Valentine Eastern Sierra Reserve (VESR) is a field research station, two of 39 sites in the University of California’s Natural Reserve System (NRS). The Reserve is administered by UC Santa Barbara and consists of two sites, Valentine Camp and the Sierra Nevada Aquatic Research Laboratory (SNARL), located 15 miles apart near Mammoth Lakes in the eastern Sierra Nevada. The mission of 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. VESR provides protected wildlands, on-site experimental facilities, as well as the support facilities for conducting studies of natural systems over a large part of central, eastern California and western Nevada. The Reserve is open, by application, to any bona fide researcher or instructor. We welcome your interest and your inquiries..
