The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...
The riparian corridor was created based on previous maxent model completed by the Umpqua National Forest. In their methodology, NHD waterbodies and streams were buffered 100m to form the riparian corridor mask used my maxent.NHD water features (FCodes) included in the mask were:Playas, Lake/Pond, Lake/Pond: Hydrographic Category = Intermittent, Lake/Pond: Hydrographic Category = Perennial, Lake/Pond: Hydrographic Category = Intermittent; Stage = High Water Elevation, Lake/Pond: Hydrographic Category = Perennial; Stage = Average Water Elevation, Lake/Pond: Hydrographic Category = Perennial; Stage = Normal Pool, Reservoir, Reservoir: Reservoir Type = Aquaculture, Reservoir: Reservoir Type = Sewage Treatment Pond,...
Broad-scale alterations of historical fire regimes and vegetation dynamics have occurred in many landscapes in the U.S. through the combined influence of land management practices, fire exclusion, ungulate herbivory, insect and disease outbreaks, climate change, and invasion of non-native plant species. The LANDFIRE Project produces maps of simulated historical fire regimes and vegetation conditions using the LANDSUM landscape succession and disturbance dynamics model. The LANDFIRE Project also produces maps of current vegetation and measurements of current vegetation departure from simulated historical reference conditions. These maps support fire and landscape management planning outlined in the goals of the National...
Area boundary of allotments, exclosures, special resource areas and wild horse and burro territory.
To improve public health and the environment, the United States Environmental Protection Agency (USEPA) collects information about facilities, sites, or places subject to environmental regulation or of environmental interest. Through the Geospatial Data Download Service, the public is now able to download the EPA Geodata shapefile containing facility and site information from EPA's national program systems. The file is Internet accessible from the Envirofacts Web site (http://www.epa.gov/enviro). The data may be used with geospatial mapping applications. (Note: The shapefile omits facilities without latitude/longitude coordinates.) The EPA Geospatial Data contains the name, location (latitude/longitude), and EPA...
A 10 km moving window was used on the Sagebrush conservation element to determine the relative density of Sagebrush within the moving window.
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
Sagebrush vegetation communities were extracted from state ReGAP and Landfire Exisitng Vegetation (California only). The individual rasters were mosaiced to create a single raster than represent Sagebrush with the NGB ecoregion. Low sagebrush, Wyoming and Basin Big sagebrush and Mountain Big sagebrush were separated to be analyzed separately.
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
The 2030 Utah juniper viablitly was average based on the 7 climate models and clipped to the ecoregion.
USFS aquatic invasives database was used to count the number of detections within each analysis unit for the white sturgeon range.
Annual average wind resource potential of California, Idaho, Nevada, Oregon, Utah, and Wyoming at a 50 meter height within the Northern Great Basin.
The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Rails Shapefile includes all features within the MTDB Super Class "Rail Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB tha begin with "R". This includes main...
Using temperature range derived in earlier datasets for the range of redband trout in the ecoregion, the following assumptions are made of a future climate scenario.Suitable is Marginal is current Mean July Air Temp + 1 Standard Deviation - Max July Air Temp (32.2 - 35.6*C)Unsuitable is > current Max July Air Temp (> 35.6*C)Results are rolled up to an analysis unit.
The analysis units intersecting with the range of the species was extracted to use in other process models so that the entire range was analyzed.
The 2060 Utah juniper viablitly was average based on the 7 climate models and clipped to the ecoregion.
The shapefile ‘uscvals-aea.shp’ was re-projected to match the 30 m snap grid. Topo to Raster was used to convert the C factor to a raster. There was no metadata provided for this shapefile. Background on the wind erosion equation can be found at this website. http://www.weru.ksu.edu/nrcs/weq.htmlBackground on how the Climate Factor was developed can be found in the National Agronomy Manual released 4/01/203 in Section 502.
A 15km snap grid was used to align rasters from various datasets.
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
NOAA total mean monthly snow depth data represents the mean monthly total accumulation derived from 4km raster data. It does not incorporate melting, compression or sublimation. The data scoring categories were based on snow depth data categories, with snow depth greater than 20.4 inches considered low quality, 10.4 to 20.4 inches scored as moderate quality and less than 10.4 inches considered preferred.
