used as a national model. Forest management options include the use of prescribed burning and planting of fire-resistant longleaf pine within the buffer area.
Water quality and quantity The Apalachicola-ChattahoocheeFlint River Basin lawsuit may lead to regional plans to protect the flow and quality of rivers from Georgia into Alabama and Florida. Water quality standards and flow continue to be debated in federal and state courts, which may lead to more regulation affecting private landowners. The Alabama-Coosa-Tallapoosa River Basins may also lead to regional plans to protect flow and quality of rivers from Georgia into Alabama. The Savannah River is a subject of continuing negotiations between South Carolina and Georgia regarding water flow and water quality.
Non-native invasive species Three top multi-state efforts to protect forest health include: cogongrass eradication in the south Georgia, north Florida and eastern Alabama areas; hemlock woolly adelgid monitoring and treatment in north Georgia, North Carolina and Tennessee; and laurel wilt monitoring in South Carolina.

Strategic Issues
Water Quality and Quantity
In addition, the effects of agricultural practices, old canals and ditches and poor county road maintenance have resulted in legacy sedimentation, impaired streams and wetland losses.
There are many opportunities for GFC and key organizations to enhance the role forests play in improving Georgia's water quality and quantity.
Potential Agency and
Organization Roles GFC will continue the state
leadership role in BMP development, education, implementation and monitoring.
Through EPA Section 319 and USFS competitive grants, GFC will continue to seek assistance in water quality education. BMP education efforts will be expanded through partnerships with Tree Farm, Trout Unlimited, Riverkeeper and other fisheries and recreation associations. Leveraging more funds with these groups and others is needed to direct more support to excellent but under-funded state programs.
GFC will further expand BMP education by working with the Board of Registration for Foresters to support BMP education and implementation among professional foresters and with non-SFI wood mills to educate their producers about BMPs.
GFC will work with state, federal and local government agencies to provide input and implement regional strategies identified in the Georgia Comprehensive Statewide Water Management Plan.
As NRCS develops Rapid Watershed Assessments (Coosawattee, Ocmul-gee, Upper Oconee, Satilla, Little River and Spring Creek), GFC will help identify forestry and agriculture needs for improvement to the watersheds and gain funding for cost-share assistance to landowners.
GFC will partner with RC&Ds and county road departments to implement Better Back Road BMPs and to identify and rectify stream crossings that are a continuing source of sediment.
GFC and DNR will provide information on high priority streams to commercial and non-profit mitigation bankers to encourage restoration and enhancement of vegetated buffers and provide financial incentives to private landowners to fence livestock out of streams.
GFC and DNR will work with local governments and developers to ensure protection of stream buffers when development plans are considered.
DNR will work with ATV manufacturers to develop and disseminate messages discouraging ATV use in and adjacent to streams.

Water Quality and Quantity
There are 489 stream segments in Georgia that have been determined to be impaired by either sediment (biota) or by a dissolved oxygen deficiency. These stream segments are located in 226 10 digit HUC watersheds across Georgia. In addition, there are 202 12 digit HUC watersheds, mostly in North Georgia, containing one or more public water supply intakes from reservoirs. Figure 44 shows the relationship of the sediment and DO impaired/TMDL watersheds to the water supply reservoir watersheds. Clearly, many of the sediment and DO impaired/TMDL watersheds also contain public water supply intakes, and therefore should be considered critically important watersheds.
Figure 44

