Today marks a historic achievement in wildlife conservation as the first-ever Ganges River Dolphin (Platanista gangetica) has been tagged in Assam. This initiative, which is a significant advancement of Project Dolphin, was implemented by the Ministry of Environment, Forest and Climate Change (MoEFCC) in collaboration with the Wildlife Institute of India (WII), the Assam Forest Department, and Aaranyak, with funding from the National CAMPA Authority.
Background of the Initiative
The Ganges River Dolphin, India’s National Aquatic Animal, has faced significant challenges due to limited information about its habitat needs, movement patterns, and home-range. To address these gaps, the tagging initiative was launched to study the dolphin’s seasonal and migratory patterns, range, distribution, and habitat utilization, especially in fragmented or disturbed river systems.
The first dolphin tagged was a healthy male, which was released after being tagged with utmost veterinary care. This is the first-ever satellite tagging of the species, not only in India but globally.
Key Stakeholders and Contributions
- MoEFCC: Provided leadership and funding for the project.
- Wildlife Institute of India (WII): Led the tagging initiative and conducted research.
- Assam Forest Department: Collaborated in the fieldwork and implementation.
- Aaranyak: Partnered in the conservation efforts.
- National CAMPA Authority: Funded the project to ensure its success.
Union Minister for Environment, Forest and Climate Change, Shri Bhupender Yadav, expressed his joy on social media, highlighting the historic nature of the project and its importance for the conservation of the Ganges River Dolphin.
Ecological Importance of the Ganges River Dolphin
The Ganges River Dolphin is unique in its ecology, being nearly blind and relying on echolocation for navigation and hunting. Approximately 90% of the species’ population resides in India, with historical distribution across the Ganga-Brahmaputra-Meghna and Karnaphuli river systems. However, its population has drastically declined over the past century due to various ecological threats.
The dolphin’s elusive behavior, surfacing for only 5-30 seconds at a time, makes it challenging to study and understand its ecological needs. This knowledge gap has hindered effective conservation efforts.
Project Dolphin and Long-Term Conservation
Under the umbrella of Project Dolphin, the MoEFCC, through National CAMPA Authority, has funded comprehensive research to develop a conservation action plan and address the existing knowledge gaps. The Ganges River Dolphin, being an apex predator, plays a crucial role in maintaining the health of the river ecosystem. Ensuring the well-being of this species will help sustain the entire river ecosystem.
Shri Virendra R. Tiwari, Director of WII, emphasized that the tagging of the river dolphins would contribute to evidence-based conservation strategies, which are urgently needed for the species.
Technological Advancements in Tagging
The success of this initiative was made possible by advancements in satellite tagging technology. The lightweight tags emit signals compatible with Argos satellite systems, even with limited surfacing time. These tags are designed to minimize interference with the dolphin’s natural movement.
Future Plans and Expansion
Plans are underway to extend the tagging initiative to other states where Ganges River Dolphins are found. This will help build a comprehensive understanding of their population dynamics and habitat requirements, furthering the goal of long-term conservation for the species.
Importance of Conservation
Project investigator Dr. Vishnupriya Kolipakam highlighted the significance of this initiative in understanding the ecological needs of river dolphins. This research will not only help conserve critical habitats within vast river ecosystems but also support the livelihoods of thousands of people who depend on these resources.
Conclusion
This milestone in the conservation of the Ganges River Dolphin sets a new benchmark in the protection of endangered species and underscores India’s unwavering commitment to wildlife conservation. The tagging initiative is a monumental step forward in understanding and preserving one of India’s most iconic aquatic species.
