Because for the past 150 years, rabbits have caused immense ecological damage to Australia. The male rabbit is called a 'buck', the female rabbit is called a 'doe' and her young are called 'kittens'. Image: Australian Antarctic Division. It takes less than one rabbit per hectare to prevent the successful regeneration of many native trees and shrubs16, which are vital for biodiversity and farm productivity. Competition and land degradation by rabbits is listed as a key threatening process in Australia4. Image: Australian Broadcasting Commission. (1993). It not only provides protection from predators but also protection from environmental extremes. Research in semi-arid sites has shown that rabbit densities of 0.5 per hectare (1 rabbit per 2 hectares) can severely damage some plant species and it's possible there may be no safe rabbit density for some tree and shrub seedlings. Brunner, H., Stevens P, L., Backholer J. R. (1980) Introduced Mammals in Victoria. July 1980. Economic and environmental impacts of rabbits in Australia. Although these trades have suffered as a result of fewer rabbits post-RHDV, the benefits of rabbit control to agriculture and the environment far outweigh these losses17. FactSheet. Vermin and Noxious Weeds Destruction Board Bulletin No. The cost per rabbit also varies depending on the value of the affected commodity (eg crop type). Rabbits also cause damage to grain crops and have significantly reduced crop yields in some areas. 917–931 in: Fauna of Australia, eds.

ACIL Economics and Policy Pty Ltd (1996). Rabbits also will climb fences and they have been known to climb trees up to five meters. The warren is the key to the success of rabbits in Australia. But in Australia (and many small islands where it has been introduced), the rabbit, virtually unchecked by local predators, decimates plants, affects soil composition, and changes entire ecosystems. Some viral strains also affect hares and cottontail rabbits. While much of the country boasts diverse … Department of Primary Industries and Fisheries Queensland (DPI&F, 2008). Fallen timber or logs, rocks, dense thickets of native scrub or woody weeds and heaps of debris create ideal shelter for rabbits. (1967) ) quoted in Williams K, Parer, Coman B, Burley J & Braysher M (1995), Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO, Pickard (1995), in Williams K, Parer, Coman B, Burley J & Braysher M, Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO. Rabbit meat is considered a high-value gourmet product, although the market price depends on consumer acceptance and demand4. Note the 45°‘secateur-like’ cuts through the twigs. In only 3 years of high rabbit densities, the cover of subterranean clover has been shown to reduce from 75 per cent to 20%. Sociality, time and space in a sparse population of rabbits (Oryctolagus cuniculus). Because of the high fecundity of rabbits and the damage likely to be caused by subsequent generations7, on-ground management actions — in conjunction with biocontrol — are expected to provide substantial benefits to primary production and biodiversity. Invasive Animals Cooperative Research Centre. In a trial in south-western Victoria, 2 areas each a hectare in size, 1 protected against rabbits, the other unprotected were studied over a 2-month period. Angus & Robertson : Sydney. The European rabbit is a small mammal native to southwestern Europe and to northwest Africa. Rabbits can cause damage by: All of these impacts eventually lead to higher management costs7, loss of productivity6,8, and huge financial losses for Australia’s farmers9, as well as other land managers (eg national parks)7. The impact of rabbits on agriculture and conservation will continue to grow, unless continuous effort is put into long-term, integrated rabbit control. European wild rabbit in Australia ... Western Australia. In the second month the protected area supported 45 sheep whereas the unprotected area could support only 7. Recent estimates have valued the cumulative benefit of myxomatosis and RHDV to Australia’s pastoral industries at about $96 billion over the last 60 years10. biosecurity officer, ranger), Management professional (e.g. Rabbit damage and control costs at the property level vary depending on the land use or enterprise, climate and rainfall, and control methods used1, 5 (see table). This virus, a benign parasite of the Brazilian forest rabbit, was highly lethal for European rabbits. Important external parasites on rabbits in Australia include the introduced European and Spanish rabbit fleas, which are important vectors in the spread of myxomatosis. Williams K, Parer I, Coman B, Burley J and