Dense stands of Douglas fir trees in the Klamath Mountains

Caption

Dense stands of Douglas fir trees surround South Twin Lake in California. Decades of logging and fire suppression have shifted the composition of forests in the region, favoring fire-sensitive softwoods, like fir, over fire-resistant hardwoods, like oak.
