The beaver dam, almost a kilometer long, is so impressive that it can even be seen on satellite images. The beavers in Canada’s Wood Buffalo National Park have been hard at work for decades, and their tree planting labor has paid off. Furry architects have created the world’s largest beaver dam.
The dam, which is about a kilometer long, is so massive that it even appears on satellite images. It remained hidden in the Alberta wilderness until 2007, when a researcher spotted the dam while looking at Google Earth. The beavers are currently building new dams nearby which, when connected to the main structure, can add over 100 meters to the total length. You can read about the largest man-made dams in the world in a separate selection.
Beavers are one of the few species capable of creating dams large enough to be seen from space. Toothy creatures are wonderful environmental engineers. Their dams redirect flows and even change entire ecosystems. These creations are designed to be extremely durable and are barriers that form pools and act as protective moats. Dams are able to protect beavers from predators such as wolves and bears.
It is likely that beavers began working on the dam in Alberta sometime in the 1970s, making it a multi-generational architectural project. A thick layer with earth, branches, stones and branches is covered with a layer of grass, which indicates a fairly long existence of the structure. The dam extends across a remote area of wetlands that provides the creatures with ample fresh water and an abundance of building materials. Due to the isolated location, it is difficult for a curious person to reach this place and disturb the beavers.
