Episode Synopsis

Bark beetles evolved to live in western forests. But in recent decades the number of beetles has grown so large that they are killing millions of acres of forests. Here, we talk to Dr. Richard Hofstetter about these now infamous beetles. We learn about what these beetles do for forests, what happens when their numbers swell out of control, and the acoustic research that might help keep them in check.
