A Spatial Assessment of Conservation Opportunities in the Willamette River Floodplain between Corvallis and Albany, Oregon

Creator:: Baker, Jeffrey M.
Abstract:: The Willamette River floodplain has been highly modified by urbanization, conversion of land to agriculture, construction of dams and revetments, and regulation of flow, all of which have reduced floodplain processes that provide valuable ecosystem services such as fish and wildlife habitat and flood storage. Efforts to protect and restore...

Rivers and Roads : Exploring How Environmental Governance Impacts State Management of Forest Roads

Creator:: Detwiler, Stacey M.
Abstract:: This study explores how environmental governance mechanisms affect state management of forest roads to address the chronic delivery of sediment to streams in Oregon, Washington, and California on private and state forestlands. Forest roads can degrade water quality and harm aquatic life when runoff mobilizes fine sediments from the road...

Investing upstream : a social-ecological systems perspective on water utility investments in ecosystem services

Creator:: Bennett, Drew E.
Abstract:: The concept of ecosystem services broadens perspectives on nature to include not only intrinsic value but also the utilitarian value it provides to society. Viewing nature through this lens informs our understanding of how particular ecological processes benefit different actors. In this research, I examine how water utilities in the...

Reconciling Working Landscapes on State and Federal Lands with Endangered Species Act Requirements: Emerging Governance Surrounding Beaver-Related Watershed Restoration in Oregon

Creator:: Pike-Urlacher, Zach R.
Abstract:: Reconciling working landscapes with Endangered Species Act (ESA) requirements is a vexing challenge playing out in watersheds across the western United States. Beaver-related watershed restoration (BRR) methodologies have the potential to reconcile competing demands for resource extraction and recovery of ESA-listed species by restoring ecosystem functionality more effectively and at...

Ready for Anything: Adaptive Capacity in Western States' Water Plans

Creator:: Cogan, Leah R.
Abstract:: In the western United States, climate change is likely to bring greater uncertainty and extreme events outside the range for which water infrastructure, governance, and allocation mechanisms have been designed. In addition, many water systems already struggle with issues of institutional fragmentation, ineffective governance, and unsustainable management practices. Adaptive capacity,...

Reallocating resources, rebuilding community : the Klamath Basin agreements and the emergence of adaptive governance

Creator:: Chaffin, Brian C.
Abstract:: The concept of "adaptive governance" represents a spectrum of hybrid approaches to environmental governance employed to guide management of complex social-ecological systems under conditions of high uncertainty. While the concept of adaptive governance has benefited from over a decade of theoretical development, empirical examples of transitions towards adaptive governance are...

Beyond random acts of conservation : an institutional analysis of the Natural Resource Conservation Service's Agricultural Water Enhancement Program

Creator:: Burright, Harmony S. J.
Abstract:: Irrigated agriculture accounts for 90 percent of consumptive use of freshwater in the western US and is considered the largest contributor to nonpoint source water pollution. The diffuse nature of most water quality and quantity challenges necessitates institutions that can more effectively engage agricultural producers in strategic, integrated, watershed-scale approaches...
