Evaluation of mountain pine beetle infestation, Lap, Cool, and Caribou Drainages, Yaak District, Kootenai National Forest, 1976

Creator:

Hamel, Dennis R., Oakes, Robert D., and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Mountain pine beetle infestations developed to epidemic level in lodgepole pine stands on the Yaak District in 1972. Approximately 56,282 trees were killed from 1973 to 1975. By 1975, 2,068 ha were infested. This increased to 7,138 ha in 1976, representing a threefold increase. Current infestation occurs on 13 percent...

Evaluation of a mountain pine beetle infestation, Jack Creek Drainage, Madison District, Beaverhead National Forest, Montana, 1976

Creator:

Hamel, Dennis R., McGregor, Mark D., Oakes, Robert D., and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Mountain pine beetle populations developed to epidemic level in lodgepole pine stands in 1973. Approximately 426,355 trees were killed on 3,433 hectares in 1976. Infestations are expected to intensify in areas of current infestation and develop in uninfested stands. It is predicted that 1,722,288 trees will be killed in 1977....

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...

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...

Evaluation of the mountain pine beetle infestation, Blackfeet Indian Reservation and east side Glacier National Park (Montana, 1979)

Creator:

McGregor, Mark D., Gibson, Kenneth E., and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Mountain pine beetle infestation was detected in stands on the east side of Glacier National Park and the adjacent Blackfeet Indian Reservation in 1979. Infestation in the Park now encompasses an estimated 215,882 acres. About 200 acres are infested on the reservation. In areas sampled, number of trees killed per...

Status of mountain pine beetle infestations, Kootenai National Forest, Montana, 1977

Creator:

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

Abstract:

Mountain pine beetle populations increased to epidemic levels on the Kootenai National Forest in 1972. Nearly 397,000 trees containing almost 32 million board feet have been killed. More than 84,000 trees will probably be killed in 1978. Infestation has the potential to intensify in high hazard stands, and some increase...

Creator:

McGregor, Mark D., Hamel, Dennis R., Kohler, Scott, and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Mountain pine beetle populations developed to epidemic level in Glacier National Park in 1972. Buildup ratio of old to newly attacked trees was 1:1.8 from 1976 to 1977. More than 12 million trees are infested on 142,871 acres. Buildup ratio is expected to exceed 1:3 from 1977 to 1978. Management...

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...

Creator:

Gibson, Kenneth E., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

This report contains a brief history of selected mountain pine beetle infestations and the potential for infestations in high hazard stands on the Tally Lake Ranger District. Management alternatives to lessen the severity, or reduce the possibility, of infestations are discussed.

Potential for infestation by mountain pine beetle in lodgepole pine stands, Hungry Horse District, Flathead National Forest, 1977

Creator:

Hamel, Dennis R., Oakes, Robert D., Hothem, R., and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Ground surveys on the Hungry Horse District indicate a potential for mountain pine beetle infestation in lodgepole pine. Based on elevation-latitude, mean d.b.h. and phloem thickness, and age, stands were given a susceptibility classification of high risk. An infestation in Glacier National Park may provide the beetle source. Management alternatives...
