Mark record


Infestations of mountain pine beetle killed an estimated 85,000 lodgepole pine trees over 15 800 ha (39,500 acres). The incidence of Douglas-fir beetle continued to decline. Two-year-cycle spruce budworm caused moderate defoliation of Engelmann spruce, white spruce and alpine fir in the Hendrix Lake to Bowron Lake regions of the District. Spruce beetle infested windfall white spruce at Bowron Lake. Western spruce budworm occurred in two areas in the District.

High winds caused sheet windfall on 200 ha (500 acres) at Bowron Lake Park. Other disease problems included dwarf mistletoe and a Douglas-fir needle rust.
