The roan antelope, endemic to Africa, is drastically declining in Kenya and most of its range throughout Africa. Extensive research on roans in South Africa has not provided effective remedial management actions. The solution to Kenya's roans will come from detailed research in Kenya. This paper reports an on-going research on "mapping and modelling the roan antelope population and habitat in Ruma National Park, Kenya. " The research is employing the state-of-the-art techniques in modelling and geographic information systems (GIS). Preliminary findings indicate that (i) the roan population has declined to 45 animals; (ii) the roans' home range changes (a) with any slight change in surface water and/or rainfall frequency and (b) between and within seasons (dry and wet); and (iii) the roans' behaviour implies possibilities of poaching. Among other interventions, establishment of a roan sanctuary (with intensive active management) in Ruma N. Park seems to be the best way forward.
