Feral predators such as cats and foxes have caused the extinction of many native mammals and remain the most serious threat to the remaining mammal species - especially when combined with mismanaged fire and introduced herbivores.
“Ultimately we want to recommend the best combination of tools for any given landscape and situation to reduce the impacts of feral predators on threatened species and other native wildlife,” says Sarah Legge, who leads Project 1.1 with John Woinarski.
“This project aims to be useful for a wide range of environmental managers, such as state and territory agencies, NGO’s, Indigenous Protected Areas and other groups who manage and care for land, like pastoralists.”
As well as collaborating with project partners to interrogate existing datasets, the project will carry out strategic research to fill knowledge gaps and add value to a variety of field programs being carried out by land management organisations across the country.
Such field programs include landscape-scale baiting for cats using newly developed techniques, integrated control of the introduced herbivores (especially rabbits), testing of new traps like the laser-guided grooming traps for cats, and training livestock guardian dogs to protect threatened species.
“Maremma dogs have been used as livestock guardian dogs for centuries, and proved enormously successful looking after domestic animals like sheep and chickens. The research aims to use these dogs to protect small populations of threatened species from foxes and feral cats.
“We’re also exploring the impacts of fire and grazing on feral cats and foxes, because habitat structure affects their hunting success. So if you can ‘thicken up’ a habitat it probably provides some relief to native mammals.”
The project is of personal interest to Sarah, who has worked with cats in the past, although in quite different contexts.
“My very first two jobs were with cat species and I’ve always liked them. I’ve worked with Scottish wildcats as well as lions in Tanzania. Most recently, I worked with the Australian Wildlife Conservancy on feral cats in the Kimberley.
“The welfare of any animal is important, regardless of whether it’s feral or not. The issue is simply that Australia has to make a choice between having a country of feral foxes, cats and rabbits - or a country that still has its unique native fauna.”
Sarah finds working with such a large and diverse group through the Threatened Species Hub exciting.
“There’s a really great energy amongst everyone involved, and a collective sense that we need to work together to do something about feral cats and foxes before it’s too late.
“Our research team involves a large number of individuals and organisations, so as well as drawing on an enormous body of expertise, our research findings will also have large reach.
“We’re working closely with the Department of the Environment and the Threatened Species Commissioner’s office, including via the feral cat taskforce. We’re really cognisant of what they’re working to achieve, and of aligning our program to help deliver against those national targets,” says Dr Legge.

Properties in the Margaret River region have the opportunity to make a significant contribution to conserving the Critically Endangered Western Ringtail Possum. People don’t often think of possums as needing our help, but there are actually less western ringtail possums in the world than Bengal tigers.
It is Threatened Species Day on 7 September. If you are a threatened species in Australia, chances are you are on Indigenous-managed land, as it is the last stronghold for many species which have been lost from the wider landscape .
New research has found that habitat loss is a major concern for hundreds of Australian bird species, and south-eastern Australia has been the worst affected. The Threatened Species Recovery Hub study found that half of all native bird species have each lost almost two-thirds of their natural habitat across Victoria, parts of South Australia and New South Wales.
Kanyirninpa Jukurrpa (KJ) Rangers in the Martu Determination have collaborated with Threatened Species Recovery Hub scientists to design a monitoring program for mankarr (the greater bilby). Martu people identified priorities for the bilby monitoring program, then worked with Dr Anja Skroblin from The University of Melbourne to co-develop a monitoring method which brings together Martu knowledge and practice with Western conservation science.
