India’s Sacred Groves Nurture Future Forests

Researchers in India’s Western Ghats discovered that sacred groves, forest patches protected due to religious beliefs, are more effective at growing new trees than nearby farmland and villages. A study published in PLOS One examined “giant” trees and found groves hold nearly twice the number of giant-tree species.

These groves also support significantly more young trees, particularly those grown from large seeds dispersed by birds like hornbills, acting as nurseries for the next generation of forest. The research highlights the importance of local knowledge in understanding forest ecosystems, with community members mapping trees and their functions.

While settlements tend to be cultivated orchards, sacred groves function as “ecological time capsules” preserving biodiversity. However, these groves face threats as traditional, simple shrines are replaced with concrete structures and younger generations lose connection to the land. Conservation efforts must therefore focus on both protecting forests and supporting the cultures that maintain them to preserve the region’s ecological network.
