Question: What island is the only home to the snake commonly known as The Golden Lancehead?

full_context: Document 1: Pseudechis: The genus Pseudechis contains the group of elapids commonly referred to as the black snakes. These snakes are found in every Australian state with the exception of Tasmania and some species are found in Papua New Guinea. They inhabit a variety of habitat types, from arid areas to swampland. All species are dangerous ("Pseudechis" signifying "like a viper", Greek "echis") and can inflict a potentially lethal bite. Most snakes in this genus reach about 2 metres and vary in colour. Some species are brown, where others are black. The most recognisable and widespread species in the genus are the red-bellied black snake ("Pseudechis porphyriacus") and the Mulga snake (king brown) ("Pseudechis australis"). These snakes feed on lizards, frogs, birds, small mammals and even other snakes. All species lay eggs, except the red-bellied black snake. The genus "Pailsus" is a synonym of "Pseudechis", and more work is needed to understand species limits among the smaller species of the group.

Document 8: Brook Islands National Park: The Brook Islands National Park is a national park in Cassowary Coast Region, Queensland, Australia, 1246 km northwest of Brisbane, with an area of 0.9 km. It was established in 1994 and comprises three islands - North, Tween and Middle - which lie off the coast 7 km north-east of Cape Richards on Hinchinbrook Island and 30 km east of the nearest mainland town of Cardwell. The fourth island of the Brooks group, South Island, is not part of the national park but is protected by the Great Barrier Reef Marine Park Authority. Public access to the three islands in the national park is prohibited in order to protect breeding birds, especially the Torresian imperial-pigeon. The islands have no roads, walking tracks or other facilities. Popular activities in the waters around the islands are boating, snorkelling and fishing. The islands are managed by the Queensland Parks and Wildlife Service. The Park's IUCN category is II.

Document 10: Granite Island (South Australia): Granite Island, also known by the Ramindjeri people as Nulcoowarra, is a small island next to Victor Harbor, South Australia, about 80 km south of South Australia's capital city, Adelaide. Although there are no permanent residents, there are buildings and shelters on the island, including a cafe. It is a popular tourist attraction, particularly for people wishing to see little penguins (commonly called "fairy penguins") which live there. The island also supported resident wallabies in the 1980s which captivated visiting tourists. The island is accessible across a causeway from the mainland, either on foot or by catching an antique horse-drawn tram. As of 2015, the private company Oceanic Victor intends to use the island as a departure point to ferry tourists to a new tourist attraction in adjacent waters. Tourists will be able to enter an aquaculture seacage where they will be able to swim with and hand feed southern bluefin tuna, and observe other South Australian marine species.

Document 12: Ilha da Queimada Grande: Ilha da Queimada Grande, also known as Snake Island, one of many Snake Islands around the world, is an island off the coast of Brazil in the Atlantic Ocean. It is administered as part of the municipality of Itanhaém in the State of São Paulo. The island is small in size and has many different types of terrain, ranging from bare rock to rainforest. The island has a temperate climate. The island is the only home of the critically endangered, venomous "Bothrops insularis" (golden lancehead pit viper), which has a diet of birds. The snakes became trapped on the island when rising sea levels covered up the land that connected it to the mainland. This left the snakes to adapt to their environment, increase rapidly in population and render the island dangerous to public visitation. Queimada Grande is closed to the public in order to protect this snake population; access is only available to the Brazilian Navy and selected researchers vetted by the Chico Mendes Institute for Biodiversity Conservation, the Brazilian federal conservation unit.
Document 13: Bothrops erythromelas: Bothrops erythromelas, commonly known as the Caatinga lancehead or the jararaca-da-seca, is a species of venomous snake in the family Viperidae. It is endemic to Brazil. It belongs to reptile class.

Document 15: Vilsandi: The island of Vilsandi, Kihelkonna Parish, Saare County, Estonia is located in the Baltic Sea. It covers an area of some 9 square km and is the westernmost populated island in Estonia. The surrounding waters are shallow and rocky and many ships travelling the Baltic have perished nearby. The island of Vilsandi can be reached by boat, by truck having suitable clearance or on foot by wading from Saaremaa. Much of the island is now part of Vilsandi National Park, which grew from a bird reserve founded in 1910. It is a highly sensitive ecosystem due to the use of the area by many migratory birds as a breeding and nesting ground. Hunting is absolutely prohibited. This park is a popular tourist destination not only for local Estonians, but also people of Finland who are visiting Estonia in greater and greater numbers.
