Summary

The final products will assist agencies and other interested organizations in fire modeling, resource protection, and restoration efforts. The Nature Conservancy (TNC) will use the map to help predict changes in vegetation resulting from variations in the frequency of fires as well as help land managers determine where prescribed fires will be of most benefit.

Description

In 2007 Aerial Information Systems, Inc. (AIS) was contracted by the California Native Plant Society (CNPS) to produce a vegetation map for approximately 100,000 acres of foothill and valley fringe regions west of Lassen National Park. Included within the mapping area were the Dye Creek Preserve and Tehama Wildlife Area in addition to the Denny Ranch property in the northwestern portion of the study. The study area covers a variety of habitats found in the lower elevations of the southern Cascade Range foothills including blue and interior oak woodlands, valley oak riparian forests and several chaparral communities. The vegetation of the region was defined by using existing CNPS survey data and by CNPS collecting additional field surveys (with an additional 180 reconnaissance surveys performed by AIS) for help in photo signature training. This information will support a standard floristic vegetation classification at the alliance and sub alliance level, along with a vegetation mapping classification at levels which are discernable using the 1-meter imagery. The map units attempt to correlate to defined Alliances and Associations when possible as described by a CNPS Sierra Nevada Foothills Vegetation Classification. However, some map units may not exactly correlate due to imagery limitations.

Data Quality

Resource level dataset




Data quality report - Quantitative attribute accuracy
Measure description
Out of the 450 surveys taken, 307 field verification surveys were used for a rigorous error analysis of the mapped vegetation attributes as well as canopy cover attributes. Thirty vegetation types were evaluated in the accuracy assessment, representing 81% of the total number of mapped types. For every assessment that scored below a value of 3, a CNPS ecologist and an AIS photo-interpreter reviewed the polygon, so that changes could be made to increase the final map product's accuracy. The map classes shown in this document represent those that remained or were created following adjustment of map classes to improve the map accuracy. For the final assessed map units, the overall user's accuracy averaged 85%.
