Summary:
The Vietnamese Pond Turtle, Mauremys annamensis (Family Geoemydidae), is a medium-sized (carapace length to 285 mm in females, 232 mm in males), highly aquatic turtle known only from the lowland wetlands of central Vietnam. Field records are limited and the natural history of M. annamensis is poorly known, in part due to the difficulty in conducting research within the species’ native range as a result of conflict and political isolation during much of the period since its description. Recent work has delimited the historical distribution and gathered evidence for the historical abundance of M. annamensis, but also indicates that the species has largely been extirpated across its range and is now extremely rare in the wild. Over-collection and habitat loss are the greatest contributors to the species’ decline, while pollution and interspecific hybridization may represent additional threats. Substantial international trade in M. annamensis occurred in the past, and despite national and international protection for the species, surviving populations continue to be threatened by intensive collection efforts. In captivity, the species acclimates well and breeds readily, with females capable of producing several clutches of eggs per year. Current conservation efforts include greater enforcement of trade restrictions, the establishment of a protected habitat area, and planning for future reintroductions from captive stocks. Continued research and conservation measures are required to save this critically endangered species.
