The California Tree Mortality Data Collection Network — Enhanced communication and collaboration among scientists and stakeholders

An article in the new issue of California Agriculture addresses how critical research and dialogue are underway to understand the consequences of the massive wave of tree mortality in the Sierra Nevada. Over 147 million dead trees were detected in California by the U.S. Forest Service from 2010 to 2018. The massive tree mortality, mostly…

Thinning Forests, Prescribed Fire Before Drought Reduced Tree Loss

Treatments May Reduce Loss in Future Droughts and Bark Beetle Epidemics Thinning forests and conducting prescribed burns may help preserve trees in future droughts and bark beetle epidemics expected under climate change, suggests a study from the University of California, Davis. The study, published in the journal Ecological Applications, found that thinning and prescribed fire…

New Insight Into Why Pierce’s Disease is So Deadly to Grapevines: Research could help diagnose disease early and increase plant health

Scientists are gaining a better understanding of Pierce’s disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa. While the bacterium has been present in the state for more than 100 years, Pierce’s disease became a more serious threat to agriculture with…
