Summary by Krater

This video explores how beavers prepare for winter by felling trees, building dams and canals, and caching branches underwater, while also detailing how moose interact with these beaver habitats during autumn.

From the video

Answers: How do beavers prepare for winter?

• beaver tree felling
• beaver dam and canal construction
• beaver winter preparation
• moose foraging in beaver ponds

What it concludes

• Beavers chew through tree trunks just enough to make them unstable and let the wind finish the job.
• Beaver ponds and canals protect them from predators and allow them to forage far into the forest.
• Beavers cache branches underwater to feed from their food larder during winter when the lake freezes.
• Moose frequently feed on sodium-rich weeds in shallow beaver ponds but must compete with beavers for twigs and branches.
