Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams.
The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [93] As wetlands are formed and riparian habitats enlarged, aquatic plants colonize newly available watery habitat. Insect, invertebrate, fish, mammal, and bird diversities are also expanded. [94]
Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ecosystem, beavers are considered a keystone ...
Beavers are often called a “keystone” species, which in environmental terms means a species that is vital to the health and sustainability of a particular ecosystem, and without which, the ...
Last year, the department adopted a new policy formally recognizing beavers as a keystone species — those that play an outsized role in maintaining the diversity of their ecosystem — and ...

The Eurasian beaver (Castor fiber) or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum , with only about 1,200 beavers in eight relict populations from France to Mongolia in the ...
