About the Western Spruce Budworm Infestation

White fir and Douglas-fir trees in North Cheyenne Cañon, west of Colorado Springs are currently experiencing chronic defoliation and bud damage from the Western Spruce Budworm. Canopy loss caused by these pests can be severe following repeated infestations and highly visible.  Thousands of grey, completely dead trees can be seen by park users. The control of the infestation is critical to protecting the live green canopy of the trees, reducing defoliation and death of the forest, protecting water quality and protecting the area from long term fire hazards.
