Although manyinsects and diseases are native to the state, underlying forest conditionscombined with climatic factors can cause them to operate at an intensity orscale that causes concern. Noxious weeds, such as tamarisk, cheat grassor meadow knapweed, however, are not native to Colorado’s forests andtheir presence serves to displace native species, alter hydrologic regimes,increase wildfi re risk and cause other damage within the ecosystem. Althoughthe extent of future climate change impacts is unknown, current trendsindicate the possibility for increased susceptibility to fi re, insects and disease,decreased forest cover at lower elevations and loss of habitat for some forestdependentspecies.Insect and Disease Overview: A number of insects and diseases regularlyimpact the condition of Colorado’s forests. Some are exotic, or introduced,but most are native and always present at endemic levels.Natural cycles of insect and disease activity are an important component ofa functioning forest ecosystem because they contribute to the diversity ofsizes, age classes and species types across the forest landscape. Forestinsects also provide food for wildlife and their activities can result in nesting,roosting and hunting sites for birds and other animals. They also can createoccasional small openings that increase growth of understory grasses andforbs. Insects of primary concern in Colorado include the mountain pinebeetle, spruce beetle, piñon ips beetle, western spruce budworm and balsambark beetle. Diseases of concern include dwarf mistletoe and armillaria root31
