Description: This feature service is based on ESRI's USA Counties layer (available here) that has been subset to the USDA Forest Service, Northern Research Station (NRS), Forest Inventory and Analysis (FIA) region (24 states). Features and attributes of ESRI's layer have been adapted to match attributes within the FIA database (FIADB) and features have been generalized by removing vertices to enhance performance. This layer has been attributed with outputs from FIA's EVALIDator tool (https://apps.fs.usda.gov/fiadb-api/evalidator) for the following estimates:
Area of forest land, in thousands of acres
Area of timber land, in thousands of acres
Net volume of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land
Average annual net growth of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land
Average annual removals of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land
Average annual mortality of trees (at least 5 inches d.b.h./d.r.c.), in trees, on forest land
Aboveground dry weight of live trees (at least 1 inch d.b.h./d.r.c), in short tons, on forest land
Aboveground carbon in live trees
Total carbon, in short tons, on forest land
Net volume of growing-stock trees (at least 5 inches d.b.h.), in cubic feet, on timberland
Net volume of sawtimber trees, in board feet (International 1/4-inch rule), on timberland
Ratios have also been calculated for area of forest land to total land area and area of timber land to total land area.
States without available data are omitted and will be updated as data become available.
Additional data descriptions are available in the most recent FIADB User Manual, available here.
