37-794: The Sir Joseph Banks Group is an archipelago in the Australian state of South Australia located in Spencer Gulf about 20 kilometres (12 mi) off the eastern coast of the Eyre Peninsula . It consists of 21 islands of which eighteen are in the Sir Joseph Banks Group Conservation Park while the surrounding waters are in the Sir Joseph Banks Group Marine Park . It is considered to be an important seabird breeding site . The islands are low-lying, with
74-494: A business venture which failed and was then abandoned. A 1940 account of wildlife of the island group states: "There are... many penguins, quail, fairy-terns and other sea-birds on the islands. Cape Barren geese breed there in great numbers and the majority of Cape Barren geese in the Adelaide Zoo came from these islands. Along the beaches I found many beautiful shells, some no bigger than a threepenny bit, and others as large as
111-556: A group of five whales at once from the island. In 1926, Spilsby Island supported thousands of terns and "numbers of" little penguins. The observers noted the southern end of Reevesby Island was a roost for mutton-birds and rock parrots. In 1926, English Island was described as "teeming" with seals and thousands of breeding cormorants. Each nest contained one, two or three pale greenish eggs. Australian sealions were present at Kirby Island as observed by Matthew Flinders in 1802 and by others at English Island in 1935, 1937. and 1940. In 1937,
148-519: A mild wonder at the appearance of the intruder. You can walk among them: they do not move, except to follow you with their eyes." In 2006, the Spilsby Island population was estimated at 2000-3000 birds. In 2010 the population was estimated to be less than 100 birds. In 2011, the population was described as "few". Landholders and conservation groups report that numbers in Spencer Gulf have crashed since
185-416: A piece of rock stuck in her hull. The fishing cutter Edith was wrecked near Spilsby Island in 1897. There were no deaths. She lies off Spilsby Island's south-western shore. In 1899, a vessel ran aground or was wrecked on Buffalo Reef. In September 1903, the fishing cutter Jessica was wrecked and its crew found a week later on Stickney Island. They had survived on fish and no other provisions. In 1920
222-674: A sea containing a small number of scattered islands. Archipelagos are sometimes defined by political boundaries. For example, while they are geopolitically divided, the San Juan Islands and Gulf Islands geologically form part of a larger Gulf Archipelago. The word archipelago is derived from the Ancient Greek ἄρχι-( arkhi- , "chief") and πέλαγος ( pélagos , "sea") through the Italian arcipelago . In antiquity , "Archipelago" (from Medieval Greek * ἀρχιπέλαγος and Latin archipelagus )
259-437: A small dinner plate, and many varieties of seaweed spread over the seafloor." During a 1941 demonstration of the two-way radio system which allowed conversations between Reevesby Island and the mainland for the first time, resident Mrs R. Adams described hundreds of Cape Barren geese nesting on the island, swimming with a seal and said that there was a large penguin burrow under a windmill. She also recounted an occasion when saw
296-414: A submerged rock. The crew made it to Reevesby Island, and items of value were salvaged from the vessel before it sank. She lies south-southwest of Hareby Island. In 1891, the iron-hulled ship Theophane ran aground on one of the islands. All twenty-six people aboard were saved. The ship had departed from Port Pirie and was bound for Newcastle. Theophane was towed to Port Lincoln several days later with
333-487: A visit to the islands in 1839. He noted "plenty" of little penguin , Cape Barren geese and other birds. A holiday-maker visiting the Sir Joseph Banks group in 1923 noted the presence of little penguins, commenting that "On every island there are hundreds of nests,or rather roosts, of the fairy penguins, with their meek faces poking up under the barest shelter." Little penguins were also observed by field naturalists of
370-457: Is a descriptive system widely adopted in Australia to describe different types of vegetation is based on structural characteristics based on plant life-form , plus the height and foliage cover of the tallest stratum or dominant species . For shrubs that are 2–8 metres (6.6–26.2 ft) high, the following structural forms are categorized: For shrubs less than 2 metres (6.6 ft) high,
407-690: Is unknown if anyone ever set foot on the islands prior to the first confirmed European discovery in 1802. The islands were named by Matthew Flinders on 23 February 1802 on his voyage of exploration in HMS Investigator . The group is named after Sir Joseph Banks , who was a sponsor of the Investigator voyage. Many islands in the group are named after places in Flinders and Banks' home county of Lincolnshire , England . The name of Reevesby Island allegedly honors Banks' country residence, Revesby Abbey , though

