Summary

The purpose of this vegetation map is to aid in management of the Chimineas Ranch and American Ranch tule elk herds. The new mapping for this project has been seamed to existing maps to cover the range of the elk herds. The seamed map provides an inventory of habitat types for use in assessing the biological resources present in the area, in order to determine appropriate elk management strategies.

Description

The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) has created a fine-scale vegetation map of part of the range of the American Ranch and Chimineas Ranch tule elk herds. This section of the elk range is adjacent to the Carrizo Plain National Monument and the Chimineas Ranch Unit of the Carrizo Plain Ecological Reserve, both of which have been previously mapped. This map has been seamed to the vegetation map of the Chimineas Ranch completed by VegCAMP (VegCAMP 2010) and the map of the Carrizo Plain National Monument produced by the California Native Plant Society (Stout et al. 2013), and completes the range of these two elk herds in San Luis Obispo County, California. Like those maps, this 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 report, which is available here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92951 . Reconnaissance-level sampling of vegetation stands in the project area was conducted in the spring of 2013. Polygons were drawn using heads-up digitizing with true color 1-foot aerial imagery from August 1, 2007 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 1 acre, with the exception of wetland types, which have an MMU of acre. 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. Two sub-Group level mapping units were used in instances where the vegetation types could not differentiated on the imagery. The first mapping unit is composed of the Salvia leucophylla, Eriogonum fasciculatum, Artemisia californica, and Artemisia californica-Eriogonum fasciculatum Alliances; the second is composed of the Atriplex polycarpa and Atriplex canescens Alliances. Accuracy assessment (AA) data was collected in spring of 2014. Map accuracy was calculated to be 89%; corrections were made to the map based on the AA data to increase the final accuracy.

Supplemental information
Mapping Rules and Map Attributes Polygons were drawn using heads-up digitizing in ArcMap with true color 1-foot aerial imagery from August 1, 2007 as the map base. Although six years old at the time of mapping, this imagery was used for its high resolution and for consistency with the previous mapping of the adjacent CDFW lands and the Carrizo Plain National Monument, which also used it as the 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. Vegetation types were mapped to the NVC hierarchy level of Association, Alliance, or Group based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Two sub-Group level mapping units were used in instances where the vegetation types could not be differentiated on the imagery. The first mapping unit is composed of the Salvia leucophylla, Eriogonum fasciculatum, Artemisia californica, and Artemisia californica-Eriogonum fasciculatum Alliances; the second is composed of the Atriplex polycarpa and Atriplex canescens Alliances. Mapping Rules 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) - 1 acre for typical vegetation types (distinguished largely by overstory layer, when vegetation is not in a special type) - 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 the cover class is different) - 5 acre MMU for cover class break in the understory layer - 5 acre MMU for non-floristic breaks (height, clearing, 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 1:800 to 1:4000 (varied based on imagery, ease of interpretation, etc.) Imagery: Base: True-color 1-foot imagery flown for San Luis Obispo County on August 01, 2007 Supplemental: National Agricultural Imagery Program (NAIP) 2012 (summer) true color and CIR Ancillary: Other NAIP years, ESRI Basemap Imagery, Google Earth, Bing The complete metadata report, Vegetation Map of Elk Range Adjacent to Carrizo Plain Ecological Reserve and National Monument San Luis Obispo County, California, is available here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=92951.

Data quality report - Quantitative attribute accuracy
Measure description
VegCAMP staff conducted an accuracy assessment (AA) to validate that the vegetation map achieved at least an overall accuracy of 80%, the minimum acceptable by Federal Geographic Data Committee standards. The method that was used to allocate polygons was designed to ensure that all of the mapped vegetation types were assessed. Polygons were selected in excess of the count targeted for each type and were assigned a priority level based on whether the mapped type was rarely mapped (mapped less than 10 times), moderately common (mapped between 10 and 25 times), or common (mapped >25 times), with rarely mapped types having highest priority for the field crews to visit. Paper and digital field maps made use of the priority levels to guide field staff decisions regarding the time to spend to reach particular polygons, that is, since there were excess selected polygons, a field crew could decide to skip a low priority polygon that might require a long hike but decide to spend a lot of effort to visit a high priority polygon. A total of 198 vegetation polygons were allocated using the method described above; 19 were targeted as high priority, 63 were polygons of moderately common types, and 116 were polygons of the most commonly mapped types. Field staff collected data on 136 of those polygons; 13 high priority polygons, 52 polygons of moderately common types, and 71 polygons of the most commonly mapped types. In the office, data from the field AA forms was entered into an Access database and the vegetation type recorded by the photointerpreter (PI) was compared to the type determined in the field survey. Cover and disturbance attributes were not scored, but were provided as feedback to the photo interpreters for use in correcting the map. If the field crews could not identify the vegetation type based on the field key, a senior VegCAMP ecologist assigned the correct type, when possible, based on the species covers recorded, any additional notes taken by the field crews, and field photos. All field calls were reviewed and a "Final call" was recorded in the database when possible. Staff scored portions of the map that they did not map themselves. A fuzzy logic method was used to score each AA point, rather than simply denoting whether a sample was correct or incorrect (Gopal and Woodcock 1994; Congalton and Green 1999; Foody 2002; Hagen 2003; Metzler and Sader 2005). Each field-verified polygon was scored according to a set of decision rules, with a total of 5 possible points for each. Scores were summed for each vegetation type, then divided by the total possible score and multiplied by 100 for percent accuracy. The scored accuracy assessment samples were provided back to the photointerpreters, who corrected the map for specific and systematic errors.
