Book excerpt: Excerpt from Bark Beetle Risk in Mature Ponderosa Pine Forests in Western Montana Objectives of the study were to be achieved by annually measuring the mortality of ponderosa pine trees caused by the pine beetle over a 10-year period following the single initial risk rating of the trees. For this purpose, 35 plots having a combined net timbered area of 553 acres were established between 1948 and 1958 in widely scattered stands of virgin mature ponderosa pine in Montana west of the Continental Divide.
