Protecting the Northern River Terrapin

Our next field report comes from the Bhawal National Park in Bangladesh where the Northern River Terrapin (Batagur baska), one of the rarest turtles in the world, is having another good year!

Five of the six known females in the area have already nested, laying a total of 101 eggs! TSA is hopeful that the sixth female, which was discovered in a local pond and joined the breeding program in October 2013, will also produce eggs. All nests have been moved to a caged protected area on the beach for incubation, and temperatures are being carefully monitored in an effort to produce more females.

As in some other reptile species such as crocodiles, river terrapin sex is determined by environmental temperature after fertilization (Temperature dependent sex determination). Lower temperatures produce male hatchlings while a higher temperature will usually result in females. More females mean more eggs and a brighter future for this critically endangered species…
