Evaluation of mountain pine beetle infestations, Thompson River Drainage, Plains District, Lolo National Forest, Montana, 1976

Creator:: McGregor, Mark D., Hamel, Dennis R., and Oakes, Robert D.
Abstract:: Mountain pine beetle developed to epidemic levels in lodgepole pine stands in the Thompson River drainage in 1971. Approximately 506,616 trees are infested on 4,444 hectares. Based on buildup ratios, infestations are expected to intensify; develop in uninfected stands; and kill about 1,763,024 trees in 1977. Salvage logging of infested...

Evaluation of Douglas-fir mortality from Douglas-fir beetle from 1982 through 1984 following MCH application

Creator:: McGregor, Mark D., Oakes, Robert D., Meyer, Hubert E., and United States. Forest Service. Northern Region
Abstract:: A granular controlled release formulation of 2 percent MCH was applied at 4.48 kg/ha to 76.9 ha of uninfested, windthrown Douglas-fir by helicopter with a modified aerial spreader of 1.12 m capacity in May 1982. Douglas-fir beetle population reduction was 96.4 percent by late June. With one exception, treated plots...

Abstract:: Mountain pine beetle populations began building in the Kootenai National Forest in 1972. Infestations now encompass an estimated 48,599 acres of lodgepole pine type and 615 acres of ponderosa pine type. Approximately 25 percent of the high-risk stands, 17 percent of the moderate-risk, and less than 1 percent of the...
