Well, there are a few reasons for the title that you just read. First, beavers need somewhere to live that will protect them from predators and the elements. Their dams create deep pools of water that can act as a barrier between the beavers and land-based predators like coyotes and foxes. Second, building dams help beavers control the water level in an area. This is important because it allows them to create wetlands, which are perfect habitats for many other types of animals including fish, amphibians, reptiles, and birds. Lastly, by damming up a stream or river, beavers create a slow-moving body of water. This is ideal for their own needs because they can swim and float much more easily in these conditions. Additionally, the slower water makes it easier for them to gather food like plants and small animals.
So there you have it! Beavers build dams for shelter, to create wetlands, and to make swimming and gathering food easier. They are truly amazing creatures! Beavers were very important animals for the fur trappers and traders who lived at Fort Vancouver. Every year, fur trappers called voyageurs would travel far to find beaver.
How did the voyageurs know if a beaver was nearby? They could look for signs of a beaver, like chewed logs or branches, or footprints. But finding a beaver dam was a sure sign that a beaver was nearby! Read on to learn more about beavers and beaver dams, then experiment with making your own dam at home!
What is a beaver dam?
A beaver dam is a dam created by a beaver out of wood and mud. A dam is a structure that interrupts or slows the flow of water in a river or stream. Behind a dam, a lake or pond is formed.
Beavers make dams for a variety of reasons
Beavers construct dams across streams to create a pond in which they may reside in a “beaver lodge.” Predators like wolves, coyotes, and mountain lions are kept at bay by these ponds.
What materials do beavers use to construct their dams?
Beavers create dams by cutting trees and branches with their powerful incisor (front) teeth! Grass, pebbles, and mud are also used.
Do beavers live in a beaver dam?
Beavers construct dams to provide a secure pond in which to construct their beaver lodge. A beaver lodge is made of twigs, logs, pebbles, and mud with an underwater entrance (beavers are excellent swimmers!). Beavers have a safe spot to sleep, raise their young, remain warm in the winter, and hide from predators within their lodge.

Beaver dams do more than only provide a home for beavers! Beaver dams generate ponds that are essential homes for other wetland wildlife such as birds and fish. These ponds also aid in soil erosion control and flood reduction. Beavers are referred to as regarded be a “keystone species.” This implies they are crucial to an ecosystem because they alter or adapt their surroundings in a way that benefits others.
