How Do Beavers Prepare A Lodge For Winter
All fall Beaver’s cut Aspen, Willow and Alder trees and make a huge food pile underwater. Beavers will do this until the pond becomes completely iced over.
All winter beavers continue to live in their lodge. Their lodge has two underwater entrances that they use all year long. To construct their lodge beavers pile up cut branches, debris and aquatic vegetation and then coat the structure with mud except for the peak which is left open as an air vent. The structure has two levels: one underwater and one above water which they use as a feeding ledge.
Students look for sign of beaver activity down near the river. The students found this fallen tree which was an invitation to climb!
