Therma South, Inc. (TSI), an Aboitiz Power Corporation subsidiary, recently released 67 hatchlings from the first of five sea turtle (pawikan) nests found along the shoreline of the power plant in Binugao, Toril, Davao City. TSI team members, local barangay officials, and experts from Ridge to Reef Environmental Consultancy participated in the conservation event. Ridge to Reef also conducted a Marine Turtle Management Training for security personnel of TSI.
Close to 500 eggs were first discovered in April, after an Olive Ridley mother pawikan was observed in the area earlier this year. Experts relocated 115 eggs from the first nest to a safer location. Subsequent nests contained 76, 88, 108, and 109 eggs, respectively.
The plant’s coast has been a known nesting ground for Olive Ridley sea turtles, with a nesting mother frequently returning and laying eggs. Ridge to Reef President Marie Antoinette Pana-Tautho explained that two factors could explain why the mother pawikan did not lay eggs on TSI’s shore during those years: “The gap in nesting timing from 2019 to 2024 may be attributed to the survival rate of previous hatchlings released in the wild, or the mother pawikan nesting on the nearby beach area instead,” she explained.
Thirty pawikan hatchlings were first discovered and released at TSI in December 2018. The next year, 303 hatchlings from four nests followed. Pawikan nests were found again in 2024, with 86 of 120 hatchlings released by TSI team members, officials from the Department of Environment and Natural Resources – Environmental Management Bureau, and Aboitiz Cleanergy Park caretakers trained to handle pawikan hatchlings.
“It is very important to manage marine turtles, especially since we believe that according to a study in 2019, there are three species in the area: Olive Ridley, Green Sea Turtle, and Hawksbill Sea Turtle,” Tautho said.
Currently, the Safety, Health, and Environment Department of TSI, led by Environmental Supervisor Geol. Reeka Angela Llenado, closely monitors the remaining pawikan nests. The team has built barricades around the nests to protect them from predators like birds, dogs, snakes, and even humans.
Olive Ridleys, while the most abundant of all the sea turtles, are considered a vulnerable species by the International Union for Conservation of Nature.
“We will continue to actively monitor our shoreline and help protect its marine biodiversity as part of our environmental stewardship and communal responsibility in its host communities of Davao City and Sta. Cruz,” shared Llenado.
