The Busy Beaver by Nicholas Oldland

From chapters.ca:
The busy but careless beaver spends his days following random impulses, rarely thinking things through and leaving in his wake a devastated forest filled with stumps, half- nibbled trees and injured, homeless animals. But then one day the beaver finds himself on the wrong side of a falling tree, which as it turns out, is just the thing to knock some sense into him. After reflecting on his behaviour, he decides to make some changes. Soon, the now wiser and gentler beaver is getting down to the business of making things right, much to the delighted surprise of his forest friends. This charming story from the creator of Big Bear Hug and Making the Moose Out of Life gently teaches youngsters how to take care with others, as well as the world around us.
