how does the european rabbit affect the ecosystem in australia

quoted in Williams K, Parer, Coman B, Burley J & Braysher M (1995), Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO, Parker, B. S. and Bults, H.G. Important external parasites on rabbits in Australia include the introduced European and Spanish rabbit fleas, which are important vectors in the spread of myxomatosis. Livestock industries suffer most direct economic loss at present, but grain and horticultural crops, forestry and carbon plantings can all be affected. When threatened rabbits will crouch down and freeze or try to sneak away. As they journey onward, the rabbit grazes the shrubs and grasses … trapper, shooter), Government agency employee (local, state, national), Aquatic environments (including irrigation), overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields, competing with native animals and domestic livestock for food and shelter, increasing grazing pressure and lowering the land’s carrying capacity, building warrens, causing land degradation and erosion, preventing or inhibiting the regeneration of native shrubs and trees by grazing, acting as a food source for introduced predators, which can lead to increased lamb losses and disease prevalence, and a decrease in small mammal diversity. Figure 4: Workers process rabbit carcasses at a farmed rabbit processing facility. The farmed rabbit industry now dominates the supply of rabbits for domestic and overseas consumption, leading to a steady decline in the commercial harvest of wild rabbits9. (1987). 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. 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). Australian Wool Corporation. This information has been prepared with care but it is provided “as is”, without warranty of any kind, to the extent permitted by law. Journal of Zoology, London 229: 581–607. Image: Australian Broadcasting Commission. It was estimated that reduced rabbit populations as a result of RHDV would increase agricultural production by $600 million annually, including about $300 million for the wool sector, $150 million for cattle, $80 million for cropping and $70 million for sheep meat17. Gong, W., Sinden, J., Braysher, M. and Jones, R. (2009). The impact of rabbits (in combination with kangaroos) in rangeland national parks have resulted in native plants and animals being in poor condition with little chance of regeneration. This will inevitably end up having unforeseeable effects on local ecosystems as rabbits and other animals migrate toward cooler climates. In Australia, European rabbits have major impacts on agricultural productivity and the environment. Currently, more than 200 millio… Their spread may have been enhanced through the emergence of strong crossbreeds. 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. Angus & Robertson : Sydney. Over three-quarters of the State is inhabited by feral European rabbits. It has been widely introduced elsewhere often with devastating effects on local biodiversity. Rabbits prefer deep, well-drained soils (sands and light loams) which are often found on the most productive agricultural land. In Queensland, Australia, it’s illegal to own a pet rabbit unless you’re a magician. Mating can recur immediately after giving birth. FactSheet. The underside of the rabbits are completely white with all color variations. (1977). 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. Just 7 years later, 14,253 rabbits were shot on Barwon Park. Powered by the Centre for Invasive Species Solutions, View our best practice community engagement information hub ‘Community Invasives Action‘ to enhance community involvement in your invasive species management programs. However, they can also spread weeds and permanently damage native seedlings in the process2,16. Rabbits are highly selective grazers, with a preference for plants or parts of plants with the highest nutritional content. The impact of rabbits on the Australian environment has been disastrous and currently there are at least 304 Australian threatened species that may be adversely affected by competition and land degradation by rabbits. Parer, I. Rabbits also affect revegetation and soil erosion reclamation projects by feeding on newly planted vegetation or burrowing. Rabbits selectively feed on certain species of plants at critical stages of development such as seeding and seedling establishment. Fallen timber or logs, rocks, dense thickets of native scrub or woody weeds and heaps of debris create ideal shelter for rabbits. 