Abstract:: Dwarf mistletoes reduce tree height and diameter, and thereby cause a reduction in volume production. We estimate that volume reduction in Montana is about 33.2 MM cubic feet per year. Mistletoe effects are problems in some areas because of the demands we have placed on the Forests for goods and...

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)....
