More on impacts: Overgrazing by muskrat causes the local extinction of aquatic plants and the destruction of reedbeds and fish nursery areas. Due to its burrowing activity, it degrades river banks and affects river flow. It can exert a strong predation pressure and threaten freshwater mussel and crustacean populations. It could also act as a reservoir of different pathologies and causes damages to agriculture. Muskrat is included in the appendix to the recommendation no 77 of the Council of Europe as a species which has proved to be a threat to biological diversity and for which eradication is strongly recommended.
