The 17,158 acre Johnson Valley project area is located in San Bernardino County, 32 miles east of Victorville, CA bisected by highway 247. The fine-scale vegetation map was created as part of a collaborative project between the United States Geological Survey (USGS) and the Vegetation Classification and Mapping Program of the California Department of Fish and Wildlife (CDFW) to show the correlation between vegetation and geomorphology. The vegetation mapping types are based on the vegetation classification that was developed for the larger Desert Renewable Energy Conservation Plan (DRECP) mapping project (CDFW 2013). The vegetation classification was developed using a compilation of data collected for several projects including Anza-Borrego Desert State Park and Environs (Keeler-Wolf et al. 1998), the Mojave Desert Ecosystem Program''s Vegetation Database (Thomas et al. 2004), Vegetation of Joshua Tree National Park (La Doux et al. 2013), and Vegetation Classification and Mapping at Lake Mead National Recreation Area, Mojave National Preserve and Death Valley National Park (in progress, draft as of 2014).

The U.S. Bureau of Land Management (BLM) contracted Aerial Information Systems, Inc. (AIS) to continue vegetation classification development and fine-scale vegetation mapping of 1,016,668 acres over four subareas within Inyo, Kern, and Imperial counties of the Desert Renewable Energy Conservation Plan (DRECP) region. The four subareas are designated as Salton Sea South (224,763 acres), Jawbone South (204,133 acres), Owens Valley (392,906 acres), and Picacho (194,866 acres). Work performed is based on the classification and mapping standards as outlined in the Survey of California Vegetation, Classification, and Mapping Standards developed by the California Department of Fish and Wildlifes (CDFW) Vegetation, Classification, and Mapping Program (VegCAMP) (VegCAMP, 2020). California Native Plant Society (CNPS), as a subcontractor to AIS, conducted any classification development work needed for this project and conducted the accuracy assessment surveys. The subareas included in this map are Jawbone North (151,986 acres), Jawbone South (204,133 acres), and Owens Valley (392,906 acres). BIOS ds735 contains the other areas.The previous mapping for the DRECP region was conducted in two phases from 2011 to 2016 for the California Energy Commission. The maps were primarily produced to support the DRECP by helping planners more accurately identify high quality habitat and rare communities as they consider renewable energy sources and conservation opportunities. In 2011-2012 AIS and VegCAMP created a fine-scale vegetation map covering approximately six million acres of portions of the Mojave and Sonoran Deserts in southern California (Menke et al., 2013). In addition, mapping of 95,981 acres within Rice and Vidal Valleys in the Colorado Desert portion of the Sonoran Desert was completed by AIS in 2013-2014 as an extension to the original project. Subsequently, between 2014 and 2016, AIS was tasked to create a fine-scale vegetation map of 2,195,415 acres of desert in Inyo, San Bernardino, Riverside, and Imperial counties in southern California. Areas mapped include the eastern and central portions of the Mojave Desert as well as the Lower Colorado Valley (also referred to as the Colorado Desert), and the Arizona Upland subdivisions of the Sonoran Desert (Menke et al., 2016). The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new and previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of 2016 or 2018 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 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a 1 or 5 acre MMU, depending on type) and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). In the progression to non-desert areas the MMU transitioned to 1 acre for upland types and 1/4 acre for special types. Field reconnaissance and accuracy assessment enhanced map quality. There were a total of 126 mapping classes. The overall accuracy assessment ratings for the final vegetation map were 86.23 percent for Users Accuracy, and 87.9 for Producers Accuracy.Accuracy assessment ratings for the subareas included in this map are as follows:Owens Valley: Users Accuracy 83.9, Producers Accuracy 85.4Jawbone North: Users Accuracy 86.7, Producers Accuracy 85.5Jawbone South: Users Accuracy 82.8, Producers Accuracy 84.3For detailed information please refer to the following reports: Reyes, E., J.

This Vegetation Map of the San Felipe Valley Wildlife Area in San Diego County, California is based on vegetation samples collected in the field in 2002 and 2005 and on photo interpretation of a 2000 Color Infrared (CIR) Image. The map legend is based on classification of the plots and follows the hierarchical National Vegetation Classification System (USGS-NPS 2005) and Manual of California (Sawyer and Keeler-Wolf 1995). Types are cross-walked to California Wildlife Habitat Relationships (CWHR) and Holland types. No report was produced; this metadata serves to document the entire project. WHAT EACH RECORD REPRESENTS: Each record represents the attributes of the individual polygon in the map layer, including vegetation type, structural information, and disturbance information. The map represents vegetation as it existing prior to the 2002 Pines Fire. Polygons are attributed to the lowest level of the classification hierarchy allowed by the image resolution and comfort level of the photo interpreter. Thus, individual polygons are mapped to the Formation, Alliance or Association level. Several "mapping units" not in the vegetation classification were also used in the mapping classification (=map legend). The hierarchical classification and crosswalk allow mapping at coarser levels or in different systems (e.g., CWHR). If mapping at the Formation level (the "1000s" in the spreadsheet), please consider including the California juniper types 2106, 2171, 2172 and 2173 in the 4000s (Evergreen Shrubland). This juniper is considered a tree in the national classification, but is more shrub-like and its desert affinities make California juniper types fit more logically into the Evergreen Shrubland Formation.
