Document 2: 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 3: 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 5: 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 6: Charles Edward Callwell: Major-General Sir Charles Edward Callwell (2 April 1859 – May 1928), was an Anglo-Irish officer of the British Army, who served in the artillery, as an intelligence officer, and as a staff officer and commander during the Second Boer War, and as Director of Operations & Intelligence during World War I.

Document 7: Chemical weapons in World War I: The most frequently used chemicals during World War I were tear - inducing irritants rather than fatal or disabling poisons. During World War I, the French army was the first to employ gas, using 26 mm grenades filled with tear gas (ethyl bromoacetate) in August 1914. The small quantities of gas delivered, roughly 19 cm3 per cartridge, were not even detected by the Germans. The stocks were rapidly consumed and by November a new order was placed by the French military. As bromine was scarce among the Entente allies, the active ingredient was changed to chloroacetone.
Document 8: 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 9: Ronald Bruce Campbell: Born in Madras, India, on 14 September 1878, Ronald Bruce Campbell was educated at Bedford School and at the University of Edinburgh. He served in the British Army during the Second Boer War, between 1900 and 1901, and during the First World War, between 1914 and 1918, and was promoted to the rank of Colonel in the Gordon Highlanders in 1922.

Document 10: 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 11: Saint Barthélemy: Other trees of note include the royal palm, sea grape trees in the form of shrubs on the beaches and as 5 to 7 m trees in the interior areas of the island, aloe or aloe vera (brought from the Mediterranean), the night blooming cereus, mamillaria nivosa, yellow prickly pear or barbary fig which was planted as barbed wire defences against invading British army in 1773, Mexican cactus, stapelia gigantea, golden trumpet or yellow bell which was originally from South America, bougainvillea and others.
Document 12: 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 13: Charles Foulkes (British Army officer): Major-General Charles Howard Foulkes CB CMG DSO (1 February 1875 – 6 May 1969) was a Royal Engineers officer in the British Army and also a British international field hockey player who competed in the 1908 Summer Olympics in the bronze medal-winning team. He saw service in World War I and, following the first German use of gas on 22 April 1915 at the Second Battle of Ypres, became Britain's chief advisor on gas warfare. He also advised on the use of gas to suppress the uprisings in Afghanistan (1919) and Waziristan (1920), but gas was never actually deployed in these conflicts.
Document 14: Trang Province: The seal of the province shows a lighthouse bridge above a sea of waves. The lighthouse bridge refers to Trang as a seaport trading with foreign countries.The provincial symbolic flower and tree is the green ebony (Jacaranda filicifolia). The plant was imported from Australia by the same governor who imported the rubber tree, and it quickly got the name "si trang" by the citizens.
