GAP Land Cover Viewer The Gap Analysis Program (GAP) Land Cover Viewer displays data on the vegetation and land use patterns of the continental United States. The GAP Land Cover Data Version 2.2 provides detailed information on the vegetation of the United States using consistent satellite base data and classification systems. This allows data users to make conservation or land use planning decisions for the entire range of a habitat type across administrative boundaries. GAP Land Cover Data Version 2.2 combines ecological system data from previous GAP projects in the Southwest, Southeast, and Northwest United States with recently updated California data. For Alaska ,and areas of the continental United States, where ecological system-level...

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 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...

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.

Geology, Fewer tags Southeast Regional Assessment Project (SERAP): Assessing Global Change Impacts on Natural and Human Systems in the Southeast The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. 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...
