Interim report of activities from June 1, 1975 -- May 30, 1976 Author: Carlson, Clinton E., United States. Forest Service. Northern Region. State & Private Forestry, Tourangeau, Phillip, Gordon, Clarence C. Baseline data for the first year of a two-year study to assess the current status of ponderosa pine stands in southeastern Montana relative to coal-fired electric power development are presented. Sixteen permanent plots in pine stands were established in eastern Montana, South Dakota, and Wyoming. Several characteristics believed to be sensitive to future sulfur dioxide and fluoride pollution from the power complex were measured on ten trees from each site. Average fluoride concentration in foliage was 1.48 parts per million (ppm), and total sulfur was 483 ppm. Total chlorophyll was .657 mg/gm (fresh wt.) in current needles, .930 mg/gm in year-old needles, 1.016 mg/gm in 2-year old needles, and 1.016 mg/gm in 3-year old foliage. Average foliar water content was 48.9 percent, and mean needle length was 125.3 mm. Needle retention varied between 97-84 percent, depending on internode age. Average fascicular cross-sectional area was 2.1 sq. mm. A number of different insects, fungi, and abiotic factors contributed to slight yellowing and browning of needles, including elegans pine weevil, basal side, various defoliators, and weather factors. Average total necrosis (tissue death) due to the sum of all these factors was less than 7 percent. Measurements of airborne reactive sulfur and fluoride by static plate techniques were negative. This, combined with the very low foliar concentration of sulfur and fluoride, establish the study area as virtually pollution free as of 1975. Additionally, comparisons between the baseline study area and known polluted sites throughout the United States indicate that the polluted sites differ significantly in regard to then pine characteristics measured, and that the degraded pine conditions in the polluted areas are due to airborne sulfur and fluoride concentrations similar to those expected in the near future from the Colstrip power generating facilities. It is anticipated that the ponderosa pine in the study area will be affected. This baseline study will be a convenient, if not necessary, document with which to compare future data in order to detect pollution insults on the pine forests in southeastern Montana.

  Citation × Citation Citation Abstract Copy Title: Status of Douglas-fir bark beetle, Madison Ranger District, Beaverhead National Forest, 1982 Author: United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management, Dooling, Oscar J., McGregor, Mark D., Oakes, Robert D. Douglas-fir beetle has increased to epidemic levels in mature-overmature Douglas-fir that has been top killed by western spruce budworm. About 42 trees per acre have been killed in an area at Lyon's Face and 36 trees per acre in other areas along the Madison River during the past 3 years. Sufficient top kill has now occurred that an increase is predicted in Douglas-fir beetle activity for several years in defoliated and top-killed stands. An aerial application of MCH is recommended to protect stands (important for wildlife habitat and in critical viewing areas) from further loss. Stand hazard rating and management, both silviculture and aerial spraying of budworm-infested stands, are recommended where economically and environmentally feasible to prevent further loss. Rapid salvage of windthrown Douglas-fir is recommended to reduce the potential buildup of Douglas-fir beetle populations.

  Citation × Citation Citation Abstract Copy Title: Conifer root diseases on the Kootenai National Forest, Montana Author: United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management, Stewart, C. A., James, Robert L. A survey for incidence and distribution of root diseases was conducted on the Kootenai National Forest using timber inventory subcompartments as primary sample units. Root diseases were located within 23 of 75 sampled subcompartments. At least 1.1 percent of the commercial forest lands within the Forest are infested with root diseases. Large active disease centers occupy more than 1,550 ha (3,830 acres) of forest land. Major pathogens encountered were Phellinus weirii, Armillaria mellea, and Phaeolus schweinitzii. P. weirii was found mostly within the Cabinet Ranger District; other pathogens were distributed throughout the Forest. Bark beetles often infested root-diseased trees. Most root disease was found within the Pseudotsuga menziesii, Abies grandis, and Tsuga heterophylla series of habitats. Management procedures for reducing losses in root-diseased stands are discussed. Title: Conifer root diseases on the Kootenai National Forest, Montana Author: United States. Forest Service.
