In modern times, rabbits entered Australia with human beings, and rabbits entering the wild quickly flooded because of the lack of natural enemies. So, since rabbits are flooding in Australia, why not introduce lynx, the natural enemy of rabbits?
In fact, the interests of Australia and the fact that Australian universities do not introduce lynx are due to various considerations. First of all, the lynx is not an animal suitable for introduction. Lynx itself is a medium-sized cat. Although there are many species of lynx, in fact, most of them are rare and endangered. Under such circumstances, it is doomed that lynx cannot be introduced on a large scale. In fact, this can refer to a series of domestic operations to restore extinction of Platts and Elk, thus introducing wild release. The situation of lynx doomed that Australia could not introduce a large number of lynx. If only a few dozen lynxes are introduced, it will have no effect on the already flooded rabbits. It will undoubtedly take too long to cultivate a sufficient number of lynx.
The introduction of lynx may not achieve the expected results. It is a good idea to introduce natural enemies to deal with a species troubled by Fan Li, but it should be noted that the introduced natural enemy lynx is also an exotic species to Australia. Moreover, once the lynx is released into the wild, it is very questionable whether these lynx will catch rabbits as humans think. Although lynx is the natural enemy of rabbits, you should know that lynx not only eats rabbits, but also kills other small mammals or reptiles. For example, some small marsupial jerboa in Australia may be easier to catch than rabbits, and it is likely that the number of rabbits will not be obviously controlled, and some protozoa in Australia will be threatened by lynx. This kind of thing never happened in Australia. Sugarcane toads introduced to Australia to kill pests did not feed on pests as people thought, but caused ecological disasters in Australia.
The third reason why Australia does not introduce lynx is that the effect of introducing lynx will be quite limited. The rampant spread of rabbits in Australia gives people the illusion that Australia has no natural enemies of rabbits. Actually, it's not. Australia has many natural enemies of rabbits. Rabbits belong to the bottom of the food chain in nature, and many predators feed on them. The same is true of Australia. Eagles in the sky, some monitor lizards and snakes on the ground can eat rabbits. In addition, there are wild dogs as strange as rabbits, which occupy the niche of Australian wolves and prey on rabbits. However, even with the suppression of these species, the number of rabbits can be submerged. On the one hand, rabbits have strong reproductive ability, on the other hand, rabbits are better at avoiding danger than Australian native species. In other words, rabbits are harder to catch. So even if the lynx is introduced, it is likely to feed on other small animals that are better caught.
To sum up, although lynx is the natural enemy of rabbits, it is not suitable for blind introduction in Australia. The biggest possibility is that the number of rabbits has no effect, while other Australian native species will be invaded by lynx.
