Nest site fidelity and nest site selection of loggerhead, Caretta caretta, and leatherback, Dermochelys coriacea, turtles in Kwazulu-Natal, South Africa
Submitted in fulfilment of the requirements for the degree of Master of Science in the Department of Zoology at the Nelson Mandela Metropolitan University.
Loggerhead and leatherback sea turtles nest on the beaches of the north-eastern portion of Kwazulu-Natal within the iSimangaliso Wetland Park. Loggerheads place ~60 % of all nests within an 8 km stretch of beach, whereas leatherbacks tend to space their nests more evenly along the entire length of the monitoring area. The study aimed to determine nest site fidelity of loggerheads and leatherbacks and the factors that influence nest site selection of both species within the 56 km of turtle monitoring area (32N to 100S) and the 5 km area of high-density loggerhead nesting (0N to 12N). The effectiveness of nest site selection was then determined through the hatching success of loggerheads over the 5km area (0N to 12N).
