Scientists fear that the swarms of mountain pine beetles that have killed more than half of all lodge pole pines in British Columbia may eventually make their way into forests in the US. And while cold winters typically kill most of the beetle larvae, the region has recently witnessed unusually higher temperatures that have allowed the beetle to thrive for longer periods of time. The beetle has recently been found in Alberta, and scientists told BBC News that they could threaten jack pine...

By Linn Mills Here are issues that were brought up to me this past week at the Springs Preserve. Thinning pines: Pines are beautiful when they are properly thinned. This exposes their inner structure, allowing light through so you can grow ground covers and, more importantly, it cuts down on falling needles.

By LON WAGNER By Lon Wagner The Virginian-Pilot They look like something the environmental artist Christo might have done. Elegant in their sheer starkness. Tall and narrow and white, and dead. Hundreds of pine trees, their bark now gone, stand like nature's tombstones, demanding attention just before cars pass the toll booth on the north side of the Chesapeake Bay Bridge-Tunnel. What happened to the trees - are they diseased, or did pests kill them? - has become the top question...

Amy Gannon, hatchet in hand, sliced a slab of bark from a lodgepole pine tree near Wolf Creek, Mont., and quickly spotted a mountain pine beetle larva no bigger than her pinky fingernail. "This tree's done for," said Gannon, an entomologist with the Montana Department of Natural Resources and Conservation. As wildfires roar through tinder-dry forests in California, the mountain pine beetle is silently killing even more trees -- hundreds of thousands of acres of towering trees, mostly...

Most of Colorado's lodgepole pine trees stand to be dead within the next 5 years.  In 1996, a bark beetle infestation was detected, and last year it spread over 500,000 acres more than previous years. Federal forestry officials say that this brings the total count of affected acres to 1.5 million. This infestation mainly affects five northern counties which straddle the Continental Divide, and has recently spread to part of southern Wyoming and the Front Range. Those effected counties...
