Spotting ants in the home or yard is no reason to reach for insecticide sprays or call an exterminator. UC Cooperative Extension experts say the insects can be managed by residents in ways that are effective, inexpensive, safe and environmentally kind.
“Ants are probably the No. 1 most common pests of our homes and gardens,” said Carolyn Kinnon, an environmental horticulturist and instructional associate at Mira Costa Community College. “Scientists find chemicals in our waterways that include pesticides commonly used to kill ants.”
Kinnon teamed up with UCCE community education specialist Scott Parker to present a

"Trees are poems that the earth writes upon the sky,” wrote Kahlil Gibran. But trees falling into power lines have sparked catastrophic fires and falling trees have injured nature lovers.
To prevent power outages, PG&E looks for trees near power lines that need to be trimmed or removed. To prevent power outages and other mishaps caused by failing trees, Matteo Garbelotto, UC Cooperative Extension forest pathology specialist at UC Berkeley, has incorporated science into a mobile application that can be used to determine whether a tree presents a hazard and should be removed.
“PG&E was doing tree surveys with pencil and paper,” said Garbelotto,...
This is one of a series of stories featuring a sampling of UC ANR academics whose work exemplifies the public value UC ANR brings to California.
Livestock and natural resources advisor Dan Macon came to UC Cooperative Extension three years ago with much more than a formal education in integrated resource management and agricultural and managerial economics.
He had years of hands-on experience running a successful foothill sheep operation, toiling long days and often into the night tending animals, irrigating pastures, training livestock guardian dogs and managing forage.
“I came to this position mid-career,” said Macon, who also accumulated...

Oak trees are iconic in California's landscape. Just about anything you would like to know about caring for the state's 8 million acres of oak woodlands is now accessible to the public online. University of California Cooperative Extension scientists have updated the UC Oaks website at https://oaks.cnr.berkeley.edu with oak ecology, management and oak woodland conservation information based on over 30 years of research.
“On the home page, we have highlighted oak topics – such as oak planting, oak ecology and rangeland management – that have been of special interest to website users,” said Bill Tietje, UC...
Healthy California wildlands were managed with periodic wild and cultural fires for millennia. As the state's population and development grew, officials suppressed most fires out of concern for people, homes and businesses.
Though well-meaning, the strategy left land overgrown with vegetation capable of fueling even more dangerous high-intensity wildfires. The past few years have seen an exponential increase in catastrophic wildfires in California.
As a result, there is growing interest in using prescribed fire to bring nature back into balance. Despite the current interest, communities have limited capacity, shared knowledge and experience to bring it back. To close...
