They sure aren't in danger of extinction in the US. Lots of downed trees along the lake where I live!

Beavers are very clever of building the dams, while cutting down the trees near the waters. I loved watching them work and they are truly amazing animals.

Would be best to actually have the second heaviest rodent listed among the answers, or perhaps a change in question wording. Reported.
