Abstract

Assessment of the potential danger posed by the mountain pine beetle in lodgepole pine stands was performed in the Crane Mountain area near Big Fork, Montana. More specifically, an area of 54000 square meters of timber was studied, paying close attention to the amount of entries into lodgepole pine trees by the mountain pine beetle. Taking into account the number of lodgepole trees present, the maturity of the trees, and the degree of beetle infestation, a decision could be made as to how this particular area should be managed. Alternatives for controlling further spread basically included clear-cutting, thinning, or allowing the beetle to proliferate unhindered.
