Pollinators of flowering plants are also key stone species as they play an important role in the reproduction process pollination leading to generation of new plantlets. However almost all examples of keystone species are animals that have a huge influence on food webs.
They also provide a safe haven and feeding area for small fish among their roots which reach down through the shallow water.

Keystone species can also be plants. Any organism from plants to fungi may be a keystone species. For example the herbivorous weevil Euhrychiopsis lecontei is thought to have keystone effects on aquatic plant diversity by foraging on nuisance Eurasian watermilfoil in North American waters.
