D.; Mann, John W.; Oregon State University. Forest Research Laboratory<br/><br/>Description: Clearcut and shelterwood reproduction methods are both important, silviculturallyviablereforestation tools for southwest Oregon. The ecology of local forests lends itself to thesuccessful application of either method, in most cases; thus, choice of method is typicallybased on land management objectives, which integrate social and resource values,economics, and administrative, political, and regulatory considerations. This reportsummarizes the available research and experience information base for the two methodsso that ecological, operational, and economic trade-offs can be better understood. Mostof the information focuses on planted Douglas-fir, although material on natural regenerationand other species also is presented. http://hdl.handle.net/1957/7969 Title: Questions about optimal bucking<br/><br/>Authors: Olsen, Eldon D.; Oregon State University. Forest Research Laboratory<br/><br/>Description: A compilation of Oregon State University research work on computer-aided crosscutting(bucking) of trees into logs. Major considerations for deciding whether to adoptoptimal bucking and steps to implement it are described. The bulletin references fieldstudies which evaluated and tested prototype optimal bucking systems. http://hdl.handle.net/1957/7968 Title: The market for waterfowl hunting on private agricultural land in western Oregon<br/><br/>Authors: Rasker, Ray; Cleaves, David; Johnson, Rebecca L., 1955-; Oregon State University. Forest Research Laboratory<br/><br/>Description: Trends in fee hunting in Oregon are examined, with particular emphasis onwaterfowl in the western part of the state. Farmers with potential or existingwaterfowl habitat in western Oregon were surveyed about their views on managingtheir lands for waterfowl. As incentives to such practices, they listed the financialreturns from leasing access to hunting, aesthetic appreciation of waterfowl, andpersonal enjoyment from waterfowl hunting. As deterrents, they listed negativeattitudes toward hunters and concerns over lawsuits by hunters. They also identifieddamage to crops by waterfowl as a source of friction between wildlife agenciesand landowners. http://hdl.handle.net/1957/7967 Title: Diameter growth equations for fourteen tree species in Southwest Oregon<br/><br/>Authors: Hann, David W.; Larsen, David R.; Oregon State University. Forest Research Laboratory<br/><br/>Description: Equations are presented that predict individual-tree 5-year diameter growth,outside bark, for 14 tree species in southwest Oregon. The data used to develop theequations came from 19,245 trees sampled from 391 stands in the study area. Theseequations express diameter growth as a function of diameter at breast height, crownratio, site index, total stand basal area, and stand basal area in trees with diameterslarger than the subject tree's diameter. The parameters of the equations wereestimated by using weighted, nonlinear regression.
