An assessment of dwarf mistletoes in Montana

Creator:: Dooling, Oscar J., Eder, Robert G., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Dwarf mistletoes reduce tree height and diameter, and thereby cause a reduction in volume production. We estimate that volume reduction in Montana is about 33.2 MM cubic feet per year. Mistletoe effects are problems in some areas because of the demands we have placed on the Forests for goods and...

Evaluation of diseases within selected stands on the Priest River Experimental Forest, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Three stands along Benton Creek within the Priest River Experimental Forest, Idaho, were surveyed for diseases using previously established timber inventory plots and sample trees. These surveys provided information to aid in formation of silvicultural prescriptions by CEFES (Continuing Education in Forest Ecology and Silviculture) students. Diseases were quantified at...

Natural mortality in a Douglas-fir tussock moth infestation in Idaho, 1974

Creator:: Tunnock, Scott, McGregor, Mark D., Lood, Rudolph C., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mortality from various causes was recorded in a Douglas-fir tussock moth, Orgyia pseudotsugata McD., outbreak southeast of Coeur d'Alene, Idaho, in 1974. Observations began June 27 when about 50 percent of the larvae were second instars and continued until pupation. Within a 35-day period, there was a 93 percent average...

Establishment report : permanent plots to evaluate the effects of Armillaria root disease in precommercially thinned stands

Creator:: Byler, James W., Stewart, C. A., Hall, L. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Methods used to establish permanent plots in precommercially thinned and unthinned stands to monitor root disease development are described. Plots were established in 22 Armillaria-infested stands in northern Idaho and western Montana. The proportion of trees dead and infected was significantly higher for planted than for natural regeneration at the...

An evaluation of cone and seed insects in selected seed production areas in Region 1 : progress report II

Creator:: Dewey, Jerald E., Jenkins, Michael J., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Insect damage was extensive to Douglas-fir, ponderosa pine, western white pine, and western larch cones at most seed production areas surveyed in 1979. From 70 to 100 percent of the cones from several collecting periods were injured. Moderate damage (40-70 percent of cones injured) occurred to Douglas-fir, ponderosa pine, western...
