David Burton, Aspen Delineation Project, 2070 Orange Drive, Penryn, CA 20060602 1 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/300_399/ds373.zip The database represents point locations and associated stand assessment data collected within aspen stands in the Plumas National Forest, Beckwourth Ranger District (Plumas County); field surveys and assessments were conducted by trained USFS staff. This is the current completed data set for aspen distribution of land administered by this agency. Aspen stands were assessed and delineated using a protocol developed by the lead investigators at the Beckwourth Ranger District. Data captures location and vegetative characteristics of aspen stands. Associated with this point layer is a polygon layer (PLUMAS_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. The database is an inventory of aspen stands in the Beckwourth Ranger District, Plumas National Forest, and an assessment of their ecological condition. 19990101 20030101 ground condition -121.112774 -120.086259 40.247547 39.679046 ISO 19115 Topic Category environment biota None Populus tremuloides Aspen Quaking aspen None Plumas County Plumas National Forest California None Post 2000 No constraints, public data Recognition that this data set was created by California Department of Fish and Game from information provided by agencies across California Department of Fish and Game.License: This work is licensed under Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

(2) GPS reading provide are for general geo-referencing. Beckwourth District location information was gathered using hand held GPS units using NAD 27 datum using the GPS track method (I.E. The track method creates smooth polygons from a continuous GPS collection (a track) along the entire perimeter of the aspen stand. Known caveats of the data: Caveats include: 1) the accuracy of the points representing the stand are limited by the quality of the GPS unit (2) Polygons layers were created using the GPS track method (I.E. The track method creates smooth polygons from a continuous GPS collection (a track) along the entire perimeter of the aspen stand. Some assessments were incomplete because stands were not physically accessible. Original location information was gathered using GPS units using NAD 27 data. Data was collected using the GPS track method (I.E. The track method creates smooth polygons from a continuous GPS collection [a track] along the entire perimeter of the aspen stand). Received data from Field Collection locations and Merged data into master aspen data set for California Department of Fish and Game. 20060101 Aspen Delineation Project David Burton Program Director mailing
