This map shows special designations in the ecoregion, derived from the CBI Protected Areas Database, National Conservation Easements Database, Roadless Areas, BLM NLCS Wilderness Areas, and BLM ACECs.
This map shows percent cover of early and late successional soil crusts, and current, near-term, and long-term evaluations of these.

This map shows the potential current distribution of mountain lion, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.

This map shows naturalized flow change for April-July for 3 periods: 1951-1965 (historic), 2016-2030, and 2046-2060 simulated by the Bureau of Reclamation across 112 GCM scenarios.
This map presents summaries of conservation elements by reporting unit (4KM) alongside terrestrial intactness and long-term potential for change. This includes additional dataset focused on non-designated/non-urban lands, and non-designated/non-urban areas on BLM lands.

This map shows potential alluvial aquifers based on sand, gravel, and alluvium types in the surficial geology datasets of Arizona, Colorado, New Mexico, and Utah.

This map shows the potential current distribution of pronghorn antelope, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.

Map of the alluvial valley of the Mississippi River from the head of St. Francis Basin to the Gulf of Mexico, showing lands subject to overflow, location of levees and trans-alluvial profiles Downloaded from: https://www.digitalcommonwealth.org/search/commonwealth:7h14b0450 Edited (to correct position of panels) and georeferenced by Yvonne Allen (USFWS) to geographic NAD1927 using ArcGIS , 3rd order polynomial and 80 ground control points using lat lon grid.

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...

This map shows the current distribution of this ecosystem (from NatureServe Landcover), in the context of current and near-term status and long term potential for change.

This map shows distribution of the Gunnison Sage-Grouse relative to various protected areas.

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.
This map shows the potential current distribution of Colorado River Cutthroat Trout as well as current and near-term status, and long term potential for change (due to climate change).
This map shows the current and historic distribution of this ecosystem, in the context of change agents and disturbance types, as well as current and near-term status and long term potential for change. This map includes current distribution from LANDFIRE EVT and NatureServe Landcover, and historic distribution from LANDFIRE BpS.

This map shows climate parameters and MAPSS biogeography model data for the western US from PRISM (1968-1999), and future climate projections from the regional climate model RegCM3 using ECHAM5, GENMOM, and GFDL projections as boundary conditions for 2015-2030, and 2045-2060.