Strategic Issues
Urbanization
Issue Description Urban sprawl was ranked the second most important forest resource issue by public stakeholders. GFCfunded studies by the University of Georgia's Natural Resources Spatial Analysis Laboratory (NARSAL) determined that approximately 54 acres of canopy cover were lost in the Atlanta region each day from 1991-2001, while approximately 28 acres of impervious surfaces (e.g. roads, buildings, etc.) were added daily. Updating this information to 2005 showed a slight decrease in canopy loss but impervious surface additions increased to approximately 55 acres daily.
In a similar statewide analysis, NARSAL determined that from 2001- 2005, Georgia's canopy cover declined by a total of 398,330 acres, or 273 acres per day. Although canopy loss in rural areas often reflects ongoing forestry activities, in urban areas it often indicates development. Accordingly, impervious surfaces increased by about 154,134 acres, or 106 acres per day.
These changes effectively and permanently remove this acreage from forest cover. The effects of forest cover loss on water quality and quantity are huge. Trees act as natural water filters and help significantly slow the movement of storm water, which lowers total runoff volume, soil erosion and flooding. Infiltration rates for forested areas are 10 to 15 times greater than for equivalent areas of turf and grass. During a heavy rain, a healthy forest can absorb as much as 20,000 gallons of water in an hour. Many municipalities are now charging businesses and homeowners a "storm water utility"
fee based on the amount of impervious surface at their location.
Air quality and local climate are also negatively affected by loss of forest cover. In exchange for providing oxygen, trees absorb carbon dioxide produced from the combustion of various fuels. Trees remove or trap lung-damaging dust, ash, pollen and smoke from the air, in addition to providing shade for people and conserving energy. In the Atlanta metro area, trees removed 19 million pounds of pollutants, valued at $47 million in 1996. Tree cover as it existed in 1974 would have removed 30 million pounds of pollutants, valued at $75.5 million (American Forests 2001).
Loss of forest cover affects the health of communities. Trees enhance community economic stability by attracting businesses and tourists. Studies have found a correlation between community forests and the average amount of physical activity exerted by neighborhood residents. People are more inclined to get outdoors and exercise when their surroundings are greener. Logically, greater physical activity leads to fewer cases of obesity, which in turn may help reduce other health problems such as heart disease and diabetes.
Urbanization increases apprehension about fire. Air quality has become a major concern in Georgia, and prescribed fire has been targeted as one of many sources of harmful emissions. Drift smoke from prescribed fire and wildfires concerns urban dwellers. An important challenge is to help Georgians understand the life sustaining properties of healthy forests, and the natural role that fire plays in ecosystems.
83
Urban sprawl places lives and property at risk from wildfire and reduces options for proper fire management. More than half of Georgia homes are located in the Wildland Urban Interface. The greatest fire management challenge for forestry professionals is to ensure public safety by providing fire prevention services in the form of prescribed fire as well as wildfire suppression. The sustainability of Georgia's forest is dependent on attention to both prescribed fire and wildfire suppression.
Forest conservation is a special priority north of the Fall Line, along the coast and in counties with the highest growth projections. Key lands for acquisition should be identified and prioritized in these rapidly-growing areas. According to a telephone survey conducted by The Statewide Comprehensive Outdoor Recreation Plan (SCORP), 88 percent of Georgians support public funding for investment in outdoor recreation.
As Georgia becomes more urbanized, it will become more challenging to sustain a connection between urban populations and our natural resources. Our forest land, parks and nature-based recreation will provide critically important connections to the environment and promote a conservation ethic.
Additionally, our schools should have access to natural areas for education. Schools must provide balanced interpretation, education and outdoor recreation programs to promote healthy lifestyles and knowledge of our natural resources.

Potential Agency and
Organization Roles GFC will initiate updated tree
canopy loss and impervious surface studies and help build local capacity to manage tree canopy. GFC will identify areas of opportunity within community watersheds to connect forest patches to improve the water and air quality function of forest canopy, identify appropriate mechanisms, and facilitate discussions to link patches with landowners, local governments and conservation-minded nonprofit organizations. The Georgia Urban Forest Council and GFC will utilize grant and corporate funds to plant trees in communities to assist in job creation, help stimulate the economy and restore ecosystems impacted by growth and urbanization. GFC, DNR, USFS and the USFWS will provide information and education opportunities concerning wildfire management challenges and the benefits of prescribed fire. GFC and DNR will promote forest canopy benefits in riparian buffers and demonstrate impacts of canopy loss in interface watersheds. GFC will continue to promote the Changing Roles training within GFC and with other state partners.
The Georgia Forestry Association,
GFC and University of Georgia Warnell School of Forestry and Natural Resources will expand the Project Learning Tree program to educate youth on forest conservation.
Issue-Specific Priority Areas Areas of focus to address the urbanization issue include metropolitan Atlanta, north Georgia and the coast. These areas have the greatest population density as well as population growth. Federal and corporate grant funds will be used to focus on high-profile projects in these areas. Potential projects include establishment of model stormwater management demonstration sites and ecosystem restoration. Watershed planning work in north Georgia's Blue Ridge and Ridge and Valley priority areas will target opportunities to enhance the water and air quality function of forest canopy.

