How do you count 64,000 green sea turtles? This beautiful endeavor took place in December of 2019, on Raine Island, on the outer edge of the Great Barrier Reef in Queensland, Australia. Everything is explained in a fascinating video posted by the Queensland Government on Twitter. They’ve shown green sea turtles nesting just off the coast of Raine Island. Before, they were using boats to count turtles in the water. Today it’s much easier, by using drones that give a much wider shot. Also shown in the video you can see how the diligent team works the entire night to mark turtles onshore with white paint that washes off in a few days. 64,000 green sea turtles were either nesting in their rookery or waiting to come ashore to lay eggs. The drone footage was analyzed frame by frame in a laboratory, making this approach much more precise than the previous. The population count was a part of the Raine Islands recovery project. Endangered turtles are suffering from hunting, poaching, boat strikes, fishermen’s nets, pollution, and habitat destruction. For more information please visit websites below.
The largest colony of green sea turtles in the world
Location: Raine Island, on the outer edge of the Great Barrier Reef in Queensland, Australia.
Population count took place in December of 2019.
Scientists counted 64,000 (Endangered) Green Sea Turtles.
The hard-working team needed an entire night to mark 2000 turtles with washable paint
Unmarked turtles were counted from drone footages
This approach is much more efficient and precise than the previous one where they would count turtles by looking at them from boats.