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. They can graze plants to ground level, preventing regeneration and limiting seedling establishment1. Effective rabbit management on a property near Colac has allowed an increase from 1.75 DSE (dry sheep equivalent) to 7.75 DSE over a 5-year period. The warren is the key to the success of rabbits in Australia. This was only 22 years after their introduction to Australia and only 6 years after they were declared pest animals in South Australia. Ecological changes associated with high rabbit numbers have been blamed for the disappearance of the greater bilby Macrotis lagotis and the pig-footed bandicoot Chaeropus ecaudatus as well as putting many other species under stress. European rabbits (Oryctolagus cuniculus) were introduced to Australia in the 18th century with the First Fleet and eventually became widespread. PestSmart is managed through the Centre for Invasive Species Solutions (CISS) The Story of Pests on the Land in Australia. Map of extinction intensity in Australia 2. (2007). In 1952, the production increase following the spread of myxomatosis was worth an additional $68 million and in 1953 the increase in Australia's wool clip was estimated at 30 million kgs. It is believed that climate change is going to affect the current territory of at least ⅔ of all species of rabbit by 2100. Rabbits also will climb fences and they have been known to climb trees up to five meters. These diseases were brought to Australia as biological controls for rabbits and they now occur naturally throughout much of the rabbits range. Low-density rabbit populations can cause significant damage to native plants and pastures, suggesting there might be no ‘safe’ level of rabbit density16 (Figure 2). European wild rabbit in Australia ... Western Australia. (1969). 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. Stead, D.G. 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. Grazing competition between sheep and rabbits can affect wool production by reducing the quality and amount of wool produced per sheep. The overall loss caused by rabbits to agriculture and horticulture in Australia was recently estimated to be about $206 million per year11. The hare is larger, has longer black-tipped ears, longer hind legs, move differently and can run faster. In 1859, a farmer introduced 24 grey rabbits to remind him of home. Fleming PJS, Croft JD and Nichol HI (2002). NSW Department of Primary Industries (DPI, 2007). Australia contains eight of the fourteen ecosystem that exist. It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and has caused many problems within the environment and ecosystems. John Wiley, London. Rabbits have long hind legs and short front legs. Vere DT, Jones RE and Saunders GR (2004). Where a land owner is served with a control notice, such as a Directions Notice or Land Management Notice, in accordance with the Catchment and Land Protection Act 1994, the land owner must comply with the specific requirements of that notice including undertaking the required measures listed in that notice during the stipulated time frame. The adult coats are typically gray-brown, but range from sandy color to black or dark gray. Consequently, competition and land degradation caused by rabbits has been listed as a key threatening process to threatened species conservation under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). 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). However, cats and foxes also use rabbit warrens for shelter and dens for their young, thus helping these predators to persist in hot, arid areas3. Myers, K., Parer, I. and Richardson, B.J. The European rabbit (Oryctolagus cuniculus) is an introduced species, which was first brought to Australia with the First Fleet in 1788 as domesticated livestock. Rabbits also eat and disperse viable native plant seeds, performing an important function in the ecosystem3. The European Rabbit is a species of rabbit native to southern Europe. Ethology 75:197–210 CrossRef Google Scholar Delibes M, Hiraldo F (1981) The rabbit as prey in the Iberian Mediterranean ecosystem. Image: Australian Antarctic Division. At large warrens or where there are dense populations, different social groups may share a common warren or feeding area. The views and opinions expressed in this publication are those of the authors and do not necessarily reflect those of the institutions the authors work for or those who funded the creation of this document. In the first month, the protected area supported 38 sheep each day, compared to 12 on the unprotected area. Efficacy, Cost and Benefit of Conventional Rabbit Control. Figure 2: Browsing damage caused by rabbits. Rabbits form extensive burrows or warrens for shelter. and received funding from the Australian Government to undertake this website upgrade. Group living in the European rabbit (Oryctolagus cuniculus): mutual benefit or resource localisation. Figure 3: Vegetation degradation and erosion damage caused by rabbits on world heritage-listed Macquarie Island. Another rabbit virus, known as VHD (Viral Haemorrhagic Disease) and RCV (Rabbit Calicivirus) has also broken out in many countries. We reviewed the role of European rabbits (Oryctolagus cun … Rabbits prefer to live in areas with short grasses, including natural grasslands and rural pastures. This study shows that European rabbit warrens have a positive influence on lizard density and diversity, and confirms the role of rabbits as ecosystem engineers. (1975) ) quoted in Williams K, Parer, Coman B, Burley J & Braysher M (1995), Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO. 