Summary

This project serves two complementary functions. The first is to develop a detailed vegetation inventory to assist the Bureau of Land Management in the development of long-range management decisions in the area, which has a range of uses from a wilderness study area to grazing, mining, and off-road vehicles. The second is to provide a test case for the development of vegetation mapping methodologies with recommendations to the California State Vegetation Memorandum of Understanding Committee. The classification and descriptions produced herein have been used to develop detailed maps of the areas vegetation, and these maps are compared to other existing maps in the area to test their accuracy and efficiency of production.

Description

California Native Plant Society (CNPS) and California Department of Fish and Wildlife (CDFW) cooperated to created a detailed vegetation inventory to assist the Bureau of Land Management in the development of long-range management decisions in the area, which has a range of uses from a wilderness study area to grazing, mining, and off-road vehicles. In the spring and summer of 2004 and 2005, a field crew of vegetation ecologists collected 570 vegetation rapid assessments. In the fallwinter of 2004-2005, these data were entered into a database and analyzed using multivariate statistical programs to develop a floristic classification, keys, and descriptions of the vegetation types identified in the area. AIS then did a fine-scale mapping based on the classification which was compared to mapping based on CalVeg methodologies. This provided a test case for the development of vegetation mapping methodologies with recommendations to the California State Vegetation Memorandum of Understanding Committee.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Quantitative attribute accuracy
Measure description
The validity of a vegetation map is accomplished when its accuracy is at least 80% or greater (USGS NPS, 2005). The fine-scale map showed legitimate accuracy for its vegetation attribution, with accuracy values averaging around 86%. This was assessed by holding out 80 of the field surveys from the delineation process, and checking the type of the photointerpreter vs. the type determined by the survey.




Lineage

Source data
Description
CIR imagery flown in June 2004 was used as the imagery base for the map. It is approximately 1 ft. resolution.
