Book excerpt: Excerpt from Growth of Regeneration Defoliated by Spruce Budworm in Idaho The term dieback refers to top-kill from which trees can recover to produce a merchantable product above the point of top-kill. Top-kill, as used in the Prognosis Model (wykoff refers to a truncated height above which no merchantable volume will accrue.

Download or read book Stem Volume Losses in Grand Firs Topkilled by Western Spruce Budworm in Idaho written by George T. Ferrell and published by . This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mature grand firs (Abies grandis [Dougl. ex D. Don] Lindl.) were sampled in two stands, one cutover and one virgin, in the Little Salmon River drainage in west-central Idaho, to estimate stem volume losses associated with topkilling. Damage to the stands resulted from three outbreaks of western spruce budworm (Choristoneura occidentalis Freeman) in 1922-30, 1952-55, and 1969-78. Stems of the firs were dissected and examined for reductions in height and radial growth, stem deformities, and decay associated with topkills. Merchantable volume losses (to a minimum 4-inch diameter top) were calculated for each outbreak. Greatest volume loss was associated with tops killed by the 1922-30 outbreak. Loss varied widely among the trees and stands sampled. In the cutover stand, which received a sanitation cutting in the late 1960's, firs topkilled by the 1922-30 outbreak averaged losses of 9.5 ft3 (0.3 m3), amounting to 11.1 percent of merchantable stem volume. In the vigin stand, losses averaged 26.3 ft3 (0.3 m3) or 20.5 percent of stem volume. Topkill-associated decays, caused mainly by Indian paint fungus (Echinodontium tinctorium Ell. and Ev.) were responsible for most of this loss. Smaller volume losses were recorded in firs topkilled by the 1952-55 outbreak. Losses per tree averaged 3.3 ft3 (0.1 m3) or 5.4 percent in the cutover stand, and 0.5 ft3 (0.02 m3) or 0.3 percent in the virgin stand. These losses resulted mainly from height growth reductions rather than decay. No merchantable volume losses were recorded for the 1969-78 outbreak.

This book was released on 1991 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.
