Forest Inventory & Analysis
What FIA Is
The South Carolina Forestry Commission’s Forest Inventory and Analysis (FIA) program conducts an ongoing forest “census” that is used to describe the extent, type, size and overall health of our forests. The FIA program has been in continuous operation since the 1930s. An initiative of the US Forest Service, the nationwide data collection program is now conducted primarily by state forestry agencies in the South.
In South Carolina, three 2-person Forestry Commission crews measure 2,719 permanent forested plots over a five-year period. Each crew is assigned to one of the three agency regions with headquarters at Florence, Columbia and Newberry.
The FIA crews are led by a program manager located at the Columbia headquarters. The permanent plots are located on both public and private forestlands. Each plot is 1/6th of an acre and represents 6,000 acres of South Carolina forestland. Over 100 individual attributes are measured on each plot in order to describe the tree species, size and health. These data provide accurate information about the sustainability of our forested resource in South Carolina.
