A key stone species is..

• a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. （Ex. Ochre Sea Star, California Mussel)

• species that are native to and found only within a limited area

• a species that has a strong role in structuring a community. A foundation species can occupy any trophic level in a food web (i.e., they can be primary producers, herbivores or predators Ex. kelp).

• Species with a broad ecological niche. They can live in many different places, eat a variety of foods, and tolerate a wide range of environmental conditions. (Ex. flies, human)
