Geochemical Characteristics of the Conterminous United States: % CaO This raster depicts the percentage of lithological calcium oxide (CaO) content in surface or near surface geology. We derived these rasters by calculating the average percent CaO 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 map shows least-cost corridors and large natural habitat blocks. These blocks and corridors may provide an essential network for various species to disperse through the landscape. Blocks are based on large areas of contiguous natural vegetation cover, and are subdivided by major roads. We connected blocks using sticks (to define a pair of blocks between which to model corridors), and developed least-cost corridors based on a cost surface developed from land cover.

The U.S. Geological Survey's BISON (Biodiversity Information Serving Our Nation - https://bison.usgs.gov) application is a product of the USGS Science, Analytics and Synthesis Program. BISON is an information system that allows users to access, explore, and download species occurrence data (predominantly specimen-based e.g. from digitized museum...

Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers and conservation planners can be effective at preserving ecosystems in the face of these stressors only if they can adapt current conservation efforts to increase the overall resilience of the system. Climate change, in particular, challenges many of the basic assumptions used by conservation planners and managers. Previous conservation...