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. The rate of rabbit invasion varied from 10 to 15 kilometres per year in wet forested country to over 100 kilometres per year in the rangelands. Australia’s temperate conditions — general lack of seasons and little cold — and huge swaths of natural low vegetation make for an ideal rabbit home, so much so that the perennially-breeding creatures destroyed two million acres of floral lands in Victoria before they were even spotted in another state. The virus affects rabbits that haven’t previously been exposed to it, damaging the animal’s liver and spleen and eventually causing its death. 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. In Australia , the rabbit competes for food and shelter with native animals such as the wombat, the bilby, the burrowing bettong and the bandicoot, and therefore has contributed to the decline of these native species. The return on investment in rabbit control is greater when high-value commodities or resources are protected from damage. Long-term effects of warren ripping for rabbit control in semi-arid South Australia. Cowan, D.P. In temperate regions rabbits can occur almost anywhere except in dense forests, on black soil plains or above 1500m. The role of the rabbit as a keystone species in Iberian ecosystems The European wild rabbit plays a major role both directly and indirectly in ecosystem services in south-west Europe and is also of economic importance as a game species (Fa et al., 1999; Angulo & Villafuerte, 2004). 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). Department of Environment, Water, Heritage and the Arts (DEWHA, 2008). The European rabbit can be identified by long floppy ears, short tail, and long jumping gait. Just before the breeding season in late Autumn and early winter a second dispersal occurs with sub-adult males moving to new areas. Although biological controls (myxoma virus and rabbit haemorrhagic disease virus, or RHDV) have provided ongoing rabbit control for over 60 years with little cost10, they have not eliminated the problem4. While the initial costs of rabbit control can be high (eg warren ripping costs are about $10–$20 per warren10), the benefits can be long term. It not only provides protection from predators but also protection from environmental extremes. By the 1920s, rabbits had colonised most of the southern half of Australia and were present in extremely high numbers. The authors of these documents have taken care to validate the accuracy of the information at the time of writing. Caughley, G.C. Wild dog, dingo-dog hybrids (feral or wild), classification of invasive animals in Victoria. Wild rabbits were introduced to Australia in the mid to late 1800s at places such as: In 1859, approximately 7 rabbits were released at Barwon Park near Geelong. Rabbits have high rates of dispersal that is generally broken down into 2 dispersal events. Croft JD, Fleming PJS and Van de Van R (2002). This is a highly infectious and lethal form of viral hepatitis that affects European rabbits. The feral European rabbit is one of the most widely distributed and abundant mammals in Australia. 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. European rabbits occur throughout Victoria except in alpine and closed forest environments. Even low numbers of rabbits can have a devastating effect on tree-planting programs or intensive horticultural operations. 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. Despite common opinion rabbits do not readily dig new warrens preferring to find an unused warren to excavate. While much of the country boasts diverse … Invasive Animals Cooperative Research Centre. Rabbits are always searching for new areas to establish. large birds of prey such as wedge-tailed eagle. (1977). Williams K, Parer I, Coman B, Burley J and Braysher M (1995). In certain areas, rabbits are in direct competition with native wildlife for food and habitat. Sociality, time and space in a sparse population of rabbits (Oryctolagus cuniculus). These erosion effects lead to off-site problems, such as reduced water quality, increased soil movement which may incur expensive repair measures. Like hares, caecotrophy (the re-ingestion of faecal material from the caecum) is a behaviour that is used by European rabbits in order to gain the maximum amount of nutrients from their food as possible. Rabbits can have considerable impacts on farm productivity and native ecosystems, leading to financial loss and environmental devastation 1 . 6. 12. Note the 45°‘secateur-like’ cuts through the twigs. Everywhere the European Rabbit travels in Australia, it brings destruction to existing ecosystems. 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. PestSmart website. Rabbits are wary of new food items and changes to their environment. In Australia rabbits inhabit a wide range of vegetation types. The population ecology of the wild rabbit Oryctolagus cuniculus (L.) in a Mediterranean-type climate in New South Wales. In addition, rabbits cause serious problems on … At the time, the man wrote: "The introduction of a few rabbits could do little harm and might provide a touch of home, in addition to a spot of hunting." The history of the rabbit in Australia demonstrates that people can be really silly. The impact of rabbits on agriculture and conservation will continue to grow, unless continuous effort is put into long-term, integrated rabbit control. 