This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This plan describes the coded-wire tagging of juvenile Chinook salmon Oncorhynchus tshawytscha on the Unuk River for the 2019 and 2020 brood years, which covers the coded-wire tagging of parr in fall of 2020 and 2021 and smolt in spring of 2021 and 2022, and sampling returning adults for age, sex, length, and coded-wire tags in escapement from the 2022 through 2027 return years. This study provides estimates of smolt and parr abundance, overwinter (freshwater) survival, mean lengths of juveniles, and harvest information of Chinook salmon originating from the Unuk River in Southeast Alaska. A separate project will be conducted on the Unuk River that employs aerial and foot survey peak counts to estimate large (≥660 mm mid eye to fork of tail length) adult Chinook salmon returning to the river in 2020 and 2021. The primary goals of this and the companion study are to estimate inriver run size, total run size, marine harvest-exploitation rate and harvest distribution, smolt and parr abundance, marine survival (smolt to adult) and overwinter survival (parr to smolt). The Alaska Department of Fish and Game uses this information to make local and regional management decisions, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Chinook Technical Committee.

Available in PDF, EPUB and Kindle. Book excerpt: Haa Leelk'w Has Aan' Saaxu / Our Grandparents' Names on the Land presents the results of a collaborative project with Native communities of Southeast Alaska to record indigenous geographic names. Documenting and analyzing more than 3,000 Tlingit, Haida, and other Native names on the land, it highlights their descriptive force and cultural significance. With community maps, tables, and photographs, this book will be invaluable for those seeking to understand Alaska Native geographic perspectives. As Tlingits from the Hoonah Indian Association explain in the book: "Long before Russian, French, Spanish, and British explorers mapped and named the mountains and bays of the Huna Tlingit homeland, we identified special places in our own vibrant, descriptive ways. Tlingit place names reflect important natural resources, ancestral stories, sacred places, and major geological and historic events. Our place names describe more than just inanimate locations for we perceive the mountains, glaciers, and streams to be as alive and aware as ourselves. Rather, they capture the history, emotions, and stories of our enduring relationship with a living, evolving landscape." "The new benchmark against which all future work will be measured." -Richard Dauenhauer, author of Russians in Tlingit America "Thomas Thornton and his Tlingit colleagues show how 'grandparents' names on the land' provide exquisite scaffolding for human ecologies in North America's far northwest--a moral universe inhabited by a community of beings in constant communication and exchange. This book will be a resource for the ages." -Julie Cruikshank, author of Do Glaciers Listen? Local Knowledge, Colonial Encounters, and Social Imagination "Restoring Tlingit placenames and their meanings will root our people back in place and decolonize the landscape, and Thornton has provided us with a fundamental tool to do exactly that. Sh t--oghaa xhat ditee--I am grateful." -Lance A. Twitchell, Xh'unei, University of Alaska Southeast Thomas F. Thornton is senior research fellow and director of the Environmental Change and Management Program at the Environmental Change Institute, School of Geography and the Environment, University of Oxford He is the author of Being and Place among the Tlingit.

Book Synopsis Salmon Without Rivers by : Jim Lichatowich
Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Available in PDF, EPUB and Kindle. Book excerpt: CLICK HERE to download the first chapter from A Long Treak Home * Compelling adventure with an environmental focus * An informative natural and cultural history of one of our last wild coastlines * Author is a pioneer in "packrafting," an emerging trend in backcountry travel In June 2007, Erin McKittrick and her husband, Hig, embarked on a 4,000-mile expedition from Seattle to the Aleutian Islands, traveling solely by human power. This is the story of their unprecedented trek along the northwestern edge of the Pacific Ocean-a year-long journey through some of the most rugged terrain in the world- and their encounters with rain, wind, blizzards, bears, and their own emotional and spiritual demons. Erin and Hig set out from Seattle with a desire to raise awareness of natural resource and conservation issues along their route: clear-cut logging of rainforests; declining wild salmon populations; extraction of mineral resources; and effects of global climate change. By taking each mile step by step, they were able to intimately explore the coastal regions of Washington, British Columbia, and Alaska, see the wilderness in its larger context, and provide a unique on-the-ground perspective. An entertaining and, at times, thrilling adventure, theirs is a journey of discovery and of insights about the tiny communities that dot this wild coast, as well as the individuals there whom they meet and inspire.
