The objective of this study is to establish observation methodology for the monitoring both of seagrass habitat and dugongs’ feeding behavior. Our study needs to be conducted in tidal flat’s seagrass beds. Although the seagrass beds in the tidal flat exist near the place of human activities and dugongs can feed there only at around high tide, it have been difficult to observe the feeding behavior of dugong, even though a lot of their grazing trails could be observed.
