Little Dog Island is a square, flat granite island, with an area of 83 ha, in south-eastern Australia. It is part of Tasmania’s Great Dog Island Group, lying in eastern Bass Strait between Flinders and Cape Barren Islands in the Furneaux Group. It is a game reserve. It was previously grazed, a usage now ceased.[1] 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.[2]
Recorded breeding seabird and wader species are Little Penguin, Short-tailed Shearwater (over half a million pairs) and Pied Oystercatcher. The Sooty Oystercatcher, Caspian Tern and White-fronted Tern have bred on an isolated rock 200 m north of the island. The Swamp Harrier has bred on the island. Reptiles present include the Metallic Skink and Tiger Snake. The Growling Grass Frog has been recorded.[1]
