| dc.description |
An aerial survey during 1974 revealed approximately 5,000 acres of
various degrees of Douglas-fir tussock moth, Orgyia pseudotsugata McD.,
defoliation in the lower Flathead Valley. An egg mass survey was made
in September to determine the potential for damage in 1975. Based on
new egg mass densities, significant defoliation may occur on 2,880
acres. |
