Evaluation of mountain pine beetle infestations, Wolf Mountains, Crow Indian Reservation, Montana, 1973

Creator:: McGregor, Mark D., Kohler, Steve, Ferry, Gardner, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle reached epidemic levels in second-growth ponderosa pine stands on Bureau of Indian Affairs and private lands on the Crow Indian Reservation. Approximately 9,106 trees containing 420,266 merchantable board feet were killed from 1971 to 1973. This is about 24 percent of the merchantable ponderosa pine in stands...

Potential for the pine butterfly defoliation on the Flathead Indian Reservation in 1973

Creator:: Bousfield, Wayne E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The pine butterfly, Neophasia menapia Feld., has been at epidemic levels in the Bitterroot and Missoula valleys for the past 2 years (Ciesla et al. 1971) (Bousfield and Meyer 1972). Several reports of conspicuous pine butterfly flights on the Flathead Indian Reservation prompted an evaluation of the potential for pine...

Potential defoliation in 1979 from a ponderosa pine needle miner on the Flathead Indian Reservation and Missoula Valley, Montana

Creator:: Tunnock, Scott, Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A needle miner, Coleotechnites sp., defoliated approximately 3,100 acres of ponderosa pine, Pinus ponderosa Laws. on the Flathead Indian Reservation, Montana, during 1978. Three other small areas in the Missoula Valley were infested also. Overwintering populations of larvae are low; thus, light defoliation is expected in 1979 in presently infested...

Abstract:: Epidemic levels of the pine butterfly, Neophasia menapia (Felder and Felder) have been evident in ponderosa pine stands in the Bitter Root Valley since 1969. Evaluations of this infestation were initiated in 1970 to assess overwintering egg populations at 20 locations within the infestation (Ciesla et al. 1971). Defoliation was...
