Blue Oak Ranch Reserve Facts
Founded in 2007, Blue Oak Ranch Reserve is a 3,280 acre Biological Field Station and Ecological Reserve, one of the 39 units of the UC Natural Reserve System, and is operated jointly by the Office of the Vice Chancellor for Research, Berkeley Natural History Museums and the NRS. The Reserve provides a wealth of research and teaching opportunities in a wide range of important Californian habitats.
The shared mission of the 39 Reserves in the Natural Reserve System is to contribute to the understanding and wise stewardship of the Earth and its natural systems by supporting university-level teaching, research, and public service at protected natural areas throughout California.

With funding from the California Wildlife Conservation Board, new facilities have been completed this year to accommodate the needs of up to 50 students and faculty in conditioned and seasonal cabins, large meeting room, 20 seat classroom, field lab, office space, group kitchen and restrooms. These facilities are nearly energy self-sufficient with an off the grid solar photovoltaic power system, solar hot water heaters, wood stoves, and well water. Our roads have been improved to provide year-round access to users for their field courses, research projects, and public outreach activities.
