Carpentarian Rock-rat
Zyzomys palatalis
Australia's Threatened Species Category
Endangered
Listed since: 15/02/2019
IUCN's Threatened Species Category
Critically Endangered
Listed since: 5/06/2015
Population trend: Unknown
Other names: Aywalirroomoo
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
The Carpentarian Rock-rat is a small rodent, and as with other rock-rats, is known to lose its tail, fur and skin very easily. The Carpentarian Rock-rat is restricted to isolated rainforest thickets and broad-leaved vegetation on scree slopes in rugged sandstone gorges. Their diet is believed to consist of fruits, seeds and nuts.
Threats
The main threat to the Carpentarian Rock-rat is inappropriate fire regimes and large feral animals, particularly pigs, can damage waterholes and surrounding vegetation.
Quollity Conservation Hub's Vulnerability Score:
56
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.
