The Isle of Wight is one of the few places in England where the red squirrel is still flourishing; no grey squirrels are to be found. There are occasional sightings of wild deer, and there is a colony of wild goats on Ventnor's downs. Protected species such as the dormouse and rare bats can be found. The Glanville fritillary butterfly's distribution in the United Kingdom is largely restricted to the edges of the island's crumbling cliffs.
