Long before Governor Brown declared an official drought for the state, many of California's ranchers knew this would be a tough year. Drought can increase the risks of animal poisonings and nutritional imbalances, and necessitate additional vigilance to assure cattle health and productivity. Veterinary toxicologists Robert H. Poppenga and Birgit Puschner, with the California Animal Health and Food Safety Laboratory System at UC Davis School of Veterinary Medicine, provide this critical information to dairy and beef producers to keep their livestock healthy during the drought. Key threats to cattle include:
Water quality — Water is the most critical factor in the...

How do people really feel about cattle grazing on public lands? According to a study of comments on social media, park users don't feel as strongly as one might surmise from attending a public hearing about cattle grazing in parks.
To get a more complete picture of public perceptions of cattle grazing, Sheila Barry, University of California Cooperative Extension advisor in the San Francisco Bay Area, analyzed photos and comments in the photo-sharing website Flickr.
Her study, published in the February 2014 issue of Environmental Management, showed that Flickr can...

Cattle grazing and clean water can coexist on national forest lands, according to research by the University of California, Davis.
The study, published June 27 in the journal PLOS ONE, is the most comprehensive examination of water quality on National Forest public grazing lands to date.
“There’s been a lot of concern about public lands and water quality, especially with cattle grazing,” said lead author Leslie Roche, a postdoctoral scholar in the UC Davis Department of...

The Sierra Nevada and Coastal Range foothills are replete with wide open spaces - a home for birds and other wildlife, majestic oaks and grazing cattle. The bucolic countryside vistas that come courtesy of California’s ranchers are among the many public benefits of rangeland grazing.
“The public doesn’t always realize what ranchers are doing and how that benefits everyone,” said Bill Tietje, UC Cooperative Extension natural resources specialist based in San Luis Obispo County. “No one really thinks about it, until it’s gone.”
Many rangeland benefits can be grouped as “ecosystem services.” According to scientists:
- Rangeland plays a role in the state’s water cycling. Eighty percent of California water flows...
