A hierarchical stream habitat classification system: development and demonstration

Creator:: Frissell, Christopher A.
Abstract:: Classification of Streams and stream habitats is useful for research involving establishment of monitoring stations, determining local impacts of land use practices, generalization from site-specific data, and assessment of basin-wide, cumulative impacts of human activities on streams and their biota. This thesis presents a framework for a hierarchical classification system,...

Spatial and temporal dynamics of sediment and wood in headwater streams in the central Oregon Coast Range

Creator:: May, Christine L.
Abstract:: Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...

Ecology of aquatic habitats associated with stream margins

Creator:: Moore, Kelly M. S.
Abstract:: The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

The source area for coarse woody debris in small streams in western Oregon and Washington

Creator:: McDade, Mary Helen
Abstract:: Large organic debris has important biological and physical roles within the stream ecosystem. In order to determine the source area of large organic debris in streams, thirty-nine streams in the Cascade and Coast Ranges of Oregon and Washington were sampled. The distance from point-of-origin to channel was measured for thirty...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Cumulative effects of land use on salmon habitat in southwest Oregon coastal streams

Creator:: Frissell, Christopher Andrew, 1960-
Abstract:: As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...

The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Creator:: Takahashi, Mayumi
Abstract:: This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) examine if the vegetation composition and structure of the riparian forest varied among channel-reach morphologies, 2) examine...

Empirical modeling of windthrow occurrence in streamside buffer strips

Creator:: Drake, Timothy P.
Abstract:: Streamside buffer strips provide numerous benefits to stream ecosystems. The buffer strips create shade, provide shelter for wildlife, act as barriers to logging debris during and after timber harvest, and serve as a continued source of large woody debris. Quantifying woody inputs resulting from windthrow provides managers with estimates for...

Relationships among juvenile anadromous salmonids, their freshwater habitat, and landscape characteristics over multiple years and spatial scales in the Elk River, Oregon

Creator:: Burnett, Kelly M.
Abstract:: Research on the distribution of juvenile salmonids in streams has been dominated by studies examining small areas over short periods. However, information relevant to freshwater influences on population persistence is likely to derive from longer-term, multi-scale studies. Relationships were examined among juvenile anadromous salmonids, their freshwater habitat, and landscape characteristics...
