Creator:: Widner, Gregory L.
Abstract:: Summer low flow characteristics of six forest streams in Northeast Oregon were examined using long term streamflow records. Time series and trend analysis revealed highly significant (alpha=O.O1) increasing trends in summer low flow over the period of record on four of the selected streams, and significant (alpha=O.05) year-to-year dependence on...

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...

Creator:: Zeb, Aurang
Abstract:: Characteristics of low flows of nine streams in eastern Oregon were explored using long-term streamflow records. Year-to-year dependence of low flows is highly significant for streams in the Blue Mountain and the southeastern Oregon regions. Low streamflows increased over the period of record for seven of the selected streams. Flow...

Creator:: Long, Barry A.
Abstract:: Research was conducted in the Oregon Coast Range to address the concern that conversion of large diameter old-growth forests to small diameter second-growth forests would lead to reduction of large woody debris in adjacent stream channels. The objective of the study was to quantify spatial trends in large woody debris...

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:: Carlson, Joan Y.
Abstract:: This study describes streams in the Blue Mountains and Wallowa Mountains of Northeastern Oregon in order to characterize the interactions between the terrestrial and aquatic ecosystems and to determine how logging affects those relationships. Five stream reach pairs, each consisting of an undisturbed reach and a similar reach flowing through...
