Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

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...

The geomorphic significance of log steps in forest streams of the Oregon Coast Range

Creator:: Marston, Richard A.
Abstract:: A log step develops when large woody debris extends across the active channel, creating a change in the water surface elevation as the stream spills over the log step. By forming a series of vertical falls, log steps reduce the amount of potential energy available for conversion to kinetic energy...

Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:: Skaugset, Arne E.
Abstract:: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...

Response of terrestrial vertebrates to three silvicultural treatments in the Central Oregon Coast Range

Creator:: Chambers, Carol Louise, 1958-
Abstract:: Growing concerns over maintaining animal and plant biodiversity have led to significant changes in forest management policies in the Pacific Northwest. Silvicultural alternatives to clear cutting are being suggested to promote development, retention, or creation of late-successional features such as large trees, multilayered canopies, snags and logs. As alternative management...

Debris flow characteristics associated with forest practices in the central Oregon Coast Range

Creator:: May, Christine L.
Abstract:: Debris flows in the Pacific Northwest play a major role in routing wood and sediment stored on hillslopes and in first- through third-order channels to higher order channels and valley floors. Forest practices on steep, unstable slopes and removal of riparian trees along low-order streams can affect the frequency, magnitude,...

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Discharge and suspended sediment a paired watershed study examining the effects of contemporary forest harvesting in the Oregon Coast Range

Creator:: Hatten, Jeff, Segura, Catalina, Bladon, Kevin, Hale, Cody, Ice, George, and Stednick, John
Abstract:: Forest harvesting practices can expose mineral soils, decrease infiltration capacities of soils, disturb the stream bank and channel, and increase erosion and fine sediment supply to stream channels. To reduce nonpoint source sediment pollution associated with forest management activities and to maintain the high water quality typically provided from forests,...
