The database was designed to identify the location of each aspen stand in the National Forest. The purpose of the TEUIs is to identify ecological map units and ecological types and interpretations for ecosystem management and planning.
The database represents point locations and associated stand assessment data collected within known aspen stands in the Inyo National Forest, Inyo County, California. The Inyo National Forest assessed aspen as a part of the Terrestrial Ecological Unit Inventory (TEUI). This data were gathered during the summers of 2005. The purpose of the TEUIs is to identify ecological map units and ecological types and interpretations for ecosystem management and planning. The aspen are within the Potential Natural Vegetation (PNV) layer, which is a base layer of the TEUIs. The associated Polygon layer delineates stands based on dominant vegetation types from aerial imagery and field verification. Associated with this point layer is a polygon layer (INYO_NF_POLY) containing aspen stands delineated in conjunction with the aspen assessment information. Data Compilation: The Aspen Delineation Project (ADP) is a collaborative effort of the U.S. Forest Service's 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.
