Abstract

The true firs are important species in Oregon and Washington forests, but root diseases, stem decays, and dwarf mistletoes cause more mortality, growth loss, and cull in these species than in any other. This paper consolidates research, observations, and management techniques for diseases of true firs, especially the effects of silvicultural activities on root diseases, stem decays, and dwarf mistletoes.

Keywords

Root disease, dwarf mistletoe, stem decay, thinning
