1,000 Radiated Tortoises Released on World Turtle Day®

A Step Forward for Tortoises in Madagascar

In another step forward for a critically endangered species, Turtle Survival Alliance released 1,000 Radiated Tortoises (Astrochelys radiata) on World Turtle Day®, May 23, 2024, into a community-protected forest in southwest Madagascar. These tortoises were seized from illegal trafficking and put under Turtle Survival Alliance management for rehabilitation, long-term care, and eventual release.

The first successful reintroduction of tortoises began in 2021, with thousands of tortoises released in batches since then. The tortoises will be monitored post-release to record movements, quantify survivorship, and qualify release efficacy. We aim to rewild more than 20,000 confiscated tortoises under our care in Madagascar over the next five years. To learn more about our plan, read our case for support.

In preparation for returning the tortoises to the wild, a veterinary team from Saint Louis Zoo WildCare Institute and Mississippi Aquarium working with husbandry staff from Zoo Knoxville, Wildlife Conservation Society, the Smithsonian Institute, and the Turtle Survival Alliance, and students from the veterinary school of the University of Antananarivo, performed health evaluations for tortoises large enough to be considered for release. The 1,000 cleared for release were placed in an isolation enclosure for six months prior to their transfer to the reintroduction site.

Concurrently, we, in close collaboration with Madagascar’s Ministry of Environment and Sustainable Development (MEDD) and other government institutions, and the local community, invested considerable effort to prepare the site for tortoise release. The MEDD declared the site a community-managed area. TSA and the local community conducted surveys to establish boundaries and constructed expansive pre-release enclosures. TSA and its partners (gendarmes, MEDD) built capacity among community members to manage the site for tortoises and as a community forest.

The release is a day of celebration for the community, marking a collaboration between local communities, our organization, and the government to achieve a significant step towards the conservation of this endemic species in need.
