Lying close to the Himalayas, the Sylhet area has extensive natural depressed lands locally called ‘haors’ (pronounced ‘howers’, wetlands). During the winter season they are home to huge flocks of wild fowl. Outstanding species include the rare Baer’s pochard and Pallas’ Fish Eagle, along with a great number of ducks . Other important habitats are the remaining fragments of evergreen and teak forests, especially along the Indian border near the Srimongal area.
