The Cuora Box Turtle Project

___________________________________________________________________________________________________________

Overview

Turtles of the genus Cuora are considered some of the most critically important for conservation as they have been seen in large numbers in the illegal wildlife trade in Vietnam and China. While illegal collection from the wild is the main threat to the species, habitat loss throughout its range is also concern. Of seven species of Cuora occurring or believed to occur in Vietnam five are critically endangered and one is endangered. Three important species within the genus are the Indochinese Box Turtles, (Cuora galbinifrons), Bourret's Box Turtle (Cuora bourreti) , the Lesser Indochinese Box Turtle (Cuora picturata). All of these species are critically endangered (IUCN, 2010) the latter two of which are localized endemics found only in central Vietnam (Stuart & Pharam 2004).

Another ATP priority species is the Keeled box turtle (Cuora mouhotii) and the subspecies Cuora mouhotii obsti . Despite the Keeled box turtle's large distribution, it is listed as endangered by the International Union for Conservation of Nature (IUCN) and numbers have declined drastically in some areas.

Distribution

The Indochinese box turtle has a relatively small range, it occurs in China, Laos and north & central Vietnam while Bourret's box turtles are thought to be endemic to Central Vietnam and the Lesser Indochinese box turtle endemic to the southern mountainous regions of Vietnam.
The Keeled box turtle has a larger range, it occurs in China, Vietnam, Lao People's Democratic Republic, Thailand, Myanmar and in India (Ernst, Altenburg and Barbour, 1997; The Asian Turtle Consortium, 2007; EMBL Reptile Database, 2007). Its subspecies Cuora mouhotii obsti occurs in the Annam mountain range in central Vietnam.

Habitat

Cuora galbinifrons, Cuora bourreti and Cuora picturata are terrestrial species that occur in woodlands and evergreen forests at mid to high elevations in their respective range (see range maps above).

Cuora mouhotii, also a terrestrial species, occurs in forests often associated with limestone areas. The species is frequently found in small caves and rock crevices of rocky, mountainous regions.

Threats

Intensive hunting pressure throughout the range of these Cuora species has dramatically reduced wild populations. The over-collection for local consumption and for the national and international food and pet trade poses a major threat to these species which is also compounded by habitat loss and degradation, due to deforestation and shifting cultivation.
With growth to maturity taking over a decade and low fecundity, only two or three eggs laid a year, this species is unable to sustain even low levels of collection. Globally they also remain poorly represented in captive collections in zoos or in assurance colonies and have proven difficult to keep or breed in captivity.



Above: In 2007 the Danang Forest Protection Department (FPD) confiscated these box turtles (Cuora bourreti and Cuora mouhotii). All animals were transferred to the Turtle Conservation Centre (TCC) in Cuc Phuong National Park. Confiscations like this have become rare, indicating that wild populations of box turtles in Vietnam are nearly depleted
