Beaver dams: nature’s wildlife bridges!
Beaver dams are nature’s bridges and many animals such as wolves, bears, deer, and the like use them to cross wetlands. This footage is from a few years ago on a large old beaver dam.
A few years back, we used high-resolution aerial imagery to count/digitize all the beaver dams visible on aerial imagery in the Greater Voyageurs Ecosystem (our study area). In total, we identified 9,028 beaver dams in the GVE, which is roughly ~2,000 square kilometers in size.
The average dam was 73 meters/239 feet long meaning that there are 659 kilometers/409 miles of beaver dams in the GVE. Pretty incredible how beavers have altered the landscape!
