Freshwater wetlands (haors) of Bangladesh are vital for both biodiversity and people. They host tens of thousands of wintering migratory waterbirds and passerines, while providing refuge for globally threatened species such as the Endangered Pallas’s Fish-eagle, the elusive Large-billed Reed Warbler, and the Vulnerable Fishing Cat. At the same time, these wetlands sustain productive fisheries and underpin the livelihoods of local communities.
