ACKNOWLEDGMENTS My sincere appreciation goes to World Wide Fund for Nature (WWF-carpo) through KFW Cameroon for funding this study. ABSTRACTPreuss's red colobus is critically endangered and endemic to Cameroon and Nigeria. It is one of the least studied red colobus species and therefore further knowledge about the species is crucial for conservation work. Activity budget of Preuss's red colobus was carried in the southern part of Korup National Park, South West region of Cameroon for 18 months and was aimed at contributing to the understanding of the species general behavioural pattern for conservation. Time interval scan sampling method was used for this study. Two thousand three hundred and three individual observations were recorded from 273 group scans for 462 hours. Results revealed general activity time budget for the species, activity related to seasonality, period of the day and age class. In general, this species spent 1: 1: 1: 4: 2 resting, feeding, moving, others and socializing respectively. In wet season they spent more time in all the activities 1: 1: 1: 1: 4 resting, moving, feeding, other and socializing respectively more than in the dry season. Their activity budget within a day revealed the following results: feeding 9: 7: 6 afternoon, morning, mid-day respectively, moving 1: 1: 4 mid-day, morning, afternoon respectively, resting 1:1:2 mornings, mid-day and afternoon respectively, socializing 4: 1:0:2 mornings, mid-day, afternoon respectively and other 1: 1: 3 morning, mid-day, afternoon respectively. Results on the activity budget of age class indicate that adults spent more time feeding (16.31%), resting (25.72%), moving (13.09) than juveniles and infants but infants spent more time socializing (5.55%) than adults (1.58%) and juveniles (00%). This study therefore gives a basic clue of activity budget of Preuss's red colobus, specific for Korup National Park, experiencing human threat. This information can play an important part for the proper management and conservation of this species.

This study was carried out in Korup Region to investigate the reasons for hunting preuss's red colobus (PRC) in Korup National Park (KNP) Cameroon in order to contribute to its sustainable management. Questionnaires (open and closed end) were used to gather personal information from hunters on different hunting tactics, reasons for hunting PRC and threats to this species in KNP for a period of one month (January 2014). One hundred and eighty-seven hunters responded to questionnaires that were distributed in all 5 villages in the park and 5 other villages randomly selected from the 23 villages surrounding KNP. Excel software was used and all variables were used to calculate relative proportions. Results showed that 53.5% of hunters use shotguns and 46.5% use both shotgun and wire snares in hunting. Majority of the hunters (46%) practice both hunting and farming, 32% practice solely hunting, 18% practice hunting and fishing, and 4% practice hunting, farming and fishing. A large proportion (73.3%) of hunters does hunt PRC for protein and income. However, 45.3% of them do not eat PRC because of its bad odour, and 22% do not eat it because the meat is hard. Hunters in KNP depend on hunting for their survival. Therefore, this calls for conservation action, such as introducing an alternative source of livelihood and protein to hunters, which will help to improve their standard of living and supply protein for their healthy growth, thereby discouraging hunting.
