Stream habitat classification and restoration in the Blue Mountians of northeast Oregon

Creator:: Ebersole, Joseph Lamar
Abstract:: The restoration of rivers and streams should be based on a strong conceptual framework. Streams are developing systems. As such, streams exhibit temporal behaviors that change with changing stream environments. Underlying the dynamic development of streams is potential capacity. Streams express this capacity as an array of habitats over time...

Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Watershed-scale vegetation patterns in a late-successional forest landscape in the Oregon Coast Range

Creator:: Wimberly, Michael C.
Abstract:: Knowledge about vegetation patterns and ecological processes in unmanaged, late-successional watersheds is needed to provide a foundation for forest management strategies aimed at conserving native biodiversity. I examined influences of environmental variability and disturbance history on forest structure and composition in the Cummins Creek Wilderness, located on the central Oregon...

Summertime water temperature trends in Steamboat Creek Basin, Umpqua National Forest

Creator:: Holaday, Steven A.
Abstract:: The Steamboat Creek basin drains 227 mi² (588 km²) of steep forested terrain into the North Umpqua River of Southwest Oregon, 39 mi (63 km) northeast of Roseburg. Summer base flows for Steamboat Creek average 83 cfs (2.35 m³/sec). Steamboat Creek and its tributaries are considered important to the production...

Oregon spotted frog (Rana pretiosa) habitat use and herbage (or biomass) removal from grazing at Jack Creek, Klamath County, Oregon

Creator:: Shovlain, Amie M.
Abstract:: We evaluated the effects of herbage removal from livestock grazing on Oregon spotted frog (Rana pretiosa) habitat use by monitoring frog locations in grazed and matched ungrazed treatments across a range of grazing intensities at Jack Creek, Fremont-Winema National Forest, Oregon. Thirteen cattle exclosures were deployed along Jack Creek in...

Processes that influence the downstream propagation of heat in streams below clearcut harvest units : Hinkle Creek paired watershed study

Creator:: Otis, Timothy Leonard
Abstract:: This research investigates the direct and downstream impacts of clearcut harvest units on stream temperature as a part of the Hinkle Creek Paired Watershed Study. The Hinkle Creek watershed is located in the foothills of the Cascade Mountains about 30 kilometers northeast of Roseburg, Oregon, is privately owned, and supports...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

The ecology of riparian ecosystems of Northeast Oregon : shrub recovery at Meadow Creek and the structure and biomass of headwater Upper Grande Ronde ecosystems

Creator:: Case, Richard L.
Abstract:: Riparian ecosystems play numerous and essential roles related to the quality and flow of water, and food/habitat for fish, and varieties of wildlife. Due to lateral and linear linkages throughout the landscape, these zones influence the integrity of the terrestrial as well as the entire aquatic-riverine ecosystem. Since Euro-American settlement...

Biologic activity in two western Oregon Douglas-fir stands : a research link to management

Creator:: Hope, Sharon Margaret
Abstract:: Information about forest substrate respiration, nitrogenase activity and mineralizable nitrogen may be incorporated into carbon and nitrogen budgets that comprise an important element of forest management planning. In this study, substrate respiration, nitrogenase activity and mineralizable nitrogen were measured in two western Oregon Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stands within...

Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...
