Nature's Busy Architects
Beavers are remarkable animals that change their environments more than almost any other creature on Earth. When beavers move into a creek or stream, they use their sharp orange teeth to chew down tree trunks and branches. Next, they haul mud, stones, and sticks into the flowing water to build a strong dam.
This beaver dam blocks the rushing water and creates a deep, calm pond. The new pond provides a safe home where beavers can construct a cozy dome-shaped lodge with underwater doors. Even better, this wetland gives fish, frogs, ducks, and water bugs a healthy place to live and find food. Through their hard work, beavers transform simple streams into lively habitats for hundreds of plants and animals.
