Stebbins Cold Canyon Reserve, set in a steep, north-facing canyon of the northern Coast Range, provides excellent opportunities to study plant and animal communities of both the inner and outer Coast Ranges. Differences in slope, exposure, and moisture regimes promote a variety of undisturbed habitats, including valley and foothill grasslands, blue oak woodland, chamise chaparral, lower montane chaparral, mixed riparian woodland, and intermittent foothill stream.
Year-round springs provide watering areas for many wildlife species, such as bear, mountain lion, blacktailed deer, ringtail, and turkey. A total of 108 bird species (35 nesting), eight amphibian, eighteen reptile, 43 mammal, and more than 290 plant species have been identified at the reserve.
Adjacent protected lands held by the U.S. Bureau of Land Management and the California Department of Fish and Wildlife greatly expand the effective research area.
The reserve is named in honor of G. Ledyard Stebbins, a world-renowned plant geneticist and longtime professor at UC Davis and Berkeley. Stebbins was an avid naturalist with a strong interest in conserving natural biotic communities.
The site is fully open to the public. Approximately 65,000 people visit the reserve’s nine miles of hiking trails annually to explore its canyon bottoms and ridgetops.
The reserve is available for field trips by elementary and secondary schools, and collaborates on a number of local school interpretation and curriculum development projects. The Stebbins Docent Program aims to educate the public as an impact mitigation tool, and a means to increasing Citizen Science opportunities in the reserve. The reserve also provides opportunities for the establishment of long term programs monitoring environmental change.
The site is visited by university courses in wildlife field techniques, California floristics, range science, wildlife biology, botany, plant and fire ecology, and geology field studies. The reserve also hosts UC’s Wild Davis and ecological restoration capstone projects, which contribute to initiatives relating to reserve management and decision-making.