Bottomland forests and associated
cypress-gum swamps are important
habitats for a variety of wildlife groups,
including neotropical migratory birds,
bats, waterfowl, wild turkey, game
mammals, reptiles and amphibians.
This general habitat type includes
linear or small-patch communities
such as canebrakes, floodplain pools,
riparian forests and hardwood and
pine-dominated hammocks. Though
present in every region of the state,
bottomland hardwood forests and
cypress-gum swamps are most
prevalent in the Coastal Plain (Figure

and contiguous bottomland forests
is important for conservation of
Georgia's wildlife diversity. In
particular, old-growth canopy trees,
snags, large woody debris and diverse
midstory and understory vegetation
are important elements to maintain
in these forests.

Protection of headwater streams
Headwater streams are found in the
uppermost reaches of watersheds
and may have flowing water for only
a portion of the year. They account
for the majority of stream miles in a
given watershed, and are important
for a wide variety of species, including
several species of conservation con-
cern (Meyer et al. 2003; Georgia De-
partment of Natural Resources 2005).
Headwater streams are also important
for maintenance of water quality and
aquatic wildlife habitat in the higher-
order perennial streams which they
feed (Ohio Environmental Protection
Agency 2002).
Intermittent/ephemeral streams and
associated seepage zones are often
overlooked when streams and wet-
lands are mapped. In addition, they
have received less research emphasis
than perennial streams (Meyer et al.
2003). In areas where development
pressures are high or agricultural uses
are prevalent, many of these habitats
may be adversely affected by land-dis-
turbing activities or piping of streams
(DeMeo et al. 2005). While important
in every watershed in the state, pro-
tection of headwater streams is most
critical in those watersheds that have
been identified as high priority for
conservation of aquatic biodiversity

Those landowners who wish to develop projects may use the registry as a marketing tool, and registry staff members actively pursue market opportunities for registered projects. There are currently a number of landowners participating in carbon offset projects, mainly through the Chicago Climate Exchange (CCX).
In addition to the carbon sequestration benefit, trees remove or trap lungdamaging dust, ash, pollen and other air pollutants. By reducing air pollution, they save money in pollution mitigation efforts and health care costs (Georgia Urban Forest Council 2005b). To sustain air quality, communities must set goals to minimize the loss of trees while maximizing their benefits.

Air Quality Carbon Sequestration
Potential Agency and
Organization Roles GFC staff worked with the
Southern Group of State Foresters (SGSF) to develop a guiding principles paper that focuses on carbon offsets from a southeast regional perspective and will work to promote the principles.
The GFC and Oglethorpe Power Corporation are partnering on a reforestation project in a state forest. This project will result in carbon offsets produced from the tree planting on sites devastated by the 2007 wildfires in south Georgia.
GFC staff members continue to monitor developments on a national scale concerning climate change legislation so that Georgia's landowners will be well positioned to participate in carbon markets.
GFC will identify air quality benefits of community forests related to public health.
The Georgia Urban Forest Council and GFC will utilize grant and corporate funds to plant trees in communities.
Issue-Specific Priority Areas Focus areas for reducing greenhouse gases by increasing carbon sequestration are in the Blue Ridge, Ridge and Valley and East Gulf Coastal Plain. Urban priority areas will be targeted for com- munity tree planting projects.

