Abstract

A study of lumber grade yields and recovery factors from dwarf mistletoe-infected lodgepole pine trees in British Columbia indicated that there were no differences of practical importance compared with yields and quality recovered from a control group of noninfected trees.

Mistletoe infestation was confined largely to the crown portions of infected trees, with few instances of lower bole attack. Although there were no differences in visual grade yields from infected and noninfected samples, there was good evidence of growth retardation in the infected stand.
