COLORADO — Forest experts are warning that Boulder’s foothills could look markedly different this year as a mountain pine beetle outbreak intensifies, with potentially far-reaching impacts on recreation and fire risk. Landowners are urged to watch for signs of beetle infestation. The state has taken action: Gov. Jared Polis announced a task force in December aimed at protecting Front Range forests from mountain pine beetle over the next decade. Boulder County has seen increased beetle activity in several areas, including upper Lefthand Canyon and Jamestown. Years of drought, warmer temperatures and overcrowded forests have weakened trees, creating ideal conditions for beetles to spread rapidly and overwhelm remaining healthy stands. …The brood of beetles already in trees and poised to spread this summer is substantial, according to Colorado State Forest Service entomologist Dan West. “It’s kind of this cake that’s already being baked,” West told Boulder Reporting Lab.
