The University of California Natural Reserve System is a network of 39 teaching and research sites dispersed across California, protecting more than 756,000 acres of diverse habitats. The Natural Reserve System is the largest university-administered reserve system in the world. UC Davis manages five of the reserves in north-central California, providing secure sites for research, instruction, and public outreach. All UC Davis reserves are available for university-level academic use by electronic application, accessible from each reserve’s homepage. Portions of Jepson Prairie and Stebbins Cold Canyon Reserves are open to the public without prior reservation; see the respective reserve homepages for details. The other reserves are closed to the public except for special events and activities..
