After laying eggs on a abandoned Thai seashore, a inexperienced sea turtle dives again into the turquoise-coloured waters of the Andaman Sea — a welcome sight for biologists who say the absence of vacationers spurred the marine animal’s return.
The turtle’s nesting was noticed in November by scientists. In about two months, the 100 eggs will hatch and infants will slide in the direction of the ocean, guided by the moonlight.
Pre-pandemic, tens of millions of vacationers thronged to the white sand seashores of southern Thailand, ferried to the islands by tour boats which dissuaded the skittish creatures from venturing ashore.
But with virtually 20 months of covid journey restrictions in place, a number of totally different species of sea turtles have returned to nesting round Phuket, an ultra-popular seashore vacation spot earlier than the pandemic.
Between October 2020 and February 2021, 18 nests of leatherback turtles — which may develop up to 400 kilograms as an grownup and are the biggest species of sea turtles — had been present in Phuket.

“Their nesting has improved in the last two years thanks to the absence of tourists, noise and light pollution,” Kongkiat Kittiwatanawong, director of the Phuket Marine Biological Center, informed AFP.
“We had never seen such a number in 20 years.”
Although possibilities of survival are very low — about one egg hatched out of 1,000 will attain maturity — Kongkiat stated the rise in nesting is a optimistic signal for efforts to protect endangered species.
A nest of the olive ridley sea turtle was additionally noticed — the primary time in 20 years. Other species that dwell within the heat waters round Thailand embrace leatherback, hawksbill, inexperienced and loggerhead turtles.
No long-term reprieve –
But as Thailand tentatively begins to reopen its doorways to absolutely vaccinated worldwide vacationers, scientists have tempered their optimism.
“The pandemic may offer sea turtles a welcome break,” Thon Thamrongnawasawat from Kasetsart University in Bangkok stated.
“But they live long and are a highly migratory species. Without effective policies to protect them, we can’t expect many long-term benefits to population recovery.”
In Thailand — as in lots of different international locations — the marine animal’s future is threatened by international warming, which harms coral reefs and will increase the temperature of the waters.
The hotter circumstances might in flip disrupt turtle species’ populations: research have proven that hotter sands the place they nest lead to extra feminine hatchlings relative to males.
Pollution can be an issue. At the second, plastic and discarded fishing traces and nets stay the first reason for illness and loss of life.
“In 56 per cent of the cases, the turtles that are brought to us have ingested marine waste or become trapped in it,” stated Dr Patcharaporn Kaewong from the Phuket Marine Biological Center.
Currently, 58 turtles are being handled there. Some want operations, amputation or prosthetics earlier than they’re launched again into the wild.
Tracking the turtles
At the second, scientists and native authorities are on excessive alert for nesting season, which runs till February.
After a feminine turtle lays a nest, the authorities will act shortly — both shifting them to a protected place if they’re too shut to the water or surrounding it with bamboo fences and safety cameras.
“After hatching, we take care of the weak turtles until they are strong enough to go to the sea,” Patcharaporn stated.
She added that educating the general public about conservation was additionally necessary.
Up till just a few a long time in the past, consuming turtle eggs was a typical customized in Thailand, however gathering them was banned by the Thai authorities in 1982.
Illegally possessing or promoting leatherback turtle eggs is now punishable by three to 15 years in jail, and carries fines of up to $50,000.
Some marine safety NGOs are additionally financially rewarding locals who report a nest, whereas expertise — like microchipping a turtle — additionally performs an element in long-term monitoring.
“Thanks to satellite tracking, we have observed that they can migrate much further than we thought,” Kongkiat stated, including that some have gone so far as Australia.
