Site description Stonington Island is located approximately 2 km north of Neny Island, Neny Fjord, on the Fallièrs Coast of the Antarctic Peninsula. The IBA comprises a 500 ha circular area centred on the geographic position of the bird breeding site as reported in Lynch et al. (2008) (68°11' S, 67°0' W).

Stonington Island is a small island with relatively flat areas of boulders interspersed with rocky outcrops (ATS Visitor Site Guide, accessed 06/08/2010). The site supports at least seven lichen species and two moss species. Two former stations are located on Stonington Island: Base E (UK) built in 1946, and East Base (US) established in 1940. Base E was closed in 1975 and is now designated as Historic Site No. 64 under the Antarctic Treaty for its historical value in early exploration of the region. East Base is designated as Historic Site No.55 to protect buildings and artefacts in the area.

The nearest permanent scientific station is San Martin (Argentina) located approximately 7 km to the north on Barry Island in the Debenham Islands.

Key Biodiversity Imperial Shags (Phalacrocorax atriceps) breed on Stonington Island and 135 chicks were recorded in February 2007 (Lynch et al. 2008). South Polar Skuas (Catharacta maccormicki) and Antarctic Terns (Sterna vittata) are also confirmed breeders at the site (Naveen 2003).
