Service Projects
During the day, primarily work on beach cleanup and hatchery projects. At night, embark on walks to gather eggs and release baby turtles.
Sea Turtle Basics
Costa Rica has four types of sea turtles: the critically endangered Hawksbill, the endangered Green turtle and the vulnerable Leatherback and Olive Ridley turtles. These sea turtles play an important role in the environment. They help maintain healthy seagrass beds and coral reefs. Their nests provide nutrients that contribute to coastal vegetation. Plus, the turtles play a role in controlling the jellyfish population.
Threats to Survival
The sea turtles have natural predators both on land and in the water, including animals that eat turtle eggs. However, human activities pose the greatest threat. The refuge has rivers on each side that feed into the ocean. Trash and debris in those rivers go out to sea and then come back in on the waves. That pollution hinders the ability of mother turtles to find a safe spot to dig a nest and lay eggs.
On top of that, the sea turtles are victims of fishing nets and poachers who use turtle eggs to make a popular bar drink. During one 2022 session, students saw how pervasive the hazards are. When they went on a dolphin-viewing boat ride, they encountered a sea turtle in distress. It had a life vest wrapped around one of its flippers. In response, one of the boat guides jumped into the water to cut the vest off the sea turtle.
Service Work
Students work diligently to remove hazards and save turtle eggs throughout the program,
2022 traveler Candace Leovao says one night she could see with her own eyes why this work is important.
“We had just cleaned up wood and the twigs, and then a turtle laid eggs there that night. So I could see that we were making a difference,” Candace said.
Once the eggs are laid, the students gather them to bring them to a hatchery. Last summer the number of eggs collected was staggering.
The final number: 6,403 eggs collected
Once the eggs hatch, the students bring buckets of baby turtles to the beach near the water and release them. They use red lights to help guide the turtles toward the water.
This program offers a unique opportunity to work directly with park rangers to save sea turtle species!
