Calici helps Mulgara recovery

Reduced rabbit populations since the introduction of the Calici virus are a factor in the recovery of the Crest-tailed Mulgara. Thought to be extinct in NSW, Mulgara have been found in Sturt National Park. Reductions in rabbit populations have been linked with increased ground cover, benefiting the species. For more information, see the University of […]

Myxo helps Calici virus

Wild rabbits exposed to Myxomatosis are more susceptible to RHDV (Calici virus), compared to rabbits without prior exposure. That is the conclusion of researchers looking at eighteen years of data from a continuously monitored site at Turretfield, South Australia. Dr Louise Barnett from Flinders University presented the findings at a recent annual general meeting of […]

K5 effective in Lincoln National Park

The K5 strain of RHDV1 reduced wild rabbit numbers by 80% in the Lincoln National Park on SA’s Eyre Peninsula. For more information, see the article in the Port Lincoln Times. Photo from: Natural Resources EP

Conservation starts with rabbit control.

Concerted efforts at rabbit control by the Trust for Nature on their Ned’s Corner property are paying off. The Trust purchased the property west of Mildura fifteen years ago and has been targeting rabbits with a variety of control measures, including spreading RHDV-K5. Land that was once eroded by rabbits is now regenerating – more […]

The arms race continues – myxoma vs wild rabbits

The myxoma virus found in Australia has evolved to better suppress the immune system of rabbits, according to a team of Australian and American researchers. Rabbits with a weakened immune system will also be more vulnerable to other diseases. The team, led by Peter Kerr from the University of Sydney and CSIRO, concluded the myxoma […]

Additional rabbit bio-control feasibility to be studied.

Plans are afoot to investigate the potential to add two parasites to the armoury in the battle against wild rabbits. Eimeria intestinalis and Eimeria flavescens are infectious rabbit parasites that have been detected in south west WA, but not anywhere else on mainland Australia. If verified this may be due to a unique rabbit introduction […]

Enlisting flies to track the spread of RHDV

RFA has funded a novel project to help track the spread of rabbit viruses across Australia. It is now accepted that flies are a vector for the transmission of RHDV, thanks in part to former research by Amy Ianella which was also supported by RFA. Research has also shown that flies could be used as […]

Calici helps threatened plains mouse

The spread of the Calici virus (RHDV) has been cited as a contributor to the recovery of the native Plains Mouse (pseudomys australis). Katherine Tuft, Manager of Arid Recovery (a conservation reserve in outback SA), has reported high numbers of the native mice. “We think that a combination of good rainy years and the knockdown […]

Calici virus K5 confirmed in all mainland States

The release of RHDV1-K5 across Australia has been hailed an early success, with wild rabbit deaths due to the virus now confirmed in all mainland States. Researchers are now waiting to see how effectively the virus is spread by natural vectors like flies, and if the immediate success will translate into dramatic drops in rabbit numbers, before calling the release ‘truly […]

K5 spreads in Victoria

Feral rabbits are beginning to die from RHDV1-K5 in Victoria, following the release of the virus at trial sites. Rabbits with the K5 calici strain have been detected near release sites at Tanybryn and Kaniva. For more information see the ABC News Report.
