Although the hare was very successful at colonising Victoria its
populations never reached the spectacular proportions of the European
Rabbit - Oryctolagus cuniculus. One of the reasons for
this may be that rabbits are colonial animals that bear young in deep,
complex burrows while hares are relatively solitary and rear their young
in nests built in the undergrowth. Where conditions are favourable
rabbits may dig huge burrow systems which are defended by collaborative
adults. A female rabbit can reproduce several times a year at any
time conditions are favourable, the young are weaned at about one month
and females may produce litters of their own after five months. The
reproductive strategy for hares is similar although the cycle is longer
and slower, and fewer young are born in each litter. In addition
the young may be more susceptible to predation by snakes, goannas and
raptors.
Hares are less visible in the landscape than rabbits as they are
usually nocturnal while rabbits are most active at dawn and dusk (crepuscular).
But the damage created by rabbit burrows, especially in areas
susceptible to soil erosion, makes their presence even more noticeable
and is one of the major reasons that graziers came to mount destruction
campaigns against the species. Hares competed with livestock for
food but rabbits also destroyed the pasture and the soil it grew from.
The European Hare may have been less successful than the rabbit in
invading Australia but its natural geographic range is much broader.
The European Rabbit is native only to Spain and Portugal and has been
introduced to many other countries around the world by English and other
European explorers and settlers. Lepus europaeus is
native to most of continental Europe, the Middle East and central Asia.
Some biologists believe that the European Hare is a subspecies of the
similar Cape Hare, Lepus capensis, which, if true, would mean
that the species natural range also extends across much of Africa.
Australians have little trouble regarding rabbits and hares as
introduced animals. Both were clearly brought here by the English
as part of a program to make the country look and feel more like home.
The irony is that neither species is native to England. The rabbit
was introduced by the Normans during the 12th century and
although modern English wildlife books will all point this out, the
rabbit is still considered by most English people to be a natural part
of the countryside. The hare, on the other hand, is still
categorised as native to England by many modern texts even though the
current evidence is that it was probably introduced by the Romans nearly
2000 years ago.
