Sea otters once ruled the Pacific Ocean, but the fur trade of the eighteenth and nineteenth centuries brought this predator to near extinction. Today they’re slowly coming back from the brink, and scientists are learning more about their pivotal role as one of nature’s keystone species. This book looks at the history, biology, behavior and uncertain future of sea otters. Author and photojournalist Isabelle Groc takes us into the field: watching sea otter rafts off the British Columbia coast from a kayak, exploring what makes their fur coats so special, understanding how their voracious appetites are helping kelp forests thrive and, ultimately, learning how sea otters are leaving their mark (or paws) on every part of the ecosystem. They might be one of the most adorable creatures in the ocean, but kids will discover how their survival is key to a rich, complex and connected ecosystem.

Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. Covers scientific, cultural, economic and political components of sea otter conservation Provides guidance on how to manage threats to the sea otter populations in the face of future global changes Highlights the effects that interactions of coastal animals have with the marine ecosystem

"Captivating. . . . a full portrait of this adorable and ecologically important animal." —Publishers Weekly A science journalist travels the Pacific Coast in search of sea otters in this entertaining and inspiring book on the importance and history of this charismatic endangered species Sea otters—the adorable, furry marine mammals often seen floating on their backs holding hands—reveal the health of the coastal ecosystem along the Pacific Ocean. Once hunted for their prized fur in the 18th and 19th centuries, these animals nearly went extinct. Only now, nearly a century after hunting ceased, are populations showing stable growth in some places. Sea otters are a keystone species in coastal areas, feeding on sea urchins, clams, crab, and other crustaceans. When they are present, kelp beds are thick and healthy, providing homes for an array of sea life. When otters disappear, sea urchins take over, and the kelp disappears along with all the creatures that live in the beds. Now, thanks to their protected status, sea otters are making a comeback in California, Washington, and Alaska. In this hopeful book, science writer Todd McLeish embarks on an epic journey along the Pacific Coast—traveling from California to Alaska—to track the status, health, habits, personality, and viability of sea otters, and reveals how conservationists brought them back from the brink of extinction.

The impetus for this volume comes from two sources. The first is scientific: by virtue of a preference for certain large benthic invertebrates as food, sea otters have interesting and significant effects on the structure and dynamics of nearshore communities in the North Pacific. The second is political: be cause of the precarious status of the sea otter population in coastal California, the U.S. Fish and Wildlife Service (USFWS) announced, in June 1984, a proposal to establish a new population of sea otters at San Nicolas Island, off southern California. The proposal is based on the premise that risks of catastrophic losses of sea otters, due to large oil spills, are greatly reduced by distributing the population among two geographically separate locations. The federal laws of the U.S. require that USFWS publish an Environmental Impact Statement (ElS) regarding the proposed translocation of sea otters to San Nicolas Island. The EIS is intended to be an assessment of likely bio logical, social, and economic effects of the proposal. In final form, the EIS has an important role in the decision of federal management authority (in this case, the Secretary of the Interior of the U.S.) to accept or reject the proposal.

“The bones recovered from the middens of the northeastern Pacific shorelines have important stories to tell biologists, marine mammalogists, and those concerned with marine conservation. This volume unearths a wealth of information about the historical ecology of seals, sea lions, and sea otters in the North Pacific that spans thousands of years. It provides fascinating insights into how the world once looked, and how it may one day look again as seals, sea lions, and sea otters reclaim and recolonize their former haunts.”—Andrew Trites, Director, Marine Mammal Research Unit, University of British Columbia “Braje and Rick have assembled a compelling set of case studies on the long-term and complex interactions between people, marine mammals, and environments in the Northeast Pacific. The promise of zooarchaeology as historical science is on full display, as researchers use geochemistry, aDNA, morphometrics, and traditional analytic methods to address questions of utmost importance to the long-term health of coastal ecosystems. If this book doesn't convince conservation biology about the need to take the long view of animal histories and ecosystems into account in developing conservation management plans, I'm not sure what will.”—Virginia L. Butler, Department of Anthropology, Portland State University

2019 Choice Outstanding Academic Title More than any other nonhuman species, it was the sea otter that defined the world’s largest oceanscape prior to the California gold rush. In addition to the more conventional aspects of the sea otter trade, including Russian expansion in Alaska, British and American trading in the Pacific Northwest, and Spanish colonial ventures along the California coast, the global importance of the species can be seen in its impact on the East Asian maritime fur trade. This trade linked Imperial China, Japan, and indigenous Ainu peoples of the Kurile Islands as early as the fifteenth century. In Sea Otters: A History Richard Ravalli synthesizes anew the sea otter’s complex history of interaction with humans by drawing on new histories of the species that consider international and global factors beyond the fur trade, including sea mammal conservation, Cold War nuclear testing, and environmental tourism. Examining sea otters in a Pacific World context, Ravalli weaves together the story of imperial ambition, greed, and an iconic sea mammal that left a determinative imprint on the modern world.
