The presence of researchers, ecotourists or rangers inside protected areas is generally assumed to provide a protective effect for wildlife populations, mainly by reducing poaching pressure. However, this assumption has rarely been empirically tested. Here, we evaluate and quantify the conservation benefits of the presence of a long-term research area in Taï National Park, Côte d'Ivoire. A wildlife survey following 225 km of line transects revealed considerably higher primate and duiker encounter rates within the research area when compared with adjacent areas. This positive effect was particularly pronounced for threatened and over-harvested species, such as the endangered red colobus monkey ( Procolobus badius ). This pattern was clearly mirrored by a reversed gradient in signs of poaching, which decreased towards and inside the research area, a trend that was also supported with park-wide data. This study demonstrates that even relatively simple evidence-based analytical approaches can bridge the gap between conservation theory and practice. In addition, it emphasizes the value of establishing long-term research sites as an integral part of protected area management.

The Tanzania-Zambia railway now bisects the Magombera Forest Reserve in Tanzania, and as a result the most viable surviving population of the rare endemic Iringa red colobus is seriously threatened. The railway has facilitated tree-felling, settlement and cultivation, and the colobus habitat is already seriously damaged. The authors conducted a survey of the forest in 1979, and recommended that the southern part, which has a viable colobus population, be included in the neighbouring Selous Game Reserve, thus giving that part the stronger protection of a game reserve, and that the local people be compensated by the release to them of a small area of the Selous.

Colobus Monkey

There are five, perhaps only four, monkey species in The Gambia and all are under threat. The main problems are habitat destruction, hunting of crop raiders and illegal capture for medical research. The information presented here was collected during a long-term study from March 1978 to September 1983 on the socio-ecology of the red colobus monkey in the Abuko Nature Reserve. Further information was collected during brief periods between February 1985 and April 1989 on the presence of monkeys in the forest parks. It is not systematic nor extensive, but it indicates clearly that action is needed if monkeys are to remain as part of the country's wildlife. The most pressing need is for survey work to supply the information needed to work out a conservation plan.
