Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status reports are working documents used in assigning the status of wildlife species suspected of being at risk. This document includes both an assessment and status report on the Enos Lake benthic and limnetic threespine stickleback species pair (Gasterosteus aculeatus) in Canada. It includes species information, distribution, habitat, and biology information, as well as population sizes and trends, limiting factors and threats, special significance of the species, and existing protection or other status.--Includes text from document.

This book describes the underlying water conditions and geologies that support viable riparia, illustrates the ecological characteristics of riparia, and discusses how riparia are used by human cultures as well as how riparia can be used to sustain environmental quality. In recent years riparian management has been widely implemented as a means of improving fisheries, water quality, and habitat for endangered species. This book provides the basic knowledge necessary to implement successful, long-term management and rehabilitation programs. - Treats riparian patterns & processes in a holistic perspective, from ecological components to societal activities - Contains over 130 illustrations and photos that summarize this complex ecological system - Synthesizes the information from more than 6,000 professional articles - Sidebars provide a look into ongoing research that is at the frontiers of riparian ecology and management

"[P]resents a science overview of the major forest management issues involved in the recovery of anadromous salmonids affected by timber harvest in the Pacific Northwest and Alaska. The synthesis reviews salmonid habitat requirements and potential effects of logging, describes the technical foundation of forest practices and restoration, analyzes current federal and non-federal forest practices, and recommends required elements of comprehensive watershed management for recovery of anadromous salmonids"--Note to readers (p. [ii]).

In 1962 the Green River was poisoned and its native fishes killed so that the new Flaming Gorge Reservoir could be stocked with non-native game fishes for sportsmen. This incident was representative of water management in the West, where dams and other projects have been built to serve human needs without consideration for the effects of water diversion or depletion on the ecosystem. Indeed, it took a Supreme Court decision in 1976 to save Devils Hole pupfish from habitat destruction at the hands of developers. Nearly a third of the native fish fauna of North America lives in the arid West; this book traces their decline toward extinction as a result of human interference and the threat to their genetic diversity posed by decreases in their populations. What can be done to slow or end this tragedy? As the most comprehensive treatment ever attempted on the subject, Battle Against Extinction shows how conservation efforts have been or can be used to reverse these trends. In covering fishes in arid lands west of the Mississippi Valley, the contributors provide a species-by-species appraisal of their status and potential for recovery, bringing together in one volume nearly all of the scattered literature on western fishes to produce a monumental work in conservation biology. They also ponder ethical considerations related to the issue, ask why conservation efforts have not proceeded at a proper pace, and suggest how native fish protection relates to other aspects of biodiversity planetwide. Their insights will allow scientific and public agencies to evaluate future management of these animal populations and will offer additional guidance for those active in water rights and conservation biology. First published in 1991, Battle Against Extinction is now back in print and available as an open-access e-book thanks to the Desert Fishes Council.

With sixty descriptive maps and accompanying text, The Biodiversity Atlas of British Columbia provides a broad overview of the province?s range of terrestrial and freshwater biological diversity. Bringing together data from numerous sources summarized in map form, the Atlas provides a window to B.C.?s diverse ecosystems, the species that live in them, and the elements of British Columbia?s biodiversity that make it globally significant. The Atlas also presents a visual perspective of a number of human-induced threats, including climate change, affecting biodiversity in B.C. today. The Atlas is designed to serve as a companion document to Taking Nature?s Pulse: The Status of Biodiversity in British Columbia ? a comprehensive scientific assessment of biodiversity in the province. Both the Atlas and Taking Nature?s Pulse are projects of Biodiversity BC, a partnership of conservation groups and government agencies.

The threat of deteriorating habitats and a loss of biodiversity make this reference work on the freshwater fishes of British Columbia more necessary than ever before. Eighty-one comprehensive species accounts aid accurate identification and consist of an illustration, the scientific and common names of the fish, its distinguishing characteristics, taxonomic comments, geographic distribution, a life-history summary, a habitat-use summary, and conservation comments. The book is a critical resource for biologists, naturalists, management and conservation officers, anglers, and members of the public who are concerned about our natural heritage. Foreword by Joseph S. Nelson.
