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...
This report presents information about subsistence uses of fish, wildlife, and plant resources in Lime Village, Interior Alaska. This is the first harvest assessment survey for this community since a compilation of qualitative harvest data was completed in 1983. The Alaska Department of Fish and Game Division of Subsistence conducted the project in collaboration with Stephen R. Braund & Associates as part of a multiyear, multiphase study in a region of Southwest Alaska being considered for the development of a large scale mine. The Pebble Project is a mineral deposit in an advanced exploration stage located near Frying Pan Lake, which is 100 miles south of Lime Village. The Pebble Project requires updated baseline...
Structural connectivity of baseline mule deer crucial winter range in the Wyoming Basin Rapid Ecoregional Assessment project area. We mapped the structural connectivity for local connectivity (1.8km), landscape connectivity (5.31km), and regional connectivity (11.79km).. See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
Distance (m) to Perennial Water within the Wyoming Basins Ecoregional Assessment area, produced by Hanser and others, 2011 (Hanser, S. E., M. Leu, S. T. Knick, and C. L. Aldridge, eds. 2011.

This layer represents the near-future scorecard of one indicator of ecosytem integrity. This ecosystem assessment is for projected 2025 landscape condtion (LCM). NatureServe’s ecological integrity framework provides a practical approach to organize criteria and indicators for this purpose (Faber-Langendoen et al. 2006, Unnasch et al. 2008). This framework provides a scorecard for reporting on the ecological status of a given CE within a given location, and if needed, facilitates the aggregation and synthesis of the component results for broader measures of ecological integrity at broader scales. Please see "cmbrCE and indicators.xlsx" for a complete list of which measures were applied to individual CEs for current...
Some of the YKL rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - This file includes a downscaled projection of decadal mean Day of Freeze (in ordinal dates) for the decade 2060-2069 at 771x771 meter spatial resolution. Day of Freeze approximates when the running mean dips below 0°C. Although raster values represent ordinal dates, the values 0 and 365 are special classes. A value of 0 indicates...
This dataset contains reclassified GAP land cover data for grasslands in the middle rockies ecoregion.
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/.
The Monitoring Trends in Burn Severity (MTBS) project assesses the frequency, extent, and magnitude (size and severity) of all large fires (includes wildfire, wildland fire use, and prescribed fire) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period of 1984 through 2011. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer...
Terrestrial Development Index (TDI) for transportation in the Wyoming Basin REA project area. TDI scores are based on the percent of transportation surface disturbance footprint from development within a 2.25 km radius moving window for a 15m cell size. The TDI quantifies the total area of transportation surface disturbance footprint. TDI scores range from 0 to 100 percent and were divided into seven classes for visualization purposes. Because the development scores are continuous, alternative classes can be used to display the data to address a particular management question. For additional information see the Development Chapter 4 and the Appendix in the Wyoming Basin REA Open File Report.
This dataset shows areas of increased or decreased potential for human or naturally-caused fires between Maxent projections based on near-term climate and current climate.
The Vista tool is used to create a Scenario of the CAs affecting the North American Warm Desert Riparian Woodland, Shrubland, Mesquite Bosque and Stream CE and applies user-input Landscape Condition Model (LCM) scores to generate ESAs for each of the CEs. The LCM consists of Site Impact scores and impact Distances for each CA category. Site Impact scores are a value between 0 and 1 representing the impact of the CA on the relevant CEs. A score close to 1 indicates negligible or no impact from that CA. A score close to 0 indicates the highest possible impact, e.g. an interstate highway that makes the area in which it occurs completely unsuitable for the CE. Distances are set in meters and extend the impact of the...
This dataset shows a series of fragmentation metrics for natural vegetation for a watershed (HUC5) reporting unit. These metrics were calculated using FRAGSTATS. For more information about FRAGSTATS, or the methods used to calculate these metrics, please see: http://www.umass.edu/landeco/research/fragstats/fragstats.html A 90 meter edge distance was used to define core area within patches.
Utah Division of Wildlife Resources Mule Deer range data
Mapping of terrestrial vertebrates focuses on linking a spatial representation of species-habitat matrices to geographic distribution. Each model is a combination of distribution from regional and state references in association with contiguous appropriate habitats. Ranges for all species were based on 8-digit HUCs. Habitats were based on a raster SWReGAP 1 acre MMU land cover data set, with hydrology habitats added in from USGS NHD dataset directly or through modeling. Habitat association information was obtained from various state, regional, and national references with updates from scientific literature. This portion of the Southwest Regional Gap Analysis Project produced predicted habitat distribution maps for...
5th Code HUC reporting units for the Colorado Plateau Ecoregion Used as analytical reporting units for aquatic conservation elements.
This dataset was created as a way to have standard fish distribution datasets across the various fish species for the study area. This was needed because the original source datasets for fish distributions came from several different sources and were at various scales and also overlapped. To fix the issues in the source datasets we walked the original data over to the NHD Plus hydrography.
Average annual temperature for 2076-2090 projected by the GFDL 2.1 GCM run 1 driven by the A2 emissions scenario at 1/8 degree latitude-longitude (approximately 12km by 12 km) over the Wyoming Basin and surrounding areas. BCSD data downloaded the "Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections," archived at http://gdo-dcp.ucllnl.org/downscaled_cmip_projections/.
Difference of Potential Evapotranspiration simulated by the biogeography model MAPSS using RegCM3 climate with GFDL projections as boundary conditions. Units are millimeters of water. MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid (http://www.databasin.org/climate-center/features/mapss-model). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation) as well as soils information (texture, depth). Based on a set...
