Spruce beetles and climate change

The spruce beetle has changed the forests of southcentral Alaska, and it’s not done. On the next Outdoor Explorer, we’ll examine the forest changes driven by a warming climate. The most important factor has been these beetles. We’ll learn about their life cycle, impact, how to fight them, and what their explosion means for the places we recreate. We’ll also go deeper, learning what the best science predicts is next.

Thanks for listening!
