Sacred groves are the forest patches around the places of worship which are held in high esteem by tribal communities due to their religious sanctity. They represent islands of pristine forests. Such groves are found in Khasi and Jaintia hills in Meghalayas, Aravalli hills of Rajasthan, Western Ghat regions of Karnataka and Maharashtra. In the sacred groves, not a single branch is allowed to be cut. As a result, many endemic species which are rare or became extinct elsewhere can flourish here. Thus sacred groves help in biodiversity conservation.
