The Starkey Project, a large-scale, multidisciplinary research venture, began in 1987 in the Starkey Experimental Forest and Range in northeast Oregon. Researchers are studying effects of forest management on interactions and habitat use of mule deer (Odocoileus hemionus hemionus), elk (Cervus elaphus nelsoni), and cattle. A habitat database was compiled, using GIS (geographic information systems), to examine relations of environmental variables to ungulate distribution and habitat use. The database contains over 100 variables associated with vegetation, water, soils, roads, topography, and structural features such as fences. We describe database construction and documentation of GIS layers from 1987 to 1997. Error estimates associated with each variable or layer and sample applications of the database also are presented.
