This data represents a draft âIntegratedâ alternative from the DRECP Description and Comparative Evaluation of Draft DRECP Alternatives dated December 17, 2012. Each integrated alternative is comprised of three primary elements: Renewable Energy Development areas, Conservation Area Reserve System areas, and Other Lands.The Renewable Energy Development areas include Development Focus Areas (DFAs) in all alternatives and in Alternatives 1, 6, and 7 also include Solar PEIS Variance lands.The Conservation Area Reserve System includes three components: the BLM Land Use Plan Amendment (LUPA) areas, Conservation Planning Areas, and Existing Conservation. The BLM LUPA areas are comprised of Desert Conservation Lands...
Desert Renewable Energy Conservation Plan (DRECP) Boundary with 12km buffer
This is an aggregate dataset for the DRECP 12 km buffer region, depicting the geographic boundaries of Grazing Allotments within BLM managed public lands. An allotment is an area of land designated and managed for grazing of livestock (43 CFR 4100.0-5). An allotment may include private, state, and public lands under the jurisdiction of the Bureau of Land Management and/or other federal agencies. An allotment may be subdivided into pastures. Range improvement projects are not depicted within this dataset.
Vegetation Departure (VDEP) data product ranges from 0 - 100 to depict the amount current vegetation has departed from simulated historical vegetation reference conditions. This departure results from changes to species composition, structural stage, and canopy closure. VDEP is calculated based on changes to species composition, structural stage, and canopy closure using methods described in the Interagency Fire Regime Condition Class Guidebook. LANDFIRE VDEP is based on departure of current vegetation conditions from reference vegetation conditions only, whereas the Guidebook approach includes departure of current fire regimes from those of the reference period. LANDFIRE simulates historical vegetation reference...
The desert bighorn sheep mountain habitat data provided by  Diane Mastalir (California Department of Fish and Wildlife) is intended to identify historic, current, and potential core habitat for desert bighorn sheep in California (excluding the Peninsular bighorn sheep).This layer represents mountain habitat with a slope of 15% or greater. It was created using a NED 30 meter resolution DEM clipped to the study area. Slope of 15% or greater was extracted from the 30 meter DEM. A conditional evaluation was performed on the image giving the output cell a value of 1.This dataset was resampled from 30m to 270m resolution by Conservation Biology Institute and generalized using majority filter and boundary clean techniques....
This dataset represents current terrestrial intactness values (estimated at the 1km level) within the distribution of Inter-Mountain Dry Shrubland and Grassland. 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),...

This dataset displays the Vector Ruggedness Measure (VRM) for the DRECP study site and surrounding 12 km buffer at 270m resolution. This dataset was originally derived at 30m resolution, using the 30m NED, and run with a 9x9 (270m) neighborhood size. The resulting VRM dataset was projected to CA Albers Equal Area NAD83 and resampled to 270m resolution to match the DRECP statistical species distribution models. The Vector Ruggedness Measure measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures...

Riparian invasive species distribution within the DRECP study area; created for use in terrestrial intactness modeling. This dataset is binary. A cell value of 1 indicates the presence of one or more invasive riparian species at that location. A cell value of 0 indicates the absence of riparian invasives at that location. This dataset was created by combining the following classes from LANDFIRE EVT V1.1, NatureServe Landcover, Jarnevich, et al., and Tamarisk 1965 line. LANDFIRE EVT V1.1 2180: Introduced Riparian Vegetation NatureServe Landcover 8480: Introduced Riparian Vegetation Jarnevich, et al (modeled Tamarisk) Thresholded at 0.6 Tamarisk 1965 line (http://www.tamariskmap.org) All line features...
These data represent Palm Springs Little pocket mouse (Perognathus longimembris bangsi)Â detections, clipped to the DRECP boundary. 72 detections points obtained Feb. 2013 from CNDDB (California Department of Fish and Wildlife, Biogeographic Data Branch), MaNIS (http://manisnet.org/), and species locality data compiled by the California Mammal Species of Special Concern (MSSC) project.The DRECP has obtained special permission from the CA Dept. of Fish & Wildlife to display these data on public maps at scales smaller (more zoomed out) than 1:250,000. These data are not visible on maps zoomed in beyond this scale.Disclaimer: These data are not a complete representation of all available species data. There may be...
