The tidal forest Sundarbans is mostly ecologically important in India, enriched with diversified flora and fauna. Among flora some plants are specific for the honey bee Apis dorsata. Honey production by bees continued in the Sundarbans forest generally from March to June. Honey collection from natural habitat of the bees is a traditional occupation of some forest dwellers, they are locally known as ‘Mowals’. Mowals use their indigenous knowledge and rituals during the honey collection journey called ‘Mahal’. The objectives of the study are to explore the indigenous knowledge used by Mowals related to the journey Mahal and to find out the relation between explored Indigenous knowledge and sustainable development. The qualitative study used face-to-face interview and focus group discussion for data collection, data analysis followed by thematic analysis method. From data analysis that indigenous way of honey collection by Mowals is a good twinning strategy to protect biodiversity without any harmful effect on environment and sustainability with its indigenous cultural practices. Mowals not only ensure the environmental sustainability but also prompts and facilitates social, cultural, and economic development. But till now Mowals of Sundarbans are deprived with non-indigenous identity by the Government and the culture is abolished rapidly. Government should take necessary steps for conserving the indigenous way of honey collection giving needful protection to the Mowals.
