Aspen Delineation - Inyo National Forest [ds366]

Potential Natural Vegetation (PNV) coverage for all lands within the Inyo National Forest, including Sierra and Humboldt-Toiyabe National Forest lands administered by the Inyo NF without regard to land ownership. The coverage does not include large blocks of private, state, county, Dept. of LA Water and Power, or other federal lands such as Long Valley, or the Owens Valley. Associated with this polygon layer is a point layer (INYO_NF_PTS) containing aspen stand assessments conducted in conjunction with the aspen stand delineations.

Data Compilation: The Aspen Delineation Project (ADP) is a collaborative effort of the U.S. Forest Services Pacific Southwest Region, the California Department of Fish and Games Resource Assessment Program, and the California Office of Bureau of Land Management. Principal Investigator for ADP is David Burton; visit: www.aspensite.org for more information regarding the ADP. The Department of Fish and Games, Resource Assessment Program compiled this information from the collaborating agencies and other researchers, and formatted the data into a common database for the purpose of facilitating access to data related to the conservation of Quaking Aspen in California.

This information portal falls within the ADP goals to help agencies and land managers identify, map, treat, and monitor aspen habitats. This dataset is a portion of a master database compiled during a year long effort in 2005 to pull together current GIS layers and maps depicting Aspen communities in California.
