After the Fires: Protecting L.A.’s Trees While Learning Lessons for the Future

A wind-driven brush fire in Simi Valley could push east sending flames and smoke plumes into parts of Los Angeles, less than 18 months after catastrophic wildfires hit the communities of Altadena and Pacific Palisades. 

The lessons from those twin 2025 fires are still being learned as researchers from University of California, Davis, other institutions in the state and the country are working to understand the effect on air quality, human health and the environment. 

What Barn Owls Hear Over California Vineyards

After the sun sets and darkness falls over the vineyards near Lodi, American barn owls start to glide above the grapevines in search of rodents below. As the birds hunt, researchers at the University of California, Davis, and California State Polytechnic University, Humboldt, and San Luis Obispo, are paying attention to how noises echoing through the fields influence these nocturnal raptors.

The Fungus That Spoils Nearly Everything

Even if you haven’t heard of Botrytis cinerea, you’ve likely seen it — slowly growing in your store-bought blueberries, tomatoes or even on your beautiful orchids. Commonly known as gray mold, the fungus attacks hundreds of plants. For years, scientists have unsuccessfully tried to breed crops that could resist the fungus. New research from the University of California, Davis, suggests decades of crop breeding strategies may have overlooked a crucial piece of the puzzle: the pathogen itself.

Study Projects Plant Extinction Rates Through 2100

No matter how fast a species under threat can move, escape can only be successful if the new destination can meet its needs.

An ecological modeling study from the University of California, Davis, found that 7% to 16% of global plant species studied are expected to lose more than 90% of their range, facing high risk of extinction by 2100 under current climate change projections.

Grassland Bird Diversity in Sacramento County

Across an expanse of open grassland in Sacramento County, an eight-foot, stream cut bank holds dozens of mud-domed bird nests, where tiny heads peeked out before a colony of cliff swallows took flight. Cliff swallows are small migratory birds that arrive in the Central Valley each spring to breed, and while they now commonly nest on bridges and freeway overpasses, finding their nests built in a natural setting is a striking and special sight, particularly in California’s Central Valley.