Fire Management
Issue Description One of the founding missions of the Georgia Forestry Commission was the protection of forest resources from wildfire. Today, about two-thirds of Georgia's land area, or 24.8 million acres of forest land, is protected by the Georgia Forestry Commission. Timber is the highest valued crop in Georgia, with a total economic impact of $28.7 billion. Georgia averages approximately 5,600 wildfires per year that burn 46,000 acres. In addition to that annual loss of or damage to forest land, a major threat is posed by the potential loss of life and property. Georgia currently loses approximately 110 homes valued at $4.2 million and 185 outbuildings valued at $1.3 million to wildfire each year. The GFC Fire Management program saves approximately 3200 structures (homes and outbuildings) valued at $503 million annually through direct wildfire suppression efforts. Urbanization, increasing levels of forest fuels and restrictions that reduce prescribed burning are escalating forest wildfire threats.
Mitigating the effects of wildfires is an integral part of GFC's Fire Management program. Suppression alone cannot limit the effects of wildfire, because fire is a volatile force of nature. Fuel reduction programs are essential to providing protection from wildfires. Pressure from urbanization, air quality controls and public acceptance has placed challenges on the GFC to provide acceptable mitigation programs. Limitations on GFC's ability to administer low cost applications, such as prescribed burning, hinder the ability to provide affordable protection for Georgia's citizens.
The recent Southern Wildfire Risk Assessment determined that 25 percent
of Georgia, or about nine million acres, is designated as Wildland Urban Interface. The SWRA also determined that 5,000 of Georgia's communities are ranked as "high" or "very high" for wildland fire risk. Mitigation program limitations have compelled the Fire Management program to provide more public education about the risk from wildfires and the need for more fire prevention. Most fire causes can be traced to human involvement. Preventing man-made fires from starting is a continuing challenge and GFC is dedicated to finding programs that help reduce this cause of fire. All fires are not preventable, so we must also ensure that we have good wildfire protection programs in place when fires do occur. Wildfire protection can be addressed at the county level, at the community level and for the individual homeowner.
As the U.S. economy has faltered over the past several years, GFC's workforce has diminished. It has been necessary to develop several partnerships with state and federal agencies, as well as land management organizations. GFC continues to be the lead agency in wildland fire, but depends on its many partners to help accomplish the overall mission. Partnerships are also used to ensure the smooth transmission of programs such as wildland fire suppression, prescribed burning and air quality. In order to maintain superior performance and protection, it is necessary for these partnerships to grow and expand.
A strategy must be implemented to affect the condition of the landscape, increase safeguarding of communities from wildfire and prepare fire managers to address conditions caused by changing weather phenomena.

Fire Management
Potential Agency and
Organization Roles
The most important mission of the Fire Management program is fire suppression. GFC is mandated by the state of Georgia to suppress wildfires. However, the downturn in the economy and reductions in state budgets have strained personnel and resources. To continue the protection of lives, property and forests, GFC will:
Increase GFC Forest Ranger training as experienced work force retirements increase.
Provide basic training on wildland
firefighting to structural firefighters through the Georgia Fire Academy. Increase firefighting equipment refurbishing options. Incorporate technological advances in communications and weather predictive systems. Participate in the Firefighter Program to acquire better quality equipment. Administer Volunteer Fire Assistance grants for small fire departments to help with purchase of training and equipment and the Helping Hands program to provide for low cost personal protective gear to fire departments and other fire suppression cooperators. Issue authorizations for outdoor burning through the GFC Permit System. Provide pre-suppression firebreak plowing and burning assistance to landowners.
Conduct forest fuels reduction burning assistance to landowners.
Provide National Incident Manage-
ment System training for Georgia. Promote prescribed burning and
certify burn practitioners through the Certified Prescribed Fire Manager program. Provide local county governments with a comprehensive Community Wildfire Protection Plan (CWPP). Using the Firewise USA program, introduce Firewise concepts to atrisk homeowners. Continue to develop and implement innovative Fire Prevention programs. Continue the Redesign Grant.
Issue-Specific Priority Areas To identify Fire Management programspecific priority areas, the GFC utilized the Southern Wildfire Risk Assessment (SWRA). Maps of forest fuels, historical wildfire occurrence, values at risk from wildfires and communities at risk were used to develop the wildfire susceptibility index (WFSI) and levels of concern (LOC), which measure wildfire risk. These SWRA products are the main tools used in assigning priority to GFC Fire Management programs including CWPPs, fire prevention and mitigation efforts.
Of Georgia's 12,000 communities, more than 5,000 are rated "high" or "very high" for wildland fire risk. Because the greatest risks occur in WUI areas and fall on the edges of Georgia's priority areas, the SWRA priority areas are set within each county.
An overlay of the statewide fire occurrence map with Georgia's priority areas (Figure 53 on the following page) identifies the Blue Ridge, Ridge and Valley and the Atlantic Coastal Plain as priority areas on which to focus fire suppression efforts.
The Community Protection Grant identifies priority areas for prescribed burning near USFS property. Overlays of this data on Georgia's priority areas identify the Blue Ridge, Ridge and Valley and the Fall Line as primary targets for prescribed burning. The Okefenokee (GOAL) grant targets areas in and around the Okefenokee Swamp within the Atlantic Coastal Plain area. Wildlife management programs such as the Bobwhite Quail Initiative have identified the East Gulf Coastal Plain and Large River Bottomlands as priority areas for prescribed burning in longleaf pine ecosystems.

