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!

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.
