The conservation status of several African colobines has been studied extensively during recent years; however, this is not the case for the West African black-and-white colobus monkeys, notably Colobus polykomos dollmani of Côte d'Ivoire. In 2003 and 2004, we conducted surveys in three forest reserves and Marahoué National Park between the Sassandra and Bandama rivers in Côte d'Ivoire to assess the status of the primates there, with a special focus on Colobus p. dollmani. Thirteen primate taxa were expected in the south-central part of the interfluvial region. We confirmed the presence of eight, including Colobus p. dollmani. Only two of the eight taxa, however, were found to be relatively frequent in all of the four protected areas: Cercopithecus (c.) lowei and Cercopithecus p. petaurista. The presence of Cercopithecus (diana) roloway and Pan troglodytes verus in all four reserves could only be inferred from interviews with local people. Procolobus badius badius was mentioned as present by local people in only one reserve. We detected Colobus p. dollmani in only one of the forests visited but indirect evidence of its presence in a second reserve. Poaching and habitat destruction are the main threats to this subspecies as well as to the other taxa. Without immediate and vigorous action, this colobine taxon will probably be extinct in the near future.
