Roloway Guenon
Cercopithecus diana roloway (Schreber, 1774)
CR A2acd+3cd+4acd

The roloway guenon is a very beautiful, medium-sized monkey, known from the tropical forests of Ghana and Côte d’Ivoire. These forests have undergone significant development throughout the latter half of this century, including logging activity more intense than in any other part of tropical Africa, and typically this has been accompanied by increased bushmeat hunting and conversion to agricultural lands that prevents forest regeneration. Even in areas where it was formerly abundant, most hunters report that it has not been seen for years, and its population probably has declined at least 80% in the last three generations. Recent surveys did not find it in Ghana’s Bia National Park, where it was probably eliminated between the mid-1970s and 1990, and its presence can be confirmed only in one protected area, the Ankasa/Nini-Suhien Conservation Area. It is, however, still believed to occur in at least seven forest reserves in Ghana (Boin River, Boi-Tano, Dadieso, Draw River, Krokosua Hills, Tano-Nimuri and Yoyo River). The Krokosua Hills Forest Reserve is a particularly important site, since it also harbors the white-naped mangabey (Cercocebus atys lunulatus).
