While many ranchers are willing to help safeguard threatened plantspecies on rangeland, most have lacked identification guides that would help. To fill that void, UC Davis' Animal Agriculture Research Center has collaborated with California State University, Chico; the Plumas-Sierra County Cooperative Extension; and the U.S. Forest Service to produce "A Rancher's Guide to Plant Species of Concern." The pocket-sized photographic guide was written in lay terms and designed to endure the rigor of ranch work. It contains color pictures and descriptions of 12 potentially at-risk plant species found on Northern California grazing lands. "We hope the guide will help ranchers identify plants of concern and note the potential impact of grazing management on these plants," says Ian Garnett, director of the Animal Agriculture Research Center. "We encourage ranchers to document sightings of these sensitive plant species and share the information." Ranchers are in a unique position to help expand the understanding of animal impacts on specific plant communities and to influence future land-management decisions, he says.
