Abstract

The ecological state of US Drylands is unknown. This research is developing procedures to determine the impact of the ecological footprint of grazing livestock on the productive capacity of US Drylands. A pilot geodatabase was developed for the state of Texas that includes 2002 data for county boundaries, net primary productivity (NPP) derived from the Moderate Resolution Infrared Spectroradiometer (MODIS), USDA's National Agricultural Statistics Service's (NASS) county-level data on livestock type inventories, the 2001 National Land Cover, and 50-year gridded mean annual precipitation (MAP) and mean annual potential evapotranspiration (MAPET) data.
