Lassen 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/ds371.zip The database represents point locations and associated stand assessment data collected in aspen stands in the in the Eagle Lake Ranger District, Lassen National Forest, Lassen County, California. Data were gathered during the summers of 2001-2005. Observations were conducted by trained Forest Service crews. Assessments were conducted within aspen stands in the region, or stands identified during field surveys. This dataset is considered to be a complete inventory of aspen in these watersheds, based on the extensive effort to survey all stands in the region. Aspen stands were assessed and delineated using a protocol developed by the lead investigators at the Eagle Lake Ranger District. Assessments included information describing the ecological condition of the aspen stand, and if browsing of the aspen was present or absent. Associated with this point layer is a polygon layer (LASSEN_NF_EAGLELAKE_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 was designed to identify the location of each aspen stand in the Ranger District and assess it ecological condition. The Eagle Lake Ranger District and Lassen National Forest uses the database as a step in the process of evaluating the need of management intervention. 20010101 20050101 ground condition -121.303329 -120.587601 40.848643 40.204874 ISO 19115 Topics Category environment biota None Populus tremuloides Aspen Quaking aspen None Eagle Lake Ranger District Lassen National Forest Lassen County California CA 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.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 and not for providing the exact boundary of any stand. Original location information was gathered using Trimble GPS units using NAD 27 data 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 (i.e. a Trimble unit) The field crews collected data using 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. >95% of Ranger District was cover in assessment.
