The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [1] [2] 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. [3]
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 ...

[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]
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 ...
One of the most widely-understood and studied keystone species is the beaver, whose extinction in many places of the world due to over-hunting for its fur as well as human development vastly ...
Grazing species such as plains bison, which is another keystone species, the pronghorn, and the mule deer have shown a proclivity for grazing on the same land used by prairie dogs. [26] Beaver dam, an animal construction which has a transformative effect on the environment. The beaver is a well known ecosystem engineer and keystone species. It ...
The semi-aquatic mammals, hunted to extinction centuries ago, are key to helping tackle the nature and climate crises, conservationists argue.
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 ...
