In water Sea Turtle Studies

Monitor the feeding habits of turtles in the Peninsular de Osa, by laying nets, and catching and taking data from feeding turtles.

The project is located on Playa Blanca, close to Puerto Jimenez on the Osa Peninsula in the southern Pacific province of Puntarenas, Costa Rica. Osa Peninsula is a natural paradise, being home to a vast variety of mammals, birds, amphibians, reptiles and insects. The Golfo Dulce, one of the four tropical fiords worldwide, hosts additionally a fascinating marine life - including sea turtles. Osa In-Water project works to better understand the dynamics of the local populations of hawksbill and green sea turtles, their genetic origin and in-water habitat use and threats. This project also runs a rescue and rehabilitation centre, as well as a mangrove reforestation effort. Studies are also carried out on the health of the off shore sea grass bed, which is an important feeding habitat for many species, especially sea turtles.
