Population studies of Lowe’s Monkey (Mammalia: Primates: Cercopithecidae: Cercopithecus lowei Thomas, 1923) in Kakum Conservation Area, Ghana

The status of Lowe’s Monkey Cercopithecus lowei was assessed during a survey in Kakum Conservation Area, Ghana.  Within the reserve logging and hunting was banned 20 years ago, and the forest underwent two decades of natural regeneration.  The main objectives of the study were to evaluate the impact of conservation measures on the local population of Lowe’s Monkey and assess its relationships with other primates and non-primate mammals.  Data on population status were collected during line transect surveys.  Comparing the present mean encounter rate of 1.03 (±0.03) groups/km to that recorded in 1993 (0.31±0.16 groups/km) suggests an average population growth rate of 13.6% per annum.  Conservation measures such as banning illegal logging and hunting have likely contributed to the population increase.  Lowe’s monkeys were often observed in close proximity to other primates (e.g., Black and White Colobus) and non-primate mammals (e.g., Maxwell’s Duiker), but neither socio-positive nor antagonistic interactions were observed.  Recommendations are made for further improvement and studies of the species elsewhere.
