Refuge GAP

Refuge GAP is a decision support system designed to explore biodiversity and ancillary information at National Wildlife Refuges in the State of Wyoming.


The US Geological Survey Gap Analysis Program (GAP) and the Wyoming Gap Analysis program at the University of Wyoming's Spatial Data and Visualization Center developed the Refuge GAP decision support system to assist US Fish and Wildlife Service managers with land prioritization processes. The system uses GAP and other biological data in a desktop GIS environment to show where different species occur, or are predicted to occur, within the state. The user can look at information for a particular site (for impact analyses), an individual wildlife refuge, or information for the entire state. Refuge GAP uses GAP data to look at general and regional patterns and trends for selected species. Refuge GAP's regional analysis module is designed to mirror the U.S. Fish and Wildlife Service's Land Acquisition Priority System for significant community biodiversity targets. This is a four-step process which prompts the user to assign ranks of importance to variables such as significance to biodiversity protection, degree of alteration, management considerations (land use) and species of concern. The user is taken through a series of menus which display data available for input variables and prompts for the input of weights to each of the variables. Once all the variables have been weighted, they are combined in a GIS analytical process, the result of which is a map, color-coded to depict areas which meet the specified criteria for land acquisition.
