This list shows 28 examples of keystone species in North America, and tells a little about each species and how they’re important to their respective ecosystem.
Why protecting keystone species matters for biodiversity
These animals shape the land and water in ways that help countless other species survive. Understanding and protecting keystone species isn’t just about saving charismatic animals—it’s about preserving the structure and function of entire ecosystems.
How human activities threaten keystone species worldwide
Keystone species are essential for maintaining the structure and health of ecosystems. Their presence or absence can trigger significant changes, affecting biodiversity and ecosystem functions. As environmental conditions shift due to human activities, these species face unprecedented challenges. Addressing the conservation of keystone species is important for preserving ecological balance.
The role of keystone species in ecosystem balance
A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.

Conservation efforts for endangered keystone animals
Without keystone species, ecosystems and all species living in them would experience drastic changes that could threaten their existence. Global ecosystem restoration efforts depend on urgent action to conserve endangered keystone species.
What are keystone species and why are they important?
In ecology, a keystone species is a species that has a disproportionately large impact on its environment relative to its abundance. A keystone species plays a key role in maintaining the health and diversity of an ecosystem and is significant in conservation efforts. A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.
