Many understory trees on proposed control areas are lightly to moderately infested with dwarf mistletoe. Control by thinning/ sanitation after logging will reduce infestations to a tolerable level and significantly increase volume yields in the future. The cost-benefit ratio of control is favorable.
Many nonmerchantable trees on proposed control areas in the Flathead Reservation are moderately to heavily infested with dwarf mistletoe. Control by sanitation-thinning is desirable and is both biologically and economically sound.

Dwarf mistletoe is a serious problem on the Flathead Indian Reservation. Since the early 197o's, a procedure called thinning-sanitation has been applied to lightly infested stands. Evaluation of this procedure indicated that average dwarf mistletoe infection levels now range from 7 to 50 percent in larch and Douglas-fir treated 10...
Dwarf mistletoes still pose management problems on the Flathead Reservation. We describe a management program, to be conducted in conjunction with the silvicultural program, which will help reduce the impact of dwarf mistletoe on Douglas-fir, western larch, and lodgepole pine. This program covers fiscal years 1986 through 1990.
