Utility scale renewable energy development projects are currently proposed across the deserts of the Southwestern United States. Agencies that manage biological resources must understand the potential impacts of these projects and infrastructure (e.g., transmission corridors, substations, access roads, etc.) in order to select appropriate development sites and to mitigate for anticipated effects. Of major concern is determining how future development will impact wildlife movement and genetic exchange among core protected areas and whether increased fragmentation will impact species' abilities to adapt to changing environmental conditions. The adaptive and evolutionary potential of a species is ultimately dependent...

This dataset represents current terrestrial intactness values (estimated at the 1km level) within the distribution of Californian Mesic Chaparral. Terrestrial intactness is high in areas where development is low, vegetation intactness is high, and fragmentation is low. Consequently, this dataset serves as a general* indication of habitat quality within the distribution of this conservation element. Estimates of current terrestrial intactness were generated by an EEMS fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness, including agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious Surfaces), linear development...

These data are statistical model outputs for Tehachapi slender salamander (Batrachoseps stebbinsi ) species distribution, completed by CBI. Predictions of habitat occupancy were generated from Maxent models for the DRECP.This species distribution model was produced for a limited extent within the DRECP region, defined as a union of 10 km buffers of the Tehachapi slender salamander’s CWHR range (California Department of Fish and Wildlife, Biogeographic Data Branch, 2008) and detections, at 270 m resolution with 33 detections points obtained Feb. 2013 from CNDDB (California Department of Fish and Wildlife, Biogeographic Data Branch) and Herpnet (http://www.herpnet2.org/).The model was built with the following 5...

These data are expert model outputs for Bird: Arizona Bell's vireo - Vireo bellii arizonae (Primary, Breeding, Foraging) species distribution, completed by Dudek and ICF International.  Development of the species habitat models was a multi-step process involving a collaboration of biologists and GIS analysts. To facilitate this collaboration and to document the process, a DRECP species modeling Microsoft SharePoint site was created. The SharePoint site allowed biologists to select and parameterize the data layers considered important for the habitat model of each species. The selection and parameterization of the model for each species was based on the best available scientific information related to the species’...

These data are species distribution model outputs for the Mojave fringe-toed lizard (Uma scoparia) for the DRECP. Frank Davis’ Biogeography Lab at UC Santa Barbara used Maxent to produce a continuous probability surface and a binary layer showing suitable habitat, derived using the equal training sensitivity and specificity threshold. Based on consultation with biologists and occurrence data, the Conservation Biology Institute modified the UCSB binary model to include sand/dune complexes with known MFTL populations. Playas (based on the National Hydrography Dataset) were excluded from suitable habitat, and suitable sand features were selected from the DRECP Sand and Dune Systems dataset and National Hydrography...

This dataset shows the modeled distribution for California leaf-nosed bat, Macrotus californicus, within the boundaries of the Desert Renewable Energy Conservation Plan (DRECP). It is based on habitat identified for the DRECP from the DRECP Landcover dataset, which is based primarily on GAP vegetation data and community surveys by the California Department of Fish and Wildlife (CDFW). Other data used were mine data from the Department of Conservation, springs and seeps from the Geographic Names Information System, and California Ecological Sections from the USDA Forest Service.The California leaf-nosed bat model output was rasterized by CBI at 270m resolution and generalized using majority filter and boundary clean...

These data are updated expert model outputs for Greater sandhill crane (Grus canadensis tabida ) species distribution for DRECP, completed by Dudek. From Dudek's documentation:Because this subspecies uses freshwater wetlands as primary habitat and agricultural fields for foraging in winter, both agriculture and freshwater wetland vegetation types were selected to be included in the model as suitable habitat. In addition, freshwater emergent wetlands identified by the NWI were selected so that areas identified as freshwater wetland in this data layer as well as in the vegetation layer would be included in the model as suitable habitat. The model was restricted geographically by limiting the model results to those...

Solar, coal and gas power plant footprints within the DRECP 12km buffer study area. This dataset was created for the purpose of terrestrial intactness modeling. The polygons in this dataset represent the physical footprint of solar, coal, and gas power plants within the DRECP 12km buffer study area. Polygons were delineated with the intent purpose of encompassing infrastructure (e.g., buildings, solar panels) at each power plant facility as well as areas in the immediate vicinity which appeared to be degraded from human activities. This dataset was digitized in ArcMap 10.0 using "Bing Maps aerial imagery" provided by ESRI’s Basemap Service on 2/18/2013. Power plant locations were determined using U.S. Environmental...
