Status of mountain pine beetle, Kootenai National Forest, Montana, 1979

Creator:: McGregor, Mark D. and United States. Forest Service. Northern Region. State & Private Forestry
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...

An evaluation of a developing mountain pine beetle infestation in Centennial Valley, Montana, 1979

Creator:: Gibson, Kenneth E., McGregor, Mark D., Bennett, D. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The mountain pine beetle infestation on Bureau of Land Management lands in Centennial Valley has increased from about 500 acres in 1977 to more than 7,000 in 1979. Average number of trees per acre killed has more than quadrupled, increasing from 9.8 in 1977 to 47.8 in 1979. Predictions for...

Mountain pine beetle infestation in ponderosa pine on Crow/Northern Cheyenne Indian Reservations, Montana, 1984

Creator:: Gibson, Kenneth E., McGregor, Mark D., Oakes, Robert D., and United States. Forest Service. Northern Region
Abstract:: The mountain pine beetle infestation existing on the Crow Indian Reservation (IR) since the early 1970's, and later developing principally in the western portion of the Northern Cheyenne IR, continued into 1984. Survey results indicate the infestation is still building on both Reservations. To help develop beetle management strategies appropriate...

Demonstration of the effectiveness of basal area cutting to reduce tree killing by the mountain pine beetle in ponderosa pine, Crow and Northern Cheyenne Indian Reservations, Montana, 1984 : establishment report

Creator:: Gibson, Kenneth E., McGregor, Mark D., Amman, Gene D., and United States. Forest Service. Northern Region
Abstract:: During 1984, a demonstration project was established on the Crow and Northern Cheyenne Indian Reservations to determine the effectiveness of basal area cutting in second-growth ponderosa pine stands to reduce losses to the mountain pine beetle. This project will help develop management strategies for susceptible stands in eastern Montana. Four...

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:: Douglas-fir beetle has increased to epidemic levels in mature-overmature Douglas-fir that has been top killed by western spruce budworm. About 42 trees per acre have been killed in an area at Lyon's Face and 36 trees per acre in other areas along the Madison River during the past 3 years....

Establishment report : permanent mountain pine beetle population trend plots, Montana, 1979

Creator:: Gibson, Kenneth E., McGregor, Mark D., Bennett, D. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Thirty permanent mountain pine beetle population trend plots were established in each of six areas in the state in 1979. Infestation levels ranged from 0 to 47.8 new attacks per acre. The potential for increased mortality is considered high for all areas. Each area will be evaluated for 5 years...
