The Douglas-fir beetle was found in Cordillera in the summer of 2017 and has already stricken several old-growth trees at the Trailhead. Cordillera Healthy Forest worked with the Forest Service and State epidemiologist to develop a Douglas Fir Beetle Action Plan for the community. Property owners in the target area, which includes Peregrine Drive, Red Tail Ridge, Fenno Drive, Red Draw, Forest Trail and Black Bear Trail, should contact Bill Wentworth, healthy forest project manager, at 970-569-6250 for an inspection or to report an infested tree.Indication of an infested tree include:•Small groups of dead and dying Douglas-Fir trees.•Needles fading from green to red-brown before dropping. •The presence of reddish-brown boring dust around the base of trees and within the cracks and crevices of the bark.•Streaming resin along the trunk.•Wood pecker damage.•Exit holes.
Douglas-fir beetles produce one new generation each year with some larvae and adult beetles overwintering in the bark of infested trees. They attack trees in April through June and sometimes into August.
