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…

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…

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…
