Abstract
In June 1968 an ideal site was found at Ain Kahla in the Moyen Atlas Mountains of Morocco for a study of the wild Barbary macaque Macaca sylvanus L. (Deag and Crook, 1971; Deag, 1970, 1973, 1974, 1977, 1977, 1980). At this site, in the forest of Sidi M’Guild one of Morocco’s major cedar forests, the monkeys are numerous, entirely dependent on natural food, relatively undisturbed and reasonably easy to observe. The study area has since achieved a greater importance. Its wildness, beauty, nearness to Europe and the fascinating male-baby interactions shown by the monkeys soon attracted others wishing to observe wild primates. It has already seen another major study (Taub, 1971, 1978, 1980) and more are planned. Furthermore, it has been suggested that this forest should be established as one of a series of National Parks for the conservation of Moroccan fauna and flora (Taub, 1975). At Ain Kahla the monkeys live in groups with overlapping home ranges (Deag, 1974) and complex behavioural relationships with neighbouring groups (Deag, 1973). This paper summarizes the demography of the groups, based on a fifteen month field study in 1968–69. The project (which was divided into an initial population study and a later single group study) is described in Deag (1974, 1977b, 1980a).
