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.
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 […]
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 […]
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 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‘.
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 […]
Following the arrival of RHDV2, European wild rabbit numbers dropped to around 20% of the average over the preceding ten years, according to recently published survey data. The results come from two long-term monitoring sites in South Australia, in the Flinders Ranges and at Turretfield. If the two sites are representative of other areas and […]
The use of poisoned oats to control wild rabbits has decreased in South Australia, following the introduction of RHDV. After RHDV spread through SA in the late 1990s rabbit numbers were reduced so much that the average demand for poison decreased by about 60-70%, and a similar picture has emerged following the arrival of RHDV2. […]
‘Rabbit histories’, tracking the mortality of over 4,000 rabbits, are now available from a long-term monitoring site at Turretfield Research Centre in South Australia. For twenty years, rabbit populations on the property have been routinely estimated and sampled, providing data that is proving useful on many fronts.Blood and tissue samples provide evidence of the incidence […]
The RHDV1 K5 virus is beginning to take hold in the Otago region of New Zealand. Landholders are urged to take advantage and follow-up with secondary controls. For more information, see the article in The Country, NZ Herald. Photo: Otago Daily Times
