  Citation × Citation Citation Abstract Copy Title: Administrative Design for Yakima-Klickitat Production Project: Final Report Author: Churchill, Jack, Shissler, Lee, Edner, Sheldon, Smith, Randy Year: 1990 This report provides the administrative design to implement the Yakima/Klickitat Production Project. This project is a scientifically designed salmon fishery restoration project funded by the Bonneville Power Administration in compliance with the .fishery policies established by the Northwest Power Planning Council under the authority of the Northwest Power Planning Act. This project breaks new ground in the field of fishery management. It is the first full scale application of supplementation technology directed toward maintaining and rebuilding native fish stocks and sub stocks with hatchery rearing methods. The work of the organization is an inherently more complex production function than traditional fish hatchery operations. This is in part because the project requires a high level of continuing quality control. It is also due in part because the fisheries management takes place over an extended geographical space of the watershed. The pre-design work for this project has been underway since 1987 by an ad hoc planning group composed of representative of the Yakima Indian Nation, the Washington Department of Fisheries and the Washington Department of Wildlife, and private consultants under funding of the Bonneville Power Administration. The project experimental design has been developed by the Experimental Design Work Group. The Bonneville Power Administration is contracting for design and construction of the fish rearing facilities. The research challenge was to design an organization to .implement the adaptive management concept of biological systems management. The management of complex biological systems such as salmon fish runs is character:ized by a high degree of uncertainty. Management for uncertain outcomes requires an organizational process that will induce a continuing learning atmosphere. Over time, most bureaucratic organizations suffer from inertia and are not conducive to a learning environment. Research methods involved the review of literature and related administrative experience, an interview process, a modified Delphi questionnaire, a series of group dynamic exercises, and observation of the work teams during the last six months of the planing process. The results of our research suggest that a new non-profit corporation be formed to implement the program under the direction of the three primary fish management basin agencies. The corporation should have flexibility and the organization will be phased in during the five year planning and construction cycle. A primary result of our research is the conclusion that the team management concept be the dominant organizational unit for both management of field operations and for management of scientific design and evaluation.

• 32. [Article] Study of Prestige and Resource Control Using Fish Remains from Cathlapotle, a Plankhouse Village on the Lower Columbia River

  Citation × Citation Citation Abstract Copy Title: Study of Prestige and Resource Control Using Fish Remains from Cathlapotle, a Plankhouse Village on the Lower Columbia River Author: Rosenberg, J. Shoshana Year: 2015 Social inequality is a trademark of Northwest Coast native societies, and the relationship between social prestige and resource control, particularly resource ownership, is an important research issue on the Northwest Coast. Faunal remains are one potential but as yet underutilized path for examining this relationship. My thesis work takes on this approach through the analysis of fish remains from the Cathlapotle archaeological site (45CL1). Cathlapotle is a large Chinookan village site located on the Lower Columbia River that was extensively excavated in the 1990s. Previous work has established prestige distinctions between houses and house compartments, making it possible to examine the relationship between prestige and the spatial distribution of fish remains. In this study, I examine whether having high prestige afforded its bearers greater access to preferred fish, utilizing comparisons of fish remains at two different levels of social organization, between and within households, to determine which social mechanisms could account for potential differences in access to fish resources. Differential access to these resources within the village could have occurred through household-level ownership of harvesting sites or control over the post-harvesting distribution of food by certain individuals. Previous work in this region on the relationship between faunal remains and prestige has relied heavily on ethnohistoric sources to determine the relative value of taxa. These sources do not provide adequate data to make detailed comparisons between all of the taxa encountered at archaeological sites, so in this study I utilize optimal foraging theory as an alternative means of determining which fish taxa were preferred. Optimal foraging theory provides a universal, quantitative analytical rule for ranking fish that I was able to apply to all of the taxa encountered at Cathlapotle. Given these rankings, which are based primarily on size, I examine the degree to which relative prestige designations of two households (Houses 1 and 4) and compartments within one of those households (House 1) are reflected in the spatial distribution of fish remains. I also offer a new method for quantifying sturgeon that utilizes specimen weight to account for differential fragmentation rates while still allowing for sturgeon abundance to be compared to the abundances of other taxa that have been quantified by number of identified specimens (NISP). Based on remains recovered from 1/4" mesh screens, comparisons between compartments within House 1 indicate that the chief and possibly other elite members of House 1 likely had some control over the distribution of fish resources within their household, taking more of the preferred sturgeon and salmon, particularly more chinook salmon, for themselves. Comparisons between households provide little evidence to support household-based ownership of fishing sites. A greater abundance of chinook salmon in the higher prestige House 1 may indicate ownership of fishing platforms at major chinook fisheries such as Willamette Falls or Cascades Rapids, but other explanations for this difference between households are possible. Analyses of a limited number of bulk samples, which were included in the study in order to examine utilization of very small fishes, provided insufficient data to allow for meaningful intrasite comparisons. These data indicate that the inhabitants of Cathlapotle were exploiting a broad fish subsistence base that included large numbers of eulachon and stickleback in addition to the larger fishes. This study provides a promising approach for examining prestige on the Northwest Coast and expanding our understanding of the dynamics between social inequality and resource access and control.

