In the Western Ghats of India, small sacred groves maintained by local communities are outperforming nearby village lands at regenerating native tree species, playing a key role in preserving biodiversity and supporting wildlife.
- Sacred groves contain nearly twice the number of giant tree species compared to village lands
- Large trees in groves support seed-dispersing birds like hornbills that help spread native plants
- Preserving traditional culture is vital to protecting these ecological nurseries amid development pressures
What happened
Researchers from the Applied Environmental Research Foundation conducted a detailed study in Vanzole, a northern village of the Western Ghats mountain range. They mapped 82 giant trees across 20 species, identifying those over one meter in trunk diameter. They found sacred groves maintained by communities held nearly twice the diversity of these large native trees compared to surrounding village lands.
The groves function as ecological refuges harboring species absent from agricultural or inhabited areas nearby. Trees common to village areas were fruit-bearing species like mango and jackfruit, while groves contained medicinal and native trees such as baheda, illustrating how groves serve as living time capsules of the region’s original forest biodiversity.
Why it feels good
Giant trees within the groves play a crucial ecological role, acting as key supports for hornbills and other large fruit-eating birds. These birds disperse the seeds of native trees over wide areas, facilitating natural regeneration and sustaining plant diversity. The study revealed a remarkable difference in sapling growth beneath grove trees versus village trees, with 77% of grove trees hosting seedlings of the strychnine tree compared to just 5% in villages.
These groves not only protect species but also serve as stepping stones in fragmented landscapes, helping maintain vital wildlife corridors. Sightings of endangered animals like the Royal Bengal tiger and black leopard near protected groves highlight their broader importance in sustaining complex ecosystems.
What to enjoy or watch next
As India and the world seek solutions to climate change and biodiversity loss, the sacred grove model offers an inspiring example of how tradition and nature conservation can align. However, some groves face threats from modernization, including temple construction that destroys understory vegetation and root zones vital for regeneration.
Conservationists emphasize that protecting these groves requires supporting the cultural customs that have historically guarded them. Observers and nature lovers should appreciate the unique balance these groves provide and watch for efforts to maintain and expand such sacred natural sites as living forests for future generations.
