Theme 1.00

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

Project: 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.

Work will take place at a range of sites across Australia and include case studies of threatened species population recovery.

Response of the Kangaroo Island Dunnart and other threatened species to a cat eradication program

Project: 1.1.10
Controlling feral cats on biodiversity-rich islands is a high priority for the conservation of Australia’s biodiversity. This project will document the benefits of the Kangaroo Island (KI) cat eradication program on the KI dunnart and other threatened species. It will also fill knowledge gaps about the ecology and improve monitoring techniques for the KI dunnart.

Conservation of the Night Parrot

Project: 1.1.11
The Night Parrot was ‘missing’ for nearly a century. Since its rediscovery in western Queensland in 2013, we are building knowledge of its ecology, the threats it faces, its status, and how to manage the landscape for its conservation. This project will build on previous research to enable land managers to make better decisions on how to conserve the parrot.

Feral cat distribution, abundance, management and impacts on threatened species: collation and analysis of data

Project: 1.1.2
This project will improve our understanding of feral cat impacts and how to mitigate those impacts. At national scale, it will collate and analyse large and diverse sets of data to estimate cat distribution and abundance, and measure predation rates by cats on birds, reptiles and mammals, and to identify the ecological traits that make some species more susceptible to cat predation than others.

Integrated management of feral herbivores and feral predators

Project: 1.1.6
This research will uncover how feral cats respond when an abundant source of rabbits is removed from the landscape. Do they prey switch and increase their impact on native animals? Do many die of hunger? We will conduct a landscape-scale experiment at the Arid Recovery reserve in South Australia to find out.

Some responses of the threatened Northern Quoll to a large-scale cat baiting program in the Pilbara

Project: 1.1.7
This project will build on an existing large-scale feral cat baiting program in the Pilbara being undertaken by WA DBCA in partnership with Rio Tinto in order to advance our understanding of how the Northern Quoll and other native species respond to feral predator control, and how to optimise future cat baiting programs more generally.

Conserving critical and threatened habitats

Project: 1.2
This project will study how best to conserve threatened ecological communities and critical habitats for threatened and endangered species. Initial focus is on the Box Gum Grassy woodlands and endangered Buloke Woodlands of the Riverina and Murray-Darling Depression Bioregions as well as Alpine Bogs and Fens. Research will include a series of field trials, experiments and prioritisation of management of critical habitats and threatened ecological communities from across Australia.

Enhancing critical habitat for the Pink-tailed Worm-lizard in agricultural landscapes

Project: 1.2.1.6
Box Gum Grassy Woodland and derived native grassland, is an endangered ecological vegetation community which often occurs in agricultural landscapes. Within this community rocky outcrops provide critical habitats for a wide range of flora and fauna, such as the vulnerable Pink-tailed Worm-lizard.

Adaptive management of endangered Buloke woodlands

Project: 1.2.2
Buloke Woodlands were once widespread in Mallee regions of south eastern Australia but have been extensively cleared and degraded by grazing and cropping. Remaining patches within National Parks are degraded and failing to regenerate. Grazing by kangaroos, rabbits and goats is consider the major barrier to regeneration but the current grazer control regime has failed to yield the desired result. The project team is working with Parks Victoria to investigate why key species are not regenerating and to test management techniques that could improve the recovery of this endangered ecological community.

Supporting alpine peatland recovery by prioritising action on threats

Project: 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.

Managing fire regimes to save threatened flora and fauna

Project: 1.3
This project will improve fire management strategies and conservation outcomes to save threatened flora and fauna from extinction.

On-ground trials and experiments, new data, modelled scenarios and improved management practices will assist fire management authorities to implement sustainable fire regimes and avoid further declines in threatened species.

Disease and faunal declines

Project: 1.4
​Researchers are working with on-ground management authorities to help control three wildlife diseases that threaten our fauna: chytrid fungus, toxoplasmosis and myrtle rust, and to prevent the extinction of affected species.
