Conservation
Capybaras play an important role in South American wetland and grassland ecosystems by grazing vegetation, dispersing seeds, and serving as prey for large predators, which helps maintain ecological balance. While not endangered, they face threats from habitat loss, wetland drainage, hunting, and human–wildlife conflict as development expands. Conservation efforts focus on wetland protection, sustainable land management, and regulated use to ensure capybara populations remain stable and ecosystems stay healthy.​
