Abstract : The two-year research program, "Biodiversity and Landscape Planning: Alternative Futures for the Region of Camp Pendleton, California," explores how urban growth and change in the rapidly developing area located between San Diego and Los Angeles might influence the biodiversity of the area. The study was conducted by a team of investigators from the Harvard University Graduate School of Design, Utah State University, the National Biological Service, the USDA Forest Service, The Nature Conservancy, and the Biodiversity Research Consortium, with the cooperation of the two relevant regional agencies, the San Diego Association of Governments and the Southern California Association of Governments, and Marine Corps Base Camp Pendleton.
