Climate change may speed up forests' life cycles
Date:9/11/2013

DURHAM, N.C. -- Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response.

Nearly 80 percent of the species aren't yet shifting their geographic distributions to higher latitudes. Instead, they're staying in place -- but speeding up their life cycles.

The Duke University-led study, published online Wednesday in the peer-reviewed journal Global Change Biology, is the first to show that a changing climate may have dual impacts on forests. It adds to a growing body of evidence, including a 2011 study by the same Duke team, that climate-driven migration is occurring much more slowly than predicted, and most plant species may not be able to migrate fast enough to stay one step ahead of rising temperatures.

"Our analysis reveals no consistent, large-scale northward migration is taking place. Instead, most trees are responding through faster turnover -- meaning they are staying in place but speeding up their life cycles in response to longer growing seasons and higher temperatures," said James S. Clark, H.L. Blomquist Professor of Environment at Duke's Nicholas School of the Environment.

Anticipating the impacts of this unexpected change on U.S. forests is an important issue for forest managers and for the nation as a whole, Clark said. It will have far-reaching consequences for biodiversity and carbon storage.

To test whether trees are migrating northward, having faster turnover, or both, the scientists went through decades of data on 65 dominant tree species in the 31 eastern states, compiled by the USDA Forest Service's Forest Inventory and Analysis program. They used computer models to analyze the temperature and precipitation requirements of the trees at different life stages, and also considered factors like reproductive