Year: 2004 As part of a special issue of the 'Oregon Historical Quarterly,' discusses the native species of fish in the lower Columbia River described by Meriwether Lewis and William Clark in 1805-06. They identified red charr, salmon trout, sturgeon, anchovy, skeet, and other fish that Indians caught and used as trade items with the Corps of Discovery. However, editors of the Lewis and Clark journals have often erred in identifying the fish Lewis and Clark described; the challenge in identifying anadromous fish lies in changing coloration, markings, and examination of habitat. There has been a drastic decline of native fish since 1805 and a growing dominance of exotic species. Title: Where Have All the Native Fish Gone?

The authors reviewed ethnohistorical accounts and studies of archaeological sites to create a complex picture of Columbia River fisheries that challenges the prevailing view among anthropologists that salmon was the primary and predominant fishery among Chinookan peoples. The authors show that 19th century Native fishers targeted virtually all native fish species in the Lower Columbia River, and employed a wide range of strategies and tactics to acquire and process fish.

Year: 2017 Evidence of large earthquakes occurring along the Pacific Northwest Coast is reflected in coastal stratigraphy from Oregon to British Columbia, where there also exists an extensive archaeological record of Native American occupation. Tse-whit-zen, a large Native American village dating between ∼2800 yrs BP and the historic era, located on the Olympic Peninsula of Washington State, was excavated with exceptionally fine stratigraphic control allowing for precise comparison of these natural and cultural records. Here we report on the ∼10,000 fish remains from one 2 × 2 m excavation block; this assemblage spans the timing of one seismic event, allowing study of changes in relative taxonomic abundance through time that may coincide with earthquakes or other environmental changes. Results indicate a wide variety of fish taxa were used throughout the dated occupation. Comparisons of fish use before and after one earthquake event shows a decline in salmon (Oncorhynchus sp.) and an increase in herring (Clupea pallasii), shifts consistent with earthquake-related habitat loss. This serves as a pilot study for a large-scale collaborative project that is drawing on the range in animal types (invertebrates, mammals, birds, and fishes) to assess human response to gradual and abrupt environmental change at Tse-whit-zen.

The West End plan focused primarily on the area north of SW Salmon Street and the urban renewal area currently does not have a standing advisory committee to represent the Downtown neighborhood’s interests. This project consists of a neighborhood analysis to distill the identity of the area, an identification of the opportunities and challenges to development, and a strategy for DNA to be an active participant in the development of the South Park Blocks Area (SPBA). This project was conducted under the supervision of Deborah Howe, Barry Messer, and Ethan Seltzer.

