Wikipedia Abstract

The North American beaver (Castor canadensis) is one of two extant beaver species. It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Norway). In the United States and Canada, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, Aplodontia rufa, is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species, Castor fiber, which is native to Eurasia. The North American beaver is an official animal symbol of Canada.

Invasive Species

Castor canadensis (beaver) is native to North America, and has been introduced to Tierra del Fuego in southern South America, Finland, France, Poland and Russia in recent times. In its introduced range, the damming activity of the beaver can cause flooding which can damage forests. They also have the ability to quickly cut down large numbers of trees. In Finland, they compete with native beaver populations. In their native range, they cause flooding on major highways by plugging highway culverts.
