Decades of research-based knowledge about the history, physical characteristics and vegetation in California annual grassland, oak-woodland and chaparral ecosystems has been consolidated in a new nine-part PDF document. The 200-page publication, The Ecology and Management of Annual Rangeland Series, is available for free download from the UC Agriculture and Natural Resources catalog.
The series includes past and current practices for managing vegetation, grazing and livestock compiled by researchers at the University of California, U.S. Department of Agriculture and other agencies...
When California was part of the Wild West, it took a certain amount of guesswork to move cattle from their home range to summer pastures while making sure sufficient forage was left behind to hold the cattle over till fall rainfall spurred new growth.
“Ranchers eyeballed it,” said Theresa Becchetti, UC Cooperative Extension livestock and natural resources advisor. “In time, second-, third-, and fourth-generation ranchers got pretty good at deciding, but UC Cooperative Extension introduced a more scientific approach.”
In the spring of 1936, the USDA Forest Services began measuring ungrazed forage at the San Joaquin Experimental Range in Madera County....

Rose Hayden-Smith, UC Cooperative Extension digital communications in food systems & extension educator, talked with Matthew Shapero about his work protecting California's natural resources. This is the second in a series featuring a few scientists whose work exemplifies UC ANR's public value for California.
Scientific evidence of a warming climate in California and across the globe is clear, but the impacts on ecosystems and agriculture are still difficult to predict.
Sophisticated computer models are used to forecast future climate. Understanding that temperature and precipitation levels will change in the future does not tell the full story: UC Agriculture and Natural Resources researchers also want real-world experience under those future conditions.
Moreover, some agricultural operations have higher sensitivity to the changes than others. Rangeland forage is particularly sensitive to climate changes since, unlike irrigated agriculture, ranchers rely solely on precipitation. They have no...
California is searching for solutions to the wildfire crisis. Livestock ranchers believe they can help.
At the 14th Annual Rangeland Summit in Stockton in January, more than 150 ranchers, public land managers and representatives of non-profit organizations that work on land conservation gathered to share research and experiences that outline the value of cattle and sheep grazing on rangeland.
Since California was settled by Europeans, cattle and sheep have been an integral part of the state's history.
“Cattle can control brush,” said Lynn Huntsinger, UC Cooperative Extension specialist at UC Berkeley in a presentation on brush management. She...
