Beyond the Bale : December 2011
December 2011 BEYOND THE BALE 28 ON-FARM The Invasive Animals CRC is developing information toolkits on best practice pest animal management in Australia. The PestSmart toolkit provides farmers and land managers with a single information resource on the key pest animals in Australia. Toolkit publications can be used individually as a snapshot of a particular control method or program, or together as a comprehensive best practice management guide. The toolkit is being developed for the three main pest animals that adversely affect the profitability of woolgrowers' businesses: wild dogs, foxes and rabbits. Wild dogs and foxes in some areas kill up to 25 per cent of lambs born each season. Rabbits damage grazing land and decimate native vegetation. The toolkit is also being developed for feral cats, feral pigs, carp and tilapia. FAST FACTS l The new PestSmart Toolkit is an information toolkit for practical pest animal management, developed by the Invasive Animals CRC and supported by AWI. l The toolkit includes information on the three main pest animals that adversely affect the profitability of woolgrowers' businesses: wild dogs, foxes and rabbits lPestSmart Roadshows around the country will promote the toolkit and new pest animal control products. PestSmart toolkit for pest management Wild dogs cost the Australian wool industry an estimated $24 million a year in lost production. WOOLGROWERS' WORST VERTEBRATE PESTS It is estimated that invasive animals cost Australia at least $744 million annually in economic, environmental and social damage. Invasive animals cost the wool industry alone $71 million annually, and this figure doesn't include the environmental or social costs. RABBITS Wild rabbits are Australia's most widespread and destructive environmental and agricultural vertebrate pest. First arriving in Australia with the First Fleet, then deliberately released for hunting in the 1800s, the rate of spread of the rabbit in Australia was the fastest of any colonising mammal anywhere in the world. They are now found in all states and territories, including several offshore islands. Rabbits graze on native and introduced vegetation, crops and pastures. Rabbit grazing can prevent seedlings from regenerating and reduce crop yields, as well as increase competition for feed with livestock. Rabbits damage native plants and directly compete with native wildlife for food and shelter. Their digging and browsing leads to a loss of vegetation cover, which in turn can result in slope instability and soil erosion. WILD DOGS Dingoes originated in Asia where they were present possibly 10,000 to 14,000 years ago and were derived from wolves. Aboriginal people brought the dingo to Australia approximately 4000 years ago. The dingo never reached Tasmania. Domestic dogs were brought into Australia by Europeans in 1788 and their release into the wild has continued since. Wild dogs prey on a variety of animals including mammals, birds and reptiles of all sizes from insects to water buffalo. However, they prefer to eat small and medium-sized mammals when available. Wild dogs cost the Australian wool industry an estimated $24 million a year in lost production. However, this figure does not take into account the impact wild dogs have on native animals, biodiversity, mental health and other industries. Stock losses to wild dogs are so severe in some areas as to make production non-viable.
