    A River Imaginary: Nature and Narrative in the Columbia River Gorge.

    Full text link
    The Columbia River, one of the most dominant geographic features of the Pacific Northwest, drains nearly 259,000 square miles of territory as it traverses local, state, and national boundaries. From its headwaters in Canada to its mouth at the Pacific Ocean, the Columbia is vitally important to those who live near it, work on it, or depend upon the hydroelectric power that comes from it. This dissertation examines the development of the Columbia through the lens of cultural history. By identifying and tracking the divergent human meanings given to the river—a corpus of ideas that I refer to as the Columbia’s river imaginary—this study reveals how popular understandings of the river ebbed and flowed with the water itself, morphing and changing as the landscape of the river was transformed by hydroelectric dams, irrigation projects, navigation improvements, and the politics of salmon conservation. To describe these physical and cultural changes this dissertation focuses narrowly on one particular section of the river, the Columbia River Gorge, and it engages a wide array of cultural texts that describe the landscape—sources that include contemporaneous articles from local and national newspapers, federal and state government documents, tourist brochures, oral histories, environmentalist literature, folk music, photographs, landscape paintings, and documentary film. These sources reveal broad patterns in how people imagined the Columbia River’s history, its proper uses, and its relationship to the communities nearby. By tracing the patterns that emerge, this dissertation illuminates how the ‘cultural’ river and the ‘natural’ river interacted dialogically—explaining how the Columbia’s river imaginary shaped (and was shaped by) both the material ecology of the river and the political economy of the nation. This approach to the history of the Columbia reveals a dynamic but uneven process of continual reinvention, where culture and nature collide, abut, and overlap to shape the history of the river. In this analysis, cultural narratives appear not only as tools wielded, but also as the terrain upon which political, economic, and ecological contests were waged and won.Ph.D.American CultureUniversity of Michigan, Horace H.

    Practical Guide to Measuring Wetland Carbon Pools and Fluxes

    Get PDF
    Wetlands cover a small portion of the world, but have disproportionate infuence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fuxes. However, the underlying biogeochemical processes that afect wetland C pools and fuxes are complex and dynamic, making measurements of wetland C challenging. Over decades of research, many observational, experimental, and analytical approaches have been developed to understand and quantify pools and fuxes of wetland C. Sampling approaches range in their representation of wetland C from short to long timeframes and local to landscape spatial scales. This review summarizes common and cutting-edge methodological approaches for quantifying wetland C pools and fuxes. We frst defne each of the major C pools and fuxes and provide rationale for their importance to wetland C dynamics. For each approach, we clarify what component of wetland C is measured and its spatial and temporal representativeness and constraints. We describe practical considerations for each approach, such as where and when an approach is typically used, who can conduct the measurements (expertise, training requirements), and how approaches are conducted, including considerations on equipment complexity and costs. Finally, we review key covariates and ancillary measurements that enhance the interpretation of fndings and facilitate model development. The protocols that we describe to measure soil, water, vegetation, and gases are also relevant for related disciplines such as ecology. Improved quality and consistency of data collection and reporting across studies will help reduce global uncertainties and develop management strategies to use wetlands as nature-based climate solutions

    The State of Coral Reef Ecosystems of the United States and Pacific Freely Associated States: 2005

    Get PDF
    Executive Summary: For over three decades, scientists have been documenting the decline of coral reef ecosystems, amid increasing recognition of their value in supporting high biological diversity and their many benefits to human society. Coral reef ecosystems are recognized for their benefits on many levels, such as supporting economies by nurturing fisheries and providing for recreational and tourism opportunities, providing substances useful for medical purposes, performing essential ecosystem services that protect against coastal erosion, and provid-ing a diversity of other, more intangible contributions to many cultures. In the past decade, the increased awareness regarding coral reefs has prompted action by governmental and non-governmental organizations, including increased funding from the U.S. Congress for conservation of these important ecosystems and creation of the U.S. Coral Reef Task Force (USCRTF) to coordinate activities and implement conservation measures [Presidential Executive Order 13089]. Numerous partnerships forged among Federal agencies and state, local, non-governmental, academic and private partners support activities that range from basic science to systematic monitoring of ecosystem com-ponents and are conducted by government agencies, non-governmental organizations, universities, and the private sector. This report shares the results of many of these efforts in the framework of a broad assessment of the condition of coral reef ecosystems across 14 U.S. jurisdictions and Pacific Freely Associated States. This report relies heavily on quantitative, spatially-explicit data that has been collected in the recent past and comparisons with historical data, where possible. The success of this effort can be attributed to the dedication of over 160 report contributors who comprised the expert writing teams for each jurisdiction. The content of the report chapters are the result of their considerable collaborative efforts. The writing teams, which were organized by jurisdiction and comprised of experts from numerous research and management institutions, were provided a basic chapter outline and a length limit, but the content of each chapter was left entirely to their discretion. Each jurisdictional chapter in the report is structured to: 1) describe how each of the primary threats identified in the National Coral Reef Action Strategy (NCRAS) has manifested in the jurisdiction; 2) introduce ongoing monitoring and assessment activities relative to three major categories of inquiry – water quality, benthic habitats, and associated biological communities – and provide summary results in a data-rich format; and 3) highlight recent management activities that promote conservation of coral reef ecosystems
