Several species of bark beetles are presently killing lodgepole pine, ponderosa pine, limber pine, Engelmann spruce, subalpine fir and Colorado blue spruce. Beetle management options include forest thinning before an infestation takes hold, logging afterward, or leaving tree skeletons undisturbed. Perhaps even more concerning is that beetles are beginning to target novel species, such as the jack pine — found across wide swaths of Canada — that had escaped assault until now. Recorded Trail Ridge Road status: (970) 586-1222. The needles on conifer trees, like pines, begin to turn a reddish-brown color. In undisturbed forests, bark beetles serve the purpose of hastening the recycling and decomposition of dead and dying wood and renewing the forest.
