The Macaca Nigra Project has been launched in April 2006 in order to study the ecology, reproductive biology and social system of Sulawesi crested black macaques in their natural habitat and to promote conservation of this fascinating species.

It is a joint project between the German Primate Centre (DPZ), the Indonesian Bogor Agricultural University (IPB), West Java and the University Sam Ratulangi (UNSRAT), North Sulawesi.

The field site is located in the Tangkoko-Batuangus Nature Reserve.
