Summary The Curtis Island IBA supports more than 1% of the global population of Short-tailed Shearwater.
Site description Curtis Island is located north west of Flinders Island in the Bass Strait. Curtis Island is oriented south-west and is dominated by steep cliffs along the coastline. The 1.78m long ridge rises from north to south at a steady rate and is broken into two peaks. The northern peak is rounded and reaches 224.3m high while the southern peak reaches 335.3m high and is square-capped and vegetated. The soils are a mixture of granite gravels and bird-derived organic matter. Curtis Island is a significant island because of its soil type and species diversity (Brothers et al. 2001).
