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 commuï¿½nication 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 swalï¿½lows 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: ap-proximately 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.

This weighty record showing 30 years of beaver watching is definitely worth the wait.Everything about this book is impressive: its stunning photographs, gripping account of little known beaver details, and its truly classy lay out, right down to the beaver silhouetted page number in the corner. I had prepared myself to be impressed, and was not disappointed.Michael Runtz's book was still filled with gloriously unexpected treasures. From the amazing photograph of a beaver floating on its back (yes you read that right, not a sea otter, I swear, he speculates he might be picking a splinter from its teeth with its rear toe) to the exciting collection of facts about their lives, (did you know that when beavers breathe they replaces a whopping 75% of the oxygen in their lungs? Compared to the paltry human rate of 15%!) or that beaver tails in colder climates actually look different in the fall than the spring, depending on how much fat content they’ve lost from it over the winter?If some of the photos seem vaguely familiar they should, Runtz supplied his stills to Jari Osborne’s Beaver Documentary (Beaver Whisperer in Canada, and Nature’s “Leave it to Beaver” in America). My favorite chapters were those documenting beaver effects. First a lovely one showing the biodiversity that blooms in beaver ponds, with beautiful macro photography of gnats, insects, dragonflies, to featherlight photos of birds and water fowl, to richly-textured images of otter and moose you can practically feel. Then a beautifully solemn one about what happens to the trees beavers kill by flooding. (Showing excellent homes for a variety of woodpeckers, wood duck and blue heron).
