In the Sierra Nevada, it’s estimated that tens of millions of trees have died as a result of drought, many of which succumbed to infestations from bark beetles. As a result, we’ve been told our risk of wildfire is far higher than normal, but FM89’s Kerry Klein says the science doesn’t necessarily agree. Gaze across a hillside at 5,000 feet in the Sierra Nevada, and that landscape, usually a wash of green pines, firs and cedars, is probably smudged with reds and browns.
