This
island is located in the western Indian Ocean, 40 km off of the
coast of mainland Tanzania and 80 km distance from the island of
Zanzibar (Unguja). The island was originally forested, but only
remnants of the primary forest remain. The vegetation is
dominated by plantations of cloves and other spices, although
many of the clove plantations have been abandoned and are now
dominated by secondary growth forest.
Ngesi is the last
significant area of moist forest surviving on Pemba and although
the reserve covers 1440 hectares, only 550 hectares are actually
forest, the remainder being evergreen thicket. Nevertheless it
constitutes an invaluable resource, for it contains a number of
unique and endangered species. Mammals of interest include the
Pemba vervet monkey, the Pemba blue duiker and the Pemba flying
fox. The latter is actually a large fruit-eating bat and a roost
of over 200 is known to exist deep within the forest. Also
present is a large troupe of Kirk's colobus monkey, which were
settled here from Josani in the sixties in an attempt to
increase their range. The most interesting trees are the three
globally rare species of mjoho (Odyendea zimmermanni),
Chrystalido pembanus and Ensete proboscoideum. It is
also thought that there are likely to exist a number of unique
small plant and insect species, which have not yet been
recorded. Ngesi will hopefully be soon upgraded to the status of
National Park in order that this pool of unique genes will be
saved for future generations. In the meantime, the forest seems
quite well protected, although there are reports of limited
raiding by local people in search of firewood and other forest
products. The staff at the ranger post run a nature trail, but
it's the sandy road that passes through the best sections of the
forest.
