We used binocular to see along the shore from boat. It's another way to find the turtle tracks. (Photo Below: The conservation rangers Bj,Q, and Rofiq who was mapping out the survey)
We made two teams to find turtle nests at different shores. We then recorded the turtle tracks we found, how many nests there are and how the condition of each nest is. Usually the cause why there are no eggs within the nests is known from the condition of the nests which is appeared.
