Abstract

The summer of 1975 was much cooler than average with above normal rainfall. Mountain pine beetle was the most important insect pest in the District, killing an estimated 140,000 lodgepole pine trees. Douglas-fir beetle declined and, except for some minor defoliation by two-year-cycle spruce budworm, there were no other significant insect problems.

Globose gall rust, stem rusts, and dwarf mistletoe were the most prominent diseases.
