In 2004 an intensive survey of Latakia and other Syrian beaches was undertaken to improve and update knowledge of Syria's marine turtle nesting populations. The survey confirmed that loggerhead turtles Caretta caretta nest in Syria (eight nests recorded), distributed diffusely along the coast, but also identified hitherto undescribed green turtle Chelonia mydas nesting aggregations. The most important green turtle nesting site was the 12 km of beach south-east of Latakia that ranks in the Mediterranean's top 10 rookeries for this species (in terms of maximum number of nests), with 104 of the 106 nests recorded in this study. Mean clutch size of green turtles (108 ± SD 25.1, range 72–164, n = 29) was comparable with other Mediterranean rookeries, and hatching success (percentage of eggs that produced hatchlings) of successful nests was 83.5%. The main problems facing the turtles and their nests were found to be deliberate killing of adults, nest predation and hatchling disorientation. We recommend initiation of annual monitoring and nest protection at the main green turtle nesting beach and investigations of possible at-sea turtle populations together with a campaign to raise awareness and acceptance amongst stakeholders.
