All data layers included in this data release were created using the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET) tool, which relies on spatial inputs on species distributions and likelihood of restoration success to select parcels for sagebrush restoration. The PReSET is a workflow that relies on the prioritizr package in program R to identify parcels for effective and meaningful sagebrush restoration. Inputs into the tool included occupancy data layers for six focal species (Brewer’s sparrow (Spizella breweri), sagebrush sparrow (Artemisiospiza nevadensis), sage thrasher (Oreoscoptes montanus), greater sage-grouse (Centrocercus urophasianus), pronghorn (Antilocapra americana) and greater short-horned...

The values in this raster are unit-less scores ranging from 0 to 1 that represent normalized dollars per acre damage claims from mule deer on Wyoming lands. This raster is one of 9 inputs used to calculate the "Normalized Importance Index."

In 2002, Rocky Mountain Bird Observatory (RMBO), in cooperation with Bureau of Land Management, U.S. Forest Service, Wyoming Game and Fish Department, and the Wyoming Partners In Flight group, implemented a long-term, habitat-based bird monitoring program designed to provide rigorous population trend data on most diurnal, regularly occurring breeding bird species in Wyoming (Leukering et al. 2001). Modeled after Monitoring Colorado’s Birds (Leukering et al. 2000), this program is entitled Monitoring Wyoming’s Birds (MWB). Monitoring Wyoming’s Birds is consistent with goals emphasized in the Partners In Flight National Landbird Monitoring Strategy (Bart et al. 2001) and, in addition to monitoring bird populations,...

There are an estimated 28,000 mule deer in the upper Green River Basin (i.e., Sublette Herd, Wyoming Game and Fish Department [WGFD] 2006), most of which annually migrate 40 to 100 miles to summer in portions of 5 mountain ranges (Sawyer et al. 2005). Accordingly, successful management of this deer herd will require that functional migration routes remain intact. Given the increased levels of both energy (Bureau of Land Management [BLM] 2005) and housing (Taylor and Lieske 2002) development in Sublette County, identifying and conserving migration routes has become increasingly important. Currently, migration routes are depicted by simply connecting the dots between locations of marked animals (e.g., Sawyer et...

The Northern Goshawk (Accipiter gentilis, Linnaeus 1758) is a diurnal raptor (Family Accipitridae) of temperate forests and woodlands. The genus Accipiter is representative of closely related hawks noted for long tails and relatively broad wings, well suited for pursuit of prey in dense forests. Once commonly known as “bird hawks”, (Craighead and Craighead 1956) the genus is well known for aerial pursuit of avian prey, however, the diet of accipiters is very diverse. Reliant upon explosive acceleration and adept maneuverability, the Northern Goshawk is a predator of birds and small mammals throughout its range. The species has proven to be highly influenced by cyclical abundances of prey species in any...

Pocket gophers are small, vole-like members of the family Geomyidae. They inhabit much of the western half of the United States, a large area of southwestern Canada, and much of Mexico (Bailey 1915). They are powerfully built mammals that are strongly adapted to fossorial living, with small ears, small eyes, fur-lined cheek pouches used to carry food, and very strong front limbs with long nails used for digging. There are several species of pocket gophers in Wyoming and the surrounding states. All look very similar, making it difficult to distinguish specimens to species. Reliable identification has to involve chromosomal analysis (i.e., karyotyping to count chromosome number), with supporting information from geographic...

Given that 95% of the mule deer that winter in the Atlantic Rim Project Area (ARPA) are migratory (Sawyer 2007), sustaining current mule deer populations will require functional migration routes remain intact. Prior to 2000, conserving migration routes had not been a top management concern for agencies because there had been no large‐scale habitat alterations in the ARPA or Baggs Herd Unit, (e.g., Bureau of Land Management [BLM] 2000a, BLM 2000b) and the landscape had remained relatively unchanged. However, the recent approval to develop 2,000 gas wells at a spacing of 8 per section and improve or construct approximately 1,000 miles of road and pipeline (BLM 2006) will result in large‐scale habitat changes that...

The Great Basin spadefoot toad (Spea intermontana) is currently recognized by the Canadian government as a threatened species. In addition, some state agencies throughout its range recognize S. intermontana as a sensitive species, often because too little is known about it to provide evaluations on population status and viability throughout its range. In the last couple of decades, amphibians around the world have experienced population decline, range reduction, and even extinction. This observed trend has been attributed to habitat degradation and loss, chemical pollution, acid precipitation, increased ultraviolet radiation, introduced species, and pathogens, which all combine with the natural fluctuation...

Pocket gophers are members of the family Geomyidae, species of which inhabit virtually all of the United States, a large area of southwestern Canada, and much of Mexico. They are powerfully built mammals that are strongly adapted to fossorial living, with small ears, small eyes, fur-lined cheek pouches used to carry food, and very strong front limbs with long nails used for digging. Although considered pests in some agricultural situations, pocket gophers are important in soil development (incorporating organic matter), soil aeration, and promoting water storage in soil during spring runoff. The Wyoming pocket gopher (Thomomys clusius) is the only vertebrate animal that occurs exclusively in Wyoming; its...

This data set defines boundaries of oil and gas project areas, greater sage-grouse (Centrocercus urophasianus) core areas, and non-core and non-project areas within the Wyoming Landscape Conservation Initiative (WLCI; southwestern Wyoming). Specifically , the data represents results from the manuscript “Combined influences of future oil and gas development and climate on potential Sage-grouse declines and redistribution” for medium oil and gas development, high population size, and no climate component. The oil and gas development scenario were based on an energy footprint model that simulates well, pad, and road patterns for oil and gas recovery options that vary in well types (vertical and directional) and number...
