BIOSECURITY RISKS OF THE WET TROPICS
FERAL PIGS
20 JANUARY 2026
Feral pigs (Sus scrofa) pose a serious threat to the delicate ecosystems and agricultural landscapes of the Wet Tropics.
Highly invasive and destructive, these animals uproot native vegetation, spread weeds, prey on wildlife, and damage crops—causing both environmental degradation and economic loss.
WHAT ARE FERAL PIGS?
Feral pigs (Sus scrofa) are highly destructive, invasive animals found across the Wet Tropics. They damage ecosystems by uprooting vegetation, spreading weeds, and preying on native wildlife. Their presence also threatens agriculture, causing crop losses and soil erosion.
WHY ARE THEY A THREAT?
- Environmental damage: Pigs disturb soil, degrade waterways, and destroy native habitats.
- Agricultural losses: They eat crops, damage fencing, and compete with livestock for food.
- Disease transmission: Pigs can spread diseases like leptospirosis and foot-and-mouth disease.
- Increased weed spread: Their movement spreads invasive plant seeds, worsening weed infestations.
HOW TO CONTROL THEM ON YOUR PROPERTY
The Cassowary Coast pig trapping guide provides a comprehensive overview of what is involved in a successful trapping program, but the key elements are:
- Installing smart traps: Set up remote-controlled enclosures in high-activity areas.
- Using pre-baiting: Encourage pigs to enter traps by providing food sources.
- Monitoring remotely: Use cameras and sensors to track pig activity before triggering the trap.
- Following ethical guidelines: Ensure humane handling and disposal of captured pigs.
