Abstract
The Forest Inventory and Analysis (FIA) program produces area estimates of forest land use within three subcategories: timberland, reserved forest land, and other forest land. Mapping these subcategories of forest land requires the ability to spatially distinguish productive from unproductive land, and reserved from nonreserved land. FIA field data were spatially interpolated to produce a geospatial data set of forest site productivity. A geospatial data set of lands reserved from wood products utilization was delineated from the Protected Areas Database. The combination of these two geospatial data sets, along with a geospatial data set of forest land cover, provided an initial approach for mapping three subcategories of forest land use. Compared with inventory estimates, the mapping approach led to similar estimates of forest land area, overestimates of timberland and reserved forest land, and an underestimate of other forest land. Additional work is needed to improve geospatial data sets of forest site productivity.
