Abstract:: Residual Douglas-fir, western larch, and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning, will reduce mistletoe intensity and increase future volume yields. Present net worth of the project is $48.05/acre. Benefit cost ratio is 1.97/1. Use of pest...
