Management of Douglas-fir Bark Beetles Southeast of Kamloops, BC

An experienced forest worker was concerned that Tolko had not removed all the trees it felled to trap Douglas-fir bark beetle before the insects emerged and that some of its harvest practices increased the infestation level in ungulate winter range in the Upper Salmon River area.

Douglas-fir bark beetle is normally present at low levels in ecosystems containing mature Douglas-fir but can increase to epidemic levels given the right conditions. Good timber harvest practices can control an epidemic but poor practices can create or intensify an outbreak.

This report examines Tolko’s management of the Douglas-fir bark beetle outbreak, its harvest practices, and if it complied with requirements for ungulate winter range.
