Tree-ring data from black spruce indicate increased growth in response to increased temperatures.
Editor’s Summary
A future for boreal forests
Conservation under climate change presents the challenge of predicting where will be suitable for particular organisms and ecological communities in the future. D’Orangeville et al. assess the probable future range for boreal forests in eastern North America, which are expected to be subject to large temperature increases in their natural range. Using tree-ring data from many thousands of forest stands, they delineate the geographical extent of the region where tree growth responds favorably to higher temperatures and where the forest should persist at least until 2070.
