Rabbits are widespread throughout the Australian mainland and some islands. Their ability to burrow affords the rabbit protection from other predators but causes untold damage to the environment through the destruction of crops and soil erosion through to over grazing of native plants and commercial crops.
The rabbit’s ability to reproduce from the age of 4 months, 5 times a year, when food sources are good, places considerable strain on the environment with both native species and livestock competing for food. The economic cost to farmers and the toll on the environment is extremely high.
While biological control has been successful in controlling rabbit numbers, the rabbit’s ability to resist new strains of virus has not made this a long term solution.
