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...

Insect and disease surveys of some Inland Empire Tree Improvement Cooperative test plantings

Creator:: Dooling, Oscar J., Gibson, Kenneth E., and United States. Forest Service. Northern Region
Abstract:: Potential problem pests found were Armillaria root disease, pocket gopher, western pine shoot borer, and white pine blister rust. Early detection of problem pests allows management actions to be taken if needed to prevent serious impacts. Unit managers should check the areas periodically and call on pest management specialists to...

Effects of radio frequency waves on fungal colonization of styroblock containers

Creator:: James, Robert L., Trent, Andy, United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Fungal pathogens tend to accumulate within styroblock containers, which are reused to produce successive crops of container-grown seedlings. Most nurseries treat reused containers by immersing them in hot water for varying time periods. The efficacy of radio frequency waves (RFs) to reduce levels of selected groups of fungi within styroblock...

Occurrence of Fusarium on leach pine cells from the USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., Gilligan, Carma J., and United States. Forest Service. Northern Region
Abstract:: Three hundred fifty Leach pine cells used to grow containerized conifer seedlings at the USDA Forest Service Nursery in Coeur d'Alene, Idaho, were sampled for Fusarium and Trichoderma colonization. Cells were either sampled prior to or after cleaning. Cleaning reduced Fusarium colonization from 86 percent of the cells to about...
