Water sloshes from a fill hole atop the plastic tank and strikes the dirt road in puffs of dust. With weathered hands, short nails and a once green felt cowboy hat, Adam Cline motors the water truck through the anxious herd. Piled on the floor beside him are several 40 pound bags of soybean meal, a more affordable protein supplement that protects the herd from malnourishment. Cline is fortunate: his cautious management strategies over the last two years will likely carry this operation through yet another drought year, without having to sell off any cows.
“Every rancher is equipped for an average drought,” he tells me. “But a drought like this is really hard to manage for… Emotionally it's like a battle...

Beautiful but unwelcome in California wildlands, brooms are shrubs introduced into North America from Europe in the mid-1800s. Common species include Scotch broom (Cytisus scoparius) and Portuguese broom (Cytisus striatus). Brooms were introduced as ornamentals, but also were used extensively for erosion control along roadsides and in mined areas.
Now growing profusely in California forests, on roadsides, and wildlands, brooms:
- Crowd out out desirable vegetation
- Form impenetrable thickets that limit access to some areas
- Shade out tree seedlings, and...

On Aug. 10, 2013, a wildfire started in a steep canyon on the Tahoe National Forest. When it was finally declared controlled on Oct. 8, the 'American Fire' as it was named, had burned approximately 27,440 acres, including half (1,100 acres) of the Sierra Nevada Adaptive Management Project (SNAMP) Last Chance study site.
Initiated more than 7 years ago, SNAMP is a collaboration project involving the University of California, UC Cooperative Extension, the US Forest Service, other state and federal agencies and the public that explores the effects of fuels reduction or thinning...

What if the trees in an orchard could be considered a savings account for energy and carbon? When determining the value of an orchard, we may account for the fruits it bears, the air it cleans, and the labor it employs. But with California climate policies in place and carbon becoming a tradable commodity, we may also be able to calculate and account for the long-term value of a tree itself.
A new study underway at the UC Sustainable Agriculture and Research and Education Program (SAREP) aims to help growers and policymakers better understand the energy use, greenhouse gas emissions, and carbon sequestration potential of orchard systems throughout California.
As trees grow,...

Air pollution is harmful to the health of people and animals. That much we know, but how does air pollution affect plants?
Scientists from 25 countries will gather on the Monterey Peninsula to discuss “Plants and the Changing Environment” in June. The 9th Air Pollution and Global Change Symposium will be held June 8-12 at the Asilomar Conference Center in Pacific Grove.
The goal of the series is to consider interactions of air pollution and global change and their impacts on vegetation.
“The symposium is unique in dealing with effects at all levels from molecular and cellular mechanisms, whole plant and crop impacts, all the way up to models of ecosystem and regional...
