Abstract:Mapping of the foraging habitat areas of The Grey-headed flying fox in New South Wales. The Grey-headed flying fox is listed as a threatened species under state and Commonwealth legislation. The key threatening process for the species is loss of foraging habitat, and recovery actions aim to identify and protect key foraging areas.This project defined foraging habitat for Grey-headed flying foxes, ranked native vegetation within the range of the species according to the quality of foraging habitat it provides.

Purpose:
Jurisdiction:NSW, Australia
Custodian organisation:NSW Department of Environment,Climate Change and Water (DECCW)
Lineage:Digital map layers were created from GIS layers of vegetation mapping. A standard table of habitat attributes has been joined to ARCView shape files of the various map layers compiled for this project. The resulting data layer contains relevant information provided by the original vegetation classifications and maps as well as 23 fields of data from this work that can be queried.
These are:
1. vegetation type the name given to the plant assemblage in the relevant vegetation classification and map
2. source a citation for the source classification and map
3. nectar species list of diet plants in the vegetation type as defined in the source material. A standard five letter code is used. The first two letters identify the genus, the following letters identify the species. Additional letters are added where needed to differentiate species with similar names. Refer to regional profiles.
4. rank n & f the final habitat scores for all vegetation types
5. rank nectar only the final habitat score of nectar-producing vegetation types
6. rainforest score the species richness score attributed to rainforest vegetation
7. tot wt pr weighted productivity * reliability scores for each vegetation type using data from all diet species (bi- monthly phenologies not taken into account).
8. total prod productivity scores for each vegetation type using data from all diet
species
9. total reliability reliability scores for each vegetation type using data from all diet
species
10 23. bi-monthly nectar habitat ranks and nectar scores for each vegetation type.
Nectar habitat ranks, area-weighted productivity * reliability scores, productivity
scores and reliability scores are presented for each bi-month.
It is important for users of this project to be aware of the limitations of the habitat maps. The maps are representations of vegetation patterns across a landscape and should not be interpreted as accurate depictions. Levels of spatial accuracy vary between and within the various mapping projects that were compiled to define feeding habitat for Grey-headed flying foxes. Nonetheless, the maps are sufficiently accurate at a regional scale to support the method used to rank habitat. The maps do not replace site assessments by land managers. Rather, they provide a context for determining whether a site assessment is needed and for interpreting the results. It is possible from these maps to establish whether feeding habitat for Greyheaded flying foxes occurs in the vicinity of a site of interest and to determine the ranks assigned to those habitats. If feeding habitat occurs within the surrounding area, then field inspections should be used to clarify the vegetation type(s) present in the actual site of interest and to confirm the occurrence of key diet species (wt p*r >0.65) as listed in the 54 regional profiles.
