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 ...
The surface of beaver ponds is typically at or near bank-full, so even small increases in stream flows cause the pond to overflow its banks. Thus, high stream flows spread water and nutrients beyond the stream banks to wide riparian zones when beaver dams are present. Finally, beaver ponds may serve as critical firebreaks in fire-prone areas. [59]
Beavers are well known for building dams across streams and constructing their lodges in the artificial ponds which form. When building in a pond, the beavers first make a pile of sticks and then eat out one or more underwater entrances and two platforms above the water surface inside the pile. The first is used for drying off.
Beaver Pond is a body of water in Lincoln, Massachusetts, United States. [1] Today it is part of a conservation area, [2] owned by Lincoln Land Conservation Trust (LLCT), containing ponds, wetlands, forests and meadows. Historically, the land was used for farming.
Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. 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 ...
Ponds that dry up completely each year are often known as vernal pools. Some ponds are produced by animal activity, including alligator holes and beaver ponds, and these add important diversity to landscapes. [5] Ponds are frequently man made or expanded beyond their original depths and bounds by anthropogenic causes.
Beavers diligently plug leaks in their dams because their survival depends upon the cover provided by the water in their pond. If a beaver can detect the flow of pond water into a pipe, it will plug the pipe with mud and sticks. To be successful, a beaver dam pipe must eliminate the sound and feel of water flowing into the pipe.
Beaver Pond's namesake animal was a vital component in the colonial economy. Beaver fur attracted Dutch colonists to the region and the animal appears on the seal of New York City. English settlers arrived in the area in 1656, with permission from the New Netherlands government to build Rustdorp.
