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.
This raster dataset represents Places II: Specially Designated Areas of Ecological and Cultural Value within the Mojave Basin and Range. These sites represent legally protected lands and waters. Plus lands that have been identified as known recovery lands (e.g. critical habitat recommended for recovery of Desert Tortoise and recovery units identified for the CA red legged frog).
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...
This dataset presents special designations within the context of current and near-term terrestrial intactness and long-term potential for energy development and potential for climate change (4KM reporting units). Current terrestrial intactness is based on current measures of landscape development, fire regime and vegetation impacts, and fragmentation. Near-term intactness includes estimates of urban growth and expansion of invasive vegetation. Long-term potential for energy development is based on areas of potential for wind, solar, and petroleum development derived from multiple sources. Long-term potential for climate change is based on absolute changes in runoff, precipitation, temperature, and vegetation change...
This raster is used to answer management questions (MQs) about where conservation elements (CEs) overlap with areas of high wind energy potential in the Mojave Basin and Range Ecoregion. The value indicated in the raster represents a normalized score between 0-1, the lower the value the few species and poorer modeled landscape condition (ecological integrity) expected. The higher the score, the more species and higher condition are expected. This layer seeks to address an article in the BLM Statement of Work 1.1.1 stated, Areas with High Potential for Renewable Energy Development (Required) (The Contractor shall a) locate areas identified (e.g., by DOE, USGS) as suitable for wind, solar, geothermal, and biomass...
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM Herd Management Areas (HMAs) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with areas managed for wild horses and burros in the western US. It does not model actual response or condition of the HMAs to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others are broader...
This simple assessment raster is used to answer management questions (MQs) about which grazing allotments (GAs) will experience significant climate change in the near future scenario in the Mojave Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas of public land that are leased to private entities for grazing by livestock. It does not model actual response or condition of the GAs to climate change. Nearly all GAs in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes. Cells that represent...

This data is a model of potential habitat connectivity for the Mojave desert tortoise (Gopherus agassizii) for the Mojave Basin and Range ecoregion. Methods for developing this data set: The connectivity modeling software Circuitscape 3.5.7 was used to develop the desert tortoise model. The two inputs needed to model tortoise habitat connectivity with this software were developed in ArcGIS 10. Habitat Input: The USGS model for desert tortoise habitat potential was used to create a series of 167 points representing tortoise habitat throughout the Mojave Basin and Range ecoregion. Areas with high habitat potential (0.7 or higher) were selected and converted to polygons. Polygons smaller than 4,000 acres were removed....
This data set represents an updated Ecological Subsection Map for Northern Alaska. This revision focused on correcting coding errors identified in the 2012 revision. The 2012 revision was a major revision and it focused on completing the incompletely mapped portion of the southern NPRA, improving mapping of glacial and outwash deposits within the Brooks Foothills, and improving consistency with existing surficial and bedrock geology maps in northern Alaska. The 2012 revisions resulted in 525 ecological subsections, nested within 55 ecosections and 12 ecoregions covering 411,781 km2. Attributes for the polygons include information on physiography, generalized geology, lithology, and referenced information sources....
Terrestrial subregions were used in this Rapid Ecoregional Assessment (REA) to summarize results where the trend by conservation element (CE) was not evident or the change agent (CA) results were not presented as a spatial product (as in the ALFRESCO) output. The North Slope study area contains nine terrestrial subregions: Western Coastal Plain - Central Coastal Plain - Eastern Coastal Plain - Western Foothills - Central Foothills - Eastern Foothills - Western Brooks Range - Central Brooks Range - Eastern Brooks Range. These subregions are nested within three main arctic ecoregions as defined by Nowacki et al. 2001 and facilitate data summarization that illustrates both north to south and west to east gradients...
This is an aggregate national dataset describing the geographic boundaries of the ACEC within the BLM managed public lands. The designated ACECs are "areas within the public lands where special management attention is required to protect and prevent irreparable damage to important historic, cultural, or scenic values, fish and wildlife resources or other natural systems of processes, or to protect life and safety from natural hazards." This metadata was extracted from the ACEC file geodatabase feature class; however, due to ArcGIS bugs most metadata was lost.

This raster represents development change agents (CAs) in the Mojave Basin and Range Ecoregion for the current (circa 2010). In the scenario-based assessment of conservation elements (CEs), this raster has been developed to represent CAs in a clear, combined format and to answer the management questions (MQs) such as, where do CAs intersect CEs? The raster contains 19 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others are broader land cover types derived from spatial models (development, mining and refuse areas). During the construction of the layer, we observed that many CAs...

Proposed Visual Resource Management (VRM) classifications within the Western Oregon Plan Revision (WOPR) area. These classes are based on scenic quality, sensitivity level, and distance zones. Managed VRM are areas which include Inventoried VRM and may include other external factors such as proximity to state highways or resource designations. Adjustment are made based on true ground designations.BLM (Bureau of Land Management) WOPR (Western Oregon Plan Revision) WOPR Theme Group: LUP (Land Use Planning) PRMP (Proposed Resource Managment Plan) VRM (Visual Resource Management)
