Pressure/threats to key biodiversity

Human disturbance – No

Predation by alien species – No

Habitat loss or degradation – Yes - Erosion of the island's coast has impacted on some breeding sites - for example, a large sand dune at the back of Sandy Bay was washed away by wave and storm action. Many burrows would have been lost.

Contamination – No

Natural disaster – Yes - The island is the visible part of the edge of a huge submarine caldera which remains active. A large-scale eruption of the volcano would have a devastating impact on breeding seabirds.

Other - No
