After 130 million years of existence, the future of these magnificent creatures depends on us
There are seven species of sea turtles in the world and all of them are considered threatened or endangered due to poaching, predation, habitat disturbance and degradation, and in-water threats. The world’s sea turtle populations are incredibly susceptible to human and environmental threats and are in urgent need of global protection.
The southern beaches of the Osa Peninsula are visited primarily by two species of nesting turtles: Olive Ridley (Lepidochelys olivacea) and Green Sea Turtle (Chelonia mydas). Leatherback sea turtles (Dermochelys coriacea) and Hawksbill sea turtles (Eretmochelys imbricata) are also occasional visitors. Intriguingly, the different sea turtle varieties visit the Osa at varying times with significantly oscillating intensity:
Our sea turtle conservation program monitors the nesting activity, predation rates, and hatchling success of these incredible species. Our staff and volunteers gather important population and reproductive data, while helping deter and educate poachers who collect turtle eggs for consumption or sale. Osa Conservation has been collecting data and working in communities to support outreach and protection of sea turtles for over ten years. Primary work has been located at the Piro Beach and Pejeperro beach, both of which are considered to be critical nesting sites on the Osa Peninsula. Our efforts have been paying off, with hatching rates rising significantly, by the thousands, over the past few years:
