In order to obtain a quantitative...

Creator:: Summers, Richard P.
Abstract:: This study investigated the development of riparian zone vegetation at varying stand ages from one to 29 years following clearcut timber harvesting in western Oregon. Vegetation was classified into three layers for observation including the ground (less than 13 cm), the understory (less than 2.5 m), and the overstory (greater...

Creator:: Snider, Michael Duane
Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Creator:: Vanderwaal, James A.
Abstract:: An energy balance analysis was performed on each of four transplanted Douglas-fir [Pseudotsuga menziesii (Mirb.) Francol seedlings growing on two cutover sites in southwestern Oregon. The two sites were a clearcut and a partial-cut (shelterwood) side by side, with a pair of seedlings used on each site. One seedling of...
