Otter, Water voles and Mink share similar habitat, being aquatic mammals adapted to life in and around fresh water and even estuaries and sea coasts.
Otters and water voles are native to the British Isles and are a part of the natural riparian ecosystem. Mink, on the other hand, are an introduced North American species causing great damage to our native aquatic fauna – in particular to the once-common Water vole, which through mink predation and loss of habitat, has suffered a catastrophic decline in populations.
