Site description Paulet Island is situated ~5 km southeast of Dundee Island, east of Tarabin Peninsula, northern Trinity Peninsula. The island is an ice-free extinct volcanic cone of roughly circular shape of ~1.7 km in diameter and rising to ~350 m (ATS Visitor Site Guide: Paulet Island, accessed 06/08/2010). The IBA comprises all of the island.

Scree slopes lie on the southern and western slopes of the island. A flat terrace to the north and northeast, to which visitor access is restricted, is frequently submerged at high-tide. Historic Site and Monument No. 41 is located on Paulet Island, and comprises a stone hut, rock cairn and grave, which were constructed by survivors from the vessel Antarctic which was wrecked close to the island during the Swedish South Polar Expedition of 1901-04.

The nearest scientific station is Petrel (Argentina), a summer-only facility for up to ~55 people (COMNAP, Antarctic Facilities, accessed 06/08/2010) and located on Dundee Island ~25 km to the northwest.

Key Biodiversity Approximately 100,000 breeding pairs of Adélie Penguins (Pygoscelis adeliae) were recorded breeding around meltwater lakes and on elevated ridges on the northeast of Paulet Island in 1999 (Naveen 2003). A large proportion breed on a flat terrace in the north and northeast of the island. Approximately 465 breeding pairs of Imperial Shag (Phalacrocorax atriceps) were recorded breeding amongst the Adélies in 2007 (Lynch et al. 2008). Previous records indicate most shags nest on a basaltic stack and nearby cliff on the northern shoreline (Naveen 2003). Croxall et al. (1995) estimated 300 pairs of Snow Petrel (Pagodroma nivea) were breeding on Paulet Island in 1992. The Kelp Gull (Larus dominicanus) is also a confirmed breeder whilst the Greater Sheathbill (Chionis alba) and Wilson’s Storm-petrel (Oceanites oceanicus) are frequently observed and may breed in the area (ATS Visitor Site Guide: Paulet Island, accessed 06/08/2010).

Non-bird biodiversity: Weddell Seal (Leptonychotes weddellii) and Antarctic Fur Seal (Arctocephalus gazella) regularly haul out at Paulet Island, whilst Leopard Seal (Hydrurga leptonyx) are frequently observed hunting offshore.
