When this stage is fully implemented and maintained, rabbit impact should not return to its former level. This may be because they are inaccessible, i.e. Fumigation is used if warrens have been re-opened after ripping, or in areas which cannot be ripped. If rabbit density is low the objective is to reduce the population further so that it cannot recover quickly. This leaves a streak of dirt which is often visible for some distance. Rabbits have the ability to rapidly re-invade and recolonise areas following control, so control programs should involve as large a number of properties as possible. In Tasmania, the virus is introduced on carrot baits, following a period of pre-feeding to attract rabbits to the bait. Rabbits occur in pockets in some towns and metropolitan areas, with unwanted impacts on house yards and gardens even though they are present only in small numbers. Before deciding on control strategies, monitor rabbit populations using daytime observations and spotlight counts. Shooting rabbits is rarely an effective control method by itself.

To be effective, rabbit control should be conducted in an integrated way, which means adopting a range of complementary control strategies in cooperation with neighbouring landholders. An electric offset wire may be used to enhance the effectiveness of a netting fence, with the benefit of keeping both native and domestic animals off the fence. The warren provides shelter and protection for rabbits, to avoid extremes of weather and predators. By 1887, losses from rabbit damage compelled the New South Wales government to offer a £25,000 reward for "any method of success not previously known in the Colony for the effectual extermination of rabbits". To conduct a Pindone poisoning program, contact your Local Land Services. All burrow entrances must be closed to prevent the escape of rabbits. Keep working dogs well fed and chained when not at work and muzzle them if working in or near a baited area. The disease has steadily become less effective against rabbits due to both attenuation of the virus and increased genetic resistance in the rabbit. Other rabbit harbour includes blackberry, lantana, fallen logs, farm refuse, old machinery and rock piles.

Efforts should be concentrated on reducing the impact of rabbits rather than just focusing on killing rabbits in the short term. The release of eggs in female rabbits is triggered by sexual intercourse, not by a cycle of hormones as in humans. Rabbits usually become infected after being bitten by an insect vector, typically mosquitos, but also European and Spanish rabbit fleas that have been introduced to Australia.

Pindone is typically used where the alternative rabbit poison, sodium fluoroacetate (1080), is either impractical or unsuitable. 1080 must only be used under the supervision of a qualified operator, and there are different laws controlling its use in each of the states of Australia. 7 June 2018 – 2 new RHDV2 cases confirmed. Ideally, the ripper tines should be to a depth of 900 mm, at a spacing of 500 mm. The disease has steadily become less effective against rabbits due to both attenuation of the virus and increased genetic resistance in the rabbit. Follow up control is usually achieved by fumigation and harbour destruction. Even so, when stressed, rabbits will climb over or dig under the best netting fences, so regular checks and maintenance will be needed to maintain the effectiveness of any rabbit-proof fence. When rabbits were culled on Macquarie Island, the resident cats turned to seabirds. They will also girdle young trees and shrubs, chewing the bark down to the heartwood in a circle near the base of the tree. The number of rabbits in a warren is proportional to the number of entrances, so warren size and density can be used to estimate the number of rabbits present. Farmers ripped their warrens, laid poison and shot them but still they multiplied. In addition, two important diseases have been introduced to Australian rabbits; myxomatosis in the early 1950s, and rabbit haemorrhagic disease (RHD), formerly known as rabbit calici-virus disease (RCD), in 1996. Destroying warrens helps to control rabbits. All 1080 users must have chemical risk management training at Australian Qualifications Framework level 3 (AQF3).

Note that warrens may extend under fences, buildings, rock ledges and the root system of large trees. Rabbits were introduced to Australia in the 1800s by European settlers. The story of rabbits in Australia, and the resulting eradication efforts, provides a cautionary tale about viruses and immunity. control at all times to reduce the risk of infection and cross-infection measure, interpret and record rodent and rabbit weight, length, behaviour and other relevant objective indicators of change in physiological status monitor rodent and rabbit health, condition … Regular use of advanced control and monitoring, as part of overall property management, should avoid the need to repeat stages 1 and 2. Warrens can be fumigated with chloropicrin, or car exhaust gas. Understanding the biology and behaviour of feral rabbits is a key to their control. It presents very useful background information, outlines a four step approach to rabbit action (Assessing the problem, Planning, Control, and Monitoring), and provides guides to help with each step. These diseases were brought to Australia as biological controls for rabbits and they now occur naturally throughout much of the rabbits range.
