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...

Permanent mountain pine beetle population trend plots : an update, 1981

Creator:: Gibson, Kenneth E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Six Montana areas in which permanent mountain pine beetle trend plots were established in 1979 were revisited in 1980. Results of the visit show infestation intensity decreased significantly in Centennial Valley, decreased slightly in the Madison River plot area, and increased almost threefold in the Murr Creek area. Beetle populations...

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....

Mountain pine beetle status update, Plains Ranger District, Lolo National Forest, 1979

Creator:: Gibson, Kenneth E., Bennett, D. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations increased in 1979 in the Thompson River drainage to levels predicted following the 1978 attack period. New attacks in 1979 averaged 27 per acre. Current estimates indicate another 25 percent of the remaining lodgepole pine could be killed in 1980.

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 mountain pine beetle infestation, Hebgen Lake Ranger District, Gallatin National Forest, Montana, 1978

Creator:: McGregor, Mark D., Bennett, D. D., Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations developed to epidemic level in 1970 on the Hebgen Lake Ranger District. Infested acreage increased from 78,000 in 1977 to 79,061 in 1978. More than 4 million trees (238 MMBF) were killed in 1978. Cold temperatures during December 1978 may cause a significant decline in the...
