Beaver and their associated ponds and wetlands may be overlooked as effective wildfire-fighting tools. [71] Eric Collier's 1959 book, Three Against the Wilderness, provides an early description of a string of beaver ponds serving as a firebreak, saving the home of his pioneer family from a wildfire in interior British Columbia.

Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of ...
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 transforms its territory from a stream to a pond or swamp. Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams ...
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 ...
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 ...

Despite being widespread in some beaver-inhabited areas, beaver canals and their environmental effects are much less studied than beaver dams. Beaver primarily develop canals to increase accessibility of river resources, facilitate transport of acquired resources, and to decrease the risk of predation.
