Tortoises & Freshwater Turtles

No other group of vertebrates is facing extinction like turtles. Nearly half of the 330 species are imminently threatened. Ten species have populations of less than 100 individuals.

Challenges

Over-exploitation, for both local and international markets, has caused many populations to decline to unsustainable levels. Recovery efforts are complicated by the high levels of international pet trade, particularly in some of the rarest species. They are also traded for traditional medicine and as meat. Turtles often fetch a high price, creating economic incentives for hunters and wildlife traffickers. In addition, population declines of turtles are made more severe in many areas by habitat destruction, particularly the loss of wetlands.

Our Goal

WCS is committed to the recovery of turtle species. Our strategies to accomplish this center on two key components: reducing the number of adults lost and increasing the number of juvenile turtles entering into the population annually.

Specific tactics include:

Why WCS?

8 regions

35 of the 63 most endangered turtles and tortoises live in eight of our priority regions.

1,000 hatchlings

The Magdalena river turtle is among the many species we’ve reintroduced or supplemented the wild population of recently. In 2015 alone, we released over 1,000 hatchlings of this species in Colombia.

On Our Strategies

Build Law Enforcement Capacity

In Laos, Vietnam and China, WCS is actively involved in training and supporting police, customs and judicial officials in monitoring and preventing the illegal wildlife trade


Working with Local Communities to Reduce Poaching

In Myanmar, WCS supports local partners to protect the last nests of the Burmese Roofed Turtles both in the and in ex-situ breeding facilities. WCS also protects the last population of the Southern River terrapin in Cambodia (there are wild populations in Malaysia, as well). Head-started juveniles have been released annually with acoustic transmitters to monitor the movement of the turtles between freshwater habitats and the brackish mangrove forests of the river's mouth.


Work with Local Communities

In Colombia, over a thousand hatchling Magdalena river turtles were released as part of a community effort to protect the turtles' nests from floodwaters. And in Ecuador, WCS works with local indigenous communities to manage five artificial nesting beaches for the giant Amazonian River turtle. More than 2,000 turtles have been returned to the wild to date.


At Our Facilities, Work to Maintain Critically Endangered Turtles and Tortoises

It is the hope that WCS can link the turtle and tortoise breeding programs at the city zoos with the field programs in the near future, particularly for species that are functionally extinct in the wild and where captive breeding may be the only means of preventing the extinction of the species.


Provide Veterinary Care to Confiscated Turtles

WCS experts are frequently called to step in and assist turtles and tortoises that have fallen victim to the illegal pet trade. For example, the radiated tortoise in Madagascar. On a 2025 episode of WCS Wild Audio, hear how WCS’s Bronx Zoo, as a member of the Association of Zoos and Aquariums, assisted in the aftermath of a large confiscation.
