incubation period between 45-70 days depending on weather conditions
major threats include:
DENR designated the Batangas Terminal coastline as a nesting ground sanctuary for Olive Ridley sea turtles.
DENR also designed a training program to help Chevron staff protect and care for the nesting sites and hatchlings.
Since 2016, employees and Chevron business and community partners have removed between 1.5 and 2.5 tons of marine debris yearly from the San Pascual coastline.
The nesting period from October 2018 to March 2019 yielded six nesting sites, an increase of 300% from the previous year.
At one of these nesting sites, 77 hatchlings emerged from a clutch of about 100 eggs.
