Good news, bad news about forest beetle infestations
PUBLIC LANDS -- A pine beetle outbreak that has left many Western states with vast stands of dead and dying trees has eased for the second consecutive year, the U.S. Forest Service says.
That's the good news.
The bad news is that more trees are dying at higher elevations as beetles take advantage of warm winters to gain a new foothold.
And with trees on roughly 42 million acres killed by various beetles since 2000, it could take decades for some forests to fully recover.
