Abstract
Mountain pine beetle was the main problem in the Cariboo District, killing lodgepole pine in numerous areas. Western spruce budworm defoliated Douglas-fir around Clinton and Big Bar Creek; 2-year-cycle spruce budworm lightly defoliated alpine fir in the MacKay River - Hendrix Lake area. Douglas-fir trees killed by Douglas-fir beetle in 1976 were noticeable, but few 1977 attacks were found. Spruce beetle populations remained low in Bowron Lake Provincial Park, in white spruce blowdown. Red-band needle disease caused lodgepole pine discoloration, and leaf blights discolored trembling aspen and black cottonwood foliage.
