Grey-headed Flying-fox
Pteropus poliocephalus
Australia's Threatened Species Category
Vulnerable
Listed since: 19/03/2021
IUCN's Threatened Species Category
Vulnerable
Listed since: 27/08/2021
Population trend: Decreasing
Other names: None
Priority Species? No
The Australian government's Threatened Species Action Plan 2022-2032 selected over 100 priority species derive from consultation with threatened species experts and the wider community. While all species are important, focusing on a limited number of species can help target effort and resources so that outcomes can be achieved, measured and shared.
Description
Grey-headed flying-foxes are social and nocturnal. During the day they gather in camps, hanging from trees or other structures. One camp can contain tens of thousands of bats. The size and location of camps changes depending on the availability of food, and their social organisation is complex. Grey-headed flying-foxes are an important pollinator and seed-disperser of many trees, and play a key role in the maintenance of forest habitats.
Threats
Grey-headed flying-foxes are threatened by any activity that destroys their foraging and roosting habitats, such as clearing of vegetation and urban development.
Quollity Conservation Hub's Vulnerability Score:
45
To help compare the relative vulnerability of different species, we have developed a scoring system based on biological and ecological characteristics that influence a species' ability to survive and recover from environmental change and natural disasters.
The framework is adapted from assessment methods used by conservation experts following the Black Summer bushfires to help identify species most in need of conservation action, research, and recovery funding.
Each species is assessed using a range of factors, including its conservation status, lifespan, reproductive rate, habitat and dietary requirements, ability to disperse or recover after fire, and the number and severity of threats it faces.
In general, the higher a species' score, the greater its overall vulnerability and risk of decline or extinction.
Like all conservation assessments, this scoring system is limited by the information currently available. Many threatened species remain poorly studied and receive limited research funding, meaning some assessments rely on the best available scientific knowledge or information from closely related species. As new research becomes available, scores may be updated to reflect our improved understanding.
