This network of inland streams, wetlands and water bodies is a composite of two layers from the National Hydrography Dataset Plus (NHD+ flow lines and water bodies), and all available wetlands from the National Wetlands Inventory (NWI) and Wisconsin Wetlands Inventory (WWI). In combination, these layers provide a network template of inland corridors for assessing relative vulnerability to future invasions of Phragmites.

The Energy Release Component (ERC) is a calculated output of the National Fire Danger Rating System (NFDRS). The ERC is a number related to the available energy (BTU) per unit area (square foot) within the flaming front at the head of a fire. The ERC is considered a composite fuel moisture index as it reflects the contribution of all live and dead fuels to potential fire intensity. As live fuels cure and dead fuels dry, the ERC will increase and can be described as a build-up index. The ERC has memory. Each daily calculation considers the past 7 days in calculating the new number. Daily variations of the ERC are relatively small as wind is not part of the calculation. The ERC is projected to the 2050s using three...

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...

This raster depicts the percentage of lithological phosphorus pentoxide (P2O5) content in surface or near surface geology. We derived these rasters by calculating the average percent P2O5 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...

These data represent coastal corridors exposed by lake levels reduced from mean 2009 water surface elevations. These elevations were established by values published by the United States Army Corps of Engineers (USACE), and based on a network of multiple gages within each lake. The corridors were derived from two data sources: 5-m resolution lidar-based topo-bathymetry produced by the USACE Joint Airborne Lidar-Based Technical Center of eXpertise (JALBTCX) and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, and bathymetric contour lines produced by the NOAA Great Lakes Environmental Research Laboratory (GLERL). The JALBTCX lidar-based topo-bathymetry were used to produce representations...

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 map shows current and near-term terrestrial intactness, as well as long term potential for development and climate change. These datasets are the results of a series of fuzzy logic models that integrate many landscape factors, including urban, agriculture, roads, invasive vegetation, and fire regime.

A team of USGS and academic researchers developed a comprehensive web-based dataset of high-resolution (or ‘downscaled’) climate change projections, enabling scientists and decision-makers to better assess climate related ecosystem impacts. The research team implemented a three-part plan to provide high resolution climate data for the impact modeling community. First, a database was developed of up-to-date and state-of-the-art downscaled climate projections for the U.S., using a range of plausible future greenhouse gas emission scenarios. Second, a series of workshops were held to solicit input about climate-related data needs and to discuss best practices for accessing and using downscaled climate projections....

The broad range of complex factors influencing coastal systems contribute to large uncertainties in predicting long-term sea level rise impacts. Researchers demonstrated the capabilities of a Bayesian network (BN) to predict long-term shoreline change associated with sea level rise and make quantitative assessments for predicting uncertainty. A BN was used to define relationships between driving forces, geologic constraints, and coastal response for the U.S. Atlantic coast that include observations of local rates of relative sea level rise, wave height, tide range, geomorphic classification, coastal slope, and shoreline change rate. The BN was used to make probabilistic predictions of shoreline retreat in response...
