Evaluation of multistage sampling techniques to measure lodgepole pine mortality caused by mountain pine beetle in Montana, 1979

Creator:: Bennett, D. D. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A pilot survey was conducted to evaluate the effectiveness of using multistage sampling techniques to measure annual and cumulative mortality on a State-wide basis with acceptable statistical reliability, timeliness, and cost. Within the State of Montana, aerial surveys showed about 986,000 acres of lodgepole pine infested with mountain pine beetle....

Impact of fluorides and insects on radial growth of lodgepole pine near an aluminum smelter in Northwestern Montana : a preliminary inquiry

Creator:: Carlson, Clinton E., Hammer, William P., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A study was conducted in summer of 1973 to assess impact of fluoride-insect damage on radial growth of lodgepole pine near the Anaconda Aluminum Company at Columbia Falls, Montana. Statistically significant growth losses attributed primarily to the effects of fluorides were found in 40 14 of 17 unmanaged stands for...

Dwarf mistletoe loss assessment in east side Northern Region national forests

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...

Biological notes on the emergence of mountain pine beetle and associates from lodgepole pine, Gallatin Ranger District, Gallatin National Forest, Montana, 1975

Creator:: Hamel, Dennis R., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Emerged beetles were first collected July 17 and peak emergence occurred between August 10 and 26, 1975. Density of attacks averaged four per 0.5 ft. 2 (0.05 m2). Parent to brood ratio was 1:4.6. Thirteen associate insects, representing six families of Coleoptera and one of Diptera, were recovered. Associates included...

Evaluation of mountain pine beetle infestations, Gallatin Ranger District, Gallatin National Forest, Montana, 1975

Creator:: McGregor, Mark D., Hamel, Dennis R., Lood, Rudolph C., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle has occurred at epidemic level in lodgepole pine stands in the west Gallatin River drainage since 1969. Infestation now encompasses about 5,500 acres. Since 1969, approximately 463,212 trees, with an estimated volume of 20,529,244 board feet have been killed. Approximately 69 percent of the stands on the...

Evaluation of mountain pine beetle infestations, Lazier and Meadow Creek drainages, Plains District, Lolo National Forest, Montana, 1975

Creator:: McGregor, Mark D., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle reached epidemic levels in the Lazier-Meadow Creek drainages on mixed ownership in 1972. A total of 118,486 trees with an estimated volume of 5,666,124 board feet was killed from 1972 through 1974. Presence of overstocked, mature, nearly pure lodgepole stands, coupled with favorable weather conditions, are believed...

Status of mountain pine beetle infestations, Glacier National Park, 1974

Creator:: McGregor, Mark D., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations reached epidemic levels on approximately 4,600 acres in Glacier National Park in 1972. Infested trees increased from 4.9 in 1972 to 10.9/acre in 1975. Majority of trees killed since 1972 were 12 inches d.b.h. and larger in size. Sufficient large diameter lodgepole pine exists to maintain...

Status of mountain pine beetle infestations, Yellowstone National Park, Wyoming, 1973

Creator:: Hamel, Dennis R., McGregor, Mark D., Berg, Malcolm J., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The mountain pine beetle infestation has been epidemic in lodgepole pine in Yellowstone National Park since 1966. Infestation boundaries have advanced steadily northward and eastward. The infestation now encompasses nearly one-half of the total Park area. Surveys indicate a decline in tree mortality the last 2 years. In 1970, an...
