Riparian ecosystems provide critical habitat for a broad diversity of aquatic and terrestrial species. However, due to their connectivity along river corridors, and the tendency for people to build roads, infrastructure, and other settlements next to rivers, riparian ecosystems are vulnerable to colonization by invasive plant and animal species. Early...
In the Pacific Northwest, USA, the cumulative impact of human development has caused decades of salmon habitat degradation and the listing of multiple populations under the US Endangered Species Act. As a result, the need for implementation of recovery goals has encouraged the development of an economy focused on salmon...
Knowles Creek Research Review
This power point presentation was given to Northwest Fisheries Managers in November of 2013 during a conference at Oregon State University.
Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...
Aquatic ecological investigation is expanding to encompass considerations of
multiple scales across large landscapes. Much of the analysis included in this work
focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on
the Oregon coast. Coho salmon were chosen for an investigation of spatial scales,
network connections, and life...
This project explores the impact of land use decisions on dune processes at the
Oregon National Guard's Camp Rilea. located on the north coast of Oregon. It
used a combined analysis of historical and modern data sources to assess the
impact of land use practices. Historical sources including the journals...
Land management policies are ideas about nature projected onto the landscape. Culminations of social, economic, and scientific influences, these policies create standards affecting the function of ecological systems. In the case of riparian lands in the Oregon Coast Range, policy requirements vary considerably across federal, state, and private land ownerships....
This thesis explores the challenges of monitoring stream hydrology in a warmer and wetter climate in the Kenai Peninsula (KP) and Prince William Sound (PWS) region of Southcentral Alaska, located on the traditional territories of the Dena’ina, Ahtna, Alutiiq/Sugpiaq, and Eyak People. The physical and climatological extremes of this region...
Stream restoration efforts have increasingly started to focus on management actions that restore ecological function rather than focusing on species-specific habitat needs. Restoration practitioners in the Pacific Northwest have implemented numerous large-scale floodplain restoration projects to restore stream function at the valley scale. Some of these projects attempt to restore...
The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...
