Summary

The purpose of the vegetation map is to provide an inventory of habitat types for use in assessing the biological resources present in the mitigation lands in order to determine appropriate management strategies. The map will also serve as a baseline for analyzing trends in habitat change in the future.

Description

The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) has created a fine-scale vegetation map of the Departments mitigation lands in the northern portion of the Carrizo Plain, San Luis Obispo County, California. The mapping follows Survey of California Vegetation, Federal Geographic Data Committee (FGDC), and National Vegetation Classification (NVC) standards (FGDC 2008, Jennings et al. 2009). The map legend is based on the classification in Stout et al. (2013), with slight modifications as discussed in Appendix C of the project report, which is available here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92969 . Reconnaissance-level sampling of vegetation stands in the project area was conducted in the spring of 2013. Polygons were drawn using heads-up digitizing using the July 2011 1-foot imagery acquired for San Luis Obispo County and downloaded from US Geological Survey (USGS) EarthExplorer as the map base. Supplemental imagery included National Agricultural Imagery Program (NAIP) true color and color infrared (CIR) 1-meter resolution data from 20102012, Bing imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is acre in order to capture small, remnant native stands of trees, shrubs, and bunch grasses. Mapping is to the NVC hierarchy Association, Alliance, or Group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Field verification data was collected in the spring of 2014 and corrections were made to the map based on that data to increase the final accuracy.

Supplemental information
Delineation Rules Polygons were drawn using heads-up digitizing using the July 2011 1-foot imagery acquired for San Luis Obispo County and downloaded from USGS EarthExplorer as the map base. Supplemental imagery included NAIP true color and CIR 1-meter resolution data from 20102012, Bing imagery, and current and historical imagery from Google Earth. The vegetation map was delineated according to the following rules: Minimum Mapping Unit (MMU): acre for special types (e.g., wetland, alkali scald, or localized type) acre for remnant, native tree, shrub, and perennial bunch grass stands. 1 acre for typical herbaceous vegetation types 10 meter width for linear polygons Polygon breaks (factors other than change in vegetation type): 3 acre MMU for cover class break in the overstory layers cover (i.e., when the adjacent vegetation is of the same classification unit but cover class is different) 5 acre MMU for cover class break in understory cover 5 acre MMU for non-floristic breaks (clearing, height, other urban features) 1 acre MMU for impact changes of 2 classes (e.g., from high to low, but not from high to medium) Delineation: Scale of 1:1000 to 1:4000 (varied based on imagery, ease of interpretation, etc.) Imagery: Base: San Luis Obispo County 2011 1-foot true color imagery Supplemental: National Agricultural Imagery Program (NAIP) 2012 (summer) true color and CIR Ancillary: Other NAIP years, ESRI Basemap Imagery, Google Earth, Bing The report, Vegetation Map of The Department of Fish and Wildlife North Carrizo Plain Mitigation Lands San Luis Obispo County, California, is available here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92969

Data quality report - Quantitative attribute accuracy
Measure description
This map deviates from Federal Geographic Data Committee Standards (FGDC 2008) in one respect: there was no formal accuracy assessment performed. However, 60% of all the polygons, encompassing 94% of the total mapped area, were validated by field reconnaissance or field verification survey data.
