Abstract

The tutle nesting beach in Subdistrict of Paloh is a turtle habitat of nesting and breeding process. The hot spot area on Sebubus Beach has a total length of ± 19 km. The physical characteristics of coastal morphology and structure of the natural vegetation that make up the area, beach with a slope greater 30% and shade of vegetation affect the nest moisture. The research was conducted in August 2016 to examine the physical characteristics of the beach in relation to the structure and vegetative composition, with the method of observation and plot lines. The plot line method is used to calculate the significance of vegetation at every point where turtles lay eggs. The slope of the turtle nesting beach is 4% - 9%, with temperatures of 25,9°C – 29,81°C. The dominant species on each segment on the segment S. Belacan – Tj.
