The project will take place at Jozani-Chwaka Bay National Park and Biosphere Reserve, which covers two primary sites: the National Park itself and the surrounding local villages where red colobus monkeys are found. This reserve serves as a key site for the conservation of the endemic Zanzibar red colobus monkeys (Piliocolobus kirkii) on Unguja Island, Zanzibar, which is currently facing significant human pressures.

The primary objective of the project is to improve conservation efforts for the Zanzibar red colobus monkeys within Jozani-Chwaka Bay National Park and the Biosphere Reserve. This will be achieved through a series of comprehensive activities. First, an intensive field survey will be conducted to evaluate the spatial distribution and population status of the colobus monkeys. Second, a questionnaire survey will be administered to assess the threats to these monkeys and to measure the perceptions of local communities residing in all ten Biosphere villages. Third, the project will include an assessment of land use and land cover (LULC) changes in the habitat of colobus monkeys over the past three decades (2004, 2014 and 2024) to identify the rate of forest transformation as time goes on.

In addition to these efforts, the project will collaborate closely with local communities and conservation organizations found within the project site, such as the Jozani Environmental Conservation Association (JECA) and UWEMAJO, throughout all phases of data collection. This collaboration aims to raise awareness about the significance of preserving habitats for the conservation of endangered red colobus monkeys and other rare wildlife species in the area, such as the Adder’s duiker. Again, to ensure community involvement and awareness, workshops will be conducted in September 2025 that bring together local communities, park rangers, local leaders, conservation organizations, and government representatives for result sharing. These workshops will not only disseminate the survey results but also promote awareness about the conservation of colobus monkeys.

Furthermore, the insights gained from the land use and land cover change assessment will inform conservation initiatives, potentially leading to the development of restoration programs if necessary. Overall, this project aims not only to protect the red colobus monkeys but also to foster a sustainable relationship between local communities and the environment where the monkeys reside.
