Wilderness Landscape & Natural Heritage
Tanguar Haor Ecologically Critical Area is one of Bangladesh's largest freshwater wetlands, covering approximately 9,727 hectares in the northeastern Sylhet Division. Geographically, it is a bowl-shaped depression or haor that floods during the monsoon and dries out in winter, creating an ideal environment for aquatic plants, fish, and a diverse assemblage of flora and fauna. The haor supports over 140 species of birds, including critically endangered species and numerous migratory birds from Siberia and China, transforming the area into a vibrant hub for birdwatching. It also sustains local communities who rely on fishing, agriculture, and crafting from wetland resources. Declared an Ecologically Critical Area by the Bangladesh government, Tanguar Haor faces pressure from overfishing, habitat degradation, and climate change effects such as altered flooding patterns. Key recreation opportunities focus on guided boat tours, birdwatching, and sustainable cultural experiences with indigenous communities. Notable landmarks include the seasonal islands formed during the dry months and traditional fishing villages that provide a glimpse into local wetland livelihoods. Visitors are drawn by the scenic water vistas, rich birdlife, and the chance to experience an authentic wetland ecosystem rare in South Asia, especially during the peak migratory season from November to February.
