Saving the Olive Ridleys, one shore at a time

The Olive Ridley sea turtle or the Pacific Ridley sea turtle is considered to be the smallest and the most abundant of all sea turtles in the world. Yet in a single generation (20 years) their population has declined drastically from more than 10 million in the pre-mass extinction era to about 800,000 as per a recent count.

In the midst of this gloom there is still hope. A tiny village in Maharashtra, which doesn’t even have 5 full sentences as description on Wikipedia, has been working with local NGOs for over a decade now towards conservation of these endangered species.

Velas is a small village in the Ratnagiri district of Maharashtra and is about an 8 hour drive from Mumbai. A decade ago the villagers were concerned about the Olive Ridleys to be able to steal the eggs once laid for consumption or for sale and to hunt the female turtles when they came on shore to breed for the meat or again for sale. However, that was before they joined hands with Sayhadri Nisarg Mitra, an organization which works with these same villagers now towards massive conservation efforts.

Over the past decade, not only have they successfully managed to change the age old habits by making villagers protect the eggs instead of stealing them, they have also helped the residents tap into an additional source of income and put this nondescript village on the tourist map for the turtle breeding months. And this is without any institutional support or a conducive ecosystem for wildlife conservation.

Come November, the female turtles swim in hordes to these shores to lay their eggs in batches of 3 to 4 where each batch consists of 100-150 eggs. It might seem a lot, however the survival rate of these turtles is only 1 in 1000. Thus, only a handful of the turtles hatched from these eggs reach adulthood and the females, it is said return to the same shores to lay eggs where they were born; thus, travelling distances across several hundreds of miles to complete the circle of life.

The eggs once laid, are pretty much left on their own to figure out their way in this cruel world. The members of Sayhadri Nisarg Mitra along with volunteers from the village transfer these batches of eggs to hatcheries to protect them from dogs and other animals. These hatcheries, though are man-made, but have to replicate the conditions created by the female turtle while she laid them. This means, the depth, the temperature of the sand and the moisture needs to be replicated. In fact the difference in these factors not only impacts the rate of the eggs hatching, but also determines the gender of the new born turtles.

After an incubation period of up to 3 months, the eggs hatch. And there can be no better words to describe the scene, other than it is what a miracle looks like. In this crazy race of conquering the world, we tend to overlook the intricate designs nature has, and how everything takes care of itself, as long as we do not poke our annoying human noses. These little hatchlings, with no motherly support around, barely with any sense of sight, only rely on their intuition as they move together towards the sea using their miniscule flippers. Majority of them do not survive even the first few kilometres into their journey of life. Several die over the years if not due to natural causes, then due to human greed. 

For the few that do survive, return to their shore of birth to start a new cycle.

On an average a female turtle reaches maturity and starts laying eggs in 20 years. It’s only a couple of years of wait to see if the efforts of this tiny village and Sayhadri Nisarg Mitra have been successful. And if out of the batch of turtles they released more than a decade ago, return to pay them a visit.
