Detailed explanation-1: -Beavers are a classic example of allogenic engineers. Beavers help maintain woodland ecosystems by thinning out older trees and allowing young saplings to grow. Converting these trees into timber for dams radically alters woodland meadows and streams, changing them into wetland habitats.
Detailed explanation-2: -Beavers are considered a keystone species for the way they shape their ecosystems by building dams that, in turn, create a wetland habitat in which many other species thrive.
Detailed explanation-3: -Keystone species hold together the complex web of relationships in an ecosystem. They can be animals, plants or microorganisms. Examples of keystone species include starfish, sea otters, wolves and elephants.
Detailed explanation-4: -Beavers increase biodiversity and provide salmon habitat They bring wood into the water, and that wood provides food and shelter for insects, and those insects become food for other species, including salmon.
