This raster depicts the percentage of lithological aluminum oxide (Al2O3) content in surface or near surface geology. We derived these rasters by calculating the average percent Al2O3 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...

This set of maps shows relative habitat quality for riparian understory species, both with and without a penalty applied for abundant tamarisk. Component layers are included, as are complementary layers of channel boundaries, reaches, and bottomland kilometers.

This map shows the potential current distribution of Burrowing Owl, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.
thumbnail
This map shows fire regime departure estimates for the ecoregion, including measures of departure for fire severity and frequency in addition to existing measures of vegetation departure.
This map provides an estimate of current and near-term aquatic intactness, which is based on the results of a fuzzy logic model integrating land use, water quality, hydrologic impacts, and road impacts. It also shows long-term potential for climate change.

This map shows the location of terrestrial biodiversity sites, which are mapped by The Nature Conservancy's Conservation Portfolio areas.

This map shows the potential current distribution of Gunnison's prairie dog, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.
This map shows potential areas of aquatic biodiversity. Based on protected and conservation lands superimposed on the NHD flowlines dataset.

This raster depicts the percentage of lithological sulfur (S) content in surface or near surface geology. We derived these rasters by calculating the average percent S 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 Soller et al....

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

This map shows areas where fire may potentially be adverse to ecological communities. These areas are based on systems with historically longer fire frequency where invasive vegetation or uncharacteristic native vegetation occur.
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.
