The aim of control is to reduce the impact of rabbits on farm enterprises and the natural environment. Australian Geographic; Jul/Aug2012, Issue 109, p130 •Pech, R. P. and Hood, G. M. (1998), Foxes, rabbits, alternative prey and rabbit calicivirus disease: consequences of a new biological control agent for an outbreaking species in Australia. [15] The commission received 1456 suggestions, including several schemes involving biological controls (see below), but none was found to be both safe and effective.[16]. With widespread farming, areas that might otherwise have been scrub or woodlands were, instead, turned into vast areas with low vegetation, creating ideal habitats for rabbits. [11], Rabbits are also responsible for serious erosion problems, as they eat native plants, leaving the topsoil exposed and vulnerable to sheet, gully, and wind erosion. However, by 1827 in Tasmania, a newspaper article noted "...the common rabbit is becoming so numerous throughout the colony, that they are running about on some large estates by thousands. Domesticated meat rabbits arrived in Australia with the First Fleet and rabbits were released onto many islands in the Bass Strait and the Tasman Sea to provide sustenance for shipwrecked sailors. In the 1880s, James Moseley ringed Coondambo Station with wire netting and fenced off the watercourses; at the first heatwave, the rabbits perished of thirst. Conventional methods include shooting rabbits and destroying their warrens, but these had only limited success. It causes severe damage to the natural environment and to agriculture. [8] While living in England, Austin had been an avid hunter, regularly dedicating his weekends to rabbit shooting. Various methods in the 20th century have been attempted to control the Australian rabbit population. Such wild rabbit populations are a serious mammalian pest and invasive species in Australia causing millions of dollars of damage to crops. For this reason, biological warfare against rabbits in Australia is a serious concern for conservation activities in other parts of the world. Their population remained fairly stable until around 1866, presumed to have been kept in check by native carnivores and were protected by an Act of Parliament, but by 1867 was out of control. [9] William could not source enough grey rabbits to meet his uncle's order, so he topped it up by buying domestic rabbits. Myxoma virus causes localized benign fibromas in its natural hosts, wild rabbits in the Americas (Sylvilagus spp. In 1857–1858, Alexander Buchanan, overseer for F. H. Dutton's Anlaby Estate in the Mid-North of South Australia, released a number of rabbits for hunting sport. We are working to protect our agriculture and food industries, supply chains and environment during the COVID-19 outbreak. Historical management techniques involved the use of bounty hunters to trap European rabbits in efforts to control the growing populations. [10] Many other farms released their rabbits into the wild after Austin. The first feral populations were recorded in 1827 in south-eastern Tasmania. [40], In southern Europe, the scarcity of rabbits threatens the conservation of endangered predator species higher up the food chain, that depend on small game such as rabbits. Landholders are obliged to control rabbit populations on their land. In a classic example of unintended consequences, rabbits had become so prevalent within 10 years of their introduction in 1859 that two million could be shot or trapped annually without having any noticeable effect on the population. [citation needed] As such, the Number 1 Rabbit-Proof Fence, which was erected in 1901, failed to keep the rabbit population away from the protected area. Department of Sustainability, Environment, Water, Population and Communities, 2011 [23], In 1893, a rabbit-proof fence was commenced in Queensland. It extends from Mount Gipps (near Rathdowney) to Goombi between Chinchilla and Miles. Introduction. [38] The pathogen, a new strain of K5 (RHDV1), is both extremely lethal and highly contagious. [21], Historically, trapping was also frequently used; steel-jawed leg-holding traps were banned in most states in the 1980s on animal-cruelty grounds, though trapping continues at a lower level using rubber-jawed traps. The removal of this topsoil is devastating to the land, as it takes many hundreds of years to regenerate. In September 1887, Dr Herbert Butcher (1854–1893) of Wilcannia found a number of dead, emaciated rabbits at Tintinallogy Station. Poisoning is probably the most widely used of the conventional techniques, as it requires the least effort, and capable of destroying a local population, though reinfestation given the mobility of the animal is almost inevitable. We acknowledge the Traditional Owners of country throughout Australia and recognise their continuing connection to land, waters and culture. They inhabit heathland, grassland, woodland, open meadows and the edges of agricultural land. Hares can breed all year but require high protein green vegetation to stimulate breeding. It causes severe damage to the