Mountain pine beetle infestations in the Snell Creek and Warland Peak areas were evaluated in October 1975. Based on current buildup ratios, tree diameter distributions, stand composition and phloem thicknesses, there appears to be limited opportunity for epidemic potential in either area. Management alternatives are discussed. Selective logging is recommended to further decrease epidemic potential and reduce the infestations to endemic status.

Forest Service. Northern Region. State & Private Forestry An infestation of a defoliating weevil, Magdalis gentilis LeConte, was reported in July by Hank Manning, Judith Ranger District forester, Lewis and Clark National Forest. The infestation occurs in precommercially thinned stands of lodgepole pine, Pinus contorta var./atifblia Engelm. in the Moose Creek drainage. Although damages caused by M. gentilis are relatively uncommon in Region 1 forests, the current problem has existed since 1965 (Fellin 1973). An evaluation of the infestation was made August 14, 1974.

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 are discussed and long-term management goals are recommended.

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 trees could be killed in 1977. Salvage logging to remove brood trees and silvicultural management to reduce average stand diameter below 20.3 cm d.b.h. are recommended to manage the infestation.
