Thanks to The Chronicles of Narnia: The Lion, the Witch and the Wardrobe, beavers are pretty cool to kids everywhere. It is a nocturnal rodent, semi- aquatic and one of the hardest working animals. Known for building their homes from canals, and lodges, they are the second largest rodent in the world. The beaver plays an important role in the ecosystem, shaping its landscape and creating wetlands that other species benefit from. It creates dams to protect itself from its many predators such as; wolves, bears, and coyotes. These hard working rodents also create their own lodges, and utilize fresh mud during autumn season which freezes during the winter.
