Drought, Climate Change Slow Growth of Douglas Fir Forests

A new study finds the West is likely to see slower-growing Douglas fir trees in the future, as temperatures and droughts increase with climate change. Researchers with the University of California-Davis took core samples from 122 Douglas fir trees across the region to measure how fast the trees grew over a 91-year period. Climate models show stressful growing conditions will be be more frequent in the future, and they’ll last longer as global temperatures rise.
