Conservation Efforts Lead to Increase in Dugong Population in Tamil Nadu’s Coastal Regions
A survey by the Wildlife Institute of India (WII) and the Forest Department has recorded 270 dugongs along the Tamil Nadu coast, with 158 in Palk Bay and 112 in the Gulf of Mannar. This represents the largest viable dugong population in India. The increase is attributed to the Dugong Recovery Programme and the notification of the Dugong Conservation Reserve in Palk Bay, covering 448 sq. km. The presence of mother-calf pairs indicates active breeding, though researchers note that some individuals may move into deeper waters, affecting count estimates.
