This dataset represents current terrestrial intactness values (estimated at the 1km level) within the modeled distribution of the Barstow woolly sunflower (Eriophyllum mohavense). 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...

These data are statistical model outputs for Alkali mariposa-lily (Calochortus striatus ) species distribution, completed by Frank Davis’ Biogeography Lab at UC Santa Barbara. Predictions of habitat occupancy for ~70 species were generated from Maxent models for the CA Energy Commission’s project “Cumulative Biological Impacts Framework for Solar Energy in the CA Desert”, 500-10-021. Species distribution models were produced at 270 m resolution using a subset of 22 environmental variables. Models were evaluated with 10-fold cross validated AUC scores. Binary layers depicting predicted suitable habitat were derived using the equal training sensitivity and specificity threshold. For Calochortus striatus,...

This agriculture dataset was created by extracting out portions of the LANDFIRE (Refresh 2008, LF_1.1.0) EVT dataset within the DRECP 12km Boundary. This is a binary dataset, created for use in terrestrial intactness modeling. A cell value of 1 indicates the presence of one of the following agriculture catagories/classes at that location: 60 NASS-Orchard,61 NASS-Vineyard,62 NASS-Bush fruit and berries,63 NASS-Row Crop-Close Grown Crop,64 NASS-Row Crop,65 NASS-Close Grown Crop,66 NASS-Fallow/Idle Cropland,80 Agriculture-General,82 Agriculture-Cultivated Crops and Irrigated Agriculture,83 Agriculture-Small Grains,84 Agriculture-Fallow,85 Agriculture-Urban and Recreational Grasses.

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...

The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS. The NED provides the best available public domain raster elevation data of the conterminous United States, Alaska, Hawaii, and territorial islands in a seamless format. The NED is derived from diverse source data, processed to a common coordinate system and unit of vertical measure. All NED data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83). All elevation values are provided in units of meters, and are referenced to the North American Vertical Datum of 1988 (NAVD 88) over the conterminous United States. The...

These data are statistical model outputs for Bakersfield cactus (Opuntia basilaris var. treleasei) species distribution, completed by CBI. Predictions of habitat occupancy were generated from Maxent models for the DRECP. This species distribution model was produced at 270 m resolution for two limited extents within the DRECP region separately, east and west. The western Bakersfield cactus distribution model extent was defined as the portions of the following 5 USDA ecoregion subsections within a 25 km buffer of occurrences: Lower Batholith; Hardpan Terraces; South Valley Alluvium and Basins; Southern Granitic Foothills; and Elk Hills and South Valley Terraces. The western model used 107 detection points obtained...

This dataset is an extraction of riparian vegetation (invasive and non-invasive) from the NatureServe Vegetation. These data were then filtered to remove vegetation in washes and playas using the National Hydrography data, and then clipped to the DRECP 12 km buffered boundary. The dataset represents the work of multiple states and Federal agencies as part of the US Gap Analysis and LandFire programs. Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 acre. Landcover classes are drawn from NatureServe's...

CBI's expert model for Palmer's jackass clover (Wislizenia refracta ssp. palmeri) includes areas with "North American warm desert dunes and sand flats" vegetation, sandy soils (porosity of < 0.4), and elevations under 150 meters, in ecoregion subsection 322Bc.

These data are updated expert model outputs for Mohave tui chub (Siphateles bicolor mohavensis) species distribution for DRECP, completed by Dudek. Documentation from Dudek:A buffer of the known refugia has been applied to approximate suitable habitat for this species since it has been extirpated elsewhere and the refugia are isolated.

These data are statistical model outputs for Parish’s daisy (Erigeron parishii ) 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 USDA ecoregion subsections with occurrences and 10km buffer of occurrences, at 270 m resolution with 151 detections points obtained from Dudek and downloaded in March 2013 from CNDDB (California Department of Fish and Wildlife, Biogeographic Data Branch); Consortium of California Herbaria (http://ucjeps.berkeley.edu/consortium/), and USFWS Carlsbad Fish & Wildlife Office (http://www.fws.gov/carlsbad/GIS/CFWOGIS.html)....

This raster dataset is the result of a subtraction of the classification of raster datasets bhd2030us and bhd2000us. Both are produced using the SERGoM v3 model, they depict housing density for the coterminous US in 2030 and 2000, resp., and are based on 2000 US Census Bureau block (SF1) datasets. (The classication of the subtraction is shown below.) A raster layer that portrays not-developed (and assumed to be undevelopable) called CUS_UPP_100 depicts protected/unprotected lands and Census water polygons. First, Land was removed from blocks (reducing the area of a block, but not its number of housing units -- assuming that private housing units must be on private land) that was public and/or protected in the UNPROTPRIV100...

These data represent linkages where maintenance or restoration of ecological connectivity is essential for conserving biological diversity within the DRECP area. Current condition of linkages is represented by terrestrial intactness scores at 1km resolution, calculated by version 15a of CBI’s EEMS fuzzy logic model, which integrates multiple measures of landscape development and vegetation intactness.Linkages (which do not include wildland or habitat blocks) include the following:1) Linkages identified by SC Wildlands as part of the California Desert Connectivity Project (http://databasin.org/datasets/85d73316b5ab4816b56ed21787ed78a2). 2) Desert Tortoise TCA habitat linkages, representing least cost pathways...
