Vansittart Island

The island is part of the Franklin Sound Islands Important Bird Area, identified as such by BirdLife International because it holds over 1% of the world populations of six bird species.

[1] Most of the original vegetation of the island has been cleared by the use of fire and by bulldozers with chains, destroying many stands of Oyster Bay pine.

Recorded breeding seabird and wader species are little penguin, Pacific gull, sooty oystercatcher and pied oystercatcher.

Black swans have nested on the island, which is also a refuge for Cape Barren geese.

Echidnas are present, though the Tasmanian pademelon is extinct there.
