PHANGNGA: Marine conservation officials have used thermal imaging equipment mounted on a drone to capture video of a leatherback sea turtle, the world’s largest turtle species, coming to shore to lay eggs.

Leatherback sea turtles are classified as vulnerable on the International Union of Conservation of Nature (IUCN) Red List, with populations declining due to habitat loss, poaching, and plastic pollution.

The turtle spotted last week in the southern province of Phangnga had found its way to shore and dug a nest in the sand to lay her eggs. The eggs will incubate for the next 55 to 60 days before hatching, according to the website of the Department of Marine and Coastal Resources.

The department said a thermal drone was able to record more information than labour-intensive human patrolling techniques, as its sensors could detect the body heat of warm-blooded animals — or more specifically the thermal differences between animals and their surrounding environment — despite the darkness.

The technology was helpful in preventing noise and light from disturbing the turtles while nesting, it said.
