Book Description
"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."--

Book Description
This is the first volume in a 4-volume set, which is the culmination of two decades of research and writing. For the first time, the natural history, migration patterns, habitat requirements, reproductive biology, and distribution of the province's birdlife are combined in one publication. This is a reprint of the original volume published in 1990 by the Royal British Columbia Museum and the Canadian Wildlife Service. No changes or updates in content have been made from the original edition.

Book Description
The Salton Sea, California’s largest inland lake, supports a spectacular bird population that is among the most concentrated and most diverse in the world. Sadly, this crucial stopover along the Pacific Flyway for migratory and wintering shorebirds, landbirds, and waterfowl is dangerously close to collapse from several environmental threats. This book is the first thoroughly detailed book to describe the birds of Salton Sea, more than 450 species and subspecies in all. A major contribution to our knowledge about the birds of western North America, it will also be an important tool in the struggle to save this highly endangered area. Synthesizing data from many sources, including observations from their long-term work in the area, the authors’ species accounts discuss each bird’s abundance, seasonal status, movement patterns, biogeographic affinities, habitat associations, and more. This valuable reference also includes general information on the region’s fascinating history and biogeography, making it an unparalleled resource for the birding community, for wildlife managers, and for conservation biologists concerned with one of the most threatened ecosystems in western North America.

Book Description
"This volume provides a blueprint for managing the challenges of ocean conservation using marine historical ecology--an area of study evolving as societies confront ocean ecosystems that are being drastically altered by human activity. Applying the practice of historical ecology developed in terrestrial environments, Marine Historical Ecology guides the creation of historical baselines for marine species and ecosystems in order to inform and improve conservation and management efforts"--Provided by publisher.

Book Description
The Rockies are familiar to everyone in North America, yet few appreciate the true diversity of these mountains. This book covers the Rockies from sagebrush flats to icy tundra, and explores the range’s geological formation; its role in shaping the West; the plants and animals that form its many ecosystems; and the complex relationship between humans and the Rockies. Written in a lively, engaging style, the book features spectacular color photographs, elegant line drawings, and interesting sidebars.