Fragmentation and Parcelization
Issue Description Thefutureof Georgia'sforestsisimperiled by increasing forest fragmentation and parcelization. Parcelization results when the number of forest landowners increases, but the forest land is held in smaller parcels, measured at 50 acres or less (Wear and Greis 2002). Though parcelization may not result in forest canopy loss, in many cases resources on the tract become unavailable to markets.
Forest fragmentation is the division of contiguous forest stands into smaller, isolated pieces or less contiguous tracts due to development, conversion to agriculture, the divestiture of forest land by the forest industry and other human activities.
Both fragmentation and parcelization may disrupt wildlife corridors and migration routes of many wildlife species. Those species requiring large, undisturbed expanses may decline. They may also cause adverse changes in water quality and quantity and impede the management of fire and forest pests. Fragmentation and parcelization result in less efficient management units, which contribute to cost increases and resource management difficulties.
to convert their forest lands to other uses. Urbanization pressures, taxation and mass divestitures of forest industry land are leading concerns.
A major urbanization factor is leapfrog development sprawl, a discontinuous pattern of urbanization with patches of developed lands that are widely separated from each other and from the boundaries of recognized urbanized areas. Such sprawl isolates forest patches, drives up the highest and best use value and ensures their conversion to development.
Several taxation issues affect forest land ownership and the forest industry in Georgia. However, none is more critical to the future of Georgia's forests than property taxes. Georgia's ad valorem tax system was created during a time when the wealth and profits of the state came out of the production of the land when cotton was still king in the 1800s. As times have changed and Georgia has become increasingly urban, the tax structure has remained the same. As a result, forest land valuations for tax purposes are inconsistent across Georgia and "highest and best use" land valuation threatens forest sustainability.
Fragmentation has been identified as a Non-industrial private landowners

Strategic Issues
Fragmentation and Parcelization
Traditional forest products companies have also been impacted by highest and best use tax assessment resulting in divestitures to timber investment management organizations (TIMOs) and real estate investment trusts (REITS). One result of greater TIMO and REIT involvement is a more rapid turnover in forest ownership and an increased potential for subsequent parcelization into smaller-sized properties (Wear et al. 2007).
In addition, landowners must pay severance taxes on timber. For many, owning forests and timber land has become a poor business decision. Studies show that for every $1.00 in ad valorem tax generated by Georgia's timber lands, those same lands receive less than $0.50 return in services.
In 1991, the General Assembly passed the Conservation Use Valuation Assessment Act (CUVA). It provides for a reduction in property tax assessments and is available only to private individuals who own forest land not exceeding 2,000 acres. Lands belonging to forest industry companies are not eligible. As a result, many companies divested their lands. CUVA properties are assessed according to soil type, productivity and a reduced fair market value factor. Landowners are required to place their property in 10-year covenants, severely restricting the use of the property. If a covenant is breached, stiff penalties must be paid. Each county tax assessor's office administers the program independently, so application requirements may vary among counties. Generally, a minimum of 10 acres is required for enrollment, but some counties have recently increased the minimum acreage to 25 acres. No more than 2,000 acres can be enrolled in CUVA by any one nonindustrial, private landowner.
Because of the mass divestitures of forest industry land, in November 2008, Georgians overwhelmingly voted for a Constitutional Amendment that provides relief for property taxation of Georgia's forests over 2,000 acres. Through the Forest Land Protection Act (FLPA), large tracts of privately or corporately owned forest lands may be eligible for reduced property tax.
LandownerscanapplyforFLPAvaluation of their property if they meet eligibility requirements and sign a conservation agreement to keep the land in a qualified use for 15 years. Landowners receive a reduced ad valorem tax rate for property enrolled in FLPA. Eligible tracts must be used for subsistence or commercial production of trees, timber or other wood and wood fiber products; and the value of any residences on the property are excluded. Properties must be a minimum of 200 acres, but unlike CUVA, there is no maximum acreage cap.
Forest land designated for conservation use may include land that has been certified as environmentally sensitive property by the Department of Natural Resources. It may also be property that is kept in accordance with a recognized sustainable forestry certification program. The property may have compatible secondary uses such as the promotion, preservation or management of wildlife habitat, carbon sequestration or mitigation and conservation banking that results in the restoration or conservation of wetlands and other natural resources.
Opportunities are to provide landowners with incentives to retain manageable tracts of forest land that can compete with the financial returns of converting or selling forest land for other purposes. Some of these
incentives could be in tax relief and in the development and support of markets to increase the financial investment value of forest resources. Maintaining incentives and smart public policy to allow lands to remain in forest cover will provide both environmental and economic benefits for Georgians in the future.
Georgia's forests are a valuable natural resource and economic engine for our state. Forest landowners should be given every opportunity to hold their property for the benefits of forest sustainability and the security and enjoyment of future generations.
Potential Agency/Organization Roles There is still much that needs to be done to address the inequity that exists across Georgia in the application of ad valorem taxes:
GFC will continue to educate landowners about CUVA and FLPA opportunities and educate local tax assessors about how to adequately evaluate the properties enrolled in these programs.
GFC will work with the Department of Revenue as it reviews and enhances statewide regulations.
GFA will use its advocacy role to educate state legislators about the need for ad valorem tax reform in the state and about inequitable tax impacts on forest landowners and the forest industry.
Issue-Specific Priority Areas The large forest land base and economic dependence on forestry makes south Georgia counties a priority. Many rural counties throughout south Georgia rely almost entirely on ad valorem taxes for their budgets.

