NOTE: A newer online map viewer for the Protected Areas Database of the United States (PAD-US) is available: https://maps.usgs.gov/padusdataexplorer 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...

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 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...

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with...

NOTE: A more current version of the Protected Areas Database of the United States (PAD-US) is available: PAD-US 2.1 https://doi.org/10.5066/P92QM3NT. The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme (https://communities.geoplatform.gov/ngda-cadastre/). The PAD-US is an ongoing project with several published versions of a spatial database including areas dedicated to the preservation of biological diversity, and other natural (including extraction), recreational, or cultural uses, managed for these purposes...

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 included in the map are those predicted to be unsuitable for the species. While the actual distributions of many species are likely to be habitat limited, suitable habitat will not always be occupied because of population dynamics and species interactions. Furthermore, these maps correspond to midscale characterizations of landscapes,...

This raster depicts the percentage of lithological sodium oxide (Na2O) content in surface or near surface geology. We derived these rasters by calculating the average percent Na2O content 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 than 100 feet (from...
