Falklands Conservation

Site description Forming the southernmost land in the Falklands archipelago, Beauchêne Island is located approximately 33 miles (54 km) south of Porpoise Point, Lafonia. It has not been grazed or permanently settled, is free of introduced predators and its remote location has protected the island from disturbance in recent years. In the north, the island is covered in dense Tussac and the coastline is gently sloping, up to around 30 m high. There are boulder beaches on the western coast. In the south, the land rises to around 70 m with higher cliffs on the eastern coast and fissured steep slopes. The southern quarter of the island is almost bare of vegetation.

Other biodiversity The island is also host to a few breeding Southern Sea Lions and is a major haul-out station for non-breeding animals, which can congregate in numbers of up to a hundred individuals on the northern part of the island. It is remarkable for the paucity of plant species. Two-thirds of its area is covered by Tussac, which here reaches exceptional and luxuriant dimensions. Three other vascular species have been recorded, including Wild Celery Apium australe, Antarctic Starwort Callitrache antarctica and Bittercress Cardamine glacialis.
