| Sea turtles are considered of the critically endangered (CR)
reptiles in the world. Several threaten factors affect the survival and
regeneration of these species. Therefore, to support their survival,
identification and management of factors which affect reptiles
nesting are inevitable. Sea turtles spend one of the critical stages of
their life, hatchery period, at the beaches, so identification of nesting
sites and the factors influenced their hatching plays an important
role for conserving these endangered species. Previous studies
showed that slope, grain size, sediment temperature, shore
vegetation and some of human manipulation is effective in nest
location of these sea turtles. In this study slope, in the nest locations
of Eretmochelys imbricata in Shib-deraz area (Shib-deraz habitat
and shib- pavi) of the south Qeshm Island was investigated. This
study was done in nesting season in 1391 along the 1/5 km from the
sandy beach area. Suntu inclinometer was employed to measure the
nest slopes, 32 nest locations from high water mark to the nests.
Results showed that 37.34 % of sea turtles choose the slope class of
2-4 degree for the nest investment in this area. |
