Pemba flying fox

Distribution and habitat

The Pemba flying fox occurs only on Pemba, an island about 50 kilometres (31 mi) off the coast of Tanzania. Roosts occur in large trees in both primary and secondary forest, among mangroves, and in traditional graveyards. In the latter the bats are often safe and undisturbed as people seldom visit these places because of taboos. There may be up to 850 bats at a single roost.

Biology

Colonies of the Pemba flying fox roost during the day in large trees, emerging at dusk to forage for fruit such as figs, mangoes and breadfruit. They also eat leaves, flowers, pollen and nectar. Seeds that they swallow pass through their guts and are dispersed to other locations. Young seem to be born between June and August and become independent several months later.

Status

The IUCN lists this bat as being "Vulnerable. Its range is limited to the island of Pemba off the coast of Tanzania and it is traditionally hunted for food. This hunting became unsustainable when shotguns began to be used. Another threat to the bats is the ongoing destruction of their forest habitat.

During the early 1990s there were only a few hundred individuals remaining. Conservation measures implemented by the Forestry Department on Pemba include an education campaign, the establishment of wildlife clubs to protect nearby roosts, and continuous monitoring of the population. Also, the hunting of these bats with shotguns is now banned on most of the island. The local population has been involved in conservation measures and bat-based ecotourism is producing extra revenue for the island. With these measures in place, the number of bats has increased and by 2007 there were estimated to be about 20,000. The population appears to have continued to increase, with numbers nearing 29,000 in 2011.
