|Red List Category & Criteria:||Vulnerable D2 ver 3.1|

|Reviewer(s):||Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)|
Listed as Vulnerable because it is known from only a single location (Pemba Island), where ongoing active conservation activities have significantly reduced the plausibility of future declines of this species.
|Range Description:||This species is endemic to the island of Pemba in Tanzania, where it occurs at elevations from sea level to 45 m asl.|
Native:Tanzania, United Republic of

|Population:||In the early 1990's the population of this species appears to have been reduced to a few hundred animals at most (Mickleburgh et al. 1991). Entwistle and Corp (1997) reported that in 1997, 94% of the of population was restricted to 10 roosts (of 41 in total) with a total estimate of 4,600 to 5,500 individuals. Entwistle (2001) reported that more recent local participation in survey work had helped to give a more accurate population estimate of ~6,900 bats (Trewhella et al. 2005). The population of bats has continued to increase and by the end of 2006 there were ~19,000 animals (Juma 2007).|
|Habitat and Ecology:||This species has been recorded from primary forest, secondary forest, undisturbed traditional grave yards and mangroves. Will roost in several different species of trees, including large examples of non-native trees (such as Mango). According to Pakenham (1984) the species has been recorded roosting on the small islands off Pemba's coast, with bats flying to the mainland at sunset to forage. Seehausen (1990) concluded from interviews with inhabitants of Pemba that the species used to occur in the western parts of the island, which was once covered with rain forest, and not in the eastern, drier parts.|
|Major Threat(s):||Much of the natural forest habitat of this bat has been cleared or severely fragmented. The species has been hunted for food with the use of shotguns replacing traditional methods, resulting in an unsustainable use (Entwistle and Corp 1997). As of 2005, hunting had been reduced but not stopped on Pemba (Trewhella et al. 2005). An additional threat is posed by the collision of bats with overhead electric cables.|
|Conservation Actions:||Ongoing awareness raising on the importance and uniqueness of the endemic fruit bat, and the need for sustainable hunting, has been undertaken through environmental education programmes (Trewhella et al. 2005; Juma 2007). Income for the local community is being generated through bat related ecotourism activities (Juma 2007). It has been reported from the recently gazetted Ngezi-Vumawimbi Nature Forest Reserve and Msitu Kuu Forest(Pakenham 1984; Juma 2007). Illegal logging and the invasive umbrella tree (Maesopsis eminii), that degrades the habitat of this bat, are being controlled within the Nature Forest Reserve (Juma 2007). This species is listed on Appendix II of CITES.|
