The island, together with its littoral zone, possesses an unusually high collection of marine and terrestrial life and is unique amongst the neighboring islands as a breeding place for six species of native birds. It provides an outstanding example of the natural ecological system of the Antarctic Peninsula area. In addition, Litchfield Island possesses rich growths of vegetation and has the most varied topography and the greatest diversity of terrestrial habitats of the islands in Arthur Harbour. For these reasons, it was designated an Antarctic Specially Protected Area (ASPA) in 1975 and is currently known as ASPA 113.[1]
