How do beavers build giant dams?
With their ability to build dams across streams, beavers are like architects who can restructure the surrounding ecosystem.
The beaver is a primarily nocturnal, semi-aquatic mammal of the family Beaveridae, order Rodentidae .
Beavers are known for their damming, canal digging, and nesting skills. By building dams across streams, beavers are like architects who can restructure the ecosystem around them. They are the second largest rodents in the world (after the capybara). Their colonies build one or two dams to create deep, still water to protect against predators and to keep food and building materials afloat.
