The Mountain Pine Beetle (a.k.a. bark beetle) is at epidemic levels throughout the western United States, including here in the Rocky Mountain Region. Forest here affected, include forests in Colorado, Wyoming and South Dakota. In northern Colorado and southeastern Wyoming, mountain pine beetles have impacted more than 4 million acres since the first signs of outbreak in 1996. The majority of outbreaks have occurred in three forests: Arapaho & Roosevelt,  White River, and the Medicine Bow/Routt NF.

Concern about the epidemic is particularly high in these areas due to watershed values and recreation use. Mitigation is critical because hazardous fuels and falling trees impact watershed resources, human health and safety, and basic services such as travel, electricity, and water.


The following forests in the Rocky Mountain Region are currently responding to the bark beetle epidemic. To find more information on how bark beetles have impacted forests in the Rocky Mountain Region, click on the following links:
