Common Name(s):
English Moluccan Naked-backed Fruit Bat
Synonym(s):

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hutson, A.M., Suyanto, A., Helgen, K., Maryanto, I. & Sinaga, U.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern because it is widespread, abundant, and there is no reason to believe the population is in decline.

Geographic Range [top]

Range Description: This species ranges from Timor, Samau (I. Maryanto pers. comm.), Maluku Islands (including Ambon, Bacan, Buru and Seram islands), Banda Islands, throughout much of the island of New Guinea (Indonesia and Papua New Guinea), including the Kai and Aru Islands (Indonesia) to Australia, where it is restricted to the Torres Islands and Cape York, Queensland. It is also found on Waigeo, Batanta (Ibhu pers. comm.), Salawati, and Yapen in Indonesia. It has an altitudinal range of sea level up to 2,700 m asl.

Population [top]

Population: It is the most abundant and widespread fruit bat on Papua New Guinea (Bonaccorso 1998). It is generally rare in Australia (Strahan 1995). Few specimens are known from Buru island but it is common on Seram and Banda. It is uncommon on other islands.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species is found in tropical moist forest, wet open forest, rural gardens, and fruit and coconut plantations. It is generally absent from dry woodland and savanna. It roosts in caves, sinkholes, boulder piles, old mines, disused buildings, and dense vegetation. It is a gregarious species. In New Guinea, colonies may contain several thousand animals. In Australia, colonies are generally much smaller. Females annually give birth to a single young (Flannery 1995; Strahan 1995; Bonaccorso 1998; Duncan et al. 1999).
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats to the species throughout its range. Habitat loss, due to active logging is a threat along with hunting for food and mining activities for Nickel on Gag. It is also locally threatened in parts of its range by shooting as a pest species, and accidental mortality on barbed-wire fences (Bonaccorso 1998; Duncan et al. 1999),

Conservation Actions [top]

Conservation Actions: It is known from a number of protected areas. There is a need to ensure the protection of important roosting sites. Bonaccorso (1998) mentions a large roosting site of some 10,000 bats at a village near Omeru (Papua New Guinea), where local villagers have provided protection to the bats and offer walking tours to view the roost for a small fee. Taxonomic work is needed to resolve the status of this species relative to D. magna.
