Objective:
The overall goal of this research project was to understand the socioeconomic interactions that influence biophysical functions and priorities for habitat restoration and protection. The project evaluated how policy and management of land and water uses influence river ecosystems, riparian and stream habitats, fish populations, and human systems of the lower Cedar River Basin near Seattle, WA. The specific objectives of this research project were to: (1) understand how retrospective and contemporary societal, policy, and environmental forces influence the current environment; (2) develop the ability to assess and anticipate biophysical and human system responses; and (3) formulate and examine the effectiveness of policies for restoring damaged river and floodplain ecosystems.
Summary/Accomplishments (Outputs/Outcomes):
This final report summarizes interdisciplinary research that evaluated the influences of societal and biophysical factors on public perspectives and habitat management activities related to restoration, watershed ecology, hydrology, and human uses. This research project was funded by the U.S. Environmental Protection Agency's (EPA) Science To Achieve Results program, and involved several interacting societal and watershed components and their investigation by two disciplines: societal factors (School of Marine Affairs) and biophysical factors (School of Aquatic and Fishery Sciences). This final report summary includes overviews of research integration, activities, and findings of linked studies of societal and biophysical forces acting within the lower Cedar River drainage near Seattle. We discuss how we assessed recent changes in land uses, hydrology, and fish habitats within the Cedar River drainage and the realities of improving river ecosystems, given policy and management requirements and public opinion.
The study area, the lower Cedar River drainage, has been greatly modified by human activities. Highly altered channels, floodplains, and tributary watersheds occur along approximately 34 km of the lowland reaches of the river channel. Our research indicates that historical forest harvest and settlement patterns along with recent urban expansion—in terms of land conversions, flow regulation, flood control, and transportation facilities—have caused increases in peak flow events, changes in fish and wildlife communities, and extensive losses of aquatic and riparian habitats.
Our research approach included integrated biophysical and societal analyses that assess changes in land uses, hydrology, and fish habitats and the reality of meeting management requirements for habitat and salmon recovery. Models were developed that facilitate the evaluation of how biophysical and societal factors interact under different degrees of urbanization within watersheds of the Cedar River drainage. A series of quantitative-spatial models incorporate different land cover, physiographic, hydrology, and ecological processes and social factors that are relevant to policy and management actions. Four inter-related societal analyses identify institutional and public actions and perceptions that influence the protection and restoration of salmon and their habitats.
A conceptual model of the "system" under study guided research coordination. The model defined a level of generality sufficient to encompass both biophysical and human elements (e.g., social values, policy, and management activities) that reflect real-world situations. This model facilitated formal and informal integration activities across the societal and biophysical domains of the project. The integration that emerged became a significant determinant of this research project's overall scope and direction. Our most effective approaches evolved over the course of the research project in ways not anticipated when the proposal was submitted. We found that formal and informal coordination processes were both important, and that loosely defined linkages were as valuable as more formalized tight couplings. In closing, our emphasis on exploring research questions in spatially explicit ways has greatly facilitated the integration and evolution of our research. We believe that our modeling and integration efforts provide products that will improve decisionmaking and environmental planning processes. For example, we have contributed to the literature on restoration discourse, watershed hydrology, and fish uses of restored habitats; developed criteria for cumulative impacts assessment; analyzed the institutions acting to preserve salmon and their habitats; and generated a wealth of information on public perceptions toward protection and restoration management activities within the Cedar River drainage.
