FY2011Research is showing that populations of wintering raptors, including Northern Harriers, Rough-Legged Hawks, Prairie Falcons, American Kestrels. Red-Tailed Hawks and Golden Eagles, have stayed relatively constant in the last 20 years are being used by the Bureau of Land Management and Idaho Army National Guard in developing raptor conservation management practices. The American Wind and WildlifeInstitute will also use the results for their wind energy siting support tools.
This set of 4 rasters shows winter (Dec to Feb) mean temperature (deg C * 10) for Western North America under the A1B Emissions Scenario from the Intergovernmental Panel on Climate Change (IPCC). One layer shows the historic period (1961 to 1990), and there are three layers of future climate projections representing the 2020s, the 2050s, and the 2080s. These future layers are ensemble averages across all 23 CMIP3 AOGCMs (Coupled Model Intercomparison Project 3 Atmosphere-Ocean General Circulation Models). All layers have a resolution of 1 km, and are designed to capture climate gradients, temperature inversions, and rain shadows in the mountainous landscape of western North America. These data, originally published...

There is widespread evidence that multiple drivers of global change, such as habitat degradation, invasive species, and climate change, are influencing wildlife. Understanding how these drivers interact with and affect species may be difficult because outcomes depend on the magnitude and duration of environmental change and the life history of the organism. In addition, various environmental drivers may be evaluated and managed at different spatial scales. We used a historical dataset from 1991 to 1994 and current information from 2010 to 2012 to examine whether occupancy patterns of wintering raptors were consistent with regional changes in distribution or habitat conditions within a local management unit, the...
With shortening snow season duration, snowshoe hares are experiencing increased camouflage mismatch with their environment reducing survival. Phenological variation of hare molt at regional scales could facilitate local adaptation in the face of climate change, but the level of variation, especially along the southern range boundary, is unknown. Using a network of trail cameras and historical museum specimens, we (1) developed contemporary and historical molt phenology curves in the Upper Great Lakes region, USA.
This set of 4 rasters shows winter (Dec to Feb) mean temperature (deg C * 10) for Western North America under the B1 Emissions Scenario from the Intergovernmental Panel on Climate Change (IPCC). One layer shows the historic period (1961 to 1990), and there are three layers of future climate projections representing the 2020s, the 2050s, and the 2080s.

This data set represents the Wildlife Habitat Management Area boundaries. The Wyoming Game and Fish Department, under the direction of the Wyoming Game and Fish Commission, administers lands and public easement areas that are home to vast numbers of fish and wildlife. The department maintains approximately 413,000 acres of land under deed, lease or by agreement and continually strives to acquire new access areas. These areas include access to nearly 225 miles of streams, over 21,000 lake surface areas, and more than 148 miles of road right-of-ways. Management of these lands demonstrates our state's commitment to its precious wildlife heritage and those people who seek to enjoy our wildlife and wild lands. Wyoming's...
This is an ArcGIS shapefile which depicts the seasonal salinity dynamics of 32 Gulf of Mexico estuaries. To characterize the dynamic nature of estuarine salinity gradients, a multivariate methodology (Bulger et al. 1993) was applied to derive five bio-salinity zones in four salinity seasons for 32 Gulf of Mexico estuaries (Christensen et al. 1997). This seasonal salinity zone spatial framework built upon and refined earlier studies which characterized salinity on an annual-averaged basis (NOAA 1985, Orlando et al. 1993, NOAA 2007). Precipitation, flow gage data, and monthly salinity averages were evaluated to determine which months would be used to represent the high, low, and transitional (increasing and decreasing)...

The tabular dataset is a compilation of all historic observations of whooping crane locations up through 1941. Most of the records were obtained from Robert Porter Allen's 1952 report, "The Whooping Crane"; an additional 73 records were added from records found since 1952. Records include source (Allen 1952 [The Whooping Crane, Audubon]or other), location name, county, state or province, country (Canada, US, Mexico), estimated latitude and longitude, year, month, day, life stage (breeding, summering, wintering, migration, unknown), season (spring, summer, fall, winter), observer's name, and logical indicators of nesting, specimen taken, observer identified, or if captive bird. Completeness of each record is variable....

This dataset provides the winter bird transect survey data collected on seven sites in southeastern Arizona during the winters (January - March) of 1999-2001; and for two of those seven sites during the winters of 2003-2005.
In order to understand ongoing and future climate change and its impacts on ecosystem services, we must have a grasp on historical ranges of climate variability. Fortunately, detailed weather station data are available in the United States for thousands of locations over the last century. Moreover, sophisticated approaches have been developed for translating these measurements into unified datasets across the U.S., including climate estimates for locations that lack station data.The PRISM (Parameter-elevation Regressions on Independent Slopes Model) Climate Group produces such estimates from weather station data at daily, monthly, and annual time steps, incorporating data from 1895 to the present day. PRISM methods...

Studies of multiple taxa across broad-scales suggest that species distributions are shifting poleward in response to global climate change. Recognizing the influence of distribution shifts on population indices will be an important part of interpreting trends within management units because current practice often assumes that changes in local populations reflect local habitat conditions. However, the individual- and population-level processes that drive distribution shifts may occur across a large, regional scale and have little to do with the habitats within the management unit. We examined the latitudinal center of abundance for the winter distributions of six western North America raptor species using Christmas...
