Gwydir Valley Pest Management Initiative

Over the next 12 months the GVIA will be working in partnership with a range of organisations and local landholders to implement a strategic feral pig management program. The program will involve monitoring feral pig populations and the damage they cause to natural ecosystems and crops in and around the Gwydir wetlands. 
The project is being supported by funding from the NSW Government and the LLS under the NSW Regional Weed and Pest Animal Management Drought Funding Program 2018-2019.  
Feral pigs are an area wide issue, effective management of the pest on private and public land is important for the whole region. Control of pig population growth is a priority for landholders and National Parks as they strive to manage the impact feral pigs have on native fauna and flora as well as on grazing and cropping lands. The commitment to work together will ensure that we get the best results from the project.

Project Progress

The project is now well underway.  Since April there have been five recorded aerial shoots, with  over 1,600 pigs controlled. Additionally, there has been an active program of trapping and baiting of pigs. All activities have been conducted by the National Parks and by private land holders. Despite the dry conditions the pig population is still significant, which means control will need to continue.

During August, the team from SQ Landscapes have implemented a collar and camera monitoring program. A number of pigs are being fitted with Global Positioning System (GPS) tracking collars. The movement of these pigs will be monitored over a number of months. This information will help determine where the pigs go for food, water and shelter, and how far they travel in these dry conditions.
Additional to the collars, a number of pigs have been ear tagged and a remote sensing camera grid has been set up. The cameras will monitor pig numbers and movement. Ear tags will identify specific pigs, providing greater insight into individual pig movements. The aim of the grid design is to maximise both the number of cameras that individual animals are recorded on and the number of individual animals that are recorded. Data from the cameras will give landholders a better understanding of abundance and the effectiveness of control activities.
A huge thank you must go out to the landholders and National Parks who are working with SQ Landscapes in this project, without their support none of this would be possible.

Key considerations in the management of Feral Pigs

  • Feral pigs are everyones problem, just because you don't see them doesn't mean they are not there.
  • An integrated area wide management approach will provide the best results for everyone. 
  • At least 80% of the population must be controlled.
  • No single approach will be enough, a combination of aerial shooting, trapping and baiting needs to be employed across a wide area. 
  • Control activities need to be implemented year round, timing control solely on enterprise needs (eg seedling development) is unlikely to be enough. 
  • Pig movements are driven by the need for food, water and shelter, information suggests that they seem to return to shelter zones daily.

The project aims to enhance communication and develop integrated control strategies initiated in and around the internationally significant Gwydir Wetlands. Feral Pig impacts are exaserbated in dry times when the feral pigs tend to congregate around surface water sources. 
The key partners in the project are the NWLLS, the National Parks, the OEH and local landholders.
