Abstract

Western spruce budworm infestations, which persisted for the past several years in Douglas-fir stands in the southeastern part of the Vancouver Mainland section, subsided in 1978. Mountain pine beetle outbreaks, which killed large tracts of lodgepole pine in the Klinaklini River Valley, declined. Winter moth continued to cause heavy defoliation of urban forests in the Greater Victoria area. Gypsy moth was found for the first time in British Columbia, in the Vancouver area.

Drought injury in immature Douglas-fir stands was widespread on Vancouver Island and the Mainland. Douglas-fir dwarf mistletoe was found for the first time in coastal British Columbia, at Slesse Creek in the Chilliwack River Valley.
