Klamath National Forest 20060601 1 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/300_399/ds370.zip The database represents polygons of aspen stands in the Klamath National Forest, Siskiyou County, California. The Klamath National Forest Region 5 Vegetation aspen layer was derived from LANDSAT TM imagery, SPOT imagery, orthophotos, aerial photos and auxiliary layers (Source data: Region 5 Forestland And Resource Data Base GIS And Oracle Data Dictionary 4/14/95'.) The stands were classified based upon conditions such as primary and dominant tree species, tree size, and tree density as determined by both the CALVEG system and California Wildlife Habitat Relationships system. Associated with this polygon layer is a point layer (KLAMATH_NF_KNF_VEG_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 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. The database was designed to identify the location of each aspen stand in the National Forest. Evaluation seral stage, tree size, primary and secondary dominant trees species, and vegetation category type was established. 20060601 unknown publication date In work As needed -123.203685 -121.690312 41.783268 41.543204 None Quaking aspen Populus tremuloides Aspen ISO 19115 Topic Category biota environment None California None Post 2000 No constraints, public data No constraints, public data.License: This work is licensed under Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).
