Schouten Island Survey
Schouten is a rugged island with the highest point, Mount Storey, 400 m asl. It is surrounded by cliffs, broken by sheltered bays. A north-south fault line exists divides the island where the eastern part of the island is composed of granite while the western part is dolerite overlying sedimentary and supergroup rocks.
Little Penguins and Short-tailed Shearwaters breed on the island, along with other bird species such as the Tasmanian Native-hen. Australian Fur Seals haul out on the eastern side. Reptiles present include the Tasmanian Tree Skink, She-oak Skink, Southern Grass Skink and Three-lined Skink.
- 13 new vegetation communities were recorded, including two new threatened communities of Callitris rhomboidea forest.
- Eleven species of terrestrial mammal on Schouten Island including seven species of bat were recorded for the first time.
- Remarkably, given the history of the island, no exotic rodents were recorded. The only exotic mammal species recorded was the rabbit.
- Sixty bird species were identified on Schouten Island and its surrounding rocks, reefs and islets.The groups comprised 9 seabirds, 3 shorebirds, 7 raptors and 41 bush and pasture species.
- The finding of additional Little Penguin colonies increased the island's total population size and its importance as a breeding location for this species.
