It is urgent to act for the conservation of sea turtles

Playa Preciosa is a key nesting ground for three endangered species of sea turtle found worldwide... The latter are in the process of extinction and the nests have many predators (dogs, wild animals and the man who consumes the eggs …). Tortugas Preciosas is a little nonprofit program dedicated to the conservation of sea turtles in the Osa Peninsula.  Our program is dedicated to protect these species. We achieve this goal by integrating conservation, research and education.

Our actions on playa Preciosa


We believe that the best way to inspire future generations is to enable travelers, researchers and students from around the world to participate in conservation work. 

Another important part of the educational program is the community outreach. We focus in educating local communities and children at school about sea turtle and conservation.


In our morning patrols we surveyed the beach early morning every day. All nests presents are located, GPS marked and subdequently monitored. When nests are located in a safe place we protect them covering with bamboo meshes (in situ) made by ourlseves, otherwise, we relocate them to our hatchery or to another safer sector in the beach. At the time of hatching, we protect small turtles from predators until they make it safe and sound to the ocean.


On our night patrols we take biometric measumerements of every adult encountered. We also perform a health assessment, measure and mark turtles. 
All data is processed in data bases for further analysis along to other researchers, projects and universities.

Don Florentino Almengor, conocido como “El Chancero” por la gente de Puerto Jiménez, creció en este paraíso llamado la Península de Osa, una de las zonas más biológicamente ricas del planeta sin saberlo. Siempre rodeado de abundancia y un sin fin de aventuras por descubrir, creció andando en la montaña, a caballo, pescando en las lagunas Pejeperrito e incluso cazando y oreando.
El tiempo lo llevó a desarrollarse en otros lugares de la Península como comerciante en fincas y empresas bananeras, sin embargo, finalmente regresó a su origen en Puerto Jiménez y al lugar que lo vio nacer y crecer, pero sobre todo que lo marcó tanto por tanta abundancia.
La semana pasada Don Florentino visitó Tortugas Preciosas para unirse por primera vez en 78 años a una liberación de tortugas. Ciertamente el había conocido en su vida las tortugas adultas, pero nunca había conocido los bebés.
Estaba profundamente impactado de conocer por primera vez una parte del ciclo de vida y de conservación tan importante de estas especies y a nosotros nos llena de esperanza comprobar que nunca es tarde para aprender y apreciar la importancia de la conservación de nuestros tesoros naturales en este paraíso al que llamamos Osa.
La educación a todos niveles nos dará las herramientas para que juntos luchemos por nuestro hogar, nuestra salud y nuestro futuro!

Florentino Almengor, known as “El Chancero” by the people of Puerto Jiménez, grew up in this paradise called the Osa Peninsula, one of the most biologically rich areas on the planet without knowing it. Always surrounded by abundance and endless adventures to discover, he grew up walking in the mountains, on horseback, fishing in Pejeperrito lagoon and even hunting and gold mining.
Time led him to develop in other parts of the Peninsula as a merchant in banana farms and other companies, however, he finally returned to his origin in Puerto Jiménez and to the place where he grew, but above all that, tha place that marked him so much for so much abundance.
Last week Florentino visited Tortugas Preciosas to join a baby turtle release for the first time in 78 years. He certainly had known adult turtles in his life, but he had never known hatchlings.
He was deeply impressed to know for the first time such an important part of the life cycle and conservation of these species and we are full of hope to see that it is never too late to learn and appreciate the importance of the conservation of our natural treasures in this paradise that we call Osa.
Education at all levels will give us the tools to fight together for our home, our health and our future!

Todos los registros de tortuga Carey anidando en nuestras playas son muy importantes, ya que es una especie altamente amenazada, así que cada nido o hembra que encontramos anidando nos llena de esperanza.
Cuando encontramos un rastro de Carey, de inmediato buscamos dentro de la vegetación (como se aprecia en video), pues es una especie que se adentra mucho para anidar, incluso algunas veces hemos tenido que ayudar a algunas hembras a regresar por lo denso que es la vegetación al regresar al mar.
Every record of Hawksbill turtle nesting on our beaches are very important, since it is a highly threatened species, so each nest or female that we find nesting fills us with hope.
When we find tracks of Hawksbill, we immediately look inside the vegetation (as can be seen in the video), as it is a species that goes a long way to nest, sometimes we have even had to help some females to return because of how dense it is vegetation when returning to the sea.
