Along the coast of Kerala and in the Western Ghats, patches of old forest survive between rice paddies and rubber plantations. Many are kavu, sacred groves dedicated to a deity, often a serpent god or a goddess, and protected by the belief that cutting a tree there brings misfortune. Estimates for Kerala range from a few hundred to more than a thousand groves; across India there are tens of thousands. They are a textbook case of cultural ecology, where a religious norm does the work of a conservation law.
What lives in a grove
Botanists have recorded rare and endemic species in Kerala’s groves that have disappeared from the surrounding landscape, including medicinal plants and old-growth trees of the lowland evergreen forest that once covered the coast. The groves also protect ponds and springs, which is why villagers value them in dry months. Some groves are only a few trees; the largest cover several hectares and function as small nature reserves.
Why they are shrinking
Studies since the 1990s report steady loss. Land is divided among heirs and sold, temples are rebuilt in concrete and the surrounding forest is cleared for the building, and younger generations no longer share the taboos. Where a grove is managed by a family rather than a community it tends to vanish faster. The Kerala Forest Department and the state’s biodiversity board have run programmes to document and fence groves, and some have been declared community reserves under the 2002 Wildlife Protection Act amendment.
What South India teaches
The groves show both the strength and the limit of belief as a conservation tool. Strength: a rule that nobody enforces in court held for centuries. Limit: it holds only as long as the culture that made it. Cultural ecologists therefore argue for linking traditional rules to modern ones, recognising groves in land records, paying communities for protection, and teaching the ecology behind the taboo. Similar cases exist in Ghana, Ethiopia, Japan and among Indigenous peoples in the Americas.
