Genome Project Will Restore Health of Coast Redwood and Giant Sequoia Forests

Some trees are better at surviving drought, fire, pests, and diseases than other trees. By identifying the genes responsible for these adaptations, scientists can compile a scalable database that will aid resource managers as they plan long-term conservation strategies, particularly as the climate changes. Professor David Neale, UC Davis Department of Plant Sciences, showed in…

Earth’s Oldest Trees in Climate-Induced Race up the Tree Line — Bristlecone pine trees in the Great Basin are losing the game of leapfrog with the limber pine

Summary: Tree-line species are shifting in the Great Basin of the U.S. Limber pine trees are ‘leapfrogging,’ slowly, over ancient bristlecone pines upslope. If limber pine trees block bristlecones from advancing upslope, bristlecones could face local extirpations. *     *     *     *     * Bristlecone pine and limber pine trees in the Great Basin region are like…

Water Conservation: The New ‘Normal’ – Drought Irrigation Strategies

Since water conservation will be an ongoing practice in California, University of California scientists are continually developing practical information for agriculture, rangelands, urban landscapes, and animal production. This series of publications was produced by UC experts throughout California. Published by UC ANR, authors include professors and Cooperative Extension specialists in the Dept. of Plant Sciences…

Carbon Reduction, the Unrealistic Paris Agreement, and Alternatives for California

Climate scientists from three countries have determined that the carbon reduction goals set at the Paris Agreement in 2015 are not feasible. Regardless of whether the U.S. remains part of the Paris climate accord, scientists at the University of California, Davis, are developing additional agricultural methods to offset increases in atmospheric greenhouse gases, thereby reducing…

How Much Drought Can a Forest Take? Aerial Tree Mortality Surveys Show Patterns of Tree Death During Extreme Drought

Quick Summary Trees in the driest, densest forests are most vulnerable to dying in extreme drought Effects of extreme drought on forests can take years to surface High tree mortality rates likely to continue as drought effects linger Why do some trees die in a drought and others don’t? And how can we predict where…

Restoring Back to the Future

Climate change raises an important question for restoration ecology: What’s the best way to heal the land when its future environment won’t look like its past? “It’s a huge issue,” said Valerie Eviner, a restoration ecology professor in the Department of Plant Sciences. “We look at our changing climate and ask, ‘What will grow? What’s…
