Abstract

Pest problems in the Region were: mountain pine beetle around McNaughton Lake and in the Fort St. James area; spruce beetle near Carp, Hodda, Stuart, Trembleur and Nation lakes; larch sawfly west of Prince George; tent caterpillar near McBride. Two-year-cycle spruce budworm populations increased along the Holmes and Bowron rivers and an outbreak of black army cutworm occurred north of Fort St. James.

A leaf and shoot blight affected trembling aspen over a wide area in the western part of the Region. Rust and blight diseases affected alpine fir foliage from MacLeod Lake to Mackenzie.
