DescriptionThe Forest Inventory and Analysis (FIA) program of the U.S. Forest Service (USFS) measures a spatially distributed base grid of forest inventory plots across the United States. The sampling intensity of plots may be increased in some regions when warranted by specific inventory objectives. Several intensification methods have been developed within FIA and USFS National Forest Systems regions; however, a national standard routine for plot intensification does not exist. This report examines eight candidate intensification methods by a developed set of evaluation criteria, and based on those results proposes that FIA adopt the GRID method as its national plot intensification procedure. It is also suggested that the current version of the GRID method be updated by converting it to an ESRI ArcGIS add-in tool.
