Its sharp claws and teeth help it to break open bamboo stalks and to defend itself against predators. Now, it is estimated that approximately 200 million feral rabbits inhabit Australia.Introduction of European Rabbits to AustraliaIn 1859, European rabbits (Oryctolagus cuniculus) were introduced into the Australian wild so that they could be hunted. The effect of rabbits on the environment has been catastrophic. Rabbits seemed an obvious choice to an Englishman, but they weren't native to Australia. * Changes in Numbers and Distribution related to Climate and Land Systems in Semiarid North-Western New South Wales.. Roy-Dufresne E et al. Feral rabbits were found throughout most of their current range by 1910. Rabbits were first introduced to Australia by the First Fleet in 1788. Soil type. [37] By the winter of 1996, the virus was established in Victoria, New South Wales, the Northern Territory and Western Australia.

Upon arriving in Australia, which had no native rabbit population, Austin asked his nephew William Austin in England to send him 12 grey rabbits, five hares, 72 partridges, and some sparrows so he could continue his hobby in Australia by creating a local population of the species. Populations of animals competing with rabbits grew. The native quolls predated upon rabbits[3] and prior to 1870, many accounts recorded quolls impeding their establishment on the mainland while island colonies thrived. A population of 24 rabbits were released near Geelong in 1859 to be hunted for sport. With abundant food sources, good ground cover and a lack of predators, the rabbits raced across the landscape. By 1886 they were found throughout Victoria and New South Wales - extending to Western Australia by 1894, and into the Northern Territory by the 1900s. The Duke of Edinburgh shooting rabbits in Barwon Park, Victoria, in 1867, N Chevalier, engraving, Rabbits around a waterhole during myxomatosis trials at Wardang Island, South Australia, Syringe used in myxomatosis trials at Lake Urana, New South Wales in 1954, National Archives of Australia A1200, L44186. In 1997, a final segment was built connecting it to the Dingo Fence. Free from diseases and facing relatively few predators in a modified environment, the wild populations grew rapidly.

The native quolls predated upon rabbits and prior to 1870, many accounts recorded quolls impeding their establishment on the mainland while island colonies thrived. Besides their lack of natural predators on the continent, theirsuccess is aided by quickbreeding: They can birth more than four litters a year with as many as five kits (baby rabbits) each. It is believed that the carnivorous marsupials of the mainland, such as quolls, were able to keep rabbit numbers down. Owners of domestic rabbits were advised to vaccinate their animals.

Rabbits usually get all the water they need from the plants they eat, except during drought when they require access to water within approximately 0.4 km of their warren. Why? Its diet consists mainly of bamboo, but it also eats fruits, eggs, and small animals. [19], 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. To control their population, scientists introduced a rabbit-specific virus into the population, and their numbers greatly decreased.

These introduced species have had a major impact on our country's soil and waterways and on native plant and animal diversity. A Royal Commission was held to investigate the situation in 1901. How did Australia get rid of rabbits? They rapidly overpopulated because they had few natural predators in the area . They rapidly overpopulated because they had few natural predators in the area. Within 50 yearsrabbits had spread across almost the whole of Australia. [43], 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. The first extensive fences were built in central New South Wales and the initial success of private fencing encouraged state governments to construct even longer ones. Rabbit Flat Roadhouse. The history of rabbits in Australia is a deadly example of how humans can affect wildlife, and of the havoc invasive species can wreak on our ecosystems. [4] Quolls were systematically exterminated[5] by colonists to defend introduced species such as chickens.
