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 dataset depicts recreation sites compiled for BLM and USFS lands. Due to a general lack of quality recreation site information, this dataset likely under-represents the distribution and density of recreation sites, and only contains recreation sites on public lands. Additional recreation sites likely occur on state, local, and privately-owned land, but no data were available at the time of this REA. Recreation sites may have varying areas of impact, as some recreation sites may be large campgrounds whereas other sites are highly localized, such as trailheads. Source datasets had highly variable attributes. These attributes were not carried through into this dataset. Please see the source attribute in this dataset...
U.S. States represents the 50 states, the District of Columbia, and Puerto Rico of the United States.This dataset was used in the Northern Great Basin Rapid Ecoregional Assessment by BLM. No changes were made to the data but the dataset states within the ecoregion (California, Idaho, Nevada, Oregon, Utah and Wyoming.
This data set represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully...
This is a first cut at a statewide 1:63,360 coastline. The entire coasline, however, is not 1:63.360; only where data was available as of January 1998. It is a mixture of sources ranging from the Department of Natural Resources, Land Records Information Section hydrography database to the Exxon Valdez Oil Spill Environmentally Sensitive Index coastline (no ESI attributes included) to the US Geologic Survey hydrography to US Forest Service (in Prince William Sound). Where the 1:63,360 data was unavailable the 1:250,000 coastline was used to fill in. This information does not include lakes or streams. All streams are cut off at the mouth with a straight line. It excludes small islands that are difficult to visually...
To map connectivity, we assessed development levels for relatively undeveloped areas based on the regional Terrestrial Development Index (TDI) map (TDI scores less than or equal to 1 percent), and then used the resulting output to calculate patch size and structural connectivity metrics. We mapped the structural connectivity of relatively undeveloped areas (TDI less than or equal to 1 percent) at three inter patch distances based on connectivity analysis; local (1.8 km), landscape (2.25 km), and regional (3.51 km) scales. See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report for additional details at http://pubs.usgs.gov/of/2013/1223/.
5th Code HUC reporting units for the Colorado Plateau Ecoregion Used as analytical reporting units for aquatic conservation elements.
This dataset presents grazing allotments (from BLM and USFS) 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,...
This dataset represents the consolidated submissions for non-energy minerals and prospecting permit application data from BLM states responding to the WO 300 data call during the time period of November 2011 through May 2012. It is intended solely for use in the GRSG cumulative effects analysis. Source data, their acquisition methods and errors/omission rate vary. All original datasets used to create this dataset are stored in the BLM’s NOC E-GIS file structure. The paths to the original data are stored in this file’s attribute table. See the source data for detailed metadata and error analysis. Processing to develop this dataset: 1. Added a "Source" field to the attribute table of the original submission. 2. Populated...

This data was collected by the U.S. Bureau of Land Management (BLM) in Colorado. This dataset is meant to depict the surface owner or manager of the land parcels. In the vast majority of land parcels, they will be one and the same. However, there are instances where the owner and manager of the land surface are not the same. When this occurs, the manager of the land is usually indicated.
5th Code HUC reporting units for the Colorado Plateau Ecoregion Used as analytical reporting units for aquatic conservation elements.
ESRI file geodatabase of greater sage-grouse (Centrocercus urophasianus) range-wide breeding densities at 25% (BreedingDensity25), 50% (BreedingDensity50), 75% (BreedingDensity75) and 100% and the the current and historic distribution of potential habitat, or range, of the Greater Sage-grouse in Western North America were merged together. The current and historic distriubtion of potential habitat was initially researched and compiled by Dr. Michael A. Schroeder, research biologist for the Washington State Department of Fish and Wildlife. The initial draft of current and historic range data was mapped and submitted to state, federal, or provincial natural resource agencies and other experts for review, comment, and...

5th Code HUC reporting units for the Sonoran Desert Ecoregion Used as analytical reporting units for aquatic conservation elements.
Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified...

This simple assessment layer is used to answer management questions (MQs) about which high biodiversity sites (HBS) will experience significant climate change in the near future scenario in the Central Great Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas that have been identified by previous 3rd party analyses as having extraordinary biodiversity. It does not model actual response or condition of the HBS to climate change. Nearly all HBS 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...
