To map the baseline distribution of sagebrush steppe, we included all sagebrush LANDFIRE Existing Vegetation Types (EVT) except for mountain big sagebrush, which is included in the foothill shrublands and woodlands community. We also included adjacent, low elevation (less than 2,600 m) grassland areas, which include postfire sagebrush steppe classified as grasslands and prairie grasslands that occur within the project buffer. All grassland EVT cells within a 210m radius buffer that were dominated by sagebrush steppe were included in the sagebrush steppe community. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with...

The "Broad-scale assessment of biophysical features in Colorado: Terrestrial development index using 5-kilometer moving window" raster dataset quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) for all lands in Colorado. The terrestrial development index (TDI) represents the total percentage of the estimated surface disturbance footprint from development within a 5-kilometer (km) radius moving window. The TDI scores range from 0 to 100 percent. Methods are described in the companion report (see "Larger Work" section).

General habitat model for Brewer's sparrow using repeat visit survey data collected in Wyoming as part of the Integrated Monitoring in Bird Conservation Regions program, White and others, 2013, between 2009 and 2012. A suite of occupancy modles with different environmental covariates were evaluated using program MARK, White and Burnham, 1999, and the top model for each species was used to model the breeding distribution. The map of suitable habitat was based on parameter values that included 90 percent of the locations; omission rate of 10 percent. This omission rate minimized commission errors based on a comparison with independent datasets from Idaho Fish and Game, Montana Natural Heritage Program, Utah Natural...

Delineated two aspen functional types, foothill and mountain slope aspen. Foothill aspen occurs at lower elevations, typically less than 2,621 m, within a matrix of sagebrush and other shrubs. Mountain slope aspen occurs across broad elevations from the toe slope to upper subalpine zones, where it intermixes with conifer species. LANDFIRE Existing Vegetation Types (EVT) includes two aspen EVT Rocky Mountain Aspen Forest and Woodland and Intermountain Basin Aspen and Mixed Conifer Forest and Woodland, which overlapped broadly in elevation and were not sufficient for use in distinguishing aspen functional types. Proximity analysis was used to delineate the two functional types. Because higher elevation aspen typically...

Terrestrial Development Index (TDI) for the Wyoming Basin REA project area. TDI scores are based on the percent of surface disturbance footprint from development within a 2.25km radius moving window for a 15m cell size. The TDI quantifies the total area of the surface disturbance footprint for five disturbance variable classes: transportation (roads, railroads), energy and minerals (oil and gas wells, wind turbines, mines), transmission structures (towers, transmission lines), and agriculture (pasture, cropland) and urban land covers. 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...

The “Biophysical assessment for indemnity selection of federal lands in Colorado: Development” dataset quantifies the estimated surface disturbance from development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) at several analysis scales for each of 89 Indemnity Units. The Indemnity Units are federal lands, currently managed by the Bureau of Land Management (BLM), under consideration for transfer of ownership to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. The companion data release (see "Cross Reference" section) was used to summarize the surface disturbance from development (development footprint) at...

The five needle pine (Limber and Whitebark) distribution was compiled from numerous data sources. The limber pine source distribution data compiled the Original Gap (ftp.gap.uidaho.edu) data (Note Utah does not have an explicit Limber pine class) and USDA Forest Service Individual Tree Species Parameter Maps (personal communication by Jim Ellenwood and Vern Thomas) as described at http://www.fs.fed.us/foresthealth/technology/remote_sensing.shtml. Limber pine (greater than 1 basal area). There is one large patch in SW Wyoming where original GAP data falsely identified limber pine (commission error) per Bob Means, BLM Wyoming State Forester. To address this commission error, these areas were replaced with ReGAP (codes...

Information on the biophysical features of federal lands identified as suitable for transfer to the State of Colorado was requested by the Bureau of Land Management (BLM). This information is intended for use in conducting an environmental assessment prior to transfer of ownership (conveyance) to the State. The Enabling Act of 1864 provided for the conveyance of federal lands to the State for the support of schools. If designated lands were unavailable for transfer at the time of statehood, the Act provided for the transfer of alternative federal lands in compensation, using a process referred to as “school-land indemnity selection.” To initiate indemnity selection, the Colorado State Board of Land Commissioners...
