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...

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...

Influences of riparian canopy on aquatic communities in high desert streams of eastern Oregon

Creator:

Tait, Cynthia K.

Abstract:

Because riparian canopy controls most energy inputs to stream ecosystems, it directly affects the structure of aquatic food webs and the ecological processes that govern interactions among trophic levels. This study addresses the interdependence among riparian canopy, benthic community structure, and the carrying capacity of high desert streams for salmonid...

Dissertation
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...

Dissertation
Historical change in channel form and riparian vegetation of the McKenzie River, Oregon

Creator:

Minear, Paula J.

Abstract:

This study examined channel structure and position and riparian vegetation and land use on the upper 70 km of the McKenzie River, Oregon in the 1940s, compared the 1940s conditions to present conditions, and explored the processes driving change in this system and the implications for aquatic habitat. The hydrologic...

Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:

Ursitti, Victoria L.

Abstract:

Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...