  Citation × Citation Citation Abstract Copy Title: Sustainability from the Perspectives of Indigenous Leaders in the Bioregion Defined by the Pacific Salmon Runs of North America Author: Hall, David Edward Year: 2008 Extensive research suggests that the collective behavior of humanity is on an unsustainable path. As the evidence mounts and more people awaken to this reality, increased attention is being dedicated to the pursuit of answers for a just and sustainable future. This dissertation grew from the premise that effectively moving towards sustainability requires change at all levels of the dominant Western culture, including deeply held worldviews. The worldviews of many indigenous cultures offer alternative values and beliefs that can contribute to addressing the root causes of problems related to sustainability. In the bioregion defined by the Pacific Salmon runs of North America there is a rich heritage and modern day presence of diverse indigenous cultures. In-depth semi-structured interviews were conducted with 13 indigenous leaders from within this bioregion to explore their mental models of sustainability. These interviews followed a general structure that covered: (a) the personal background and community affiliation of each interviewee; (b) the meaning of the concept of sustainability from their perspective; (c) visions of a sustainable future for their communities; and, (d) how to achieve such a future. A content analysis of the interviews was conducted and summarized into a narrative organized to correspond with the general interview structure. A process oftestimonial validity established that most participants found the narrative to be an accurate representation of their perspectives. Participant feedback led to several phrasing changes and other identified issues are discussed, including one participant's critique of the narrative's use of a first-person plural voice. Major themes from the interviews include the role of the human being as caretaker actively participating in the web of life, the importance of simultaneously restoring culture and ecology due to their interdependence, the need to educate and build awareness, and the importance of cooperation. Understanding who we are as a living species, including our profound connection with nature, along with a holistic and intergenerational perspective are suggested as prerequisite for balancing and aligning human modes of being with the larger patterns of life. The closing discussion addresses the importance of social action and going beyond a conceptual understanding to an embodiment of sustainability.

This illustrates a highly diverse diet throughout occupation, though relative abundances of more offshore taxa decrease through time in favor of some nearshore taxa, possibly indicating the presence of a coseismic event. This thesis serves as part of a pilot study for a collaborative project that is underway. This larger project addresses human response to both gradual and abrupt environmental change through the analysis of all classes of Tse-whit-zen faunal remains, which provide a link to impacts on animal populations and in turn human subsistence.

  Citation × Citation Citation Abstract Copy Title: Impacts of Columbia River Discharge on Salmonid Habitat: 1. A Nonstationary Fluvial Tide Model Author: Jay, David A., Kukulka, Tobias Year: 2003 This is the first part of a two-part investigation that applies nonstationary time series analysis methods and the St. Venant equations to the problem of understanding juvenile salmonid access to favorable shallow-water habitat in a tidal river. Habitat access is a function of river stage, tidal range, and the distribution of bed elevation. Part 1 models nonstationary tidal properties: species amplitudes and phases and tidal range. Part 2 models low-frequency river stage in the Lower Columbia River and reconstructs historical water levels, using the tidal model from part 1. To incorporate the nonstationary frictional effects of variable river discharge into the tidal model, we decompose the tidal wave into tidal species and calculate daily tidal range. Our one-dimensional tidal model is based on analytic wave solutions to the linearized St. Venant equation and uses six coefficients per tidal species to represent the upstream evolution of the frictionally damped tidal wave. The form of the coefficients is derived from the St. Venant equations, but their values are determined objectively from the data. About 50 station-years of surface elevation data collected (1981-2000) below Bonneville Dam (235 km from the ocean) were processed with a wavelet filter bank to retrieve time series of tidal species properties. A min-max filter was used to estimate daily tidal range. Tidal range, diurnal, and semidiurnal amplitudes were predicted with mean root mean square errorsmm, which is significantly more accurate than predictions obtained from harmonic analysis. Thus despite the compact form of our solution, we model nonstationary fluvial tidal properties with a high level of accuracy. Title: Impacts of Columbia River Discharge on Salmonid Habitat: 1.
