The Australian anti-rabbit fence should start from the first European immigration fleet that arrived in Australia. Before 1788, the ancient Australian continent could not see the rabbits. That is to say, for Australia, the rabbits were properly outside. Species. The five rabbits that came with the first batch of European immigrants opened up the history of rabbits in Australia.
At first, the rabbit was Being raised as food has not had a major impact for decades. Later, in 1859, a buddy named Thomas Austin released 24 hares in his own estate in Victoria. This buddy was an avid hunter in the UK, and he had nothing to do with a rabbit. No rabbit can be beaten, which can ruin him. In order to satisfy this little hobby of his own, he wrote to his nephew in the UK to send a rabbit and other wild animals to cultivate him for hunting. These include 12 gray rabbits, 5 hares, and 72 sparrows. However, his nephew did not raise enough gray rabbits, and he used the rabbit to make up the shortage. Since then, other manor farms have followed suit, releasing more rabbits. Two years later, Thomas found that the situation was not good and things were moving out of control. By 1865, he had hunted 20,000 rabbits on his farm, and at least 10,000 live on the farm. Moreover, the rabbits are never satisfied with his farm and have already extended their homes to hundreds of kilometers. And why the rabbits released by Thomas are so well adapted in Australia, there is a saying that these rabbits come from three different varieties, and their offspring mixed rabbits are more adapted to the Australian environment, laying the foundation for the future of rabbits.
The breeding of rabbits is like this: a female rabbit can give birth 4 to 5 times a year, up to 8 times. Each nest has an average of 4 to 5 bunny rabbits, and the bunny is only three or four months old and begins to give birth. With a year's work, a pair of rabbits can grow to more than 100. So the number of rabbits is exploding. They burrowed around and had an amazing amount of food. The food of nine rabbits was equivalent to a sheep. They eat everything when they are good, and they even lighten grass roots and bark when they are in a drought, which greatly affects the roots of Australian livestock. In order to eliminate the rabbit, people tried their best. In the early days, people mobilized manpower and dog power, and smoked and burrowed the rabbit out of the nest. Later, there was a poisoning method, deep cultivation, a narrow coulter, and the rabbit was "cultivated" in the nest. . There is also a blasting method, which is a gas tank and a pipe, which breaks the pipe into the rabbit hole, turns on the gas, and explodes.
The anti-rabbit fence introduced here is established in this context as an early anti-rabbit means. The isolation fence in Western Australia, known in the early days as an anti-rabbit fence, a fence or a fence, was built in 1901 and completed in 1907. Its main function is to prevent agricultural diseases such as rabbits from the east. The creature enters or influences the western pastoral area.
As shown in the figure, the entire fence consists of three fences: the first fence runs from south to north across the state, the second fence is smaller and more west, and the third fence is the smallest and east-west.
The entire fence took six years to complete, and the three fences were connected together for a total length of 3,256 kilometers, at a cost of $250 per kilometer at the time. The No. 1 fence was the longest leak-free fence in the world in 1907 when it was built.
