Few animals in the world are as famous or as infamous as the beaver, and none save our species has the ability to so dramatically transform its environment. Beavers are remarkable animals. They have teeth that self-sharpen and never stop growing, and a heart that slows down and valves that close in their ears and noses when they dive. Their tail is the most multi-purpose of any animal on this planet; in addition to communication its many functions include serving as an air conditioner in summer and a food pantry in winter. From mighty moose that glean sodium from aquatic plants to swallows that live in drowned trees and tiny butterflies that nectar in meadows where a pond once stood, myriad organisms benefit from the actions of beavers. This book is a comprehensive overview of the lives of beavers and the habitats that arise from their actions. It is a visual extravaganza: approximately 400 photographs provide intimate insights into the lives of beavers and the inhabitants of their ponds and related habitats. Many new observations and rarely seen moments - such as beavers fighting - are documented in it.
