Beavers are known for building dams, canals, and lodges out of wood and other plant materials. They are semi-aquatic rodents that use powerful front teeth to cut wood to build these structures for shelter and transportation of materials. By constructing dams, beavers create deep ponds that provide protection and allow them to float building materials.

 Is a primarily nocturnal, large,
semi-aquatic rodent.
 Beavers are known for
building dams, canals, and
lodges (homes). They are the
second-largest rodent in the
world (after the capybara).
Their colonies create one or
more dams to provide still,
deep water to protect against
predators, and to float food
and building material.
Beavers (Genus Castor)

 Beavers are known for their natural trait of building
dams on rivers and streams, and building their
homes in the resulting pond.
 Beavers build canals to float building materials that
are difficult to haul over land.

4.   They use powerful
front teeth to cut
trees and other
plants that they use
both for building
and for food. In the
absence of existing
ponds, beavers
must construct
dams before
building their
lodges.
 The habitat of the beaver is
the riparian zone, inclusive
of stream bed.

5. 
 The beaver works as a keystone species in an
ecosystem by creating wetlands that are used by
many other species. Next to humans, no other extant
animal appears to do more to shape its landscape.
Beavers potentially even impact climate change.
