Creator:: Armlovich, David
Abstract:: This study looked at the soil compaction effects resulting from a cut-to-length harvest system on an area in the western Cascade Range of Oregon. The cut-to-length harvest system is a mechanized system in which trees are fell, deliinbed, and bucked into short log lengths by a mechanical harvester. Logs are...

Creator:: Farnsworth, Blake Templeton
Abstract:: This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography. This report on the pursuit of...

Creator:: Alley, David
Abstract:: This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

Creator:: Campbell, Lewis
Abstract:: An increase in frequency and severity of hot, dry summers has been associated with a dramatic shift in the coniferous forests of western Oregon’s valleys, especially on the privately-owned properties along the low-elevation edges of these valleys. Various conifer species, including Douglas-fir (Pseudotsuga menziesii), are declining in these forests, leaving...

Creator:: Allen, Marganne Mary
Abstract:: Soil bulk density and disturbance were measured before and after a commercial thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear densimeter was used to measure bulk density at four and eight inches....
