Site description Cuverville Island is a small island lying in the Errera Channel between Rongé Island and Arctowski Peninsula (Graham Land). A permanent ice-cap extends over much of the island, although on the northern slopes there is a series of broad, rocky beaches below steep cliffs. The rocky areas provide suitable breeding sites for penguins. The IBA extent is defined by the island coastline.

Vegetation consists of a range of moss and lichen species as well as both of the two flowering plant species Antarctic hair grass Deschampsia antarctica and pearlwort Colobanthus quitensis (ATS Visitor Site Guide: Cuverville Island, accessed 13/08/2010). Moss cover is extensive at higher elevations.

The nearest scientific station is Gabriel Gonzáles Videla station (Chile), a summer-only facility in Paradise Cove with capacity for up to nine people (COMNAP, Antarctic Facilities, accessed 16/08/2010).
