Abstract
According to "Aerially Applied Verbenone-Releasing Laminated Flakes Protect
Pinus contorta Stands from Attack by
Dendroctonus ponderosae (mountain pine beetle) in California and Idaho," a US Forest Service–funded study appearing in the February issue of Forest Ecology and Management, not only has the "current epic mountain pine beetle outbreak in British Columbia, Canada, affected more than 9.2 million hectares and breached the Continental Divide," but it is "expected to continue until either the host is depleted or severe cold weather reduces beetle populations."
