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]

Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some ...
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 ...
Beavers at Knapdale have built the ideal habitat for the threatened native water voles to avoid predators
If you know one thing about beavers, it's probably that they build dams. (Here are a few more things: These rodents are second only to humans in their ability to manipulate the environment, and ...
Beaver, Canadian lynx, bobcat, wolverine, and snowshoe hare are all keystone species in the taiga area. These species are keystone because they have learned to adapt to the cold climate of the area and are able to survive year-round. These species survive year-round in taiga by changing fur color and growing extra fur.
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
