Abstract
A review was carried out of the mammalian fauna of the Kilum-Ijim forest in the mountains of northwest Cameroon. The purpose was to examine the loss of species, particularly of larger mammals, and the implications of this for forest ecology. Information was collected by direct observation, hunter interviews and a literature review. The forest is the largest remaining representative fragment of the West African montane forest habitat. Seventy-seven species of mammal have been recorded in the forest over the last 50 years. Most are small, especially rodents, bats and insectivores. Seven species are endemic to the Kilum-Ijim area. The process of species extirpation probably began over 100 years ago with the loss of the mega-fauna, possibly beginning with elephant Loxodonta africana (several generations ago), and certainly with buffalo Syncerus caffer (at least 20 years ago), and other large mammals. Remaining large mammal population densities are very low and many species are close to regional extinction. The long-term consequences of these extinctions is uncertain but, as many tree species are monkey- or ruminant-dispersed, severe ecosystem damage has probably already occurred. Human population density in the area is around 300 people per sq km, and no sustainable offtake of wild animals will ever be possible that would provide more than a few grams of meat per person per year from the forest. The protein requirements of the communities of the area will have to continue to be supplied from domesticated stock. Since 1987 the Kilum-Ijim Forest Project of BirdLife International has been working to conserve the remaining forest, using a community forestry approach in collaboration with traditional and local authorities and the government of Cameroon. The project is investigating ways to improve the production of domestic animals outside the forest boundary.
