RM-GTR-250: User's guide to the Douglas-fir beetle impact model


Marsden, Michael A.; Eav, Bov B.; Thompson, Matthew K. 1993. User's guide to the Douglas-fir beetle impact model. Gen. Tech. Rep. RM-250. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 9 p.

Douglas-fir beetle (Dendroctonus pseudotsugae Hopk.) occurs throughout the range of its principal host, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). At epidemic levels, the beetle causes considerable mortality in large-diameter Douglas-fir trees. Wind storms, drought, fire, and other factors have been reported as precedent conditions for epidemics of Douglas-fir beetle. An impact model has been developed to simulate tree mortality during such epidemics. The model has been linked to the Stand Prognosis Model (Forest Vegetation Simulator). This is a guide for using the model.

Keywords: Dendroctonus pseudotsugae, Pseudotsuga menziesii, Douglas-fir beetle, simulation, stand modeling, tree mortality, prognosis
