Summary

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.

Description

The database represents point locations and associated stand assessment data collected within aspen stands in the Klamath National Forest, Siskiyou County, California. The Ecological Unit Inventory is a data set compiled by the Klamath National Forest between 1991 and 1999. Aspen stands were interpreted using USGS 1m resolution grey scale aerial photography (DOQQ's) captured during the summer of 1993. The associated polygon layer (KLAMATH_NF_EUI_POLY) was digitized on a computer screen using the aerial photography to identify stand boundaries. The stands were evaluated based on criteria that included seral stage, tree size, primary and secondary dominant trees species, and vegetation category type. Associated with this point layer is a polygon layer (KLAMATH_NF_EUI_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 Ecological Unit Inventory data set produces information to location of stands where aspen are identified (2) Polygons layers were created using DOQQ and does not necessary represent the complete stand because of protocol errors.




Data quality report - Completeness omission
Measure description
Project completed.




Data quality report - Quantitative attribute accuracy
Measure description
Significant general assumptions of the data are: 1) Ecological Unit Inventory data set produces information to location of stands where aspen are identified. Does not pick up aspen stands were aspen can not be identified from DOQQs.




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
This protocol will miss parts of stands or complete stands that contain aspen that are not visible using DOQQs.
