What are sacred groves and their role in biodiversity conservation?

(N/A) Sacred groves are tracts of forest land that are dedicated to local deities or ancestral spirits and are protected by local communities through religious and cultural beliefs.
These areas are found in many parts of India,such as the Khasi and Jaintia Hills in Meghalaya,the Aravalli Hills of Rajasthan,the Western Ghat regions of Karnataka and Maharashtra,and the Sarguja,Chanda,and Bastar areas of Madhya Pradesh.
Their role in biodiversity conservation is significant because:
$1$. They act as a refuge for many rare,endangered,and endemic species of plants and animals that might have otherwise gone extinct in the surrounding degraded landscapes.
$2$. They help in the preservation of local biodiversity by preventing deforestation and habitat destruction within the grove boundaries.
$3$. They serve as important gene banks for wild relatives of cultivated crops and medicinal plants.
$4$. They maintain ecological balance by protecting watersheds and preventing soil erosion.
