Background
The introduction of myxomatosis 50 years ago was a milestone in a formerly
hopeless battle against the wild rabbit. The economic benefits of fewer
rabbits were immediately obvious and the ecological impact of rabbits
slowly became clear.
The desire to keep
rabbit numbers low was generally maintained and indeed fuelled the development
of State rabbit control schemes, the development of efficient chemical
and mechanical control methods and the introduction of two species of
rabbit fleas from Europe to help spread the myxoma virus.
As a result of rabbit
calicivirus, rabbits are presently at low levels in many regions, and
some people believe they are no longer a problem. However even small numbers
of rabbits present a threat to conservation because they prevent regeneration
of native pastures and other vegetation in arid regions. Rabbits also
continue to support populations of important predators like foxes and
cats. Keeping rabbit numbers low also helps to insure against recurring
economic loss and the possibility that rabbits will recover their numbers
quickly if they develop resistance to rabbit calicivirus.
It can be argued that
rabbit numbers should be kept low and pushed to even lower levels if possible.
Introduction
An Australian meeting called the Rabbit Control Forum - the next 50
years was held on 25 October 2001 to discuss the future of rabbit
control in Australia.
The forum aimed to:
| |
- Review the
current rabbit situation in Australia,
|
| |
- Update stakeholders
on developing technologies for rabbit control,
|
| |
- Identify
and prioritise research for reducing agricultural and environmental
damage caused by rabbits, and
|
| |
- Consider
the best approaches for coordinating and progressing rabbit control
and research in Australia.
|
Eighty people representing
farmers, researchers, policy makers, industry and animal welfare representatives
and State and Commonwealth management agencies took part in the forum.
At the forum dinner
Professor Frank Fenner spoke about the scientific and political challenges
of introducing myxoma virus into rabbits in the 1950s. He also considered
these against the situation today where many more legislative safeguards
regulate the introduction of new biological control agents.
This forum was held
100 years after building began of the famous 3,256 km-long rabbit-proof
fence in Western Australia, and 50 years after myxomatosis was established
in rabbit populations in Australia. It was organised by the Cooperative
Research Centre for the Biological Control of Pest Animals (PAC CRC) in
conjunction with CSIRO Sustainable Ecosystems and the Bureau of Rural
Sciences.
