The Genetics of Drought Tolerance in Bioenergy Poplar Trees

August 22, 2019
Bioenergy crops are central to climate mitigation strategies. Bioenergy is a developing renewable resource, but it can impact land for food, and ecosystem services. Gail Taylor, Plant Sciences, received $2.52 million from the Department of Energy to develop bioenergy poplar trees for low-quality, marginal land.

Tahoe State of the Lake: Heritage Aspens and the Threat of White Satin Moth

August 02, 2019
While much of the 2019 Tahoe State of the Lake Report is about the lake itself, it also addresses the severe defoliation that many aspen stands are facing due to white satin moth. Information on other UC Davis tree loss and restoration research in the Sierra Nevada and other forests is cited.

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

July 09, 2019
An article in California Agriculture addresses how critical research is underway to understand the consequences of the massive wave of tree mortality in the Sierra Nevada. Urgent dialogue has started among UC scientists, forest managers, and public agencies to manage the consequences of the unprecedented tree die-off and increase the resiliency of forests to future droughts.

Thinning Forests, Prescribed Fire Before Drought Reduced Tree Loss

June 05, 2019
Thinning forests and conducting prescribed burns may help preserve trees in future droughts and bark beetle epidemics expected under climate change. Thinning and prescribed fires reduced the number of trees that died during the bark beetle epidemic and drought that killed more than 129 million trees across the Sierra Nevada between 2012–2016.

Nature Love Stories, in Homage to Valentine’s Day

February 12, 2019
All week, leading to Valentine’s Day, read a “first love” nature story, by campus scientists. This story was written by Professor Andrew Latimer, Department of Plant Sciences, who studies how plants respond to change, including fire, drought and climate change.
