Ostional Wildlife Refuge is the second largest beach nesting site of Olive ridley sea turtles (Lepidochelys olivacea) in the world. With the simultaneous arrival of hundreds of turtles to the beach of Ostional, high mortality of eggs was observed due to over-excavation, illegal poaching of eggs and natural causes. This promoted the creation of the Refuge and the design of a project where government institutions and the community jointly implemented actions to improve the conditions of habitat protection and a regulated use of turtle eggs is permitted.
