Programme roles

Direct Conservation icon  Ark
For the Mauremys nigricans the ark role is the most important role as the species is most probably extinct in the wild (the last observation was recorded in 1920). The wild population was decimated by combination of habitat loss and over-harvesting for food. This direct conservation role contemplates maintaining a long-term ex-situ population for future options including reintroduction. To fulfil this role, the EEP needs to find partners and coordinate this effort.

For the Mauremys nigricans research is needed on finding more about the origin habitat of the species and its ecology. Currently, there is only little known about this, while this is essential for the planning of reintroduction in the future.

Is the most important direct conservation role assigned for the three other Mauremys species included into this EEP. The programme aims to maintain a long-term ex-situ population to preserve future options. Those populations are managed to provide individuals for augmentation of wild populations

 Research/training (in range countries)
The research would focus more on the genetic origin of the various Mauremys ssp to avoid hybridization. To fulfil this role, financial support is needed to improve security in the in-range centers, to prevent theft of animals.
Indirect Conservation icon  Education
The EEP presents a good opportunity for institutions that hold the species to educate visitors about confiscations. This term may include issues of illegal pet trade, trade of parts for medicinal use, etc.

Programme numbers
