Environment Keystone Species Impact
Keystone species have disproportionate effects on ecosystems relative to their abundance. Removing them causes dramatic changes. Sea otters prevent sea urchin overgrazing of kelp forests. Wolves control deer populations, allowing forest regeneration. Beavers create wetlands supporting diverse species. Understanding keystone species is crucial for conservation.