Primary Data Sources Dr. Elizabeth Kramer of the University of Georgia College of Agriculture and Environmental Sciences developed the geospatial data layers for use in priority resource area identification. The following is Dr. Kramer's report on the data sources, methods and results of the priority area identification process.
Introduction Land use change due to urbanization and changes in land ownership patterns have impacted not just the types of forest land in Georgia but
also the spatial orientation of forest lands. As part of the resource assessment and the priority area identification, changes to the spatial distribution of forest patches throughout the state of Georgia were evaluated. Globally, forest fragmentation has been identified as a key measure of environmental quality and representative of providing critical ecosystem services. These services include protection of water quality and quantity, air quality protection, biodiversity protection and carbon sequestration.
Over time, many different metrics have been developed to assess the spatial distribution of forests extent and intactness of forest areas. Numerous reviews and tools are available to assess patch level metrics; these tools include measures of internal and external fragmentation, changes in patch areas and numbers
as well as changes in shape such as perimeter measures (Vogt et al. 2007). There are limits to the use of these tools when working in areas with large numbers of small patches. Newer techniques allow for large area pixel-level mapping to identify patches and landscape morphology (Vogt et al. 2007 and Soille 2003). These techniques use methods in morphological image processing to map edge types and produce metrics of patch dynamics. By comparing changes in forest patches, over time areas that still have large contiguous forest available to provide abundant amounts of key ecosystem services can be prioritized.
Methods
Land Cover Data Data from the Georgia Land Use Trends Program (GLUT) was used for the analysis. GLUT is a series of land cover maps produced from Landsat satellite images. The earlier maps 1974 and 1985 were derived from Landsat MSS data the rest of the maps (1991, 1998, 2001, 2005 and 2008) were derived from higher resolution Landsat TM images. The GLUT program tracks 13 land cover classes over time: 1) mud/sand/beaches; 2) open water; 3) Low Intensity Urban; 4) High Intensity Urban; 5) Clearcut/ Sparse Vegetation; 6) Mines/Quarries/ Outcrops; 7) Deciduous Forest; 8) Evergreen Forest; 9) Mixed Forest; 10) Agriculture; 11) Forested Wetlands; 12) Brackish Wetlands/Marshes; and 13) Freshwater Emergent Wetlands. All classes are reported at a 60 meter pixel resolution. For this analysis, the forest fragmentation results for the 2008 land cover map product was the focus.

