Zanzibar Red Colobus (Piliocolobus kirkii) (Kima punju)
Seven individuals were introduced in Ngezi from Jozani in 1979 to establish a herd.
The numbers incresed and curenlty their numbers are estimated to be over 35
individuals. It is not clear of their exact number, as it is very difficult to sight them.
The colobus are currently confined to the east of the forest in Kisiwani area because to
the west of the forest the colobus were being hunted and there is heavy human
disturbance. No colobus was seen during the foot count but three individuals were
seen on a separate visit to Kisiwani area. There have been no reports of negative
impact arising from the introduction of the colobus in Ngezi or rather it is not
apparent at least at the moment. The forest habitat in Ngezi is very ideal for the
colobus and there is a big potential for the species to increase in numbers.
The Zanzibar red colobus is a species endemic to Zanzibar. It is listed as endangered
in the IUCN threatened species categories and appears in Appendix I of CITES. It was
investigated by Sir John Kirk, the Governor General of Zanzibar in 1868 and named
after him. Other members of the red colobus group are widespread. The Zanzibar red
colobus weighs 7 - 13 kgs. and exhibits diverse dietary habits, sometimes reported as
crop pest. Its preferred habitat includes the ground water, coral rag, and deep soil and
mangrove forests. Occurrence in cultivated and areas under fallow is reported to be
due to loss of preferred habitat. The Zanzibar red colobus is the flagship species of
Zanzibar's terrestrial conservation effort and a major tourist attraction. The
conservation effort of the colobus started over 134 years ago because in 1868 Sir John
Kirk described the colobus as "rare" in Zanzibar. Official role of the colobus
protection began in 1919 and continued during the Sultan of Zanzibar regime. Since
1995 local community support has been sought in the conservation of the colobus.
