Research Objectives: The Zanzibar red colobus is one of Africa's most rare and endangered primates and is threatened by continued habitat loss and degradation. They are also a major economic resource in Zanzibar attracting 24,000 paying tourists in 1997. This project monitors the demographics of 17 groups of Zanzibar red colobus (approximately 450 individuals, perhaps 20-30% of all remaining Zanzibar red colobus), provides training in primate conservation management for staff members of the Zanzibar Sub-Commission for Forestry, and compares the ecology, demography and behavior of the Zanzibar red colobus monkey in relation to differences in population density, and food quantity and quality per capita. Census data contributes to the monitoring program initiated in 1991 in Jozani Forest, the agricultural areas south of Jozani Forest, and Masingini Forest. Data on behavior of the Zanzibar red colobus is being collected from the subpopulations in Jozani Forest and the adjacent agricultural areas. These data will contribute to our understanding of the relationships between red colobus population densities and dynamics, behavioral ecology, social structure, and habitat type. This information is crucial for the development of effective conservation management plans for this highly endangered species.

Field Positions and Volunteers: None at present.

Species Studied: Piliocolobus kirkii (Zanzibar red colobus)

Other Species at Site: Cercopithecus albogularis (Sykes' monkey), Galago senegalensis (lesser bushbaby), Otolemur garnettii (Garnett's galago)
