Public Lands Grazing
Nearly half of the grazing land in California is held in the public trust. We work with a variety of natural resource agencies to study and promote both environmental sustainability and agricultural production on the diverse ecosystems that comprise California's public rangelands.
Riparian Conditions on National Forest Grazing Allotments
Mountain meadows and riparian areas across the western United States constitute a unique and critical natural resource. On California's national forest lands, mountain meadows and their broader forested landscape provide a multitude of ecosystem services, including flood water attenuation, diverse and productive forage for cattle and wildlife, and outdoor recreation for over 26 million people.
Cattle Grazing, Mountain Meadows, and Yosemite Toad
World-wide population declines have heightened concern for amphibian conservation on working landscapes. Across the Sierra Nevada's national forest lands, where almost half of native amphibian species are considered at risk, permitted livestock grazing is a notably controversial agricultural activity.
Water Quality on National Forest Grazing Allotments
Grazing allotments on U.S. Forest Service (USFS) lands provide summer forage for cattle, surface water for public recreations and consumption, and critical aquatic habitat. There is substantial concern that public lands cattle grazing degrades water quality, threatening human and ecological health.
Cattle Grazing Management and Aspen Restoration
Aspen restoration in grazed landscapes is a priority for many resource managers. Stand protection practices such as exclusionary fencing are often recommended where browsing is suppressing aspen regeneration. However, wide-spread exclusionary fencing of stands may not be ecologically or economically practical.
Montane Meadow Plant Community Response to Livestock Grazing
Livestock grazing on public lands is a controversial issue across the western United States, and policy-makers and managers are progressively charged with balancing diverse societal goals on these national lands. Montane meadows represent less than 10 % of the Sierra Nevada, but are critical to both summer cattle grazing and a variety of eco-system functions.
