A species whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system.

It includes the American alligators, beavers, bees, elephants, gopher tortoises, grizzly bears, hummingbirds, ivory tree corals, jaguars, mountain lions, mycorrhizal fungi, Pacific salmon and prairie dogs. Thus, Mycorrhiza is a keystone species.
