Why Have They Survived So
Well?
• Feral pigs live were there is
warm weather they like to
sun bake. They don’t like
hot weather because they
don’t have sweat glands so
they roll around to keep
cool.
Also they have to be around
water to keep refreshed. Pigs
like the scrub like lignum
they hide and sleep in there.

prevent the build up of large numbers.
Trapping, shooting and poisoning are
effective control methods.

What Effects Does the Feral Pig
Have on the Landscape and
Indigenous Flora and Fauna?
• Eating or destroying native plants and animals
• Wallowing in fouling and disturbing soils in dams,
waterholes and other moist or swampy areas
