Management Plan for Specially Protected Area No. 8 Dion Islands, Marguerite Bay, Antarctic Peninsula
ANNEX TO RECOMMENDATION XVI-6 Management Plan for Specially Protected Area No. 8 Dion Islands, Marguerite Bay, Antarctic Peninsula 1. Geographical location The Dion Islands (67°52'S, 68°43'W) are a small group of low-lying rocky islands lying about 13 km south of the southern end of Adelaide Island, in the north- western part of Marguerite Bay. 2. Management Plan (i) Description of Area The Area comprises all of the Dion Islands archipelago, which lie within an area of about 12 km2, together with the intervening sea. The islands and islets are small, rocky and often precipitous, notably Emperor Island which is also the highest (46 m altitude). The main islands are the largest of the Courtier Islands group (c. 8 ha), Emperor Island (c. 5 ha) and the largest of the Consort Islands group (c. 3 ha). Low lying areas occur on the two largest islands. There are a few small permanent ice patches, but there are no streams or permanent pools. (ii) Reason for designation The Area possesses the only known breeding population of Emperor penguins (Aptenodytes forsteri) on the west side of the Antarctic Peninsula. It is situated on a low-lying raised beach and rocky headland in the south-eastern part of Emperor Island. It is also the most northerly and probably the smallest colony (annual numbers fluctuate between about 50 and 500 pairs), and is one of only two in which breeding occurs on land (see also SPA No. 1). It is also the most isolated Emperor colony, being about 2,500 km (by sea) from the nearest other known rookery. -

Species Status Assessment Emperor Penguin (Aptenodytes Fosteri)
SPECIES STATUS ASSESSMENT EMPEROR PENGUIN (APTENODYTES FOSTERI) Emperor penguin chicks being socialized by male parents at Auster Rookery, 2008. Photo Credit: Gary Miller, Australian Antarctic Program. Version 1.0 December 2020 U.S. Fish and Wildlife Service, Ecological Services Program Branch of Delisting and Foreign Species Falls Church, Virginia Acknowledgements: EXECUTIVE SUMMARY Penguins are flightless birds that are highly adapted for the marine environment. The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species. Emperors are near the top of the Southern Ocean’s food chain and primarily consume Antarctic silverfish, Antarctic krill, and squid. They are excellent swimmers and can dive to great depths. The average life span of emperor penguin in the wild is 15 to 20 years. Emperor penguins currently breed at 61 colonies located around Antarctica, with the largest colonies in the Ross Sea and Weddell Sea. The total population size is estimated at approximately 270,000–280,000 breeding pairs or 625,000–650,000 total birds. Emperor penguin depends upon stable fast ice throughout their 8–9 month breeding season to complete the rearing of its single chick. They are the only warm-blooded Antarctic species that breeds during the austral winter and therefore uniquely adapted to its environment. Breeding colonies mainly occur on fast ice, close to the coast or closely offshore, and amongst closely packed grounded icebergs that prevent ice breaking out during the breeding season and provide shelter from the wind. Sea ice extent in the Southern Ocean has undergone considerable inter-annual variability over the last 40 years, although with much greater inter-annual variability in the five sectors than for the Southern Ocean as a whole. -
Emperor Island, Dion Islands, Marguerite Bay, Antarctic Peninsula
From Measure 1 (2002) Management Plan for Antarctic Specially Protected Area No. 107 EMPEROR ISLAND, DION ISLANDS, MARGUERITE BAY, ANTARCTIC PENINSULA 1. Description of values to be protected The Dion Islands (Latitude 67°52’ S, Longitude 68°42’ W), on the western side of the central Antarctic Peninsula in north-western Marguerite Bay, were originally designated as Specially Protected Area (SPA) No. 8 through Recommendation IV-8 in 1966 after a proposal by the United Kingdom. All of the islands in the Dion Islands archipelago were included. Values protected under the original designation were described as the presence of the only colony of emperor penguins (Aptenodytes forsteri) known to exist on the west side of the Antarctic Peninsula and that the isolation of this colony from others of the same species makes it of outstanding scientific interest. A management plan for the Area was adopted through Recommendation XVI-6 (1990), which reaffirmed the values of the Area. The boundaries were extended to include the intervening sea between the islands to ensure protection of the emperors at sea or on sea-ice in the immediate vicinity. Attention was drawn to the additional important value of the colony being one of only two known in which breeding occurs on land. It was also noted as the most northerly and probably the smallest of Emperor colonies, with annual numbers fluctuating around 150 pairs. The values of the emperor penguin colony are reaffirmed in this revised management plan. The boundaries of the Area are now defined more precisely. -

Avian Island, Marguerite Bay, Antarctic Peninsula
Measure 2 (2013) Annex Management Plan for Antarctic Specially Protected Area No. 117 AVIAN ISLAND, MARGUERITE BAY, ANTARCTIC PENINSULA Introduction The primary reason for the designation of Avian Island, Marguerite Bay, Antarctic Peninsula (67°46'S, 68°54'W; 0.49 km2) as an Antarctic Specially Protected Area (ASPA) is to protect environmental values and primarily the abundance and diversity of breeding seabirds on the island. Avian Island is situated in northwestern Marguerite Bay, 400 m south of Adelaide Island on the western side of the central Antarctic Peninsula. It was originally designated as Site of Special Scientific Interest (SSSI) No. 30 under Recommendation XV-6 in 1989 after a proposal by the United Kingdom. Included was the island together with its littoral zone, but excluded was a small area near a refuge on the northwestern coast of the island. Values protected under the original designation were described as the abundance and diversity of breeding seabirds present on the island, that the southern giant petrel (Macronectes giganteus) colony is one of the most southerly known breeding population of this species, and that the blue-eyed cormorants (Phalacrocorax atriceps) are breeding close to the southern limit of their range. The Area was therefore considered of outstanding ornithological importance, meriting protection from unnecessary human disturbance. Designation as an SSSI was terminated with redesignation of Avian Island as a Specially Protected Area (SPA) through Recommendation XVI-4 (1991, SPA No. 21) after a proposal by the United Kingdom. The boundaries were similar to the original SSSI, but included the entire island and the littoral zone without the exclusion zone near the refuge on the northwestern coast. -
