For the most part the epidemic has been confined to lodgepole pine forests. Over the past four years, mountain pine beetle infestations have developed and expanded in high elevation lodgepole pine forests east of the Continental Divide. By 2007, populations of mountain pine beetle in lodgepole pine forests along the northern Front Range (Boulder, Clear Creek, Gilpin, and Larimer Counties) had reached epidemic levels and were moving into the lodgepole pine/ponderosa pine transition zone. Members of northern Front Range communities have expressed concerns regarding the potential impacts of this beetle epidemic on ponderosa, limber, and Rocky Mountain bristlecone pines.born digitalreportsengColoradomountain pine beetleHopkins Host Selection Principlepotential lossrestorationWill the Mountain pine beetle epidemic spread from lodgepole pine into ponderosa pine along the northern Front Range counties of Colorado?
