Once widespread across the Gulf of Mannar, Palk Bay, Gulf of Kutch and the Andaman & Nicobar Islands, dugongs in India dwindled to just a few hundred due to poaching, by-catch, habitat loss and pollution. Their slow rate of reproduction compounded the crisis. In recent years, however, targeted conservation initiatives have offered cautious optimism.
The landmark step was the notification of the Dugong Conservation Reserve in Palk Bay (2022) under the Wildlife (Protection) Act, protecting over 12,000 hectares of seagrass meadows. Tamil Nadu’s proactive stewardship, aided by the Wildlife Institute of India (WII) and community engagement, has reduced poaching and encouraged fishers to release by-caught dugongs. The International Union for Conservation of Nature (IUCN) has recognised this reserve as a global exemplar, praising its ecological value and innovative restoration techniques. Current WII surveys suggest a fragile but encouraging population of over 200 dugongs in the region.
Fun Facts About Dugongs
– Dugongs are the only strictly herbivorous marine mammals, feeding exclusively on seagrass.
– They are thought to have inspired ancient mermaid myths when sailors glimpsed them from afar.
– With lifespans of up to 70 years, females give birth to just one calf every 3–7 years, making recovery painfully slow.
– Often called “sea cows”, they are gentle and shy, preferring slow grazing to acrobatics like dolphins or whales.
Gains and Innovations
- Technology use: drones, acoustic and satellite mapping of seagrass beds.
- Community participation: fisher involvement in reducing by-catch.
- International recognition: IUCN endorsement adds legitimacy and scope for collaboration.
Continuing Challenges
- Threats from mechanised fishing, dredging, port construction and agricultural-industrial pollution.
- By-catch deaths persist despite awareness efforts.
- Climate change risks: warming seas, acidification, and storms damaging seagrass beds.
- Populations in Gujarat and the Andamans remain smaller and less protected.
- Need for India–Sri Lanka cooperation across the Palk Strait for shared protection.
- Funding remains inconsistent; dugongs require long-term, multi-decade investments due to slow reproduction.
Broader Lessons
- Integrated marine conservation needs intact ecosystems, not isolated species focus.
- Community partnerships with fishers create strong local constituencies for conservation.
- Blending traditional knowledge with modern tools (drones, echosounders) enhances ecological management.
- International recognition can amplify domestic conservation, enabling knowledge exchange and legitimacy.
Conclusion
India’s dugong conservation journey demonstrates that determined local action, technology, and community partnership can reverse near-extinction trends. Yet without regional cooperation, sustained funding and protection against climate and developmental threats, gains will remain fragile. The dugong story is a template for broader marine conservation in India — combining science, tradition, and community ownership.
