Excerpt from Tree Mortality and Top-Kill Related to Defoliation by the Douglas-Fir Tussock Moth in the Blue Mountains Outbreak The data indicate that Douglas-fir suffers proportionally more tree mortality than grand fir. Douglas-fir comprises about 20 percent of the stand on the plots, but the total percent stand mortality almost equals grand fir mortality.

Excerpt from Radial Growth in Grand Fir and Douglas-Fir Related to Defoliation by the Douglas-Fir Tussock Moth in the Blue Mountains Outbreak A recent extensive outbreak in the Blue Mountains of Oregon and washington offered the opportunity to study tree damage resulting from defoliation by extremely dense populations of dftm. The objective of studies begun in 1972 was to use defoliation intensity in 1972 and 1973 as a predictor of tree damage during and after the outbreak. Two important forms of damage, tree mortality and top - kill, have already been summarized from this study (wickman l978a). The three forms of damage have also been mathematically represented in the dftm outbreak model (overton and Colbert This paper summarizes the effects of defoliation on radial growth during and immediately after the outbreak.

Download A Case Study of a Douglas-fir Tussock Moth Outbreak and Stand Conditions 10 Years Later Book in PDF, ePub and Kindle
Tree damage occurring immediately after an outbreak of Douglas-fir tussock moth, Orgyia Pseudotsugata McD., and stand conditions 10 years later are described. Because of increased radial growth and ingrowth in the 10-year postoutbreak period, good evidence indicates that tree damage caused by the tussock moth may not be as severe in the overall stand dynamics as previously pictured. The insect probably plays a key role as a phytophagous regulator of primary production in some second-growth white fir stands in California and elsewhere.
