A keystone species is one whose impact on its ecosystem is disproportionately large relative to its abundance. They play a critical role in maintaining the structure and health of an ecosystem, and their removal can lead to significant changes or collapse of the ecosystem. Examples include sea otters, which help control sea urchin populations, and wolves, which regulate herbivore populations.