Braysher M (1995). Stodart, E. and Parer, I. Rabbits are always searching for new areas to establish. Efficacy, Cost and Benefit of Conventional Rabbit Control. Ph.D. Thesis, University of Adelaide. If this fails rabbits will sprint for the warren or cover with the white underside of the tail showing as a visual warning to other rabbits. https://pestsmart.org.au/toolkit-resource/economic-and-environmental-impacts-of-rabbits-in-australia, Decision Support Systems for rabbit management, Trapping of rabbits using padded-jaw traps, Overview of poison baiting for rabbit control, Ground baiting of rabbits with sodium fluoroacetate (1080), Aerial baiting of rabbits with sodium fluroacetate (1080), Bait delivery of Rabbit Haemorrhagic Disease Virus (RHDV1) K5 strain, Overview of rabbit warren and harbour destruction, Rabbit warren destruction using explosives, How to report rabbit disease and dead rabbits, Key facts about rabbit biocontrol in Australia, Frequently asked questions about RHDV1 K5, Centre for Invasive Species Solutions (CISS), How to improve and enhance my management program, Who to connect with prior to taking action, Public land manager (e.g. Rabbits were sometimes stopped by fences, but in plague proportions, there were so many rabbits piled up by the fences, that the rabbits acted as a ladder for others that simply walked over the fence. Rabbits are highly selective grazers, with a preference for plants or parts of plants with the highest nutritional content. It is believed that climate change is going to affect the current territory of at least ⅔ of all species of rabbit by 2100. During and immediately after the breeding season 60% of young male and female rabbits disperse from the breeding warren seeking unused burrows and safe above ground harbour. Rabbits are a commercial resource that provides employment and income, mainly in rural areas9. Rabbits can have considerable impacts on farm productivity and native ecosystems, leading to financial loss and environmental devastation 1 . They have adapted to Australia's diverse environments, establishing themselves in farmland, deserts, grasslands and wet coastal plains, and causing havoc to native flora and fauna. (1987). Currently, more than 200 millio… In central New South Wales, a paddock experiment found that as rabbit density increased, pasture productivity decreased6. Long-term effects of warren ripping for rabbit control in semi-arid South Australia. This will inevitably end up having unforeseeable effects on local ecosystems as rabbits and other animals migrate toward cooler climates. In forestry plantations, damage from browsing rabbits can equate to one year’s loss of growth — up to $800/ha at clear-felling. Department of Environment, Water, Heritage and the Arts (DEWHA, 2008). Before RHDV became established, the value of the wild rabbit industry was estimated at about $10 million per year17. European rabbits hurt Australia's native species and crops. They have caused a lot of damages on crops and also destroyed and killed young trees and plants. Rabbits are mostly active from late afternoon to the early morning. Grazing competition between sheep and rabbits can affect wool production by reducing the quality and amount of wool produced per sheep. Proceedings of a Symposium Held at Rusden C.A.E. The European rabbit (Oryctolagus cuniculus) or coney is a species of rabbit native to southwestern Europe (including Portugal, Spain and western France) and to northwest Africa (including Morocco and Algeria). The hare is larger, has longer black-tipped ears, longer hind legs, move differently and can run faster. PestSmart website. The authors of these documents have taken care to validate the accuracy of the information at the time of writing. Rabbits selectively feed on certain species of plants at critical stages of development such as seeding and seedling establishment. These include deserts, tropical and subtropical regions, mediterranean woodlands, temperate forests and grasslands, montane lands and tundra. Rabbits have high rates of dispersal that is generally broken down into 2 dispersal events. Rabbits become sexually mature at 3 to 4 months. This double pair of upper teeth are found only in rabbits and hares and cause a very distinctive 45 degree angle cut on browsed vegetation. Parer, I. and Libke, J.A. In Australia, the most significant predators of European rabbits are the: In Australia rabbits are affected by internal parasites such as: There are two types of diseases present in Australia that are deadly to rabbits including Myxoma virus (MV) and rabbit haemorrhagic disease virus RHDV (RHDV, formerly known as calicivirus).

