For about 150 years, Massachusetts had no beavers at all. A few wandered in from New York in 1928, three more were set free in Lenox in 1932, and the state's last estimate is about 70,000. Right now they're sinking branches into the mud at the bottom of the pond: a pantry they'll swim out to under the ice all winter.

Flat green rosettes of wild plants stay green on the ground all winter
Queen Anne's lace, mullein, and thistle wait out the cold as flat circles of leaves pressed to the soil, where some soak up enough sun to sit warmer than the air. Crouch at a lawn edge and count the leaves on one.
