Sharp T & Saunders G 2005, Humane Pest Control: Codes of Practice and Standard Operating Procedures. Areas that rabbits use for harbourage/refuge include rock piles, deadfall timber and stumps, old buildings and abandoned farm machinery. If this is not possible you must stop them causing damage to adjoining crops by putting up rabbit proof fencing. Do not dog, trap, shoot or otherwise disturb the rabbits in an area for several weeks before starting a baiting program. It is best to use dogs to force surface rabbits into warrens before the start of ripping. Using carrots, 3 free feeds at 2 to 3 day intervals are best. Various methods in the 20th century have been attempted to control the Australian rabbit population. 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. Australia's biocontrol programs using Myxoma virus in 1950 and the Rabbit Calicivirus in 1995 have been extremely successful in drastically reducing pest rabbit numbers in Australia at a landscape scale. Other rabbit control methods include poisoning with 1080, warren destruction, warren fumigation, surface harbour removal, shooting, trapping, exclusion fencing and biological control with rabbit haemorrhagic disease virus (RHDV) and myxomatosis. Carrots are the preferred feed material for rabbits, but oats and pellets may be used. Identify other parties including Landcare and the Wimmera CMA, Glenelg Hopkins CMA, Vic Roads and DEPI who have previously conducted treatments. Learn about measures in place to control their spread. Several types of 1080 (sodium fluoroacetate) rabbit bait is available. Before deciding on control strategies, monitor rabbit populations using daytime observations and spotlight counts. 4. A population of 24 rabbits released near Geelong in 1859 to be hunted for sport. The release was highly successful, as an estimated 90–99 percent of the rabbit population in Australia was wiped out. Two broad rabbit control strategies are applied to rural land in NSW: the combination of poisons and harbour destruction in eastern areas with cooler climates, and extensive harbour destruction where ground conditions are suitable in western areas. 7 June 2018 – 2 new RHDV2 cases confirmed . Other rabbit harbour includes blackberry, lantana, fallen logs, farm refuse, old machinery and rock piles. Read more about management and control of European hares.

Dogs are highly susceptible to 1080 poison and will readily eat carrots, pellet baits and carcasses of dead rabbits. Rabbits may also live among surface shelter, such as dense vegetation and weeds. While myxomatosis depresses rabbit numbers, the percentage killed is usually too low to achieve a significant reduction in their impacts. During these trials the virus escaped via an insect vector and spread rapidly. This is the first time in 20 years that a new rabbit biocontrol agent has been released into Australia. Recommended control measures include: trapping; shooting; exclusion fencing; repellents. The aim of warren ripping is to simultaneously destroy the structure of the warren and kill all of the rabbits. Rabbits do not readily dig new warrens, so destruction of warrens greatly inhibits resurgence and re-colonisation of treated areas. More revealing checks can be made late in the day or at night by spotlighting when rabbits are active and more observable. Rabbit grazing of emerging crops can result in yield loses up to 100%. Trapping should only be used to control the last few rabbits, and should not be relied on to control medium to high density rabbit populations. Rabbit … 6. Set clear, attainable objectives for control work, taking account of available financial and physical resources. Use of cage traps or exclusion may be the only viable options for urban landholders. 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. From releasing rabbit-borne diseases (which proved somewhat successful in the beginning) to chicken cholera a lot of things were tried. The key to success is persistence. Updates. They released rabbits infected with myxoma—a rabbit-specific virus —into southeastern Australia.

All the entrances to a warren need to be treated at once, to make trapping effective. Rabbit activity is usually indicated by scratchings, dung heaps and active burrows or warrens. When rabbit densities are very low, advanced control methods such as shooting, trapping, fumigation and harbour destruction make use of previous control inputs to keep rabbit numbers low in the longer term. Warren ripping is highly target specific, and can be successfully employed during the breeding season (when poisoning programs are less effective). In the rangelands, where the rabbit is … 1080 and Pindone are toxins registered for the control of rabbits.

Rabbit populations all over Australia are increasing as these pests build resistance to rabbit calici disease and myxomatosis. The success of rabbit control should be determined more by how many rabbits remain than by how many rabbits have been removed. Pindone has an antidote (vitamin K1) and is safer to use in closer settled areas. Permission will usually be required before remnant or roadside vegetation can be cleared. Soft-jawed spring traps and mesh barrel traps may be used to remove rabbits. European rabbits were introduced to Australia in the 18th century with the First Fleet and eventually became widespread. Rabbits have found conditions in Australia to be ideal. If rabbit density is low the objective is to reduce the population further so that it cannot recover quickly. … Rabbits are one of Australia’s major agricultural and environmental pest animals, having cost between $600 million and $1 billion annually before the introduction of rabbit calicivirus disease in 1995. The best time is usually during mid to late summer. Myxomatosis virus was introduced to rabbits in Australia in 1950, initially giving a very high level of control of populations. Sometimes it will not be possible to use poison but other methods are available (for example, fumigation, ripping. It can sometimes be used near settlements where pets might be at risk from 1080, because unlike 1080, an antidote is available for pindone. This is particularly important in areas where rabbits have previously been a problem. It will rarely be effective in controlling medium to high density rabbit populations. Map those treatments 5. They resolved to build three rabbit-proof fences in hopes of protecting Western Australia’s pastoral lands. Each year rabbits cause an estimated $600 million worth of damage to agriculture. The release of … One rabbit is one too many. Breeding may occur during most times of the year, but usually follows milder seasons when conditions are conducive to pasture growth. It took them six years, but by 1907, more than 2,000 miles of fences crossed the continent. District-wide campaigns can reduce the problem of re-infestation by covering a large area.

However, this was unsuccessful and an integrated rabbit control program was undertaken in early 2009 at Majura Nature Reserve, Watson … RHDV should not be introduced while myxomatosis is active in rabbits. In the 1950s, the government turned to biocontrol. A shortened version of the URL, helpful when communicating the URL over email or verbally. Barrel traps are placed in the warren entrances and have a one way flap to capture animals that enter. Rabbits that recover from an attack of myxomatosis are generally immune for life. Within 50 years rabbits had spread throughout the most of the continent with devastating impact on indigenous flora and fauna. The department recommends integrated pest management using all available control measures implemented in a coordinated manner at a landscape scale. Wine producer Mary Smith spends about $1,000 a year trying to control wild rabbits on her vineyard in the Ferguson Valley in WA's South West region. Fumigation is the best method to use when a few rabbits live in widely scattered warrens or inaccessible areas. Best control is achieved in late summer when rabbit numbers are decreasing and feed is limited. However, pindone poses a risk to native animals including kangaroos, birds of prey and perhaps bandicoots. RHDV or Pindone are the preferred control options for larger areas. They also cause serious erosion problems, prevent native vegetation from regenerating, attack domestic gardens and undermine farm sheds and other buildings. In WA European rabbits (Oryctolagus cuniculus) are declared pests of agriculture under the Biosecurity and Agriculture Management Act 2007 and as such, landholders are required to control rabbits on their properties. Follow up control is usually achieved by fumigation and harbour destruction. 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. The warren provides shelter and protection for rabbits, to avoid extremes of weather and predators. However, these Australian experiments are a clear example of how we can’t control nature.
