Book Description
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.
