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) and Southern Research Station (SRS), Forest Inventory and Analysis (FIA) regions (39 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 (http://apps.fs.fed.us/Evalidator/evalidator.jsp) for the following estimates:- Net merchantable bole volume of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2006
- Net merchantable bole volume of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2011
- Net merchantable bole volume of live trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2016
- Average annual net growth of merchantable bole volume of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2016
- Average annual mortality of merchantable bole volume of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2016
- Average annual removals of merchantable bole volume of trees (at least 5 inches d.b.h./d.r.c.), in cubic feet, on forest land 2016
- Year of hemlock woolly adelgid invasion
