Creator:: Zaborske, Richard R.
Abstract:: The use of mechanized harvest equipment has been increasing as an economical method to harvest small diameter timber. While the use of this equipment is increasing, little is known about associated soil compaction. In particular, little information exists on soil compaction caused by feller--bunchers. This study measured soil compaction caused...

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

Full Text:: Impacts on Coarse Woody Debris and Channel Form in Central Oregon Streams Abstract approved: Dr. Henry

Creator:: Chesney, Charles J.
Abstract:: This study focused on extensive soil mass movement occurrence in the Willamette National Forest of western Oregon and on intensive measurements of some physical and biological changes in streams following debris torrents. Debris torrents are a rapid movement of water-charged debris confined to steep headwater channels. The frequency (events/ha/yr) of...

Creator:: Heimann, David C.
Abstract:: This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...
