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...

Status of mountain pine beetle infestation, Bozeman-Gallatin Ranger District, Gallatin National Forest, 1977

Creator:: McGregor, Mark D., Hamel, Dennis R., Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations developed to epidemic level on the Bozeman-Gallatin Ranger District in 1969. Approximately 146,000 acres are currently infested. Since 1969, over 350 MMBF have been killed. It is predicted that over 4 million trees could be killed in 1978. Infestation is predicted to intensify in high-hazard stands....

Status of mountain pine beetle infestation, Gallatin National Forest, 1976

Creator:: McGregor, Mark D., Hamel, Dennis R., Oakes, Robert D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle developed to epidemic level in lodgepole pine stands in 1969 on the Gallatin District and in 1970 on the Hebgen Lake District. Epidemic infestation occurs on 53,437 hectares. Infestations will intensify in most areas currently infested and develop in uninfested stands, and in excess of 2 million...

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....

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...

Status of mountain pine beetle infestations in second-growth ponderosa pine stands, Little Rocky Mountains, Fort Belknap Reservation, Montana, 1977

Creator:: Hamel, Dennis R. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle infestations in second-growth ponderosa pine developed in 1973 in the Little Rocky Mountains. In 1976, increasing numbers of attacked trees were observed. Current infestation intensity averages 7.1 trees per acre. Losses are expected to continue as long as stands remain overstocked and stagnated. Reduction of basal area...

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...

Status of mountain pine beetle infestation, Glacier National Park, 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 began increasing in Glacier National Park in 1970. Numbers of infested trees increased steadily from an average of 12 to 115 per hectare from 1972 to 1976. Total hectares of infestation have increased from 445 in 1972 to 40,419 ha in 1976. Predictive equations estimate a...
