The University of California’s newly launched California Naturalist program is a way for the institution to spread research-based knowledge about environmental stewardship and nature preservation. Rather than simply educating students, the program engages citizens of all ages through discovery and action in the science of conservation.
After completing the program, California Naturalists will become a committed corps of citizen scientists trained and ready for involvement in natural resources education and restoration.
“To ensure the sustainability of natural resources in California, we need citizens who participate in natural resource conservation, understand the...
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...

In the early 1800s, European immigrants introduced the fast-growing giant reed arundo (Arundo donax) into California to use the canes for musical instruments. The plants were also used for erosion control and the reeds used for thatched roofing. However, it has since naturalized and become a serious pest in the state's natural waterways.
Arundo can grow at a rate of four inches per day and can reach heights of 30 feet. It reproduces and spreads when sections of the stem or root break off and float downstream.
Dense stands of arundo displace native riparian species. The plant requires a significant amount of water, reducing fish, wildlife and people. In addition, clumps of arundo and the soil around their roots...
The University of California will break ground on the new 5,000-square-foot building this fall. In addition to providing meeting facilities for 200 and display space for a collection of natural and Native American museum pieces, the building itself will be a model of integrated green design, according to center director
If the return of earthworms to farm fields is an indication of success, then Sano Farms is on the right track.
“I haven’t seen earthworms in these fields in years,” said Firebaugh farmer Alan Sano. Sano and his partner, Jesse Sanchez, combine subsurface drip irrigation, winter cover crops and strip tillage to consistently produce a high-yielding crop of processing tomatoes.
In addition to boosting yield, the system they developed for the 4,000-acre farm is cheaper, increases soil organic matter and improves the tilth of their silty clay soil.
The farmers took several trips to the Midwest and consulted with UC Davis Cooperative Extension specialist
