Forest Service. Northern Region. Forest Environmental Protection, United States. Forest Service. Northern Region. State & Private Forestry, Hamel, Dennis R. 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.

From 1974 to 1976 approximately 19,000 trees with an estimated volume of 10,210 cu m were killed. Based on buildup ratios, stand structure, size of trees, and residual green stand, it is predicted that 5,756 trees will be killed in 1977. Three management alternatives are discussed and selective logging is recommended.

Northern Region. State & Private Forestry Mountain pine beetle populations increased to epidemic levels on the Kootenai National Forest in 1972. Nearly 397,000 trees containing almost 32 million board feet have been killed. More than 84,000 trees will probably be killed in 1978. Infestation has the potential to intensify in high hazard stands, and some increase may occur in stands of low and moderate hazard. Potential losses can be reduced through an accelerated program of (1) sanitation salvage cutting and (2) silvicultural management. High-hazard stands should receive first priority.

State & Private Forestry, McGregor, Mark D. Mountain pine beetle populations began building in the Kootenai National Forest in 1972. Infestations now encompass an estimated 48,599 acres of lodgepole pine type and 615 acres of ponderosa pine type. Approximately 25 percent of the high-risk stands, 17 percent of the moderate-risk, and less than 1 percent of the low-risk stands are infested. Newly attacked trees averaged 10 per acre. Infestations have the potential to intensify in high-risk stands, with some increase in moderate- and low-risk stands. Predicted trends, plus management alternatives to prevent and/or reduce infestation severity, are discussed.
