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)
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.
