New Delhi: In a historic milestone for marine conservation, the International Union for Conservation of Nature (IUCN) has officially recognized India’s inaugural Dugong Conservation Reserve in Palk Bay during the IUCN World Conservation Congress 2025 in Abu Dhabi. This prestigious endorsement celebrates Tamil Nadu’s pioneering efforts to protect the vulnerable dugong (Dugong dugon), fondly known as the sea cow, and positions India as a global leader in marine biodiversity preservation. The resolution highlights a scalable model for safeguarding dugongs and their habitats across the Indian Ocean and similar ecosystems worldwide.

IUCN Motion: A Unified Global Endorsement
Proposed by the Omcar Foundation, the motion garnered overwhelming support through electronic voting at the Congress. An impressive 98% of governments and state agencies, alongside 94.8% of NGOs, research institutions, and other organizations, voted in favor. This near-unanimous backing underscores the international community’s appreciation for India’s innovative conservation framework. The resolution not only honors the Palk Bay reserve but also calls for its replication in other regions where dugongs face existential threats, emphasizing the integration of community-led and scientifically robust strategies.
The IUCN advocates for collaboration with the Indian government, Tamil Nadu authorities, and local organizations to strengthen monitoring, promote sustainable fisheries, and share expertise with global dugong conservation programs. The motion addresses critical challenges, including habitat degradation, destructive fishing practices, and climate change impacts, which threaten dugong populations and the ecological balance of coastal ecosystems.
The Dugong Conservation Reserve: A Haven for Marine Ecosystems
Launched on September 21, 2022, under the Wildlife Protection Act, 1972, by the Tamil Nadu government, the Dugong Conservation Reserve spans 448.34 square kilometers in northern Palk Bay, encompassing coastal waters of Thanjavur and Pudukkottai districts. The region is home to over 12,250 hectares of seagrass meadows, which serve as critical feeding grounds for dugongs and nurture a diverse array of marine species. These seagrass beds also play a vital role in carbon sequestration, contributing to climate change mitigation and enhancing the reserve’s ecological significance.
As India’s first dedicated dugong sanctuary, the reserve strengthens Palk Bay’s status as the nation’s primary stronghold for the species. Its establishment reflects Tamil Nadu’s commitment to preserving marine biodiversity and fostering sustainable coastal ecosystems.
Pioneering Restoration and Community Synergy
The IUCN Congress praised the reserve’s innovative restoration techniques, notably the use of bamboo and coconut rope frames to rehabilitate degraded seagrass meadows. This approach combines cutting-edge science with active community participation, creating a sustainable model for habitat restoration. By engaging local fishers and residents, the initiative builds trust and ensures long-term conservation success.
The resolution highlighted pressing threats to dugongs, including habitat loss, unsustainable fishing practices, and climate change. It urged the adoption of community-driven strategies to promote sustainable marine resource use. The IUCN called for its members to partner with India’s central and state governments, as well as local organizations, to enhance monitoring systems, develop eco-friendly fisheries, and facilitate knowledge exchange with international conservation programs.
Tamil Nadu’s Conservation Successes
Tamil Nadu’s on-the-ground efforts have delivered measurable outcomes. Between the 2021-22 financial year and September 2025, 16 dugongs were rescued and released in the Thanjavur and Pudukkottai forest divisions, showcasing effective intervention mechanisms. To foster cooperation with fishing communities, the state introduced a compensation and reward system. A total of 1.16 lakh rupees was disbursed for fishing net damages caused by dugong entanglements, with an additional 1.59 lakh rupees awarded for prompt reporting of such incidents. In total, 2.75 lakh rupees have been distributed to 62 fishers, with Thanjavur accounting for 51 beneficiaries.
This incentive system has transformed community dynamics. “The compensation and reward mechanism has created trust among fishers, who now report entanglements promptly, enabling safe dugong releases,” said Balaji Vedharajan, director of the Omcar Foundation. Supriya Sahu, Additional Chief Secretary of Tamil Nadu’s Environment, Forests, and Climate Change Department, described the IUCN recognition as a validation of the state’s leadership in marine conservation across South Asia. Yash Veer Bhatnagar, IUCN’s India representative, noted early signs of species recovery, crediting these comprehensive efforts.
On September 25, 2025, Tamil Nadu Chief Minister M.K. Stalin took to X to celebrate the IUCN recognition, commending the Tamil Nadu Forest Department, Omcar Foundation, and all stakeholders for their dedication. His public acknowledgment highlights the state’s unified commitment to marine protection.
The Dugong: A Gentle Giant Under Threat
The dugong, scientifically classified as Dugong dugon within the Dugongidae family, is the world’s only strictly marine herbivorous mammal. Growing to over 300 kilograms and measuring 3.0 to 3.5 meters in length, dugongs inhabit calm, nutrient-rich shallow waters within 10 meters of depth, typically in groups of 5 to 7 among seagrass beds. Each dugong consumes 30 to 40 kilograms of seagrass daily, underscoring their reliance on healthy meadows.
Globally, dugongs inhabit tropical and subtropical waters across 37 countries, from East Africa to Vanuatu. In India, they are found in Palk Bay (with the highest population), the Gulf of Mannar, the Gulf of Kutch, and the Andaman and Nicobar Islands. Populations off the coasts of Odisha, West Bengal, and Andhra Pradesh went extinct two centuries ago. Current estimates suggest a national population of approximately 200 to 250 dugongs, with Palk Bay as the primary refuge.
Dugongs face severe threats, including habitat degradation, hunting, unintentional captures in fishing gear, destructive fishing practices, and climate change. Their conservation status is critical: listed as Vulnerable on the IUCN Red List, included in Schedule I of the Wild Life (Protection) Act, 1972, and protected under Appendix I of CITES.
A Global Blueprint for Marine Conservation
The IUCN’s recognition establishes the Palk Bay reserve as a global model for marine biodiversity conservation. Often called “farmers of the sea,” dugongs maintain seagrass ecosystems, which support fisheries and coastal resilience. The resolution’s call for international partnerships and replication of India’s approach offers hope for at-risk dugong populations worldwide.
The Congress emphasized the need for stronger community-led strategies, sustainable fisheries, and cross-border collaboration. By integrating local knowledge with scientific innovation, India’s model addresses both ecological and socio-economic challenges, providing a framework for regions facing similar threats.
Future Horizons: Building on Success
The IUCN’s endorsement marks both a celebration of achievements and a call to action. Enhanced monitoring, sustainable practices, and international cooperation will be pivotal to ensuring the dugong’s survival. As Tamil Nadu leads the way, the reserve’s success inspires hope for marine conservation globally, reinforcing India’s role as a steward of oceanic biodiversity.
