Research and conservation activities of the Cape Verde loggerhead turtle (Caretta caretta) nesting population started on Boa Vista Island 15 years ago. Nowadays, Cape Verde is regarded as the third world largest loggerhead turtle rookery. The number of nests per season may fluctuate from year to year. On Boa Vista, the averaged number of nests has been estimated to be between 12 and 14 thousand. Occasionally, as in 2012, more than 20,000 nests have been reported. Cape Verde is the only stable loggerhead nesting ground in Eastern Atlantic. Major threats to this population come from illegal hunting of adult turtles, mostly nesting females, and the loss of habitat because of coastal tourist development.
For the last 14 years, BIOS.CV members have been dedicating large efforts in the study and conservation of marine turtles in Cape Verde, having been also involved in activities aiming at making competent authorities, native population and tourists aware of the importance of protecting these endangered species and their critical habitats. Furthermore, we have also encouraged sustainable development practices among locals.
