California Plants and Climate Change — Even Worse Than we Thought?

Thursday, August 7th, 2008

KQED radio has produced an interesting follow-up to the recent Plos One paper predicting that climate change will have a dire impact on redwoods and other plants that are endemic to California, America’s biodiversity hotspot — plants found nowhere else in the world. (My blog on the paper is here.) A KQED reporter interviews the authors and finds they’re even more pessimistic than they were when they wrote the paper. One sobering prediction: Most of California’s endemic plants will die if global warming continues at its present pace. At the end of the century, redwoods could still be growing in California because adult trees are so long-lived. But since no seedlings will be able to survive, these adults will be the last redwoods on earth, a forest of the “living dead.”

On the KQED website you’ll also find an interesting slide show based on the radio interview.

Climate Roulette

How will America’s biodiversity hotspot — the state of California — fare as the climate changes? Not great, according to a new paper in the peer-reviewed online journal PLoS One. Its findings have implications for plant conservation that are guaranteed to raise a few eyebrows. 

The paper was the buzz among botanists at the annual conference of the American Public Garden Association in Pasadena a couple of weeks ago. California’s diverse and distinctive flora faces a potential “collapse,” David Ackerly, an ecologist at UC Berkeley and the senior author of the paper, told the LA Times. “As the climate changes, many of these plants will have no place to go.”
