Rocky Mountain Region GIS Data Library Our geographic area of responsibility covers Colorado, Kansas, Nebraska, South Dakota, and Wyoming.
Montana/Dakotas BLM changed from a 'three-tier' organization (state office/district office/resource area office) to a 'two-tier' organization (state office/field office) several years ago. These data reflect the new 'two-tier' organization. These data depict Bureau of Land Management (BLM) administrative units (Field Office boundaries) in Montana. The attribute data include the name and contact information for each Field Office.
This is an ESRI personal geodatabase containing the Channel Migration Zone (CMZ) developed for the Yellowstone River. The CMZ extends from Gardiner, Montana to the River's confluence with the Missouri River in McKenzie County, North Dakota. Also included are the various datasets used in the development of the CMZ, such as geology designations and channel migration vectors.

A species distribution model for guiding Oregon spotted frog (Rana pretiosa) surveys near the southern extent of its geographic range
T he Oregon spotted frog (Rana pretiosa), endemic to the Pacific Northwest, was once considered widespread in complex, warm water wetlands. Over 70% of historic populations are thought to be extirpated with range-wide habitat loss exceeding 90%. Using Maxent, I developed a series of Species Distribution Models (SDMs) to identify suitable habitat and predict the distribution of Rana pretiosa toward the southern extent of its geographic range. These SDMs were generated from two sets of spatial data: a set of occurrence points and a suite of environmental variables. Occurrence data included all verified populations within the study area. Environmental variables, used to characterize habitat associated with recognized...
This GIS dataset is part of a suite of wildlife habitat connectivity data produced by the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The WHCWG is a voluntary public-private partnership between state and federal agencies, universities, tribes, and non-governmental organizations. The WHCWG is co-led by the Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Transportation (WSDOT). This dataset quantifies current wildlife habitat connectivity patterns for the Columbia Plateau Ecoregion in Washington, Oregon, and Idaho. Available WHCWG raster data include model base layers, resistance, habitat, cost-weighted distance, and landscape integrity. Grid cell size is 90 m...
This map service contains GIS data in Web Mercator from the EPA Office of Water for the National Hydrography Dataset (NHD) integrated with reach-related information from the USEPA Reach File Version 3.0-Alpha release (RF3-Alpha). This service also includes hydrographic landmark features in NHD. It is available as a WMS, KML, and REST service as well as the native MapServer service.
