Jasper Ridge Biological Preserve (original) (raw)

The Jasper Ridge Biological Preserve is a 483 hectares (1,190 acres) nature preserve and biological field station formally established as a reserve in 1973. The biological preserve is owned by Stanford University, and is located at 37°24′29″N 122°13′39″W / 37.408°N 122.2275°W south of Sand Hill Road and west of Interstate 280 in Portola Valley, San Mateo County, California. It is used by students, researchers, and docents to conduct biology research, and teach the community about the importance of that research. The preserve encompasses Jasper Ridge and Searsville Lake (actually a reservoir) and the upper reaches of San Francisquito Creek, along with the latter's Corte Madera Creek and Bear Creek tributaries.
