The Elwha River Restoration: Landscape Change, Salmon, And Sense Of Place, Kelseyanne Johnson
The Elwha River Restoration: Landscape Change, Salmon, And Sense Of Place, Kelseyanne Johnson
All Master's Theses
Removal of the Elwha River dams to restore the ecosystem and salmon fisheries is the largest project of its kind in the history of the United States. Spanning decades and affecting generations, this project has changed and will continue to change the landscape. This research examined the influence of the anticipated return of salmon on 18 key stakeholders' sense of place of the Elwha River. For almost all stakeholders, changes to the Elwha landscape are welcomed as they expect that salmon will restore the ecosystem to its natural state. Narrative data revealed dominant themes in participants' sense of place expressed …
Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
All Master's Theses
Beaver reintroduction programs are increasingly being viewed as a way to enhance salmonid habitat and production. However, the actual effectiveness of using beavers as a habitat enhancement tool for ESA listed steelhead Oncorhynchus mykiss populations is unknown. We examined the type of habitat, at both the microhabitat and mesohabitat levels, preferred by steelhead in three small streams in the upper Yakima Basin, WA through standard snorkel surveys and habitat measurements. Our results suggest that steelhead in small streams strongly prefer (relative to availability) microhabitats that have deeper water(> 30 cm), slow stream velocities(< 0 .05 mis), and complex cover types. Habitat partitioning among the size-classes (small< 50 mm, medium 50-90 mm, large> 90 mm total length, TL) principally operated …
Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman
Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman
All Master's Theses
The importance of cultural resource preservation cannot be overstated; however local economies are at least as important. Due to conservative archaeological site protection practices in Region 5 of the United States Forest Service, the economy of Northeastern California is being adversely affected. In an attempt to help the Forest Service make more informed management decisions and improve the Northeastern California economy, I undertook experiments on the effects of timber harvesting on lithic scatters on Modoc National Forest. The experiments involved placement of 225 glass tiles (proxy lithics) in each of three plots subject to vehicle traffic and log dragging by …
