Olive Ridley Turtle Hatchlings Released to Sea

img
Seven species of turtles are found in the warm waters of seas in the temperate-tropical zone. Of these five species make a visit to the Indian coast annually for laying of eggs and rearing. They nest all along the Indian coastline of Bay of Bengal in the east and Arabian sea in the west. Of these Olive Ridley Turtles (Lepidochelys olivacea) outnumber all others in numbers in visiting the Indian shore. Eastern coast is having larger nesting areas. Gahirmatha and Rishikulya in Odisha are globally recognized massive nesting sites. When it comes to the western coast of India, massive nesting sites are not reported. Only few sites are known where egg laying is very sporadic and moderate. In Kerala, only very few turtles are making the annual trip for laying of eggs. Neeleswaram beach in Kasaragod, Kozhavippalam in Kozhikkode, Chavakkad beach in Guruvayur in Thrissur, Kuzhippilli and Cherai beaches in Ernakulam, Thottappali beach in Alappuzha, Chiillikkal, Pozhikkara and Mukkam beaches in Kollam and Vizhinjam beach in Thiruvananthapuram are the major landing sites for these turtles in Kerala. As per an established pattern, northern Kerala shores receive the highest number of turtles, while their number decreases as one travels to the south. Visit of Olive Ridley turtles in Kollam is sporadic. They have been laying eggs on the shores of Chillikkal, Pozhikkara and Mukkam beaches in Paravur coast, notably because these are the only gaps without a seawall erected as a measure against sea erosion. These turtles crawl freely to the shore under the cover of darkness, dig pits in the sand some of which are large as to hold up to 100 of its eggs. In course of nearly two months, when the eggs hatch, hatchlings are led back to the sea by themselves as if by instinct. Parental care is sparsely observed in these species of turtles.There have been large scale losses of these eggs at the hands of miscreants who steal them and sell for a paltry sum. It is also not uncommon that adult turtles which may get entrapped in fishing nets are often slaughtered for its flesh which fetches higher amounts in the black market. While the major nesting sites of Olive Ridley turtles are well identified and managed , sites where turtles make only sporadic or erratic visits are not seriously managed, not to speak about its protection. Owing to the sporadic nature finding exact position of their nesting sites and arranging for its protection poses serious challenges in southern Kerala. Consequently conservation activities in most sites in southern Kerala is negligible. Protecting the turtles and their eggs are one of the most efficient way of conserving them. The Thiruvananthapuram-based N.G.O working in the field of nature conservation and environment protection, Travancore Nature History Society (T.N.H.S), has seized of this situation in 2020 and initiated a community-based conservation effort in the sporadic nesting sites of turtles with the active co-operation and help of the Department of Forests and Wildlife of the Government of Kerala. It has conceived a novel project ‘Punarjani’ and selected Chillikkal beach near Paravur, Kollam district to implement it at the first instance. It was formally launched on January 23, 2020 at Chillikkal beach at a brief function presided over by Shri S Heeralal, Asst Conservator of Forests (ACF), Social Forestry, Kollam. But, to the disgust of T.N.H.S and Social Forestry wing, Kollam, Olive Ridley Turtles did not choose Chillikkal beach for egg laying.
