The Georgia Forestry Commission (GFC), in coordination with the U.S. Forest Service, conducts ongoing forest inventory measurements throughout Georgia. The purpose is to periodically gather land and forest resource data from a series of permanent sample plots in order to assess current forest resource status and trends in Georgia.
What is Forest Inventory Analysis (FIA) data?
FIA data is a set of measurements that detail Georgia’s current forest resources. GFC staff use this information to provide guidance and assistance to the existing forest industry and prospective industries in sustainable utilization of Georgia’s renewable forest resources. FIA Data includes:
- species composition and diversity
- live wood and biomass volumes
- wood growth and removals
- forest health
- insect and disease impact
- past natural and human-caused disturbances
- land use changes
- forestland types
- age classes
What is the benefit of the data?
We collect the data so that we can assess trends and track current forest resource status. FIA data is valuable as a historic record and it provides documentation of current conditions and trends affecting Georgia’s forest resource. It also helps with decisions about timber supply and wood production.
How is the data collected?
Twelve GFC foresters work full time to collect FIA data. Data is periodically gathered from permanent randomly-selected sample plots. When selecting the plots, we do not consider current land use, ownership, location, or land use changes. Data is gathered from approximately one plot per 6,000 acres of forested land. Data queries for small areas should not be done. A good rule of thumb for Georgia is to examine a geographic area that includes at least 20 counties, or within a 50 mile radius of a given point.
How is the data used?
Municipal leaders and government agencies use FIA data to make decisions on development, commerce, wildlife and much more. Nationally, collected data is electronically compiled and forwarded to the U.S. Forest Service FIA program office in Knoxville, Tennessee. Based on a five-year rolling average for data parameters, the information is compiled into county, regional, and state summaries and is available through the U.S. Forest Service.
A special thanks to the USFS, our partner in conservation and protection, for providing funding.

|2016 FIA Data – Forest Inventory and Analysis Program: Trends for Georgia’s Forest Land|
Collected information for the Forest Inventory and Analysis (FIA) Program, a cooperative program between the U.S. Forest Service and the states to provide estimates of the condition of the forest and forest trend data.
|FIA Statistics Report for Georgia (1997)|
This report highlights the principal findings of the seventh forest survey of Georgia. Field work began in November 1995 and was completed in April 1998. Six previous surveys, completed in 1936, 1953, 1961, 1972, 1982, and 1989 provide statistics for measuring changes and trends over the previous 62 years.
|Forest Inventory and Analysis (FIA) National Program|
As the Nation’s continuous forest census, the FIA program projects how forests are likely to appear 10 to 50 years from now. This enables us to evaluate whether current forest management practices are sustainable in the long run and to assess whether current policies will allow the next generation to enjoy America’s forests as we do today.

|Georgia Harvest and Utilization Study (2004)|
FIA conducts logging utilization studies to relate TPO to inventory volume. This is done by visiting a cross-section of logging operations in a state to characterize the sites logged, trees cut, products taken, and residues left behind. This resource bulletin describes the principal findings of a harvest and utilization study conducted during the sixth and seventh inventories of Georgia’s forest resources.
|Georgia Harvest and Utilization Study (2009)|
FIA conducts logging utilization studies to relate TPO to inventory volume. This is done by visiting a cross-section of logging operations in a state to characterize the sites logged, trees cut, products taken, and residues left behind.This resource bulletin describes the principal findings of a harvest and utilization study conducted during the ninth inventory of Georgia’s forest resources.
|Georgia Pulpwood Production Fact Sheet (2009)|
This fact sheet is adapted from Southern Pulpwood Production, 2009. The full report presents the findings of a 100 percent canvass of pulpmills that drew roundwood or wood residues from the 13 Southern States during 2009.
