Warren destruction by ripping is used to minimise the impact of the introduced European rabbit (Oryctolagus cuniculus) on agricultural production and the environment. Other rabbit control methods include poisoning, warren destruction using explosives, warren fumigation, surface harbour removal, shooting, trapping, exclusion fencing and biological control with rabbit haemorrhagic disease (RHD) and myxomatosis.

In many areas of Australia, rabbits depend on warrens for shelter from climatic extremes, predator avoidance and also for successful breeding. Warrens are destroyed using ripping or, in rocky or inaccessible areas, explosives. Since rabbits do not readily dig new warrens, rabbit populations do not persist in areas where warrens are effectively destroyed and re-colonisation is made less likely.

Warrens are destroyed using a tractor or bulldozer fitted with single or multiple-tined rippers. The technique used will vary depending on local conditions such as soil type, position of warrens and type of equipment available. Ripping will be more humane when the number of rabbits in the warren is low and when powerful machinery is used to achieve complete disintegration of the warren, so that the rabbits are killed quickly. Because ripping gives long term management of rabbit populations the need for repeated control operations is reduced.

This National Standard Operating Procedure (NATSOP) is a guide only; it does not replace or override the legislation that applies in the relevant state or territory jurisdiction. The NATSOP should only be used subject to the applicable legal requirements (including OH&S) operating in the relevant jurisdiction.

Rabbits are one of the most destructive invasive species in Australia. This video highlights things you should know when considering rabbit warren ripping as part of your pest animal control activities.

Warren ripping and harbour destruction

How to rip etc

Video taken during Moorabool Landcare Network and the Rabbit Action Group field day to promote community based rabbit control showing how to bulldoze rabbit warrens.

This video shows how to control rabbits using warren ripping and harbour destruction. The video was produced so that woolgrowers can get the best result from the release of a strain of rabbit calicivirus new to Australia – RHDV1 K5 – in March 2017.

Following the release of RHDV1 K5 there is a need to continue with more conventional control methods, such as warren ripping and harbour destruction, which will help inhibit rabbits’ ability to re-colonise. This video is part of the Rabbit Control Video Series 2017 prepared with funding from AWI. www.wool.com/rabbits

If correctly and appropriately undertaken, the destruction of rabbit warrens, or the modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits. Although many rabbits may live and shelter above-ground (under bushes, in scrub), destruction of warrens, where they occur, can improve the overall effectiveness of rabbit control programs. If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can also help, particularly in semi-urban areas or on smallholdings.

The Victorian Rabbit Action Network (VRAN) have developed a 7 minute video about warren modification (commonly known as ripping).

On the video our VRAN Mentors, Tim Bloomfield & Brad Spear talk about the equipment used, where to use it and what you need to know before you start a program.

European rabbits (Oryctolagus cuniculus) are a serious invasive pest in Australia. Rabbits cause millions of dollars in damage to crops annually and, even at very low numbers, cause major impacts to the natural environment.

Once established in rural areas rabbits can cause extensive damage to crops, pastures and native vegetation and are difficult to control, requiring constant landholder action to manage. Rabbits construct burrows that enable them to survive a wide range of environmental conditions. They adapt to a wide range of food types and their ability to graze plants to ground level contributes to the enormous damage they cause. It is the legal responsibility of the land owner to control rabbits on their property, and penalties can be imposed for failing to do so under the Natural Resources Management Act 2004.

In 1859 when Thomas Austin released 24 wild rabbits on his Geelong property, he could not have foreseen that they would breed so prolifically and spread across the southern parts of the continent. Each year rabbits cause an estimated $600 million worth of damage to agriculture. 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. Even landholders not growing crops are still legally obliged to control rabbits to protect their neighbours’ land from the impact of rabbits.

Rabbits, foxes and feral pigs pose a major threat to our environment and agricultural production.

This video series describes why pest control programs are important in Victoria and introduces you to how collaborating with neighbours and using a variety of strategic control methods can turn this threat around.

Pests are animals causing harm or significant disturbance in areas where they are not wanted. They often have the ability to flourish if left unmanaged in suitable environments. Physical, chemical and biological control options are available to variously cull, inhibit breeding or exclude pests from priority areas. It is rare that a single control measure will be completely successful. Even very effective biological controls require support from additional control measures.

DESTROY WARRENS AND HARBOURAGE

Effective rabbit destruction often calls for a carefully worked out control programme consisting of poisoning, fumigating and warren and harbourage destruction. Possibly the most effective means of not only controlling rabbits but ultimately eradicating them from holdings is the destruction of warrens and harbourage.
