Mule deer in the Sheep Creek sub herd are part of the larger Area 6 herd that occupies portions of Elko, Lander, and Eureka counties. The primary winter range of this population is located along the eastern flank of the Sheep Creek Range and the west side of Boulder Valley. Most deer migrate approximately 30 miles from winter ranges in upper Boulder Creek and Antelope Creek drainages to summer ranges on the west side of the Tuscarora Mountains. However, some deer in this population migrate much farther – approximately 80 miles – and connect with mule deer that summer east of the Humboldt River. This deer herd faces several challenges, including migration routes that pass through increased mineral extraction activities...

The Mojave Plots Points data are 1,219 plot locations in the Central Mojave Desert where field data were recorded and repeat photographs were taken from 1997-1999 to provide context for the classification of the Central Mojave Desert into various vegetation classes. The 1,219 plot locations in the plots points shapefile (plots_points.shp) are each assigned a unique identifier called the FinalPlotCode. The FinalPlotCode can be used to match the shapefile points to the Mojave Field Data. The attached CSV file (Mojave_Images_Crosswalk.csv) can be used to relate the FinalPlotCodes to the associated repeat photographs that are attached as zipped TIFF images to the ScienceBase page. There are 1,695 total repeat photographs...

Rocky Mountain Research Station scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. By re-measuring vegetation and bird populations following wildfires and applying climate change models, they will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing resilient forests and conserving the avian community structure. They will also continue and expand citizen science efforts to develop a long term avian monitoring plan, as well as simulation studies to provide optimal monitoring designs for avian species to detect changes from large-scale stressors.

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of occupied Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus) habitat to climate change for each 12-digit hydrologic unit. Cutthroat trout occupied habitat was mapped from the range-wide status report (Hirsch et. al 2013). Using a vulnerability framework, we defined Sensitivity (S) as the total length of occupied cutthroat trout habitat within HUC12 polygons. The exposure parameter incorporates two climate change metrics, the change in flow timing and change in stream temperature. Exposure is quantified as the square root transformed product of the two climate change metrics. Potential Impact...

Critical habitat polygons - Mississippi River BasinWhen a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An...
This sampling frame is a set of grid-based finite-area frames spanning Canada, the United States, and Mexico. The grid for the United States is broken into individual grids for the continental United States, Hawaii, and Puerto Rico. Alaska is combined with Canada into a single grid. Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency “Bat Grid” monitoring program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat)....

This is the input data associated with the project: “Status and Trends of Deciduous Communities in the Bighorn Mountains”. The aim of the study is to assess the current trends of deciduous communities in the Bighorn National Forest in north-central Wyoming. The data here represents phase I of the project, completed in FY2017. The USGS created a synthesis map of coniferous and deciduous communities in the Bighorn Mountains of Wyoming using a species distribution modeling approach developed in the Wyoming Landscape Conservation Initiative (WLCI) (Assal et al. 2015). The modeling framework utilized a number of topographic covariates and temporal remote sensing data from the early, mid and late growing season to capitalize...

This dataset represents vegetation communities, river channel and bare areas (often sand bars) mapped along the Colorado River bottomland in Utah, as of September 2010. Dominant cover types were classified as 'open flight', based on height, and potential interference with bat flights over water sources. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow, from high resolution, true color, aerial imagery (0.3m resolution), acquired for the project. Additional, public available aerial photos (NAIP, 2011) were used to cross-reference cover classes. As with any digital layer, this layer is a representation of what is actually occurring...

This is a habitat suitability model riparian understory species in the Colorado River bottomland in Utah. The model incorporates the density of shrubs, the number of shrub species present, and the stillness of adjacent water. A penalty value is applied to represent tamarisk abundance as a potential risk to habitat quality.
