Abstract:: Trends in fee hunting in Oregon are examined, with particular emphasis on waterfowl in the western part of the state. Farmers with potential or existing waterfowl habitat in western Oregon were surveyed about their views on managing their lands for waterfowl. As incentives to such practices, they listed the financial...

Abstract:: The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...

Abstract:: The production rates and costs of harvesting smallwood were determined for a small yarder (Koller K-300) operating under variable conditions: the size of the crew, the addition of a skidder to swing logs from the landing, and the type of harvest method-employed, either conventional or hot thinning (simultaneous felling and...

Abstract:: Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...

Abstract:: Research on skyline machines and techniques currently available for yarding smallwood is reviewed. Three categories of machines are discussed: used yarders (with a low initial cost) adaptable to smallwood, new and versatile yarders (with a high Initial cost) manufactured in the United States, and new, foreign-built yarders (with a low...

Abstract:: The Forest Engineering Department, Oregon State University, has evaluated several systems for thinning young timber stands on steep terrain. Stands averaged 35 to 40 years old and 25.4 to 35.6 cm (10-14 in.) dbh. Approximately 40 percent of the stems per hectare were removed in the thinning operations. This paper...
