Archaeological Evidence for Resilience of Pacific Northwest Salmon Populations and the Socioecological System over the last ~7,500 years Ecology and Society
Campbell, Sarah K.; Department of Anthropology, Western Washington University; Sarah.Campbell@wwu.edu; Butler, Virginia L.; Department of Anthropology, Portland State University; butlerv@pdx.edu.
Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the ecological–human system. Of several factors possibly...

Evolutionary History, Habitat Disturbance Regimes, and Anthropogenic Changes: What Do These Mean for Resilience of Pacific Salmon Populations? Ecology and Society
Waples, Robin S.; NOAA Fisheries Northwest Fisheries Science Center; robin.waples@noaa.gov; Beechie, Tim; NOAA Fisheries, Northwest Fisheries Science Center Environmental Conservation Division; Tim.Beechie@noaa.gov; Pess, George R.; NOAA Fisheries, Northwest Fisheries Science Center Environmental Conservation Division; George.Pess@noaa.gov.
Because resilience of a biological system is a product of its evolutionary history, the historical template that describes the relationships between species and their dynamic habitats is an important point of reference. Habitats used by Pacific salmon have been quite variable throughout their evolutionary history, and these habitats can be characterized by four key attributes of disturbance regimes: frequency, magnitude, duration, and predictability. Over the past two centuries, major anthropogenic changes to salmon ecosystems have dramatically altered disturbance regimes that the species experience. To the extent that these disturbance regimes assume characteristics outside the range of the historical template, resilience of salmon populations might be...

Reconnecting Social and Ecological Resilience in Salmon Ecosystems Ecology and Society
Bottom, Daniel L.; NOAA Fisheries, Northwest Fisheries Science Center; Dan.Bottom@noaa.gov; Jones, Kim K.; Oregon Department of Fish and Wildlife; kim.jones@oregonstate.edu; Simenstad, Charles A; University of Washington; simenstd@u.washington.edu; Smith, Courtland L; Department of Anthropology, Oregon State University; csmith@oregonstate.edu.
Fishery management programs designed to control Pacific salmon (Oncorhynchus spp.) for optimum production have failed to prevent widespread fish population decline and have caused greater uncertainty for salmon, their ecosystems, and the people who depend upon them. In this special feature introduction, we explore several key attributes of ecosystem resilience that have been overlooked by traditional salmon management approaches. The dynamics of salmon ecosystems involve social–ecological interactions across multiple scales that create difficult mismatches with the many jurisdictions that manage fisheries and other natural resources. Of particular importance to ecosystem resilience are large-scale shifts in oceanic and climatic regimes or in...

Resident perceptions of natural resources between cities and across scales in the Pacific Northwest Ecology and Society

As the global population becomes increasingly urban, research is needed to explore how local culture, land use, and policy will influence urban natural resource management. We used a broad-scale comparative approach and survey of residents within the Portland (Oregon)-Vancouver (Washington) metropolitan areas, USA, two states with similar geographical and ecological characteristics, but different approaches to land-use planning, to explore resident perceptions about natural resources at three scales of analysis: property level (“at or near my house”), neighborhood (“within a 20-minute walk from my house”), and metro level (“across the metro area”). At the metro-level scale, nonmetric...
