How you can help: Our TSA India Program conducts surveys and population structure assessments of sympatrically associated freshwater turtles inhabiting the lesser and greater Saryu (Ghaghra) and Chambal rivers and riverine wetlands of the Ganges River in North India; the Pink-Ringed Tent Turtle is one of the species among those. Additionally, TSA is on the front line of combating poaching and trade of India‚Äôs turtles. We regularly provide law enforcement with critical information, train law enforcement officials in identifying and handling smuggled turtles, triage and provide long-term medical and husbandry care for turtles seized from wildlife trade, return confiscated turtles to the wild, and provide community outreach. You can help us further these activities and expand our impact by supporting this and other programs like it!
