Priority Species? Yes
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 Northern Quoll is the smallest of the Quoll species and is a solitary carnivorous marsupial that makes its den in rock crevices and tree holes. They are predominantly nocturnal and have short life spans, with males living to approximately 1 year and the oldest recorded female being 3 years. Northern Quolls consume of wide variety of prey including beetles, grasshoppers and hunt a wide variety of vertebrates including possums, rats, snakes and frogs.
Threats
The most noticeable threat that is currently observed is the result of the lethal ingestion of Cane Toad toxin which has substantially declined the population over the last 10 years and it is predicted that Cane Toads will colonise all of the Northern Quoll's range within the next 10-20 years.
Quollity Conservation Hub's Vulnerability Score:
37
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.
