Improving the Management of Rangeland Ecosystems

The Power of Data: Improving the Management of Rangeland Ecosystems (Video)

Plant Sciences professors Ken Tate and Valerie Eviner, UC Davis, are highlighted in this video about rangeland management and working landscapes. Ken Tate is a statewide Cooperative Extension Specialist in California, who studies working rangelands to aid ranchers and managers in implementing sustainable livestock grazing management. Valerie Eviner studies variations in ecological controls over plant communities and ecosystem processes, and uses this understanding to improve management of ecosystem services, plant invasions, and restoration, particularly under changing environmental conditions.

Determining the best grazing regimen, which is critical for ecology, and implementing optimum management practices are the focus of the video. Working with land managers, ranchers, and policymakers is part of their work, and is addressed in the video. The challenge of invasive species and their role in forage and species diversity, along with pest and drought impacts, are also covered.

Tate and Eviner worked with Western Sustainable Agriculture Research and Education (SARE) for funding to implement field research and onsite management practices. The online California Ecosystem Management Database that they developed highlights effective practices at specific sites in the Central Valley — data was collected from 3,000 sites.

The ultimate goal is to provide tools for land managers to connect management practices with desired outcomes at specific sites.
