DOWNLOAD EBOOKThe National Marine Conservation Areas System Plan is an important step in the process of creating a finite network of national marine conservation areas. The plan sets out an approach for the system's design in which Canada's three bordering oceans and the Great Lakes have been divided into 29 distinct marine regions, with a long-term goal of having a national marine conservation area within each region. The plan also attempts to portray each marine region with descriptions of its wildlife, marine and coastal environments, and current status of conservation areas in the region. The appendix includes a glossary and a list of marine-associated species assigned a status by the Committee on the Status of Endangered Wildlife in Canada.

DOWNLOAD EBOOKThis 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

DOWNLOAD EBOOK"[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.

DOWNLOAD EBOOK"Snails and slugs have a reputation as slimy, repulsive creatures that are nothing more than garden pests, but they are important components of the ecosystems they live in. In fact, most of the pest slugs and snails are introduced species that have come here with the plants we import for our gardens. Worldwide there are more species of snails and slugs than all the mammals, birds, reptiles and amphibians combined, yet they are often overlooked because of their relatively small size. Land snails and slugs are well adapted to live in almost any kind of environment, from high arctic tundra to tropical forests. In British Columbia, they can be found just about everywhere. Land Snails of British Columbia describes all 92 species of terrestrial molluscs in our province. It includes photographs and detailed drawings of each, diagnostic keys and a selection of colour photographs to aid in identification. With each species description, the author discusses its natural history and distribution in the province. He also talks about reproduction, life history, diet, locomotion and shell structure (even slugs have shells). Nature buffs and anyone interested in looking past the bad reputation of these much-maligned creatures will find this handbook an enlightening guide. For gardeners, this book will tell you which snails to cast out of your garden and which ones to keep, because some snails and slugs are beneficial to gardens and some even prey on their pestilent relatives."--
