Feral Pigs By Blake Helwig

When Was the Species Introduced Into Australia? Pigs were brought to Australia on the first fleet by early European colonists in the early 1880’s. Pigs are not native to Australia.

Why They Were Introduced? Domestic pigs were introduced to Australia by early settlers. Accidental and deliberate releases resulted in the wild pig population in Australia

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.

Diseases Associated With the Feral Pig? Feral pigs carry endemic diseases such as leptospirosis, brucellosis,and melioidosis. Also the Australian community if foot and mouth disease were introduced to Australia. Is estimated at $3billion in lost of trade.

Control Techniques? It is important to control feral pigs to prevent the build up of large numbers. Trapping, shooting and poisoning are effective control methods.

How Is the Species Population Regulated? By using control techniques, as said already you need to trap, shoot or poison.

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 Digging for food. It has a major impact on vegetation and forest litter, particularly along drainage lines and around swamps and lagoons, or after rain when the ground is softer. These actions upset stream banks and speed up erosion
