Pine Beetle Information

Pine beetles are a natural part of the Arapaho and Roosevelt National Forests' ecosystem. However, due to drought conditions and a stressed forest, the current outbreak of Mountain Pine Beetles has reached epidemic levels. Survey results reveal that the bark beetle infestation affected about half a million new acres in 2007 in Colorado, bringing the total number of acres of infestation up to 1.5 million since the first signs of outbreak in 1996.

Many activities are taking place on the Arapaho and Roosevelt National Forests to address the current situation. Information on these are listed below, as well as additional resources for information on the Mountain Pine Beetle. Please note that some recreational activities may be affected, including delayed openings of campgrounds, campground and trail closures, and safety concerns. When recreating in the Forest please use caution around hazardous trees.
