This categorical CWD raster was developed from a project-wide CWD raster. For each of the five fracture zones, the CWD raster was partitioned into zone-specific, 10 equal-area class map, ranging from low CWD to high CWD.
Satellite imagery from the Landsat 5 Thematic Mapper sensor and the Landsat 8 Operational Land Imagery were used to investigate changes in overall evergreen vegetation occurring between the 1986-1989 and 2013-2014 time periods. Two path/rows of imagery, from the spring, summer, and fall seasons for each time period were mosaicked together. The imagery was then subset to remove the presence of clouds from the datasets. Images were further subset using the impervious data from the 2011 version of the National Land Cover Database. Unsupervised classification was used to spate each time period imageinto two classes, evergreen vegetation and everything else. Each subsequent time period was subjected to successive unsupervised...

Ten focal species cost-weighted distance (CWD) surfaces from WHCWG (2010) were combined into a single categorical raster for this project. The source focal species were: western toad, northern flying squirrel, wolverine, Canada lynx, American marten, mountain goat, American black bear, elk, mule deer, and bighorn sheep.

This cost-weighted distance (CWD) raster was developed from a generalized shrub-steppe and grassland (SSGL) species guild resistance model based on 20th percentile of resistance values for the five statewide analysis (WHCWG 2010) focal species in this biome, including sage-grouse, black-tailed jackrabbit, white-tailed jackrabbit, badger, and sharp-tailed grouse.

The purpose of this project was to develop a spatially explicit occupancy model for grizzly bears across the full extent of the CCE. The landscape occupancy model was created using ecological variables compiled for the CCE by the CMP and grizzly bear detection data provided by our partners in Alberta, British Columbia, and Montana.

These data represent land cover and land use for the Crown of the Continent Ecosystem. The data are a compilation from multiple sources [Multi-Resolution Land Characteristics (MRLC) Consortium, Agriculture and Agri-Food Canada (AAFC), and the Canadian Forest Service (CFS)], Canadian data are circa 2000, US are circa 2001. VALUE: 0 = NoData; 20 = Water; 30 = Barren; 31 = Ice/Snow; 34 = Developed; 50 = Scrub/Shrub; 80 = Wetland; 110 = Grassland; 120 = Agriculture; 210 = Coniferous; 220 = Deciduous; 230 = Mixed. This dataset was published in November 2010. The dataset was updated in 2014 to fix several no-data pixels along the US-Canada border. This dataset was developed by the Crown Managers Partnership, as part of...

This is a land cover dataset for Nebraska that was most recently updated in 2020 by the Rainwater Basin Joint Venture. This metadata record supplements the complete description of the data in Bishop, A., Grosse,R., Barenberg, A., Volpe, N., and Riens, J. January, Nebraska Land Cover Development Version 2016. Rainwater Basin Joint Venture, U.S. Fish and Wildlife Service, Grand Island, Nebraska.

Seamless DEM for the Crown of the Continent Ecosystem with a 50km buffer. This DEM was created using Shuttle Radar Topography Mission (SRTM) 1 Arc-Second Global data. The SRTM DEM had nodata values in several regions, particularly mountain tops. NoData holes were filled with ASTER Global DEM Version 2. Note: While the ASTER Global DEM does not have the NoData problems, the layers derived from the ASTER DEM (ex: slope, aspect) have sensor anomalies and artifacts, especially visible in the prairie regions. Data originally in WGS 1984 Vertical height in meters DEM created 2016-Feb-09

The Human Modification (HM) model is designed to provide a comprehensive, but parsimonious approach, that uses several stressor/threats datasets to estimate level of human modification. There are three important elements that define the HM approach: (a) the human modification stressors and their data sources (b) the measurement unit used for each stressor, and (c) the method used to combine the effects of multiple stressors into an overall score of human modification. The way in which these various data layers are combined into a single index is quite important. We use a method that minimizes bias associated with non-independence among several stressor/threats layers (Theobald 2013). The HM model assumes the contribution...

These raster files showing wetland areas that were functional during Rainwater Basin Wetland Complex Annual Habitat Survey. Annual Habitat Surveys (AHS) identify areas of wetland ponding and function (ponding and potential hydrophyte vegetation) during spring migration. The information is developed by Rainwater Basin Joint Venture to identifying how much habitat the Rainwater Basin Wetland Complex provides to migratory waterfowl on an annual basis. AHS have been completed for 2004 and 2006-2020 where high-resolution aerial photos of the Rainwater Basin Wetland Complex are classified using an image object classification software to determine land cover (hydrophyte water, agriculture water, hydrophytes, agriculture,...

The landscape permeability model represents the structural connectivity of sagebrush ecosystem habitat in the Green River Basin (including ~5-10 km boundary outside of the GRB. This model connects patches of habitat, across the landscape using resistances that represent the degree of human modification and slope (energetic costs), using the Multi-Scale Landscape Permeability model (Theobald et al. 2012; Theobald unpublished). We used two metrics: (a) patch importance and (b) betweeness centrality amongst patches. These metrics were summarized for each HUC12. This dataset represents the vulnerability of sagebrush ecosystem permeability to human modification summarized for each HUC12 watershed within the Green River...
