Summary

To have consistent representation of the different vegetation types in the MSHCP and to develop the best possible models for species distribution and abundance by addressing the needs of species' habitat at the appropriate resolutions.

Description

The California Department of Fish and Game (CDFG) contracted with the California Native Plant Society (CNPS) and Aerial Information Systems (AIS) to produce an alliance-level, vegetation classification and map of Western Riverside County, California. The resulting classification and map products will be used to help establish a monitoring basis for the vegetation and habitats of the Western Riverside County Multi-Species Habitat Conservation Plan (MSHCP). The plan aims to conserve over 500,000 acres of land out of the 1.26 million acre total. This area is the largest MSHCP ever attempted and is an integral piece of the network of Southern California Habitat Conservation Plans and Natural Community Conservation Planning (Dudek 2001, Dudek 2003). Riverside County is one of the fastest growing counties in California, as well as one of the most biodiverse counties in the United States. A wide array of habitats are found within the non-developed lands in Western Riverside County, including coastal sage scrub, vernal pools, montane coniferous forest, chaparral, foothill woodland, annual grassland, and desert. In the CNPS contract, vegetation resources were assessed quantitatively through field surveys, data analysis, and final vegetation classification. Field survey data were analyzed statistically to come up with a floristically-based classification. Each vegetation type sampled was classified according to the National Vegetation Classification System to the alliance level (and association level if possible). The vegetation alliances were described floristically and environmentally in standard descriptions, and a final key was produced to differentiate among 101 alliances, 169 associations, and 3 unique stands (for final report, see https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18245). In a parallel but separate effort by AIS (as reported in this dataset), vegetation mapping was undertaken through interpretation of ortho-rectified, aerial photographs for vegetation signatures in color infrared (CIR) and in natural color (imagery flown in winter or summer). A detailed map has been produced through the following process: 1) hand-delineation of polygons on base CIR imagery, 2) digitization of polygons, and 3) attribution of the vegetation types and overstory cover values. The map was created in a Geographic Information System (GIS) digital format, as was the database of field surveys. The dataset was produced through an on-screen photo interpretation procedure using three sets of geo-referenced imagery. The data is classified to a floristic classification derived through clustering analysis procedures based on species dominance and significance. The classification is based on the MCV (Manual of California Vegetation) in which 103 alliances and 169 floristic associations have been defined for the study area. Over 3300 full plot and reconnaissance points have been used in helping classify the mapped polygons. Mapped polygons are classified to either an association, alliance or mapping unit which may be an aggregation of associations or alliances. The dataset encompasses the western portions of Riverside County from the county boundary on the west eastward to the summit of the San Jacinto Mountains and Anza valley.

Supplemental information
Access the CNPS Vegetation and Mapping Classification for Western Riverside County and the final report of the Vegetation Alliances of Western Riverside County at: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18245. REFERENCE: J. O. Sawyer and T. Keeler-Wolf. 1995 "A Manual of California Vegetation", pub: California Native Plant Society, pp 471. Converted to California Teale Albers NAD83 by the California Department of Fish and Game. MODIFICATIONS: 03/2015 An update to the 2005 map was completed. The map update covers 1,014,364 acres of the original 1.2 million acres mapped in 2005 and was produced using the 2012 NAIP imagery as the base. Areas which were include in the 2012 map update were removed from this version of the 2005 map. 03/2015 An update to the 2005 map was completed. The map update covers 1,014,364 acres of the original 1.2 million acres mapped in 2005 and was produced using the 2012 NAIP imagery as the base. Areas which were included in the 2012 map update were removed from this version of the 2005 map. 4/2006 - Two versions of the shapefile existed: one from Aerial Information Systems with corrected values for the DENSITY, EXOTICS, and CLEARED attribute fields; and one from the California Native Plant Society with corrected values for the PI, COM_NAME, SCI_NAME, WHR_CODE, WHR_NAME, and MSHCP_COLL attribute fields. The corrected attribute values for these two versions were merged into one shapefile based on the unique ID attribute field, WRIVVEG_. In the process, it was discovered that the supposedly unique ID attribute field, WRIVVEG_ID, was not unique and was redundant, so it was dropped. Post-merge attribute domain checking revealed that non-standard values were being used for WHR_CODE, WHR_NAME, and MSHCP_COLL. In consultation with CNPS, these values were corrected. Minor errors were also discovered in the metadata; these were also corrected.
