GEOGRAPHY Boigu is approximately 18 km long, and low-lying. It was formed by the accumulation of Alluvial Sediment s deposited by the discharge of nearby New Guinean rivers into the Strait. These sediments built up over time on an old Coral platform which rises from the shallow Continental Shelf , eventually creating the island. Most of the island is subject to extensive periodic flooding, and as a result the community township has been built on the highest ground. Two nearby smaller islands (not permanently settled) are considered as a part of Boigu island, these are Aubisi Island and Moimi Island. ECOLOGY The island is considered part of the New Guinea Mangroves Ecoregion , a subset of the Australasia Ecozone . The interior of the island is sparsely vegetated, and mainly Swampland . The coast is fringed by Mangrove s, which act to protect against the island's sand and mud from sea Erosion . The waters surrounding the island are an important Habitat for Dugong s, an Endangered Species of Sea Mammal . POPULATION Boigu is predominantly inhabited by Indigenous Torres Strait Islanders . According to 2004 Torres Strait Regional Authority (TSRA) figures, its resident population is approximately 340 people. |
