The Pemba flying fox Pteropus voeltzkowi is a fruit bat endemic to the
island of Pemba, off Tanzania. A total of 41 reported roosting areas
were visited in June and July 1995, and 19 occupied roosts were locate
d, most of them in the west of the island, and on small islets off the
west and south of Pemba. Roosts were situated in primary forest, seco
ndary forest (overgrown clove plantations), traditional graveyards and
mangrove areas. A range of sizes and species of trees were used Its r
oosts. The minimum population of P. voeltzkowi was estimated to be bet
ween 4600 and 5500 individuals. In total 94 per cent of the population
was located at 10 roost sites. Larger colonies were associated with r
oosts located in forests, which together supported 75 per cent of the
total bat population. Colonies were of mixed sex, but no young or obvi
ously pregnant females were observed. Major threats to this species ap
peared to be hunting and deforestation (both logging and cleaving for
agriculture) and P. voeltzkowi is considered to be endangered.
