Abstract

Dwarf mistletoes in the Pacific Northwest infect true firs, larch, pine, Douglas-fir, and hemlock. Forty-one percent of all stands east of the crest of the Cascade Range and 10 percent of west-side stands are infected. General characteristics of dwarf mistletoe are discussed including mortality and growth losses rate of spread within a tree and within stands. Relation of site class and growth loss and the effect of management activities.
