Book Synopsis Stem Volume Losses in Grand Firs Topkilled by Western Spruce Budworm in Idaho by : George T. Ferrell
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.

The report also helps to fulfill a congressional mandate (The Cooperative Forestry Assistance Act of 1978, as amended) that requires survey, monitoring, and annual reporting of the health of the forests. This report also provides information used in the annual Forest Insect and Disease Conditions in the United States report. Forestry technicians, conservation specialists, scientists, arborists, tree wardens, natural resource planners, and others involved in forest and wildlife protection would be interested in this report. Students pursuing coursework in natural resources management and forestry may also be interested in this primary source document.
