Taxon summary: Central Long-eared Bat
Scientific Name: Nyctophilus timoriensis (Geoffroy, 1806) (Central form)
Common Name: Central Long-eared Bat
Conservation status: Lower Risk (near threatened)
Past range and abundance
Coolgardie, Hampton and northern Avon Bioregions in Western Australia, Gawler Bioregion and western part of the ‘Eyre and York Blocks’ Bioregion in South Australia. A specimen from Ooldea in the Great Victoria Desert Bioregion of South Australia. One other specimen from a car grill after a night-time drive from Marla (Stony Plains Bioregion of SA) to Alice Springs in the Northern Territory via the Stuart Highway in c.1985. No historical data on abundance.
Present range and abundance
Known from 15 localities in Western Australia and 19 in South Australia. No evidence that range has contracted, but it is apparently rare in Great Victoria Desert, Nullarbor and Stony Plains Bioregions while it is locally common in Coolgardie, Hampton, Gawler and western Eyre-York Block Bioregions.
Gleans ground, bark and foliage surfaces; forages in and against cluttered airspaces. The species is often netted, and sometimes caught in pit traps, in heavy eucalypt woodlands and tall woodlands of the Coolgardie Bioregion of Western Australia with a tall shrub understorey of Melaleuca lanceolata, M. pauperiflora, M. quadrifaria, Eremophila spp. etc. Less common in open woodlands. Has been netted at dams in the Coolgardie and Hampton Bioregions of Western Australia while in South Australia has been associated with a range of mallee (Eucalyptus) species, Acacia papyrocarpa, A. ramulosa, Casuarina cristata and found to the fringes of the treeless Nullarbor Plain.
Too little is known of its ecology and distribution to identify threats. Extensive clearing of mallee for grain crops in the ‘Eyre and York Blocks’ Bioregion, and grazing in the Gawler Bioregion, may have diminished local populations. Populations occur in the Dundas, Jilbadji and Mt Manning Nature Reserves in Western Australia, and on several Conservation Parks in South Australia.
- Investigate taxonomic status by quantifying the morphological and sexual dimorphism differences between the Coolgardie and south-western populations.
- Extend genetic studies to include DNA sequence comparisons with eastern, western and Tasmanian forms.
- Monitor persistence of known populations.
- Carry out ecological research to determine:
- roost and maternity site selection; and
- population-density and dispersal of populations.
