Yes, the Mongolian Beaver is endangered and has been since 1976. Additional Info: Beavers were hunted, and trapped on a large scale, due to the commercial market for their fur. With no regulations or controls, the beaver was hunted almost to extinction. They depend on wetlands to build and survive, which we drain and use for our own purposes. Today many farmer's, tree farmer's, and other land owner's see the beaver's building as a threat to crops, (both trees, and plants), and livestock, by flooding. The beaver's cut down trees at a staggering rate and the damage to a farmer's crop can have far reaching repercussions, especially if it is a 15-20 year old crop of trees. These farmer's are faced with hard solutions either, having them removed, kill them, or blow the dam up (which will kill them). Proper removal of the Beaver and family, during the correct season, to an area that is protected is recommended. Today in the US, the hunting and trapping of the beaver is controlled and regulated Federally to try and maintain a balance, and the American Beaver has made a good recovery in most areas of the US. But not all species of Beaver have recovered so well in all their regions. According to the IUCN Red List, three different Beaver species are listed as "least concern", this includes the American Beaver. While the US Fish and Wildlife Services Endangered Species List has two species of Beaver listed both with a status of "endangered". For more details, please see the sites listed below.
