Features of Natural Interest

Monitoring is carried out during the breeding season by counting and recording tracks and successful nests on the beach from the night before. This is not an absolute measure of green turtle population size however, as a female will nest more than once each season. Track counts therefore need to be divided by the number of clutches each female lays. A project carried out in 2012 found that the average number of clutches laid by each female to be 6 (range 4-8) each season. The outlook is positive, with green turtle nests on Long Beach, the main nesting beach on the Island, having increased from approximately 1000 in 1977 to nearly 10,000 in 2013.
