A helicopter was used to fly over the seagrass beds in the area during both high tide and low tide. The largest number of Dugongs sightel during high tide was 14, and 11 at low tide. These sightings took place at either Young Lum cape or around Talibong island. Two calves were also sighted during the survey.
