Gap Analysis Program (GAP)

The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

A GAP Analysis uses GIS layers provided by the GAP Analysis Program (species distribution models, stewardship data) to determine which areas within a species distribution have protected status and to identify possible conservation gaps. This GAP Analysis was conducted for Greater Sage-grouse within the boundary of the Southern Rockies LCC. About 7.6% of the Sage-grouse's total predicted distribution is within the SRLCC (based on GAP distribution models). There are four products in this ScienceBase item: an Excel spreadsheet with analysis data (see list below), a GIF image map of the SRLCC (displaying predicted sage-grouse distribution and areas with protected status), a map package containing the GIS layers used...

The USGS GAP land cover data, clipped to the boundary of the Southern Rockies LCC. All 5 levels of the National Vegetation Classification (NVC) system can be displayed in the map package. There is also an attached report from the GAP Land Cover Viewer, showing land cover areas (hectares and square miles) in the SRLCC and each category's percent of the total SRLCC area. From attached metadata: "This dataset combines the work of several different projects to create a seamless data set for the contiguous United States. Data from four regional Gap Analysis Projects and the LANDFIRE project were combined to make this dataset. In the Northwestern United States (Idaho, Oregon, Montana, Washington and Wyoming) data in...
From http://gapanalysis.usgs.gov/species/: "GAP's Species data includes vertebrate range maps and distribution models for amphibians, birds, mammals, and reptiles occurring in the U.S. These kinds of maps and data are fundamental to conservation planning, forecasting (e.g., climate change), and research." Download data (http://gapanalysis.usgs.gov/species/data/download/), view data in the GAP Species Viewer (http://gapanalysis.usgs.gov/species/viewer/) or access web services (http://gapanalysis.usgs.gov/species/data/web-map-services/)

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
