In 2014, a review of beaver dams as stream restoration tools proposed that an ecosystem approach using riparian plants and beaver dams could accelerate repair of incised, degraded streams versus physical manipulation of streams. [61] The province of Alberta published a booklet in 2016 providing information on using beaver for stream restoration ...
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
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 ...

Beavers feed on wood, bark, cambium, [72] branches, twigs, roots, buds, [72] leaves, stems, sprouts, and in some cases, the sap and storax of pine and sweetgum. [42] When herbaceous plants are actively growing, they make up much of the beaver's diet. In the winter, beavers switch to woody plants and the food they have stored over the winter.
Structures formed from plant material include beaver dams, which are constructed by foraged branches and sticks. [22] The dam is a wall of sticks constructed on a moving water source, which forces the water to collect in one area and to stop flowing. [22] Beavers begin to build a dam in an area where rocks and other debris slow the flow of the ...
