Document 3: Saint Barthélemy: Saint-Barthélemy has a marine nature reserve, known as the Reserve Naturelle that covers 1.200 ha, and is divided into 5 zones all around the island to form a network of protected areas. The Reserve includes the bays of Grand Cul de Sac, Colombier, Marigot, Petit Cul de Sac, Petite Anse as well as waters around offshore rocks such as Les Gross Islets, Pain de Sucre, Tortue and Forchue. The Reserve is designed to protect the islands coral reefs, seagrass and endangered marine species including sea turtles. The Reserve has two levels of protection, the yellow zones of protection where certain non-extractive activities, like snorkeling and boating, are allowed and the red zones of high protection where most activities including SCUBA are restricted in order to protect or recover marine life. Anchoring is prohibited in the Reserve and mooring buoys are in place in some of the protected bays like Colombier

Document 5: Legends of the coco de mer: Nut and tree of the coco de mer, a rare species of palm tree native to the Seychelles archipelago in the Indian Ocean, is the subject of various legends and lore. Coco de mer is endemic to the Seychelles islands of Praslin and Curieuse. Before the Seychelles were discovered and settled, nuts of this species were sometimes carried by the ocean currents to distant shores, such as those of the Maldives, where the tree was unknown. These floating nuts did not germinate. The exceptional size and suggestive form of the nut, the circumstances of its discovery, and some unusual qualities of the trees have given rise to several legends.
Document 6: Norfolk Island: Norfolk Island has 174 native plants; 51 of them are endemic. At least 18 of the endemic species are rare or threatened. The Norfolk Island palm (Rhopalostylis baueri) and the smooth tree-fern (Cyathea brownii), the tallest tree-fern in the world, are common in the Norfolk Island National Park but rare elsewhere on the island. Before European colonization, most of Norfolk Island was covered with subtropical rain forest, the canopy of which was made of Araucaria heterophylla (Norfolk Island pine) in exposed areas, and the palm Rhopalostylis baueri and tree ferns Cyathea brownii and C. australis in moister protected areas. The understory was thick with lianas and ferns covering the forest floor. Only one small tract (5 km2) of rainforest remains, which was declared as the Norfolk Island National Park in 1986.

Document 10: Saint Barthélemy: Agricultural production on the island is difficult given the dry and rocky terrain, but the early settlers managed to produce vegetables, cotton, pineapples, salt, bananas and also fishing. Sweet potato is also grown in patches. The islanders developed commerce through the port of Gustavia. Duty-free port attractions, retail trade, high-end tourism (mostly from North America) and its luxury hotels and villas have increased the island's prosperity, reflected in the high standard of living of its citizens.

Document 12: Saint Barthélemy: Marine mammals are many, such as the dolphins, porpoises and whales, which are seen here during the migration period from December till May. Turtles are a common sight along the coastline of the island. They are a protected species and in the endangered list. It is stated that it will take 15–50 years for this species to attain reproductive age. Though they live in the sea, the females come to the shore to lay eggs and are protected by private societies. Three species of turtles are particularly notable. These are: The leatherback sea turtles which have leather skin instead of a shell and are the largest of the type found here, some times measuring a much as 3 m (average is about 1.5 m) and weighing about 450 kg (jellyfish is their favourite diet); the hawksbill turtles, which have hawk-like beaks and found near reefs, generally about 90 cm in diameter and weigh about 60 kg and their diet consists of crabs and snails; and the green turtles, herbivores which have rounded heads, generally about 90 cm in diameter and live amidst tall sea grasses.
Document 13: Saint Barthélemy: As the terrain is generally arid, the hills have mostly poor soil and support only cacti and succulent plants. During the rainy season the area turns green with vegetation and grass. The eastern part of the island is greener as it receives more rainfall. A 1994 survey has revealed several hundred indigenous species of plants including the naturalized varieties of flora; some growing in irrigated areas while the dry areas are dominated by the cacti variety. Sea grapes and palm trees are a common sight with mangroves and shrubs surviving in the saline coastal swamps. Coconut palm was brought to the island from the Pacific islands. Important plants noted on the island are:
Document 14: John Burgoyne: John Burgoyne is best known for his role in the American Revolutionary War. He designed an invasion scheme and was appointed to command a force moving south from Canada to split away New England and end the rebellion. Burgoyne advanced from Canada but his slow movement allowed the Americans to concentrate their forces. Instead of coming to his aid according to the overall plan, the British Army in New York City moved south to capture Philadelphia. Surrounded, Burgoyne fought two small battles near Saratoga to break out. Trapped by superior American forces, with no relief in sight, Burgoyne surrendered his entire army of 6,200 men on 17 October 1777. His surrender, says historian Edmund Morgan, "was a great turning point of the war, because it won for Americans the foreign assistance which was the last element needed for victory". He and his officers returned to England; the enlisted men became prisoners of war. Burgoyne came under sharp criticism when he returned to London, and never held another active command.
