River and Stream Ecosystems

Here are some animals that can be found in the river ecosystem. Dam construction, pollution, and erosion also have an impact on each one of these animals. Since many of the animals found in the river ecosystem are related in some way, they are all affected by even small changes in the river.

Wood Turtle (Glyptemys insculpta) Beaver

Wood Turtle (Glyptemys insculpta)

Wood turtles live in sandy bottomed streams and rivers. You may see wood turtles around logs or banks in rivers and streams enjoying the sun. They are considered to be a species of special concern in Michigan.

Beaver (Castor canadensis)

Beavers are found in streams and lakes in both remote and settled areas. Using their huge front teeth, they cut down trees and large branches. They use the trees for food as well as for building their homes. Beavers build dams along rivers and streams using the trees they cut down.