natural environment and to agriculture. At the same time in NSW, Cunningham noted, "... rabbits are bred around houses, but we have yet no wild ones in enclosures..." He also noted the scrubby, sandy rubble between Sydney and Botany Bay would be ideal for farming rabbits. They are the single most significant cause of the extinction of numerous native plants and animals. The story of the European rabbit in Australia must surely be one of the most amazing examples of an animal's ability to colonise a new land. [12] Rabbits are believed to have had an immense impact on the abundance of natural resource availability, primarily concerning overgrazing. However, when introduced by humans into environments that do not have natural defences against them, rabbits can cause enormous damage.Perhaps the most well-known example of this is the continent of Australia.In Australia, the European Rabbit is the most serious mammalian pest, an invasive species, … [19], Another technique is hunting using ferrets, wherein ferrets are deployed to chase the rabbits out to be shot or into nets set over the burrows. [citation needed], Ring-fencing can be highly effective way of providing a rabbit-free area. However, its decline in its native range (caused by the diseases myxomatosis and rabbit calicivirus, as well as overhunting and habitat loss), has caused the decline of its highly dependent predators, the Iberian lynxa… It sometimes escaped, but failed to survive in the Australian bush. [26] Even after this large scale fence had failed, smaller scale fencing projects continued to make a successful appearance.[27]. Two well-known examples of much more extensive fences are: In July 1884 Ernest James Stevens, a Member of the Queensland Legislative Assembly, proposed that the Queensland Government erect a fence to prevent the infestation of rabbits in New South Wales from spreading into Queensland (his Logan electorate being very close to the New South Wales border). [16], In 1906 and 1907, Jean Danysz, of the Pasteur Institute of Paris, conducted trials on Broughton Island, New South Wales, of a strain of Pasteurella bacteria he had developed, which proved to be specific to rabbits, but it proved to be a less-than-satisfactory control measure. It was progressively extended through the years. Dr Danysz felt that Broughton Island was a poor choice of test site, and that extensive experiments should be conducted on the mainland. Frank Tidswell, who was his chief Australian collaborator, continued Danysz's trials after he left in 1907, and also began trials of the Yalgogrin, Gundagai, and Picton microbes (named for the stations where infected rabbits were found), but financial support was lacking from the Federal government, or the collaboration of affected states, that would be necessary to prove that the measure safe and effective. Given that European rabbits can both jump very high and burrow underground,[25] a perfectly intact fence stretching for hundreds of kilometres, and whose gates farmers or graziers did not leave open for livestock or machinery, was still unlikely to succeed. [28], On 16 April 1888, the New South Wales government appointed a royal commission "to make a full and diligent inquiry as to whether or not the introduction of contagious diseases amongst rabbits by inoculation or otherwise, or the propagation of diseases natural to rabbits ... will be accompanied or followed by danger to human health or life, or to animal life other than rabbits, or to interfere injuriously with the profitable carrying on of agricultural or pastoral pursuits ..." Under the aegis of the commission, tests were conducted at Rodd Island, and although rabbits who were given food adulterated with chicken cholera bacillus were killed, no evidence was found of the contagion spreading to healthy rabbits.[16]. Once the problem was understood, various control methods were tried to limit or reduce the population of rabbits in Australia. Their spread may have been enhanced through the emergence of strong crossbreeds. All of these techniques are limited to working only in settled areas and are quite labour-intensive. Early introductions of European rabbits into Australia were domestic breeds that were unable to survive in the wild. The species is also found in north-western Africa. ); in contrast, it causes a severe generalized disease (myxomatosis) in European rabbits (O. cuniculus), with a very high mortality rate.Currently, myxoma virus is enzootic to the Americas, Europe, and Australia. Within 50 years rabbits had spread across almost the entire continent, with devastating implications for Australia’s indigenous flora and fauna. The feral European rabbit is one of the most widely distributed and abundant mammals in Australia. Here is … European Rabbit, known by biologists as Oryctolagus cuniculus, is the ancestor of most domesticated rabbit breeds. The first of these, in Sydney at least, was one built by Alexander Macleay at Elizabeth Bay House, "a preserve or rabbit-warren, surrounded by a substantial stone wall, and well stocked with that choice game.
