The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity 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...

This collection of maps shows relative habitat quality for a suite of species that use riparian overstory habitats. Component layers include: tree patch size, presence and complexity of riparian understory, and abundance of tamarisk. Associated layers such as river channels at high flow and bottomland reaches are included for reference.

This data layer summarizes ecological systems and land cover classes described in state-level and national-level maps as Broadly Defined Habitats for groups of species of conservation concern. Each grid cell in the raster is assigned a Condition Index value based on desired condition metrics using ancillary datasets and a decision tree approach for each assessed habitat. Grid cells are also assigned bar code descriptors indicating which metrics contributed to the Condition Index score for that cell. This layer also contains information about potential habitats based on the LANDFIRE Biophysical Settings data layer. This layer was developed to support the next iteration of the Conservation Blueprint developed by the...

Current national data resources for GAP include three primary data sets – land cover, protected areas, and species. Land Cover: The GAP/LANDFIRE National Terrestrial Ecosystems data, based on the NatureServe Ecological Systems Classification, are the foundation of the most detailed, consistent map of vegetation available for the United States. These data facilitate the planning and management for biological diversity on a regional and national scale. Learn more about GAP land cover data here: https://www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/land-cover Protected Areas: The Protected Areas Database of the United States (PAD-US) is a national geodatabase, created by USGS GAP,...

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 the compressive strength, measured as uniaxial compressive strength (in megaPascals, MPa) of surface or near surface geology. We derived these rasters by calculating the average strength for each map unit in combined surficial-bedrock geologic maps.

The Gap Analysis Program's (GAP) Species Viewer allows users to explore, download, and create maps of vertebrate species ranges and models developed by GAP. The Viewer displays data on vertebrate species ranges and distribution models for the continental U.S. as well as Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. More specifically, species distribution models based on deductive modeling of habitat associations are displayed across entire species ranges for over 2000 species. The goal is to build species range maps and distribution models with the best available data for assessing conservation status, conservation planning, and research (e.g., climate change impacts). Ranges are represented by 12-digit...
