Feral animals are a major threat to the ecological and economic values of northern Australia. Feral livestock, particularly pigs, as well as cattle, horses and buffalo wreak havoc on the natural environment, displace native species and threaten agricultural production.
In addition Indigenous groups have raised concerns about the damage feral animals inflict on rivers, wetlands and estuaries. Turtles, water lilies, and crocodile eggs are among the traditional resources being impacted. Adding to the complexity of this problem is the desire from Traditional Owners to preserve populations of feral pigs and buffalo as a readily available source of meat for remote communities.
Millions of dollars have been and continue to be invested in feral animal management programs. This research seeks to link such management activities with quantified, long term outcomes for environmental and cultural assets. In doing so it will define indicators of success in feral animal management that are applicable to other parts of northern Australia.
The research will explore the extent of the damage being caused by feral animals to aquatic ecosystems and the methods to best control them. The researchers will work with Indigenous ranger groups, local communities and agencies to achieve this goal. By ensuring that all key management groups are involved in the project, the researchers aim to foster a shared understanding of the most effective and efficient ways to manage feral animals to deliver joint social, environmental and cultural benefits.
This project builds on and works alongside state and federal funding programs that have been awarded to Indigenous groups Balkanu, Aak Puul Gnangtam and Kalan Enterprises over the past five years to control feral animals in Cape York’s Archer River Basin. With support from Balkanu and funding awarded through the Australian Government’s Biodiversity Fund, Kalan and APN rangers installed pig exclusion fencing around key wetlands and compared the results to unfenced sites.
This NESP project will add value to the continued management of feral pigs by ranger groups by providing a very high standard of scientific support. The NESP team will work closely with APN and Kalan to develop a joint understanding of what works and what doesn’t in both the feral animal management and monitoring and evaluation space. This will provide important information that will help design relevant monitoring methods and reporting frameworks that can be shared with other land managers across northern Australia.
Field research is taking place in the Archer River basin, which flows from the McIlwraith Range to the west coast of Queensland’s Cape York Peninsula. It focuses on key areas of impact from feral animals.

Thermal and asphyxia exposure risk to freshwater fish in feral-pig-damaged tropical wetlands
Waltham, N., & Schaffer, J. (2018). Thermal and asphyxia exposure risk to freshwater fish in feral‐pig‐damaged tropical wetlands. Journal of Fish Biology, 93(4), 723-728. |
The project is being led by Dr Justin Perry from CSIRO. Dr Perry will be supported by researchers from CSIRO, James Cook University and the Queensland Government.
Kalan Enterprises, Aak Puul Ngantam (APN Cape York) and Balkanu are essential project collaborators on this project. They will conduct extensive feral animal management activities in the region for the next two years as part of their funding through the Balkanu Feral Pig Management project, Nest To Ocean, Working On Country and Queensland Land and Sea Management funding.
