A root disease evaluation was completed for the
Ducharme logging unit near the southeast corner
of Flathead Lake. Extensive root disease was
found on Douglas-fir throughout the unit. The
major pathogen on the site was Armillaria
meilea. Black stain (Verticicladiella sp.) was
isolated from one tree which was also infected
with A. mellea. Bark beetles were not associated
with mortality in the unit. Several
management approaches to reduce disease losses
are discussed.
