Tortugas Preciosas de Osa is a nonprofit program of IDEHS (ONG) dedicated to the conservation of sea turtles in the Osa Peninsula.


Playa Preciosa is a key nesting ground for three endangered species of sea turtle found worldwide. Our program is dedicated to protect these species. We achieve this goal by integrating conservation, research and education.

Many factors contribute to sea turtle population declines including pollution, poaching, urban development and climate change. These factors are responsible for the loss of nesting grounds or low hatchling survival rate leading sea turtles to the brink of extinction.

Volunteers are key stakeholders to evaluate, monitor, preserve, and conserve sea turtles and their nesting grounds; helping sea turtles first hand in the Osa Peninsular
We monitor and protect nesting turtles on 4 km of beach on the Golfo Dulce of the Osa Peninsula:

We gather information about the nesting activity, predation rates and hatchling success of the three species of turtles that nest on this beach.
Our presence deters poachers from stealing eggs.
We give presentations and courses to different members of the community and groups about sea turtle conservation.


As an volunteer, you will part of morning and night beach patrol with the help of staff and other field assistants.

During these patrols, you will:

  • Take biometric measurements of nesting mother turtles.
  • Assist in the application of identification tags.
  • Record data on turtle tracks and nest location
  • Perform nest excavations when needed and relocate vulnerable nests to our hatchery or safer sectors on the beach
  • Evaluate hatching success rates.
  • Monitor nesting sites for hatchlings and predators.
  • Carry out nest protection techniques and assessment of potential risk factors.
  • Mark and nest protection with bamboo net, method to stop predation by dogs to nest

After patrols, you will:

  • Enter and check data on our data base.*
  • Ensure equipment is cleaned and ready for the next patrol.
  • Monitor the hatchery for hatchlings and perform temperature checks for our hatchery of over 200 nests.

Other tasks include:

  • Training patrol leaders for a partner organization.
  • Giving presentations to various groups and local schools, as well as the eco-tourists from local resorts.
