The Prairie Pothole Region spans parts of North and South Dakota, Minnesota, Montana, Iowa and south-central Canada and contains millions of wetlands that provide habitat for breeding and migrating birds. Because it is the continent’s most important breeding area for waterfowl, conservation and management largely focuses on protecting habitat for nesting ducks. However, other wetland-dependent birds also rely on this region, and it is important to understand the degree to which habitat conserved for ducks provides habitat for other species, and how the quality of this habitat will be affected by climate change. Project researchers will test whether waterfowl are effective representatives, or surrogates, for other...
This dataset presents measures of landscape fragmentation calculated by FRAGSTATS at 4KM and HUC5 reporting unit levels. Fragmentation integrates the influence of urban, agriculture, invasive vegetation, roads, pipelines, utility lines, oil/gas wells, and water on patches of natural vegetation.
This map shows the current and historic distribution of this ecosystem, in the context of change agents and disturbance types, as well as current and near-term status and long term potential for change. This map includes current distribution from LANDFIRE EVT and NatureServe Landcover, and historic distribution from LANDFIRE BpS.

This map shows the potential current distribution of yellow-breasted chat, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.
This map shows the location of EPA Level IV Ecoregions in the Colorado Plateau Ecoregion.
This map shows the current distribution of this ecosystem (from NatureServe Landcover), in the context of current and near-term status and long term potential for change.
This map shows the location of sensitive soils, which were extracted from SSURGO and STATSGO soil datasets.

This raster depicts the percentage of lithological aluminum oxide (Al2O3) content in surface or near surface geology. We derived these rasters by calculating the average percent Al2O3 content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater than 100 feet (from...

This collection of maps shows fluvial geomorphic features of the Colorado River bottomland including river channel boundaries at high flow (31,300 cubic ft/sec on 06/28/2011 at the Cisco gage) and at lower flow (3,410 cubic ft/sec on 09/06/2010 at the Cisco gage). Also shown is the bottomland boundary delineating the currently active fluvial surface; the bottomland is subdivided by both reaches and bottomland kilometers for reference. Centerlines for the bottomland and 2010 river channel are included, also.

This raster depicts the percentage of lithological magnesium oxide (MgO) content in surface or near surface geology. We derived these rasters by calculating the average percent MgO content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep.

High-latitude regions are experiencing rapid and extensive changes in ecosystem composition and function as the result of increases in average air temperature. Increasing air temperatures have led to widespread thawing and degradation of permafrost, which in turn has affected ecosystems, socioeconomics, and the carbon cycle of high latitudes. Research shows that the distribution of permafrost is heterogeneous in nature and that permafrost responds to a wide range of ecological factors. Here we overcome complex interactions between surface and subsurface conditions to map near-surface permafrost using decision-tree models, field observations, remotely sensed and derived data, and climatic indices. The resultant dataset...

BISON is an information system that allows users to access, explore, map and download U.S. species occurrence data from participating data providers. BISON aggregates and provides access to standardized diverse sources of species occurrence data integrated with other non-biological data layers. Server independent APIs allow direct access to data. http://bison.usgs.ornl.gov/ BISON@usgs.gov
