So Aldabra tortoises exist in many zoos across the US. They are listed as Vulnerable by the IUCN and there are a very large number of them in Europe as well. However, in looking over the Chelonian TAG RCPs from both 2010 and 2016, there is no mention of Aldabra tortoises in captivity. In both RCPs, they only show up in the total list of chelonian species and nowhere else. I cannot find any information about an AZA program for this species and they are not mentioned in any other documents made by the Chelonian TAG. I found some articles about how the Tulsa Zoo is perhaps the only zoo that has bred them more than once. Here are two articles about that: Aldabra Tortoises Hatch at the Tulsa Zoo | Tulsa Zoo Tulsa Zoo winning race in Aldabra tortoise breeding programs So what exactly is the deal with Aldabra tortoises here? Is there a breeding program or not? Who is coordinating it? Where did all of the tortoises in North America come from?
