A beaver dam is a natural structure created by beavers using tree trunks, branches, and mud to block a river or stream and create a pond. However, there are several synonyms for this term, including an engineering marvel created by beavers, rodent-made obstruction, a beaver lodge, and a natural barrier. A beaver dam can also be known as a beaver pond, a beaver-built dam, or simply a beaver barrier. In addition, a beaver dam can be referred to as a wildlife habitat, as it provides shelter and living space for many other wildlife species. Regardless of the term used, a beaver dam is an important component of the ecosystems that they inhabit.
