Summary

The database was designed to identify the location of each aspen stand in the National Forest and assess it ecological condition. The Eldorado National Forest uses the database as one step in the process of evaluating the need of management intervention.

Description

The database represents aspen stand locations and field assessments conducted in the Eldorado National Forest, Eldorado and Amador Counties, California. Data was gathered during the summers of 1999-2001. Assessments were conducted primarily by volunteers for the USDA Forest Service. Assessments were conducted within known aspen stands in the region, or stands identified during field surveys. The survey method was not intended to capture all known aspen sites in this region, and so this data does not represent a comprehensive map of aspen stands in the region. Aspen stands were assessed using a protocol developed by the Eldorado National Forest. Basic Information gathered included location and vegetative characteristics, and if browsing of the aspen was present or absent. Associated with this point layer is a polygon layer (ELDORADO_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.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Conceptual consistency
Measure description
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 hand help Garmin) (2) Polygons layers were created using limited # of points, field notes, and maps. The field crews collected data using a waypoint method. In this case the waypoint creates simple, rectangular polygons using a set of approximately three to six GPS points (waypoints) collected in selected areas along the edge of the aspen stand.




Data quality report - Completeness omission
Measure description
Some assessments were incomplete because stands were not physically accessible. Valid location with incomplete are included.




Data quality report - Quantitative attribute accuracy
Measure description
Significant general assumptions of the data are: 1) the protocol produces qualitative assessment information and is limited to the protocol use. (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 hand held Garmin GPS units using NAD 27 datum using a waypoint method. In this case the waypoint creates simple, rectangular polygons using a set of approximately three to six GPS points (waypoints) collected in selected areas along the edge of the aspen stand. Polygons were created by hand in a GIS merging GPS, field maps, and field notes.