The Landscape Fragmentation Tool
(LFT), developed by the Center for
Land Use Education and Research
(CLEAR) at the University of Con-
necticut, was used to analyze forest
fragmentation in Georgia (http://
clear.uconn.edu/projects/land-
scape/forestfrag/index.htm). The
GLUT land cover is reclassified
into three classes: forest, non-forest
and water. For this study, an edge-
width of 100 meters was used. The
edge width distance is defined as the
width over which non-forest land
covers can degrade the function of
forest land cover. This edge-width
helps to define the output of for-
est types core, perforated, edge and

eas are large enough to be managed
for critical ecosystem services. The
smaller patches can still be managed for forest activities, but have a higher
probability of being impacted by the
land use activities surrounding them. Thus, as compared to land cover
(forest cover), the ability of forests
to perform ecosystem services was
measured. Forest cover in Georgia
can be maintained, but fragmen-
tation, changes to patch sizes and
exposure to edges and non-forest
activities such as development will
influence how well these patches can
provide critical services.

Integration of Other Plans
and Assessments
Wildlife Probably the greatest tool available for guiding efforts to sustain overall forest wildlife in Georgia is the "State Wildlife Action Plan" (SWAP). This document, entitled A Comprehensive Wildlife Conservation Strategy for Georgia, was completed by the Wildlife Resources Division of DNR in 2005 with the help of many private and public stakeholders.
The SWAP focuses on those species and habitats believed to be most in need of conservation attention because of population declines and continuing threats. It lists 296 high priority animal species and 323 plants, along with a number of forest and non-forest habitat types.
It addresses the extent and condition of essential habitat types, as well as habitat problems and conservation opportunities. It also addresses research, surveys, monitoring and habitat restoration needs, and provides an evaluation of existing conservation policies and programs. In addition, the SWAPoutlinespartnershipopportunities and prioritizes the implementation of specific conservation actions.
Of a list of 25 "problem categories" for high priority species and habitats, developed within the strategy and used in an overall assessment, four have direct ties to forest management activities: alteredfireregimes,conversionof natural forests to agricultural and silvicultural uses, forestry practices not meeting the standards of Best Management Practices and invasive/alien species. There are opportunities to address these problems and enhance sustainability.
Strategies from the State Wildlife Action Plan were incorporated into the Georgia Statewide Assessment of Forest Resources.
Water The Georgia Comprehensive Statewide Water Management Plan of January, 2008, prepared by the Georgia Environmental Protection Division (Georgia DNR 2008) in cooperation with recommendations from the Water Council, stated that of all its natural resources, none is more important to the future of Georgia than water. Meeting future water challenges will require a more proactive and comprehensive approach. The plan can be viewed: http://www.georgiawaterplanning. org/pages/more_information/state_ water_plan.php.
During the development of the Georgia Statewide Assessment of Forest Resources, the Water Management Plan was used to identify public water supply watersheds and impaired streams on which to focus monitoring efforts.
The Georgia Comprehensive Statewide Water Management Plan was developed with input provided by basin advisory committees, a statewide advisory committee and technical advisory committees. Potential water policies and management practices relating to regional concerns were discussed at numerous town hall meetings held across the state. Hundreds of individuals representing agriculture, forestry and business interests, local governments, water authorities, nonprofit agencies, trade associations and others provided input. It was recognized that water resources and water needs vary widely by region, and future growth and development will occur differently in each region. What emerged was a
blueprint that, when executed, will guide future decisions about water management across the state. It provides a flexible framework for regional water planning and allows for these regional differences while also providing statewide policies and management practices to support regional planning. The plan hinges on regional forecasts of future needs and will identify the management practices to be implemented, following state policy and guidance, to ensure that the anticipated demands can be met. When developed and approved, the state must partner with the various users in the region to implement the plans. This plan will guide the stewardship of Georgia's precious water resources to ensure that they continue to support growth and prosperity statewide while maintaining healthy natural systems. The plan addresses the following elements: An integrated water policy Water quantity and water quality
policies A water resource assessment Establishing water quantity and water
quality management practices Water demand and water return
management practices A water supply management policy Enhanced water quality standards
and monitoring practices Enhanced pollution management
practices Regional water planning
Going forward, GFC will provide forestry information to the Regional Councils to guide future water quality and quantity policy issues.

