Volunteers needed to stop SOD from killing oak trees.

In California, sudden oak death disease has killed more than 50 million of the state’s iconic oaks and tanoak trees between Humboldt County and Monterey County, threatening survival of several tree species. In 2019 alone, 1 million tanoaks succumbed to sudden oak death (SOD), according to 2019 tree mortality data released by the U.S. Forest Service.

Native Plants: How to re-oak your neighborhood.

California’s native oaks have always evoked the feeling of “home” for me, even though I spent my first quarter-century well east of the Sierra Nevada. From afar, I appreciate the muscular, sculptural beauty of coast live oaks. Up close, I love the multitude of birds and other critters that are drawn to the trees.

Valley oak tree could provide insight into how plants will adapt to climate change.

The valley oak, a tree species native to California, is at the root of a new means of determining an organism’s genetic fitness in the face of climate change.

A UCLA-led study found that under current global warming conditions, trees such as valley oaks are unable to thrive, adapt and proliferate as before. The study was published in the Proceedings of the National Academy of Sciences of the United States of America in November.

Plant an oak in 2020: Make a home for insects and animals.

Q: Over the holidays, I was reading about the insect apocalypse. I've decided to include planting an oak tree in my New Year’s resolution list. I read that oak trees provide the most habitat for insects.

‘Tis the Season for Oak Root Fungus to Strike.

Armillaria is a serious forest pathogen common throughout California, having evolved to live where native oaks have grown. It is a long-lived, parasitic fungus that survives off dead root material, eventually killing a susceptible host. It does not affect oaks unless they are already stressed by disease or overly-watered lawns underneath the canopy.

What Oak Trees Mean to the Health of Vineyards.

There’s something iconic about driving through California’s Central Coast and seeing giant oak trees scattered across the landscape. Throughout history, however, not all Californians have appreciated the majesty and value of these trees. During the first half of the 1900s, many oak trees were removed to make way for agriculture and urban development. This, together with poor regeneration, contributed to declining populations of some of California’s 20 native oak species, most notably the valley oak.

The evolution and impact of Santa Cruz Island's Scrub Jay.

While its overall population numbers are just around 2,000, the island scrub jay’s impact on the world around it is enormous. By caching thousands of acorns every year, it has helped to restore Santa Cruz Island’s precious oak woodlands.
