The Southwest Biological Science Center (SBSC) is "the newest of the 17 science centers that are part of the U.S. Geological Survey's Biological Resources Discipline." Research at the SBSC "includes water use and the effects of livestock grazing, wild land fires, invasive species, environmental contaminants, declining populations of native species, and urban development on the Southwest region." The four main research stations that operate under the auspices of the SBSC include the Canyonlands Research Station, Colorado Plateau Research Station, Grand Canyon Monitoring & Research Station, and Sonoran Desert Research Station. In addition to links to the different research station sites, the SBSC site contains contact information for its many staff members, and a Products Database with nearly 1,500 references for technical reports, journal articles, book chapters, webpages, and more. A number of the documents are available in PDF. Note: Sections of the website are still under development, and SBSC should be offering more information about its research activities in the future.
