DHAKA: When the harvest begins, Mizanur Rahman gathers a few hundred men and sets out into the mangrove forest along the Bay of Bengal, where for months they climb trees to collect by hand a wild natural honey whose unique properties are only starting to attract global attention. The honey is collected from wild bee colonies deep within the Sundarbans, the world’s largest mangrove reserve spanning parts of India and southwestern Bangladesh. “Honey collection from this forest is mostly done in the Bangladesh part,” Rahman said.
