Description: A science perspective of forest health in the Blue Mountains is summarized by using both historical and biological information. Many of the current pest problems are related to human activities that have occurred over the last 90 years. The almost complete loss of periodic low-intensity fires since 1900 plus extensive logging of pine have resulted in many thousands of acres of fir occupying pine sites. These fir forests are highly susceptible to pests and to catastrophic forest fires. Some long-term management strategies are now needed to alleviate the problems. Research recommendations also are suggested as part of the long-term solution.
Keywords: Keywords: Insects, forest diseases, fire, grand fir, Douglas-fir, ponderosa pine, silviculture, landscape ecology
