Sacred and traditional beliefs plays an significant role in conservation of biodiversity. Based on spiritual and cultural values,local communities in many parts of the world have conserved sacred forests or groves. This research studied 3 Sacred Groves (Daikho) in Dima Hasao that are protected by the Dimasa community through their religious beliefs. 10 quadrats were taken from each sacred grove, i.e. (1x1)m for herbs, (5x5)m for shrubs was laid down randomly for vegetation analysis. Floristic analysis revealed that a total of 44 species belonging to 42 genera and 27 families were observed in the Sacred Grove. Total numbers of herb, shrub, climbers and fern species encountered in each Sacred Grove were 29, 10 and 6 respectively. The Simpson value index for dominance and Shannon Weiner Index of herbs and shrubs showed highest species diversity in site 1 and site 2. The data collected include information regarding the Sacred Groves and their associate deities, nearest human habitation and their floral diversity. A questionnaire was conducted in the nearby villages namely Nabdidaolaguphu (Site 1), Gerem (Site 2) and Longma (Site 3). Different deities are worshipped in different Daikho and each Daikho was named after the deities dwelling in respective Sacred Groves. Many taboos help in managing the natural resource of the Sacred Grove. But people’s change in their attitude, human impact and erosion of religious beliefs have degraded Sacred Groves year after year. So, supporting traditional culture, existing local community management of resources and creating awareness among the communities is highly recommended.
