GAP/LANDFIRE National Terrestrial Ecosystems 2011 Map Viewer

The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program.  The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.

National Biogeographic Map

The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.

Through a Fish's Eye: The Status of Fish Habitats in the United States 2015

This report summarizes the results of an unprecedented nationwide assessment of human effects on fish habitat in the rivers and estuaries of the United States.  The assessment assigns a risk of current habitat degradation scores for watersheds and estuaries across the nation and within 14 sub-regions.  The results also identify some of the major sources of habitat degradation.

National Fish Habitat Partnership (NFHP) 2015 Anthropogenic Disturbance Data for Southeast Alaska With Link to the Modified NHD with Catchments v1.1

This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within local and network stream catchments of Southeast Alaska. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (...

First Comprehensive List of Non-native Species Established in Three Major Regions of the United States

Invasive species are a subset of non-native (or alien) species, and knowing what species are non-native to a region is a first step to managing invasive species. People have been compiling non-native and invasive species lists ever since these species started causing harm, yet national non-native species lists are neither universal, nor common. Non-native species lists serve diverse purposes:...

U.S. Geological Survey - Gap Analysis Project Species Habitat Maps CONUS_2001

Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not...

U.S. Geological Survey - Gap Analysis Project Species Range Maps CONUS_2001

GAP species range data are coarse representations of the total areal extent a species occupies, in other words the geographic limits within which a species can be found (Morrison and Hall 2002). These data provide the geographic extent within which the USGS Gap Analysis Project delineates areas of suitable habitat for terrestrial vertebrate species in their species habitat maps. The range maps...

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Special Features Points

The Central Mojave Special Features shapefile provides point locations for known or potential places where vegetation alliances or unique stands occurred (from 1997-1999) with less than 5 hectares of spatial extent. These designations were provided separately from the Mojave Vegetation Polygons because the target standard for the polygons was a minimum mapping unit (MMU) of 5 hectares, thus...
