Wild
rabbits are popular game animals, especially in Europe. Varieties
of it are raised commercially for meat, skins, and wool, as well
as for pet trade. It is used extensively (about .5 million/year)
in medical research and for testing the safety of chemicals and
consumer products.
The
wild, domesticated rabbit has been highly successful in most places
where it has been introduced, and it is considered an agricultural
pest in many areas (especially where its natural predators have
been eliminated). They eat cultivated crops and compete with domestic
animals for forage. Millions of dollars are spent annually in countries
such as Australia, New Zealand, Britain, and the United States in
efforts to control, confine or exterminate them.
A number
of extinctions have been reported, with many other species in steep
decline, though introduced predators have undoubtedly also played
a role.
On the other hand, rabbits may provide some benefits to some native
species. Their burrowing loosens soil, which is helpful to certain
plant and animal species, and abandoned burrows provide ready-made
shelters for snakes, turtles, and other species. In addition, they
are prey for a wide variety of carnivores, including canines, felines,
and birds of prey.
In
the 1950s, myxomatosis, a virus, began wiping out the rabbit population.
When European rabbits were first exposed to the virus, the effect
was devastating; in some areas the rabbit population was virtually
wiped out. The rabbits that survived gradually became more resistant,
but this immunity weakens over time in the absence of the virus.
