Site description Kidney Island is roughly kidney-shaped, as its name suggests, and lies about 0.3 miles (0.5 km) off the coast of East Falkland, at the southern entrance to Berkeley Sound. It is largely low lying, with the highest point at 18 m above sea level, and is almost covered with mature Tussac. There are boulder beaches on eastern and western coasts, a large sand bay facing south-west and near-vertical cliffs along much of the northern coastline. Cochon Island is a small island lying adjacent to Kidney Island, formed from steeply dipping rocks, which rise to over 30 m at the island’s highest point. The soil is generally thin and vegetation is limited to Tussac, Wild Celery and Stonecrop, which vary in density throughout the rocky ridges.

Other biodiversity Both islands are used by Southern Sea Lions for hauling out, and they can often be found resting in Tussac, sometimes well inland and at the top of long slopes, but apparently they do not now breed there. At least 26 species of flowering plants have been recorded in recent years on Kidney Island, including the two endemic ragworts, Woolly Falkland Ragwort Senecio littoralis and Smooth Falkland Ragwort Senecio vaginatus. The Swordgrass (sedge) Carex trifida grows well with shorter Tussac. Preliminary collections and surveys of the invertebrate fauna and flora have been made because Kidney is an accessible, mature Tussac island.
