Answers: How do beavers prepare for winter?
- beaver tree felling
- beaver dam and canal construction

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.
