Pine beetle infesting new B.C. tree species

The mountain pine beetle is on the move to higher elevations and threatening new species of trees and entire sensitive forest ecosystems, according to a new study.

The resilient beetle has wreaked havoc mainly on lodge pole pine in B.C., ruining 18 million hectares of forest — the equivalent of about five Vancouver Islands.

Researchers at the University of Wisconsin-Madison say the bug is now attacking whitebark pine forests in the northern Rockies in the western U.S. and B.C.
