keystone species

Keystone species form and maintain a complex web of life.

​

​

One example of a keystone species is the beaver. Beavers cut down trees and build dams on rivers. This changes the ecosystem by turning a river into areas of ponds and marshes. Many different species can live in the pond and marsh environments that are made by beavers.
