Every picture tells a story, they say. However, just how accurate and relevant that story may be is dependant on the context in which the picture appears and the preconceptions and expectations of the viewer. Things are not always what they seem.

This widely circulated series of images depicting the collection of turtle eggs from a beach in Costa Rica is a case in point. The photographs themselves are perfectly genuine and they certainly do show the harvesting of turtle eggs. However, this egg harvest is not an illegal poaching operation nor is it an environmentally destructive "attack against nature" as suggested in the text that accompanies these photographs.tvb now,tvbnow,bttvb2 z7 `! r+ r8 t* q1 z: l7 O

Instead, the turtle egg harvest is an important part of a long-term environmental project developed and managed by the Costa Rican government. The photographs show an egg harvest by villagers at Ostional beach, a remote community near Punta Gurones on Costa Rica's Pacific coast. In 1983, the Costa Rican government created the Ostional Wildlife Refuge in the area and later initiated the Egg Harvest Project (EHP). The EHP allowed villagers to continue their traditional practice of harvesting eggs while furthering the long term goal of assisting in the conservation and recovery of the Olive Ridley turtle species. The harvests are strictly controlled, with villagers only allowed to take eggs within the first day and a half of each egg laying event, known as an "arribada". An article about the Olive Ridley turtle published on the Ocean Actions website notes:tvb now,tvbnow,bttvb) y5 z/ i' m! U9 ~# J

As thousands upon thousands of Olive Ridley turtles climb on to a stretch of Playa Ostional, 70-80% of previously laid nests are crushed or dug up during the subsequent nesting. It is for this reason that the Egg Harvest Project is justified. Villagers wait and watch, harvesting the eggs laid in the first day and half of the arribada.

Assessing a sea turtle population is a challenge, but nesting data in Ostional indicate a stable population. A major contribution to the success of the Egg Harvest Project is the lack of decomposing eggs. If the (sic) left unharvested, the early nests that are destroyed by later nesting females act as a source of bacteria that can contaminate the later nests.
