Vegetation - Pickel Meadows Wildlife Area [ds3197]

The primary purpose of the project was to further CDFW’s goal of developing fine-scale digital vegetation maps as part of the California Biodiversity Initiative Roadmap of 2018. CDFW's VegCAMP developed the floristic vegetation classification used for the project based on existing vegetation types described in the Manual of California Vegetation Online (CNPS 2021) and the classification for the Modoc ecoregion (Boul et al. 2021).

The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The vegetation classification and mapping report with the vegetation key can be downloaded here: nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=237989. The vegetation map was produced applying heads-up digitizing techniques using a 2018 base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources.

Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland and riparian types, which have an MMU of ½ acre. Field reconnaissance and accuracy assessment enhanced map quality.

There was a total of 33 mapping classes. The overall Fuzzy Accuracy Assessment rating for the final vegetation map , at the Alliance and Group levels, is XXXX percent . Overall users' map accuracy was 89.3% and overall producers' accuracy was 89.6%.