Interior scrublands occur naturally in semi-arid areas where soils are nutrient-poor, such as on the matas of Portugal , which are underlain by Cambrian and Silurian schists . Florida scrub is another example of interior scrublands. Some vegetation types are formed of dwarf-shrubs : low-growing or creeping shrubs. These include
481-750: The Mediterranean scrub biome , located in the five Mediterranean climate regions of the world. Scrublands are most common near the seacoast and have often adapted to the wind and salt air of the ocean. Low, soft-leaved scrublands around the Mediterranean Basin are known as garrigue in France , phrygana in Greece , tomillares in Spain , and batha in Israel . Northern coastal scrub and coastal sage scrub occur along
518-537: The McCoy Society made an expedition to the Sir Joseph Banks group, collecting specimens, taking photographs and making film recordings. A large colony of terns was discovered on Kirkby Island and a "huge colony" of fairy terns on Langton Island. The Kirby Island observation was of a "very numerous colony" of the Caspian tern. Motion-picture film recordings of the tern colony were made. Penguins were noted by Robert Cock on
555-559: The McCoy Society who visited the islands in 1936. In 1939 an observer noted that the penguins were not as numerous in the Banks Group as they were on some islands outside of Spencer Gulf. Coarse mapping of breeding sites of Little penguins occurred during a 1996 survey of South Australia's offshore islands. It suggested that sites were widely distributed around the Group, potentially occurring on all islands. As of 2011, several penguin colonies in
592-773: The Sir Joseph Banks Group Conservation Park with the waters surrounding the islands are protected by the Sir Joseph Banks Group Marine Park . The archipelago has been identified by BirdLife International as an Important Bird Area (IBA) known as the Sir Joseph Banks Group Important Bird Area because it supports over 1% of the world populations of white-faced storm petrels (with up to about 180,000 breeding pairs), Cape Barren geese (up to about 1200 individuals), black-faced cormorants (from 3000 to 5000 breeding pairs), and, probably, of Pacific gulls . Other seabirds which breed in
629-600: The Sir Joseph Banks Group were listed for private sale. The lot represented 2,000 acres of property in total, spread over the group. Blyth Island, Boucaut Island, Duffield Island, English Island and Sibsey Island obtained protected area status as fauna conservation reserves declared under the Crown Lands Act 1929-1966 on 16 March 1967. In 1847, the Governor Gawler was shipwrecked at the group after striking

703-533: The early 2000s. Little penguins have been recorded on Reevesby Island. In 1907, the colony was mentioned by Douglas Mawson from the Australasian Association for the Advancement of Science: "The cavities in the limestone, which have been hollowed out by the sea, were found to contain a very large number of penguins." A little penguin burrow had been dug under a windmill on Reevesby Island in 1941. In 2009
740-573: The following structural forms are categorized: Similarly, shrubland is a category used to describe a type of biome plant group. In this context, shrublands are dense thickets of evergreen sclerophyll shrubs and small trees, called: In some places, shrubland is the mature vegetation type, and in other places, the result of degradation of former forest or woodland by logging or overgrazing , or disturbance by major fires. A number of World Wildlife Fund biomes are characterized as shrublands, including: Xeric or desert scrublands occur in
777-493: The group are believed to be in decline. As of June 2011, the colony of little penguins on Spilsby Island is believed to be in decline. "Numbers of" little penguins were present on the island in 1926. In 1935, the population was described by a visitor: "All around the shores of Spilsby the quaint, pretty little fairy penguins have their burrows. Sitting bolt upright, their short, hair-like plumage dark blue, with white fronts, they look at human beings with eyes which hold no fear, only

