Virus at work on Tasman’s rabbit population
21 July 2009
Tasman residents, particularly those in the Kina Peninsula and Motueka areas, are being advised that they may see an increased number of dead rabbits over the coming months.
‘There is nothing for residents to worry about’ says Ken Wright, a Biosecurity Officer at Tasman District Council. ‘The rabbit population in the Kina Peninsula is being hit by the Rabbit Calici Virus; this was imported into New Zealand 12 years ago to help control rabbit populations. The Calici virus is specific to the European rabbit and does not cross over to any other animal species.” Ken continued.
The virus, or the carcases of those rabbits killed by the virus, offers no threat to wildlife or pets generally but there may be some risk to domestic rabbits if they come into contact with feral rabbits. Vaccination is available from local Vets if extra protection is wanted.
The Calici virus kills most rabbits in three days but some young rabbits develop immunity to it. The virus is now present throughout New Zealand and is thought to have been spread by grazing animals, predator birds and insects such as flies.
The virus is transmitted from rabbit to rabbit, is usually more prevalent in springtime, and cycles through Tasman’s rabbit population regularly. The Calici virus plays an important role in keeping rabbit populations down to manageable levels without landowners having to resort to poisons.
If you find a dead rabbit and you need to dispose of it, burying is the best option. However, the spread of the virus is likely to be improved if you can leave the dead rabbits as you find them.
