How did rabbits impact Australia?
Their numbers became so large that they destroyed crops and land, leading to soil erosion. They also negatively affected agriculture and plants by overgrazing. Not only did the rabbits wreak havoc on Australian croplands, they contributed to the decline of native plant and animal species.
What are the effects of rabbits on the environment?
Rabbits can have considerable impacts on farm productivity and native ecosystems, leading to financial loss and environmental devastation 1. The community also suffers indirectly, as they might pay higher prices for rabbit-affected commodities (such as wool) 2 or bear the loss of ecosystem services at the catchment scale 3.
What are the economic impacts of rabbits in Australia?
The overall loss caused by rabbits to agriculture and horticulture in Australia was recently estimated to be about $206 million per year 11. Figure 1: Damage to a canola crop caused by rabbit grazing.
What was the impact of rabbits on Macquarie Island?
Following the eradication of feral cats in 2000, rabbits and rodents became the dominant pest species on the island. A dramatic increase in their populations caused devastating damage to the island’s vulnerable vegetation, wildlife and geology. Rabbits consumed the large, leafy megaherbs and grasses, which lacked the ability to adapt to grazing.
When did the European rabbit come to Australia?
The European rabbit ( Oryctolagus cuniculus) is an introduced species, which was first brought to Australia with the First Fleet in 1788 as domesticated livestock. Over three-quarters of the State is inhabited by feral European rabbits.
How does the rabbit affect the native wildlife?
The rabbit impacts upon native wildlife in many ways: 1. By directly competing for food and habitat the rabbit has displaced many small to medium size marsupials such as the greater bilby, Macrotis lagotis(now an endangered species), and the burrowing bettong Bettongia lesueur, (now extinct on the mainland).
Why are rabbits an introduced species in Australia?
Rabbits are one of Australia’s most visible introduced species. Australia’s native plants and animals adapted to life on an isolated continent over millions of years but since European settlement they have had to compete with a range of new animals for habitat, food and shelter.
How big is the economic impact of rabbits?
The economic impact of present day rabbit populations is not well quantified but is estimated to be in the order of 90 million dollars in lost production and about 20 million spent on control (Sloane et al.1988). 1.