#1732851087763814-456: The group were offered for a seven year term. Sawyer held leases on multiple islands from 1871 until 1884. The lease was later held by the Scruby family, who also leased Stickney Island. In 1885, leases were offered on Langton, Spilsby, Sibsey and Stickney islands. Sawyer secured the leases on Langton and Stickney islands, while Spilsby Island was let to two men: Bishop and Wetherstone, and Sibsey Island
851-413: The highest point on Spilsby of about 50 metres (160 feet) They consist mainly of a granite base beneath limestone and are usually capped with calcrete or sandy soil. Reevesby and Spilsby are the largest islands in the group. Spilsby Island is privately owned and continues to be grazed by sheep, as well as holding a few holiday cottages . The group consists of the following islands: One of
888-441: The islands was known by the alternative name, Milne Island, in the 19th century. Visits to the islands are only possible by boat, with the closest mainland access point being the coastal town of Tumby Bay , 22 kilometres (14 miles) to the north-west. Some islands are not open to the general public because of their environmental sensitivity. There is no evidence to indicate usage by Indigenous Australians in prehistoric times. It
925-613: The ketch Ina was stranded at Sibsey Island. The ketch Eleanor ran aground on reef near Kirkby Island in 1930 and was abandoned there. It was carrying a cargo of wheat from Port Neill enroute for Port Lincoln at the time. Most islands are vegetated with low shrubland dominated by nitre bush or African boxthorn . Some support tall shrubland dominated by coastal boobialla or coastal daisybush . Areas of sandy loam may support marsh saltbush . The larger islands retain patches of woodland . Islands previously used for grazing sheep have introduced grasses and burr medick . As well as
962-445: The native death adders , tiger snakes , and several species of lizard including goannas , many of the islands have introduced mammals such as feral cats , house mice or chinchilla rabbits . The archipelago has Australian sea lion breeding colonies. Greater stick-nest rats were reintroduced to Reevesby Island in 1990/91, and black tiger snakes were abundant there in 1937. Chinchilla rabbits were introduced to Spilsby Island as
999-407: The population was estimated to be 1,857 breeding birds. The colony is believed to be in decline, based on unpublished data and declining results of pitfall trap surveys. In 1916, three men became marooned on Sibsey Island. They survived for twelve days on a diet of penguins and penguin eggs. In 2004, there were "few" penguins recorded on Sibsey Island. Eighteen of the islands within the group are in
1036-460: The result of erosion , deposition , and land elevation . Depending on their geological origin, islands forming archipelagos can be referred to as oceanic islands , continental fragments , or continental islands . Oceanic islands are mainly of volcanic origin, and widely separated from any adjacent continent. The Hawaiian Islands and Galapagos Islands in the Pacific , and Mascarene Islands in
1073-401: The result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing . Shrubland may be unsuitable for human habitation because of the danger of fire. The term
1110-646: The shelf. The islands of the Inside Passage off the coast of British Columbia and the Canadian Arctic Archipelago are examples. Artificial archipelagos have been created in various countries for different purposes. Palm Islands and The World Islands off Dubai were or are being created for leisure and tourism purposes. Marker Wadden in the Netherlands is being built as a conservation area for birds and other wildlife. The largest archipelago in
1147-432: The south Indian Ocean are examples. Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. The Farallon Islands off the coast of California are an example. Sets of islands formed close to the coast of a continent are considered continental archipelagos when they form part of the same continental shelf, when those islands are above-water extensions of

1184-496: The spelling is inconsistent. Kirkby Island is named after the then president of the Royal Society . The nearest major population centre to the islands is Port Lincoln , the name of which also refers to Flinders and Banks' Lincolnshire connection. Some of the group's islands were grazed in the 1800s, including Spilsby Island, where a man called J. Sawyer, his wife and children lived with about 800 sheep. In 1869, leases on islands in
1221-548: The world by number of islands is the Archipelago Sea , which is part of Finland . There are approximately 40,000 islands, mostly uninhabited. The largest archipelagic state in the world by area, and by population, is Indonesia .

The company also quarried guano from the Bicker Isles in Boston Bay. Two-way radio communications with Reevesby Island were made possible in 1941. At this time, Reevesby Island was owned by Mr C. Darling and its administration was left to Mrs. R. Adams. In 1949, Reevesby Island and several other islands in
1369-582: Was the proper name for the Aegean Sea . Later, usage shifted to refer to the Aegean Islands (since the sea has a large number of islands). Archipelagos may be found isolated in large amounts of water or neighbouring a large land mass. For example, Scotland has more than 700 islands surrounding its mainland, which form an archipelago. Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots , but may also be
