Keystone species

A keystone species is a species, typically an animal or plant, which has large effect on other organisms within the same ecosystem. Keystone species are for example large predators such as wolves or sea otters, which regulate the numbers of their prey.

Keystone species also include so called “engineers” such as beavers or elephants, which can alter the environment that other species benefit from it.
