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
All subspecies of the long-nosed potoroo are omnivorous, feeding on fruits, seeds, leaves, roots and flowers, and invertebrates with the most significant food source is sporocarps of hypogeal fungi. The long-nosed potoroo are intricately linked to forest ecology through the food web, as their physical disturbance of the soil helps to improve soil condition and moisture penetration and the consumption of the underground fungi helps to disperse the fungal spores.
Threats
The main threat to this species is the predicted population decline of 33 percent in the next three generations as a result of the 2019-2020 bushfires, compounding existing threats from habitat degradation and predation by European red fox and cats. The species requires a habitat that has been unburnt for a long period (>20 years) with the species unlikely to recover to pre-fire population abundance before the next major bushfire event.