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. 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. European rabbits are generally greyish-brown in color. Wild rabbits are harvested to supply meat for the game and pet meat industries, and skins for the felt hat industry1,4 (Figure 4). Vermin and Noxious Weeds Destruction Board Bulletin No. Rabbits have unique upper teeth consisting of a pair of gnawing hypsodont teeth (which grow continuously) and a pair of peg teeth hidden behind. Rolls, E. (1969). These include deserts, tropical and subtropical regions, mediterranean woodlands, temperate forests and grasslands, montane lands and tundra. Richardson, Australian Government Publishing Service, Canberra, Vol. The Threat abatement plan released by the Australian Government Department of the Environment in January 2016 found that rabbits are a significant threat to biodiversity, affecting 304 nationally threatened plant and animal species. (Australian Government Publishing Service: Canberra). About 16 rabbits/ha is equivalent to one dry sheep equivalent (DSE) or about 12 rabbits per DSE in higher-rainfall areas. Wagner, F. H. (1981) ) quoted in Williams K, Parer, Coman B, Burley J & Braysher M (1995), Managing Vertebrate Pests: Rabbits Bureau of Resource Sciences and CSIRO. Proceedings of a Symposium Held at Rusden C.A.E. (1989) Leporidae. Early last year, vets in Sydney, Australia urged owners of pet rabbits to vaccinate their animals against Rabbit Calicivirus (The Australian 2014), also known as Rabbit Hemorrhagic Disease Virus (RHDV). In the second month the protected area supported 45 sheep whereas the unprotected area could support only 7. By 1879, the South Australian and Victorian infestations had merged covering the area from Spencer Gulf to north-eastern Victoria. Each year, the approximate overall cost caused by rabbits was estimated to be $206 million. For example, if one sheep is conservatively considered the grazing equivalent of one warren of 12–16 rabbits14, a paddock containing 500 warrens is already bearing the equivalent of 500 grazing sheep, before the paddock is even stocked. Centre for Invasive Species Solutions, 2012. 917–931 in: Fauna of Australia, eds. Rabbit populations are now on the rise, potentially putting Australia’s growing carbon-offset industry and agricultural sectors at risk. Most dispersal is relatively short distance with rabbits joining adjacent social groups however movements of up to 20km have been recorded. Cooperative Research Centre for Pest Animal Control. 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. Rabbits are mostly active from late afternoon to the early morning. Analysis of Vertebrate Populations. Juvenile rabbits moult at 3 months of age and frequently have a white star on their forehead, which they lose when they moult. Competition and land degradation by rabbits is listed as a key threatening process in Australia4. Rabbit damage to native vegetation can seriously disadvantage native animals. They have caused a lot of damages on crops and also destroyed and killed young trees and plants. It takes less than one rabbit per hectare to prevent the successful regeneration of many native trees and shrubs. Rabbits mostly feed in areas of short vegetation within 300m of the warren but will travel further when food or water is scarce. The European rabbit is a small mammal native to southwestern Europe and to northwest Africa. Rabbit warrens provide refuge for some native species such as echidnas and large reptiles3. Gong W, Sinden J, Braysher M and Jones R (2009). Pp. In some instances the impact created by rabbits on vegetation is often replaced with noxious or unpalatable weed species. European rabbits hurt Australia's native species and crops. Williamson, Chapman & Hall (1996) Biological Invasions. They have long ears and large slightly protruding eyes placed to the sides of the head that gives them panoramic vision. It causes severe damage to the natural environment and to agriculture. 1B. It causes severe damage to the natural environment and to agriculture. Rabbits form social groups that have a complicated social structure with dominant males typically defending a territory to gain mating rights to the females. However, they are not found in Southern South America, West Indies, Madagascar, and the majority of the islands Southeast of Asia. biosecurity officer, ranger), Management professional (e.g. Hotspots are said to be experiencing a major loss of habitat, but an added risk could be the decline of some species having a special role in ecological relationships of the system. Removal or loss of vegetation makes soils prone to wind and water erosion (Figure 3), which on farms can lead to reduced soil fertility and siltation of dams1,3. For example, rabbit damage to high-value crops such as canola might be more financially devastating than damage to lower-value crops (eg lupins, barley), which generate lower returns per hectare12 (Figure 1).
