Theme 1.0

Taking the threat out of threatened species

Identifying and effectively controlling the prevalent threats being faced by species close to extinction is crucial to their conservation.

General principles will be developed and tested to reduce key threats based on research at carefully chosen sites around Australia.

This theme will focus on:

  • Developing evidence-based management tools and protocols to reduce impacts of introduced predators on threatened mammals
  • Conserving critical and threatened habitats
  • Managing fire regimes with thresholds to save threatened flora and fauna

Impacts and management options for introduced predators

Impacts and management options for introduced predators

1.1
Feral cats and foxes, as well as changed fire regimes and introduced herbivores, have caused many species extinctions and remain a serious threat to Australia’s vertebrate species, especially its mammals. This research aims to find the best management actions to reduce the impacts of feral predators, and help restore native animal populations including threatened species.

Supporting alpine peatland recovery by prioritising action on threats

Supporting alpine peatland recovery by prioritising action on threats

1.2.3
Alpine peatlands are an endangered ecological community in Australia and are critical habitat for a large number of threatened species. They are subject to a wide variety of interacting threats that vary greatly across the landscape. Managing and recovering alpine peatlands is hampered by a lack of knowledge about how different alpine peatlands respond to different management interventions.

Saving threatened frogs with refuges from disease, fish predation and fragmentation

Saving threatened frogs with refuges from disease, fish predation and fragmentation

1.4.1
This project will identify and create safe havens for the Endangered spotted tree frog and threatened bell frog species. Disease caused by chytrid fungus, predation by non-native fish and habitat loss are all contributing to these species’ declines.
The role of toxoplasmosis in mammal declines

The role of toxoplasmosis in mammal declines

1.4.2
Toxoplasmosis was introduced to Australia by cats, who also continue to spread the disease. It is known that the disease affects Australian mammals, and that many Australian mammals are suffering dramatic declines. It is completely unknown, however, whether toxoplasmosis is contributing to these declines and how it compares to other threats.
Understanding and combatting myrtle rust

Understanding and combatting myrtle rust

1.4.3
This project will advance our understanding of the plant disease myrtle rust and help to combat its impacts, which affects both threatened and commercially important species. First detected in 2010, it has spread rapidly and caused localised plant extinctions.
