  Citation × Citation Citation Abstract Copy Title: Predators of hemlock woolly adelgid in northwestern Oregon Author: Byrkit, Maggie K. Hemlock woolly adelgid, Adelges tsugae Annand, is a serious threat to eastern hemlock, Tsuga canadensis Carriere, in the eastern United States. Infestations of A. tsugae are spreading rapidly and tree mortality caused by the insect is increasing yearly. As part of an integrated management approach, a classical biological control program is being implemented in eastern forests impacted by A. tsugae. Two insect predators have been released as control agents, but their impact on A. tsugae to date is uncertain. A priority of the USDA Forest Service Forest Health Techhology Enterprise Team (FHTET) is to identify additional potential control agents. The Pacific Northwest, where A. tsugae inhabits western hemlock (T. heterophylla), was identified as a region to survey for adelgid predators. Thirty-one T. heterophylla infested with A. tsugae in northwestern Oregon were sampled monthly for predatory arthropods from April 2003 to April 2004. Adelges tsugae development was monitored. In September 2003 and March 2004, trees were sampled to determine A. tsugae density. Development of adelgids on study trees was similar to development observed in the eastern U.S., with differences in timing between 2003 and 2004. Trees infested with A. tsugae had only a small amount of defoliation. Small numbers of several predatory arthropod taxa were collected from A. tsugae infested branches, including Laricobius nigrinus Fender, coccinellid beetles, minds, other hemipterans, pseudoscorpions, earwigs and lacewings. The abundance of L. nigrinus appeared to be positively correlated to the density of A. tsugae. Title: Predators of hemlock woolly adelgid in northwestern Oregon Author: Byrkit, Maggie K.

  Citation × Citation Citation Abstract Copy Title: The valuation and use of site information for Douglas-fir reforestation in Western Oregon : a decision analysis Author: Schöne, Dieter Hans-Friedrich Existing forest site maps have been described as "invaluable tools" in forest management. Their, economic value potentially materializes as the summed advantage from better decisions in all phases of forestry. Via Bayesian decision analysis, this study establishes optimal use and economic value of site information for one facet of management only: The choice of an optimal planting density in Douglas-fir reforestation. Two case studies were undertaken in extremely different environments of Southwestern and Northwestern Oregon. The prior analysis is based on a review of existing ref3restation records and a simulation model. Optimal prior acts differ substantially from present policies. Their implementation may reduce expected costs by approximately $50 per acre. Based on ecological variables observed an 350 survival plots, prediction aids for first-year survival arid site class, the main sources of uncertainty,are established. Plant water relations, and particularly the available water capacity of soils, emerge as prime determinants of survival and productivity. During preposterior analysis, Bayes' strategy translates ecological knowledge directly into optimal managerial choices for specific site units. Site information is evaluated economically, based on prospective reduction of reforestation costs. Expected values of site information are relatively low and almost identical in both ownerships. In the Northwestern Oregon study, it is a rather uniform environment for reforestation which limits the value of information. In the very diverse environment of the Southwestern Oregon ownership, lower marginal costs for plantation establishment, and smaller opportunity losses set these limits. A larger potential value of site information is likely for activities with high marginal costs in Southwestern Oregon. Bayesian decision analysis emphasizes the duality of ecology and economics in forest management. Combined with a system of collecting and analyzing operational records, it resembles a traditional forestry approach to uncertainty: Biolley's control method. As an extended, economically, statistically and computationally refined equivalent of the control method, Bayesian decision analysis deserves a place in the theory of forestry and in practical management of our forests.

  Citation × Citation Citation Abstract Copy Title: A stratigraphic and geochemical investigation of ferruginous bauxite deposits in the Salem Hills, Marion County, Oregon Author: Hoffman, Charles William Year: 1981 Pacific Northwest ferruginous bauxite deposits have formed in four main areas of northwestern Oregon and southwestern Washington by laterization of flows of the Columbia River Basalt Group (CRBG). The deposits, averaging 36.3% Al2O3 , 31.8% Fe2O3 , and 5.9% Sio2, generally occur near the surface of hilltops in gently rolling areas. Two very different views have been advanced regarding the setting in which the deposits have formed. The first hypothesis calls for a blanket-type laterization by erosion of much of the original deposit upon uplift and dissection of the area.

  Citation × Citation Citation Abstract Copy Title: Crown profile equations for stand-grown western hemlock trees in northwestern Oregon Author: Hann, David W., Johnson, Gregory P., Marshall, David D. Crown profile equations were developed for stand-grown western hemlock (Tsuga heterophylla (Raf.) Sarg.) in northwest Oregon. The profile model uses a segmented approach, dividing the crown into an upper and lower portion at the point of the largest crown width (LCW). The model explains about 86% of the variation in crown width when LCW is known but only 66% when LCW is predicted using a model developed from a larger data set collected in the same area as the data for developing the crown profile models were collected. The model can be adjusted using measurements or predictions of LCW for western hemlock in other populations. Comparisons are made with the crown form of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Title: Crown profile equations for stand-grown western hemlock trees in northwestern Oregon Author: Hann, David W., Johnson, Gregory P., Marshall, David D.

These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers the effects of precipitation, season, method of wastes storage and application, die-off of the bacteria in storage, die-off of the bacteria on the land surface, infiltration of bacteria into the soil profile, soil characteristics, overland transport of bacteria (runoff), and buffer zones. The model is then applied to the Tillamook basin in northwestern Oregon to evaluate which waste management procedures significantly decrease bacterial pollution potential in agricultural runoff.
