The haor basin contains around 46 small villages that exist within the wetland territory.
It is home to the rare Pallas's Fish Eagle and the endangered Greater Adjutant stork.
Over 135 species of aquatic plants have been identified within the ecosystem.
The water depth varies from less than 1 meter in the dry season to over 10 meters during the peak monsoon.
It is internationally recognized as a Ramsar Wetland of International Importance.
The local 'Hijal' and 'Koroch' trees are uniquely adapted to withstand prolonged submersion.
The wetland acts as a natural fish nursery, replenishing stocks for the surrounding river systems.
Tanguar Haor is a unique freshwater wetland ecosystem covering approximately 100 square kilometers in the Sunamganj district of Bangladesh. It is designated as a Ramsar Site, recognizing its global importance as a wetland habitat for diverse flora and fauna. The area transforms seasonally, expanding into a vast inland sea during the monsoon and receding into smaller ponds or 'kanda' during the dry season. It serves as a critical breeding ground for over 200 species of fish and acts as a major wintering site for migratory birds traveling from the Himalayas. The landscape is dotted with indigenous villages and distinct swamp forests, primarily comprised of Hijal and Koroch trees. Local communities rely on the haor for traditional fishing and agriculture, integrated into the site's management framework. The environment is characterized by its shallow basin structure, which fluctuates significantly in water depth. It is one of the largest wetlands in the country, playing a vital role in local water regulation and biodiversity conservation.

Hire a local boatman who knows the intricate waterways to navigate the submerged vegetation safely.
Bring high-quality binoculars for birdwatching, as many species remain at a distance from boats.
Pack biodegradable sunscreen and mosquito repellent, as open water exposure and insects are common.
Avoid traveling during peak monsoon storms when water conditions become hazardous for small boats.
Access is restricted during the deep monsoon months when storms are frequent; best visited when water levels are manageable.
Respect the local fishing communities; do not disturb nests or vegetation; keep noise levels low to avoid scaring wildlife.
