When a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area is designated as “critical habitat” after the...

This map layer portrays the major roads in the United States, Puerto Rico, and the U.S. Virgin Islands. The file was produced by joining the individual State roads layers from the National Highway Planning Network (NHPN), Geographic Data Technology (GDT) Dynamap, and TIGER/Line files. This is a revised version of the July 2012 map layer.

This map layer portrays the coastline of the United States, Puerto Rico, and the U.S. Virgin Islands. The United States shoreline of the Great Lakes is also included. This is a revised version of the July 2012 map layer.
This map layer portrays the State boundaries of the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was created by extracting county polygon features from the CENSUS 2006 TIGER/Line files produced by the U.S. Census Bureau. These files were then merged into a single file and county boundaries within States were removed. This is a revised version of the July 2012 map layer.

This map layer shows elevation contour lines for Puerto Rico and the U.S. Virgin Islands. The map layer was derived from the 100-meter resolution elevation data set which is published by the National Atlas of the United States, and is in the same Albers Equal-area Conic projection as that source data set. Contour intervals match the steps used in the National Atlas Color-Sliced Elevation data sets. Contours were adjusted so that they are in the proper relationship to National Atlas 1:1,000,000-scale lakes, reservoirs, and wide (double-line) streams.
This geodatabase contains streams, waterbodies and wetlands, streamflow gaging stations, and coastlines for the United States, Puerto Rico, and the U.S. Virgin Islands. The streams are incorporated into a geometric network. All feature classes are vertically integrated with each other and with 1:1,000,000-scale transportation and boundary data sets.

USGS Small-scale Dataset - 1:1,000,000-Scale County Boundaries of the United States 201403 Shapefile
This map layer portrays the county boundaries of the United States, Puerto Rico, and the U.S. Virgin Islands, by showing the counties as areas. The map layer was created by extracting county polygon features from the CENSUS 2006 TIGER/Line files produced by the U.S. Census Bureau. These files were then merged into a single file. This is a revised version of the July 2012 map layer.

Fish collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 at 58 stations followed by 10 days each in April 2011 and January 2012 surveying poorly sampled shoreline habitats with rotenone and clove oil and inland streams with seine.

This map layer portrays the county boundaries of the United States, Puerto Rico, and the U.S. Virgin Islands as linework. The map layer was derived from the 1:1,000,000-Scale County Boundaries of the United States polygon data set by applying the Arc/Info Clean function. The Clean function eliminates the duplicate arcs present in polygon shapefiles, leaving one copy of each line.
