Jasper Ridge Biological Preserve
The Jasper Ridge Biological Preserve is a 1,200 acre (5 km²) nature preserve and biological field station owned by Stanford University, located at south of Sand Hill Road and west of Interstate 280 in Portola Valley, 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.

Jasper Ridge is part of the foothills northeast of the Santa Cruz Mountains and is bounded by San Francisquito Creek, Corte Madera Creek and Los Trancos Creek, although the preserve occupies only the northwestern half of the ridge. The hilly mass runs about ten kilometers from northwest to southeast and about half that in width.
