Creator:: Dooling, Oscar J., Johnson, Ralph R., Eder, Robert G., and United States. Forest Service. Northern Region
Abstract:: A permanent study was established in 1970 and 1971 to measure the impact, spread, and intensification of dwarf mistletoe on precommercially thinned Douglas-fir and lodgepole pine in Montana. Mean diameter growth on all plots was reduced 21 percent in Douglas-fir, but the reduction is only significant at the 0.15 level....

Abstract:: Potential problem pests found were Armillaria root disease, pocket gopher, western pine shoot borer, and white pine blister rust. Early detection of problem pests allows management actions to be taken if needed to prevent serious impacts. Unit managers should check the areas periodically and call on pest management specialists to...

Abstract:: Residual Douglas-fir are dwarf mistletoe-infested and pose a threat to regeneration. Felling of these residuals will reduce dwarf mistletoe intensity and increase future volume yields. The benefit/cost ratio at 4 percent for the current rotation is 0.51/1 on the Sula RD and 0.45/1 on the Darby RD (both negative ratios)....

Creator:: Gibson, Kenneth E., Dooling, Oscar J., and United States. Forest Service. Northern Region
Abstract:: Insects and diseases have the potential of seriously affecting timber associated resources on eastside forests within the foreseeable future. Within the past decade, lodgepole pine mortality attributed to the mountain pine beetle has totaled tens of millions of trees on the Gallatin and Beaverhead National Forests (NF) alone. In that...
