All secondary roads in the western United States from the 2000 US Census TIGER/line files. Secondary roads are defined as all roadways not classified as an interstate, state highway, or federal highway.

This roads dataset for Wyoming has been extracted from the U.S. Census TIGER/Line shapefiles (http://www.census.gov/geo/www/tiger) and is avialable here as a statewide dataset. Data for each county was merged to create the statewide dataset. Road data was then extracted from the 'edges' (attribute: roadflg, 'Y') line data by WyGISC. Attributes deemed unecessary were removed by WyGISC. For the original data, visit the tiger data website listed above. The TIGER/Line Shapefiles are an extract of selected geographic and cartographic information from the Census MAF/TIGER database. The Census MAF/TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each TIGER/Line Shapefile...

A polygon dataset of current abandoned railroad footprints in the SNK REA derived from the Alaska Department of Natural Resources infrastructure data (see the process steps for details). (This data depicts infrastructure locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.)
This dataset consists of point features identifying indices for potential passage rate at intersections with major transportation corridors for grizzly bear movements between the Greater Yellowstone Ecosystem (GYE) and Northern Continental Divide Ecosystem (NCDE) in the northwestern United States. Points are spaced at 300-meter intervals along major road corridors (interstates and U.S. highways) and are populated with values from Randomized Shortest Path (RSP) predictive raster models of potential male grizzly bear movement between the two ecosystems as described in Peck et al. 2016 (Potential paths for male-mediated gene flow to and from an isolated grizzly bear population, Ecosphere 8(10):e01969). RSP scores extracted...

A joint venture involving the National Atlas programs in Canada (Natural Resources Canada), Mexico (Instituto Nacional de Estadística y Geografía), and the United States (U.S. Geological Survey), as well as the North American Commission for Environmental Cooperation, has led to the release (June 2004) of several new products: an updated paper map of North America, and its associated geospatial data sets and their metadata. These data sets are available online from each of the partner countries for download. The North American Atlas data are standardized geospatial data sets at 1:10,000,000 scale. A variety of basic data layers (e.g. roads, railroads, populated places, political boundaries, hydrography,...

A polygon dataset of current trails footprints (including ice roads) in the SNK REA derived from the Alaska Department of Natural Resources infrastructure data, Northwest Arctic Burough winter trails data and BLM Iditarod National Historic Trail data (see the process steps for details). (From the Alaska Department of Natural Resource Infrastructure data metadata: This data depicts infrastructure locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles.

Synopsis: The study examined the effects of road networks on suburbanizing ecosystems, using grassland bird distribution to explore the relative ecological importance of variables relative to linear disturbances and the effect of road traffic volumes. The study found that roads primarily affect ecological variables for 1) distance from road and 2) habitat patch size. The study also found that road traffic volumes are correlated to avian distribution, suggesting that traffic volumes have an ecological effect. The research suggests that traffic noise is the primary ecological effect of roads and that roads with higher traffic volumes extend the road effect zone outwards of 100 m and up to 1,200 m. Given the ecological...
