Book excerpt: 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.

This book was released on 1978 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1978 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sequential sampling plan is described for identifying tussock moth populations which, at a maximum expected rate of increase, could be within 1 year of outbreak status. The plan uses a new technique of sampling early larvae by the nondestructive examination of lower crown foliage. Larvae at inconspicuous low densities are classified into relatively low or high categories by their frequency of occurrence on foliage samples. The sampling plan is applied independently on individual plots to classify the density of each plot. It is an appropriate method for quickly screening suboutbreak populations in ground evaluation surveys.
