Why do pikas live in the tundra?

Pikas thrive in the tundra due to its cold climate, which helps them manage heat stress and reduces competition with other herbivores. Their thick fur and small size allow them to adapt to harsh conditions, while their behavior of accumulating and storing vegetation for winter sustenance ensures they have food during the lean months. Additionally, the rocky terrain of tundra habitats provides essential shelter from predators and harsh weather.
