Acknowledgements


This recovery plan has been developed with the involvement and cooperation of a broad range of stakeholders, but individual stakeholders have not necessarily committed to undertaking specific actions.

This recovery plan is based on the extensive work of many flying-fox experts. It has benefited from the diligence of Commonwealth and state government officers, the Commonwealth Threatened Species Scientific Committee, the NSW Flying-fox Consultative Committee, Department of the Environment and Energy facilitated Grey-headed Flying-fox policy workshops and the CSIRO coordinated National Flying-fox Monitoring Program.

The preparation of this plan was funded by an initial grant from the Australian Government and continued support from the NSW State Government. The NSW Office of Environment and Heritage coordinated the initial drafting of this plan on behalf of the Australian Government.

Executive summary



Current status of taxon


The Grey-headed Flying-fox is listed as Vulnerable under both the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Threatened Species Conservation Act 1995. It is listed as threatened under the Victorian Flora and Fauna Guarantee Act 1988 and as Rare under the South Australian National Parks and Wildlife Act 1972.

Habitat and distribution


The Grey-headed Flying-fox has historically occupied forests and woodlands in the coastal lowlands, tablelands and slopes of south-eastern Australia, from Bundaberg in Queensland to Geelong in Victoria, with rare sightings outside its range. More recently, camps have established in Adelaide, the Australian Capital Territory and inland areas of central and southern New South Wales and Victoria.

Threats to species survival


The primary known threat to the survival of the Grey-headed Flying-fox is loss and degradation of foraging and roosting habitat. Conflict with people, including disturbance in camps and mortality from actions to manage commercial fruit crops, is considered to be a moderate threat, but is increasing in urban areas. The level of threat caused by electrocution on power lines and entanglement in netting and barbed-wire fences is unknown. The impact of climate change on Grey-headed Flying-foxes is also unknown but increasing temperatures and drought conditions are likely to degrade foraging and roosting habitat, influence the frequency of foraging in commercial orchards, cause heat stress and increase heat related mortality.

Recovery objectives and actions


Actions under this plan aim to improve the national population trend; identify, manage and secure key foraging and roosting habitat; improve the community’s capacity to coexist with flying-foxes; and increase awareness about flying-foxes, the threats they face and the important ecosystem services they provide as seed dispersers and pollinators.

Criteria for success


Success of this recovery plan will be evaluated against:


  • a robust estimate of improved population trend,

  • an improved understanding of habitat critical to the survival of the species

  • an increase in protection of habitat critical to the survival of the species and nationally important camp sites

  • implementation of effective habitat restoration projects

  • a reduction in the level of conflict in sections of the community affected by problematic flying-fox camps

  • greater uptake of crop netting under existing subsidy schemes, and

  • an improved understanding of threats of unknown status; climate change and electrocution/ entanglements.
