Resurgent RHDV K5?

Low rabbit numbers on an Eyre Peninsula property may be due to an increase in RHDV K5 during cooler months – a result anticipated by Natural Resources Officer, Ben Tucker, who coordinated the local release of the virus at trial sites last year. For more information, see the November, 2018 Stock Journal article.

Diverse genetics indicates diverse origins

Australia’s feral rabbits fall into three primary genetic lineages, with three other highly localised ones, according to a recently published research paper. The results suggest the rabbits originated from different introductions across the country, rather than a single site. The research, assisted in part by funding from the Foundation for Rabbit Free Australia, examined the […]

Virus immunity in young rabbits

CSIRO funded researchers have discovered why young rabbits are immune to RHDV1, but not RHDV2. It seems that young rabbits have a naturally heightened immune system, but RHDV2 is able to shut down the elevated immune state – whereas RHDV1 is not. For more information, see the Research Updates in Feral Flyer Issue 350 (the […]

Learning Networks spread rabbit control

The Victorian Rabbit Action Network is running a training program to help people develop local rabbit control groups, or ‘learning networks’. Participants in the 2.5 day course can apply for a $1,000 grant to support local rabbit control projects. For more information see Leadership in Rabbit Control Course.

Remarkable conservation – rabbit, rodent & cat removal

Macquarie Island’s rebirth continues following the removal of rabbits, rodents and cats. Described as one of the most remarkable stories of conservation in Australia (if not the world), the vegetation on the island is now ‘just going nuts’ and bird life is also recovering, with ‘beaches littered with wildlife’. For more information, see the ABC […]

Killing wild rabbits conserves native mammals

Ecological modellers have shown how reducing wild rabbit numbers helps maintain small native mammals. Benefits for small mammals occur when 30-40% of rabbits are removed through a mix of biological and physical controls. Higher rates of rabbit removal can lead to a decline in small mammals in the short term, but with subsequent long term […]

How to monitor Bilbies

The Martu people of the western deserts are involved in developing a bilby monitoring program, combining traditional knowledge and scientific techniques. Robust monitoring is critical to the evaluation of different management strategies, such as burning practices and the control of cats, foxes and rabbits. For more information on the project, see the Threatened Species Recovery […]

Synergistic disease dynamics

Combing 17 years of field data on wild rabbit mortality and a model of rabbit populations has provided researchers with insight to the interactions between rabbit diseases – concluding that rabbits that have survived myxomatosis are more vulnerable to RHDV than those not previously infected by myxo. The researchers suggest several factors that may influence […]

Gene drive questions

Gene drive technology (a way to spread a specific gene through a species) may have potential for feral animal control (especially in isolated pest populations), but non-technical questions are also being raised. For more information, see the ABC News article – ‘Feral science or feral solution‘.

Disease synergies aid rabbit control

Exposure of rabbits to the myxoma virus renders them less likely to survive RHDV, according to a soon to be published research paper. The research, led by Louise Barnett and assisted by RFA, shows that a combination of biological controls can have more impact than the sum of individual controls on their own. For more […]
