Beaver dam - Wikipedia
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 ...
Beaver dams: How structure, flow state, and landscape setting regulate ...
2021年9月1日 · The survey of intrinsic beaver dam properties revealed significant differences in dam structure across different sites. Physical differences in dam structure altered the dynamics and variance of pond storage and certain dam attributes related to the landscape setting.
Dam builders and their works: Beaver influences on the structure …
2021年7月1日 · Our key findings are that a complex of beaver dams can increase surface and subsurface water storage, modify the reach scale partitioning of water budgets, allow site specific flood attenuation, alter low flow hydrology, increase evaporation, increase water and nutrient residence times, increase geomorphic heterogeneity, delay sediment transport...
Why do beavers build dams? - BBC Science Focus Magazine
Answer: Beavers build dams to protect themselves from predators, such as bears or wolves. Beavers don’t actually live in the dams, but in the deep pond of water that dams create. In this …
Beaver dams: How structure, flow state, and landscape setting …
2021年9月1日 · Beaver can build dams in a wide range of landscapes and conditions. This versatility leads to a large variety of dam types. A categorization of dams based on the way water flows through each dam structure was conceptualized by Woo and Waddington (1990).

2022年9月22日 · Beavers build dams across streams to create a pond where they can build a "beaver lodge" to live in. These ponds provide protection from predators like wolves, coyotes, or mountain lions. What do beavers use to build their dams? Beavers build their dams out of trees and branches that they cut using their strong incisor (front) teeth! They also ...

Therein, a BDA is a temporary structure that is designed to promote the process of beaver dam activity by beaver. BDAs can sometimes be used to mimic beaver dam activity, but that is typically for a short period of time (e.g. to release translocated beaver into safe ponds, or to foster expansion of riparian vegetation).
