UC Davis Study Shows Slowed Growth of Douglas Fir Trees in Drought

Douglas Firs are particularly sensitive to the drought affecting California and much of the Western United States.

A new study from the University of California – Davis’ College of Agriculture & Environmental Sciences pinpointed exactly how the trees are being harmed. They analyzed core samples, gathered from up and down the West Coast, to understand how Douglas Firs growth rates have changed over the past century.

According to project lead Christina Restaino, “Throughout the life of these trees, Douglas firs have experienced a lot of different conditions … The conditions that have been the warmest and the driest have slowed their growth the most.”
