Wood Research United States Bibliography; Forests and forestry Research United States Bibliography; Forest fires Research United States; Insect pests Research United States; Forest management Bibliography. A Model to Estimate the Rate and Amount of Lodgepole Pine Losses to the Mountain Pine Beetle Unchecked epidemics of mountain pine beetles can kill most merchantable lodge- pole pine in a stand within 3 to 7 years. A model to simulate the rate and amount of these losses to the mountain pine beetle has been developed by the Inter- mountain Station. Simulating tree losses with the model helps the land manager focus attention on stands where high tree mortality is likely. These stands can be harvested or treated silvicul- turally before a beetle outbreak occurs so that tree losses are prevented or minimized. The model is based on ecological rela- tionships of mountain pine beetle and lodgepole pine as determined by compre- hensive research at the Intermountain Station on population dynamics of the beetle. The model was verified in 2,500 stands and now is used to simulate losses to the mountain pine beetle in all lodge- pole pine stands on Federal and State lands over a wide area.
