They create underwater food caches near their lodges to access during the frozen months.

This strategy ensures a steady food supply when ice covers their habitat.

18. Beaver lodges have underwater entrances.

Their homes are accessible only through underwater entrances, protecting them from predators.

Lodges are cozy, with a dry living chamber above water level.

19. Beavers help mitigate flooding.

Their dam-building activities can reduce the impact of flooding by slowing down water flow.

This natural water management is beneficial in flood-prone areas.

20. Beaver dams help create wetlands.

Their dams can transform landscapes, creating wetlands that benefit other species.

These wetlands are crucial for biodiversity and ecosystem health.

21. Are beavers nocturnal?

Yes, beavers are primarily nocturnal, meaning they are most active during the night. They build dams and lodges, working on these structures during the darkness.

22. The fur trade drastically reduced beaver populations.

In the 17th and 18th centuries, beaver fur was highly sought after, leading to overhunting.
