Howard River Toadlet
Uperoleia daviesae
Australia's Threatened Species Category
Vulnerable
Listed since: 13/11/2021
IUCN's Threatened Species Category
Endangered
Listed since: 17/02/2021
Population trend: Decreasing
Other names: Davies's Toadlet
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 Howard River Toadlet is an extremely small species of burrowing frog and is endemic to a small area of the monsoonal tropics in the northwestern Top End of the Northern Territory.
Threats
The threats to the Howard River Toadlet is extractive mining activity which causes habitat loss, residential development and expansion, alteration of surface and ground water hydrology, inappropriate fire regimes, disease and invasive species including pigs, feral cats, cane toads and grassy weeds.
Quollity Conservation Hub's Vulnerability Score:
22
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.
