Researcher Andrew Dunstan and his colleagues from the Queensland Government’s Department of Environment and Science had not expected the sight that met them when they sent a drone up above the Raine Island in the Great Barrier Reef.
64.000 skjoldskildpadder skvulpede around in the sea around the island, and it was many more than they had anticipated.
It writes CNN.
Skjoldskildpadden is an endangered species, and scientists have long followed the population size, but until now they have spoken them from a boat, and the drone-the result shows a completely different picture than in the past.
– We have underestimated it very much. We found 1,73 times as many turtles with the drone, than we did, if we compare with the observed numbers, tells Andrew Dunstan to CNN, with reference to tidiligere spoke from a boat.

Hence, should the previous data for the population also be taken up for revision now.

Skjoldskildpadderne is threatened by both hunting, æggehøst and fishnet in the sea.
– We became aware that, although there is a large amount of turtles, so function their reproduction is not particularly good, says Andrew Duncan to CNN.
the research Team has noticed that the turtles often fall out from the rocks and becomes trapped in the sun, and their nests are often destroyed by floods.
