This layer represents areas which have been proposed (per the requirements of Section 368 of the Energy Policy Act of 2005) as West-wide energy corridors for the final "Programmatic Environmental Impact Statement, Designation of Energy Corridors on Federal Land in the 11 Western States", November 2008. The layer was intersected with surface management agency, BLM field office, and state layers to add more tabular attributes.

The Great Plains Landscape Conservation Cooperative (GPLCC, https://www.fws.gov/science/catalog) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support...

This mapping documents the changes in extent and condition of vernal pool habitat in the Great Valley between 2005 and 2012. "Vernal pool habitat" is defined as vernal pools and the surrounding upland (typically grassland) habitat matrix. The 2005 basemap was created by using double-blind mapping protocol and included 21.4 million acres in and surrounding the Sacramento and San Joaquin valleys (Witham et al 2013). The area included in the 2012 remapping effort focused on the 807,820 acres identified in the 2005 map and areas immediately surrounding the previously mapped polygons. Special attention was paid to areas where habitat was being created through mitigation banking. The result of the 2012 remapping shows...

This data shows select streamgage locations throughout the Red River of the North Basin upstream of Emerson, Manitoba, and basin outlines for eight subbasins..
Since 2008, over 1,400 quadrats and about 2,500 mussels have been systematically sampled within West Newton Chute (WNC), contributing to a diverse assemblage of 25 live species, including 2 federally endangered species, and 10 Minnesota listed species. West Newton Chute is a 2.4 km long side channel in Navigation Pool 5 of the Upper Mississippi River and has an overall aquatic area of ~75 ha. The Minnesota Department of Natural Resources has been quantitatively sampling a mussel bed here (~650 meters long X 170 meters wide) annually since 2008. About 200 systematically-placed 0.25 m2 quads are sampled annually and the quads are spaced ~25 m apart. Briefly, divers excavate substrates to a depth of ~15 cm and place...

About 280 kilometers of multichannel (common-depth-point) seismic reflection profiles were obtained in the central Mississippi River Valley by Geophysical Service Inc. and Western Geophysical Company under contracts with the U.S. Geological Survey. The specific area of the profiles is southeastern Missouri, northeastern Arkansas, and northwestern Tennessee. Geologically, the area is located in the northern part of the Mississippi Embayment.

The data contained in this file is one of several datasets produced in support of the project entitled “Classification and Mapping of Cave and Karst Resources” for the region encompassing the Appalachian Landscape Conservation Cooperative (LCC). The results of this project are divided into a series of geospatial information layers (shapefiles and raster data). The files provide a comprehensive overview of data availability on obligate cave-dwelling fauna and bat ranges useful for examining relationships between environmental factors and biological diversity and distribution within karst areas of the Appalachian LCC.

This layer represents lines which have been proposed (per the requirements of Section 368 of the Energy Policy Act of 2005) as West-wide energy corridor centerlines for the final "Programmatic Environmental Impact Statement, Designation of Energy Corridors on Federal Land in the 11 Western States", November 2008.

This shape file represents an ecological boundary for the Crown of the Continent Ecosystem (CCE) as defined by the Crown Managers Partnership (CMP). The CMP developed the boundary through a series of meetings held in 2008, including a meeting between the CMP and non government organizations working in the Crown on July 23, 2008. The purpose of this exercise was to develop an ecological justification for the CCE, to enable analysis and tracking of the ecosystem from an ecological health perspective. The CMP notes that this extent does not represent the true economic, social and cultural impact on the CCE from surrounding urban areas. In Alberta the eastern boundary was delineated by the Foothills Fescue Subregion...

The Surface Water Drainages, Orders 4 - 7 coverage was derived from a 30-meter resolution elevation grid obtained from the United States Geological Survey (USGS) National Map Viewer website (http://viewer.nationalmap.gov/viewer/) for the extent of interest. Sinks in the elevation data were filled, and the modified elevation grid was then used to create a flow direction and flow accumulation grid. The Strahler drainage network is extracted from the resulting two grids. Extraction was simplified through the use of an ESRI Avenue script known as "Basin1" available for download from the ESRI ArcSripts forum http://arcscripts.esri.com/details.asp?dbid=10668) . The network was generated by the Arizona Department of Environmental...

This child item dataset contains a shapefile representing water quality observations made with a multi-parameter sonde during the 2018 survey, and includes measurements of water temperature, turbidity, pH, dissolved oxygen, and specific conductance along transects of the Old Erie Canal. This data release contains spatial datasets of bathymetry, water velocity, water quality, and infrastructure of a 30.8 mile reach of the Old Erie Canal between the Town of DeWitt and its junction with the current Erie Canal of the New York State Canal System in Verona, near Rome, New York during 2018 and 2019.

These ArcView shapefiles contain representations of numerous themes associated with the Hanna coal zones in the Hanna coalfield, Hanna Basin, Wyoming. The purpose of these shapefiles is to allow the user to perform multiple theme queries. These shapefiles were created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.
