Major forest pest problems in the District in 1977 were mountain pine beetle along McNaughton Lake and the Stuart - Takla lakes area, conifer sawfly along the Fraser River east of Prince George, spruce beetle in the Carp and Inzana lakes area, tent caterpillar in the McBride - Valemount area, and larch sawfly west of Prince George.??A foliage blight on trembling aspen was evident between Germansen and Williston lakes; winter drying caused widespread damage in the Pine Pass and Monkman Pass area, and late frost killed numerous buds near Prince George.

Book Description
Bark beetles caused extensive mortality of lodgepole pine, Engelmann spruce, Douglas-fir and alpine fir throughout the Kamloops Forest District. Spruce budworm continued to cause severe defoliation in the Fraser Canyon - Carpenter Lake area but infestations declined near Adams and Shuswap lakes. A pine sawfly defoliated lodgepole pine near Vavenby and Clearwater River. A cooperative survey detected European pine shoot moth in pines at Kamloops and Kelowna. Foliar diseases were abundant on a variety of hosts and root rot infections were extensive in the Okanagan Valley.