Forest Stewardship Georgia's Forest Stewardship Plan was an important resource used by the State Forest Stewardship Coordinating Committee during the development of the Statewide Assessment of Forest Resources. The committee coordinates the Forest Stewardship Program and provides advice and recommendations to the State Forester concerning implementation of the Forest Legacy Program. The assistance and recommendations provided by the group during the development of the Assessment ensured a product focused on the interrelatedness of the multiple benefits and needs of Georgia's forests.
Fire Management The Prescribed Fire In Georgia: A Strategic Plan 2008-2020, was developed in 2008 by 40 professionals from Georgia and Florida with over 500 years of combined experience. The three-day "Fire Summit" at the Tall Timbers Research Station and Land Conservancy produced a strategic plan with goals and objectives that reflect the highest priorities based on the current and projected status for prescribed burning. Goals and objectives from this plan were incorporated into the Georgia Statewide Assessment of Forest Resources. To view the document, visit http:// www.gatrees.org/ForestFire/documents/PrescribedFireinGAStrategicPlan2008-20.pdf.
The Southern Wildfire Risk Assessment was used to identify the potential for serious wildfires within Georgia and to provide information that will help prioritize areas where mitigation options may be desirable.
The models utilized ensure that the assessment results are consistent, comparable and repeatable using the Southern Fire Risk Assessment System (SFRAS) software application.
The published results utilize data layers including maps of forest fuels, historical wildfire occurrence, values at risk from wildfires and communities at risk to develop the two main product outputs. These are wildfire susceptibility index (WFSI) and levels of concern (LOC) for damage from wildfires. The WFSI integrates the probability of an acre igniting and the expected final fire size based on the rate of spread in four weather percentile categories into a single measure of wildland fire susceptibility. The WFSI is used for determining the probability of an acre burning. This index is used to identify areas that have the highest probability of a fire ignition during periods of high fire danger. WFSI and Fire Effects Index were used to calculate the LOC. With this measure, level of risk at any location across the state can be identified. These SWRA products are the primary tools used in assigning priority to GFC Fire Management programs including CWPPs, fire prevention and mitigation efforts.
Forest Health The Georgia Department of Natural Resources headed an effort in 2008 and 2009 to bring many stakeholders together to formulate The Georgia Invasive Species Strategy. The Committee identified needs and existing efforts for response to or detection of invasive species problems within the state. As part of this process, the committee identified 51 invasive or
potentially invasive plant species, 107 animal species and 30 disease-causing organisms. Based on this information, the committee set goals and objectives and proposed strategies for action. The goal of this effort is to prevent and control the introduction of invasive species into Georgia and minimize the further spread and impacts of existing invasive species populations on native species, environmental quality, human health and the economy. The Strategy endeavors to do this through eight objectives: 1. Coordinate local, state, regional,
federal and international activities and programs pertaining to invasive species in Georgia. 2. Control and manage the introduction and spread of invasive species in Georgia through education and outreach. 3. Prevent the establishment of invasive species populations in Georgia through early detection and rapid response programs. 4. Control or eradicate established invasive species in Georgia through cooperative management activities designed to minimize impacts to non-target species. 5. Monitor the distribution and impacts of invasive species in Georgia to determine management priorities. 6. Identify and implement needed research on impacts and control of invasive species in Georgia. 7. Prevent the introduction and spread of invasive species in Georgia through legislative and regulatory efforts. 8. Secure adequate long-term funding for invasive species programs in Georgia.

Appendix
There are 40 actions in the Strategy to address these objectives. Some of the first actions are anticipated to be the development of new educational materials relating to invasive species, funding of a statewide invasive species coordinator and development of a rapid response plan to control or eradicate priority invasive species populations and coordinate responses with full partner participation.
The purpose of the Georgia Invasive Species Strategy is to coordinate support for all state invasive species efforts through collaboration and full communication among agencies and organizations. Not only does
such a planning effort improve the effectiveness of field actions, it can also increase funding opportunities for the proposed actions. Cooperation among the committee members (drawn from 15 state entities, seven federal agencies and nine non-governmental organizations) was central
to the development of the strategy, and will be critical to its execution.
