The vertebrate animals of Tasmania (mammal, birds, reptiles, frogs and fish), are of great national and international interest and an important component of Tasmania's natural heritage. Tasmania serves as a refuge for many species which, especially over the past 200 years, have become increasingly rare or extinct across the rest of the continent, such as the bettong, eastern quoll and pademelon.
