Even on a hot day in a dry summer, beaver ponds remain a wet and bustling oasis for wildlife. Mass Audubon has many beaver ponds within its sanctuary network, and we may have another one soon. We anticipate adding roughly 86 acres to Rutland Brook Wildlife Sanctuary in central Massachusetts within the next year or so. This pristine patch of woodland has many desirable natural features. However, the beaver pond on it may be the most valuable.
Beavers build dams to flood sections of forest using mud, sticks and small trees. This creates a watery safe zone from predators and habitat for the aquatic plants that make up a large part of their diet. In the process, they also build habitat for a variety of other species.
On my visit to this beaver pond last week, the air filled with the chatter of tree swallows, quacking of ducks and the buzzing of dragonflies. Along the banks I found numerous trees gnawed at their base—a sign of a healthy and industrious beaver colony. I couldn’t help but admire their handiwork.