There are several variables in determining the direct impact of rabbits on primary production, such as the distribution and density of rabbits, and the type, level and value of production. At large warrens or where there are dense populations, different social groups may share a common warren or feeding area. The Story of Pests on the Land in Australia. The European hare is the only animal in Australia that looks similar to the rabbit. The adult coats are typically gray-brown, but range from sandy color to black or dark gray. Cowan DP (1987) Aspects of the social organisation of the European wild rabbit (Oryctolagus cuniculus). Figure 1: Damage to a canola crop caused by rabbit grazing.Image: from Wheeler et al (2002)12. Before the release of RHDV, rabbit-induced production losses in the Australian wool industry were about $130 million per year11. CSIRO Division of Wildlife and Ecology Project Report No. When close to cover rabbits will respond to threats by thumping the ground with their back legs and vocalising to warn other rabbits. By 1875, rabbits were was well established in the western districts of Victoria, in South Australia at the southern end of the Flinders Ranges and around Sydney. The European rabbit Oryctolagus cuniculus, a keystone species of Mediterranean ecosystems, is the target of several recovery and management plans throughout the Iberian Peninsula.The majority of these plans are limited in time by budget constraints and lack postintervention monitoring of population trends. Failed Rabbit Controls in Australia . Rabbit populations may sustain numbers of predators such as cats and foxes subsequently increasing pressure on native animals, particularly those in critical weight ranges below 5kg. Early introductions of European rabbits into Australia were domestic breeds that were unable to survive in the wild. Everywhere the European Rabbit travels in Australia, it brings destruction to existing ecosystems. Rabbits form social groups that have a complicated social structure with dominant males typically defending a territory to gain mating rights to the females. It quickly reduced Australia’s rabbits to a mere 5% of former numbers. (1995) in Williams K, Parer, Coman B, Burley J & Braysher M, Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO. For a wool producer, the cost of grazing competition between sheep and rabbits is a major cost typically measured in terms of dry sheep equivalents (DSEs). In 1935, it was estimated that if rabbits were eradicated the State of New South Wales alone could immediately carry another 12,000,000 sheep. Rabbits generally obtain water from green vegetation but will travel to drink if they can't obtain enough water from their diet. Stead, D.G. In Australia, European rabbits have major impacts on agricultural productivity and the environment. Rabbits have long hind legs and short front legs. Gong W, Sinden J, Braysher M and Jones R (2009). Although RHDV has effectively reduced the impact of rabbits across many parts of Australia, it is unlikely to keep populations down over the long term18,13. They have long ears and large slightly protruding eyes placed to the sides of the head that gives them panoramic vision. Cooperative Research Centre for Pest Animal Control. The European rabbit (Oryctolagus cuniculus) is an introduced species, which was first brought to Australia with the First Fleet in 1788 as domesticated livestock. Williams, C.K., (1991). Male (bucks) European rabbits weigh more and have broader heads than females (does), but the overall appearance of both sexes is v… Typically emerging about 1 to 3 hours before sunset, rabbits graze and socialise on or near the warren until dusk where they move further away. In the absence of warrens rabbits can also exist above ground where there is abundant surface harbour. and received funding from the Australian Government to undertake this website upgrade. The Mediterranean Basin is a global hotspot of biodiversity. Image: Brian Cooke. They All Ran Wild. Human activity does not deter rabbits and they may also become a problem around houses, farm buildings and other man-made structures such as water tanks. 1B. Their spread may have been enhanced through the emergence of strong crossbreeds. Rabbits typically stay above ground during the night unless disturbed. Over three-quarters of the State is inhabited by feral European rabbits. The overall loss caused by rabbits to agriculture and horticulture in Australia was recently estimated to be about $206 million per year11. Another rabbit virus, known as VHD (Viral Haemorrhagic Disease) and RCV (Rabbit Calicivirus) has also broken out in many countries. Centre for Invasive Species Solutions, 2012. Caughley, G.C. This species is an established pest animal (feral or wild populations only) in the state of Victoria. Mortality rates generally range from 70 to 100 percent. Not only do these animals affect the native flora, but they have a huge effect on the populations of other native animals. It has been estimated that at the turn of the last century the direct cost of rabbits to Australia, due to lost beef, lamb and wool production and expenditure on control measures, was $206 m… Richardson, Australian Government Publishing Service, Canberra, Vol. Currently, rabbits inhabit around 4 million square kilometres of Australia, stretching from southeast NSW to the WA wheatbelt.
