Guinea-Bissau's Bijagós Archipelago Supports Rich Shorebird and Sea Turtle Populations

The Bijagós archipelago off the coast of Guinea-Bissau boasts expansive mudflats, sandy beaches, and dense mangrove forests that form a vital coastal ecosystem. These habitats provide essential feeding, nesting, and roosting sites for a wide array of migratory shorebirds, including species that travel along the West African flyway. In addition, the islands support large populations of sea turtles, offering safe nesting beaches and abundant foraging grounds.

Ecologists note that the combination of tidal flats and mangrove corridors creates a nutrient-rich environment that supports high productivity. The mudflats act as natural filters, trapping sediments and pollutants, while the mangroves stabilize shorelines and provide nursery habitats for juvenile fish and crustaceans that shorebirds rely on for food. The presence of sea turtles, many of which are listed as endangered, underscores the archipelago’s importance as a critical breeding and feeding ground in the Atlantic.

Conservation groups have highlighted the Bijagós as a priority area for marine biodiversity protection. Ongoing monitoring and community-based management initiatives aim to safeguard these habitats from overfishing, coastal development, and climate‑related sea‑level rise. Maintaining the integrity of the mudflats, beaches, and mangroves is essential for preserving the migratory shorebird populations and the reproductive success of the sea turtles that depend on them.
