Lungtalanana (Clarke Island) Survey - 2014
In February 2014 an unplanned bushfire of high intensity swept across the island consuming over 80% of the island. The fire provided an opportunity to investigate the response of fauna and flora to this fire, and the interaction with the remnant vegetation. Additionally the fire resulted in increased access across the island allowing for geomorphology surveys at greater detail.
Clark Island Survey
Also known as Clarke Island, lungtalanana is the third largest island within the Furneaux Group located on the eastern edge of Bass Strait, to the north-east of mainland Tasmania. Approximately 8230 hectares in size lungtalanana is situated on the edge of Banks Strait at 40°32’15” latitude, 148°10’25” longitude.
- Some 190 terrestrial arthropod species were recorded, significantly boosting the known fauna for the island.
- Some 223 coastal marine mollusc species were recorded, significantly boosting the previously recorded numbers.
- We recorded evidence of eight species of terrestrial mammal on Island, with six of these species being classified as introduced animals. The two native species recorded represent only 20% of the native mammal fauna previously recorded from the island.
- Bird surveys identified 62 species, 24 of these were confirmed or suspected as breeding on the island and 7 were new records. The seabird and shorebird fauna remained relatively intact but foliage gleening, mid-storey and ground dwelling species were significantly impacted, though likely to be restored over time.
- Eight species of reptile and four species of amphibian were detected on lungtalanana. All species detected are commonly found on offshore islands in the Furneaux Group.
