As a prominent and ecologically important species, the North American beaver (Castor canadensis) plays a crucial role in Idaho by maintaining and shaping aquatic habitats. With their stocky bodies, brown coat, flat tail, and long, yellow teeth, the beaver is easily recognizable. As an herbivore, their diet mainly consists of roots, aquatic plants and woody plants. Beavers are the largest rodents in North America and are ecosystem engineers. The presence of beaver shapes habitat in ways that support great biodiversity. They provide habitat and resources to other species by building dams that form slow-moving ponds and reduce erosion.
