Incidence of wood borer activity in green ash windbreak plantings in North Dakota

Creator:: Tunnock, Scott, Tagestad, Arden, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An evaluation was made during midsummer 1972 to measure damage by the carpenterworm, Prionoxystus robiniae, and the ash borer, Podosesia syringae, to green ash in windbreaks in North Dakota. Intensity of infestation was determined in four land resource areas and four age classes of windbreaks. Of the 96 windbreaks examined...

Creator:: Flavell, Thomas H., United States. Forest Service. Northern Region. Forest Insect and Disease Management, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Green ash windbreaks in North Dakota were surveyed in 1972 and 1976 to determine the incidence of attacks by the carpenterworm, ash borer, and other stem-infesting wood borers. Windbreaks were stratified by age and geographic region. In 1976, about 3.1 percent of the green ash trees in North Dakota had...

Creator:: Tunnock, Scott, Hard, John S., Karch, Tom, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The forest tent caterpillar, Malacosoma disstria Hbn., began defoliating trembling aspen stands, Populus tremuloides Michx., in 1976 in the Turtle Mountains of North Dakota. Heavy defoliation was scattered through about 150,000 acres in 1978. Pupal mortality from parasites and disease was almost 100 percent in cocoons on understory shrubs and...

Pathogenic Fusarium on spruce seed from the Towner Nursery, North Dakota

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Five seedlots of Colorado blue spruce and three seedlots of Black Hills spruce were sampled for Fusarium contamination. All seedlots contained some seed and/or debris with Fusarium. Levels of contamination were greatly reduced by treating seed with running water rinses for 48 hours or with chemical sterilants such as sodium...

Effects of kokanee (Oncorhynchus nerka) redd superimposition on bull trout (Salvelinus confluentus) reproductive success in the Deschutes River Basin, Oregon.

Creator:: Weeber, Matthew A.
Abstract:: Oregon's only remaining non-reservoir population of adfluvial bull trout (Salvelinus confluentus) is found in Odell Lake, in the headwaters of the Deschutes River. The population size is unknown, but appears to be quite small. Limited spawning and rearing habitats, combined with the effects of introduced species and other anthropogenic changes...
