Bijagos Archipelago lies off the coast of Guinea-Bissau near Bissau, where channels, mangroves and mudflats shape the seascape. It is an archipelago of 88 islands and one of the clearest examples of a deltaic island system on Africa’s Atlantic coast.
Delta waters and island chains
The archipelago sits opposite the mouth of the Rio Geba and spreads across marine and intertidal terrain. Its landscape includes mudflats, mangroves, palm groves and coastal woodland savannah, with the islands low enough for tides to reshape the edges every day.coastal and marine ecosystems
The site is recognised in the UNESCO Man and the Biosphere programme as Bolama-Bijagos, a reserve first nominated in 1996.Biosphere Reserve That designation fits a place where sea, estuary and island land remain closely interwoven.
Wildlife shaped by tides
Birdlife is one of the archipelago’s defining features, with migratory shorebirds using the mudflats and shallow waters in large numbers. Sea turtles also nest here, while manatees, dolphins and crocodiles belong to the wider fauna of the islands and channels.mangrove and mudflat habitat
The ecology is not confined to the shoreline. Forest, savannah, mangrove and shallow sea sit close together, and the result is a varied island landscape rather than a single habitat type.
Protected islands and local settlement
Several protected areas fall within the archipelago, including Orango Islands National Park and João Vieira and Poilão Marine National Park. The islands also have long-standing settlement patterns, with some inhabited permanently and others seasonally.
Bolama-Bijagos reflects both natural history and human use. Its recorded status as a biosphere reserve and its later UNESCO World Heritage inscription place the archipelago among Guinea-Bissau’s most important coastal landscapes.World Heritage List
