This is an interesting question, the one exotic is not the other.Species like the Japanese knotweed or the American birdwatchers are notorious for the damage they inflict, and if they are in your garden it can even bring down the value of your home.
Yet these two are not on the European black List of flora and Fauna[1 which was introduced in 2016.There are three kinds of bears claw, including the vitriolic giant Bearclaw, and four types of squirrels. There are also a lot of former garden and aquarium plants, such as the summer Aster and the giant Springbalsemien. [2 This list consists of species that cause so much ecological and monetary damage that there is a ban on its import.It is also known as a list of deaths, because local policy often fights them in this way.
Exots are species that have landed in the Netherlands after 1500.This line is drawn because we see many species coming in from the Americas, the Colombian exchange. That means that the rabbits and the seven leaves, both with intent here brought by the Romans, do not belong to the exots. Yet they bring much damage to nature. Also, according to this arbitrary line, man is not an exoot, although I absolutely agree with the other answer that they have made the most damage.
The kind I first thought of was the Muskusrat, actually a small beaver species.Of these, 1905 5 copies came from Alaska. In the meantime, around 100,000 are killed annually, and the Empire has to fund millions of damage to dikes. [3 Three of my uncles were muskusrattenbestreiders for the empire.But of this man has more damage than nature.
Of the escaped aquariumgoers (well, most were simply expelled after they became too big) are mainly the American Howler frog, the sunfish, the snapping turtle[4and the goldfish notoriously.The first two are fought with policy, you hardly hear anything from it, but they have suffered a lot of damage. The goldfish is still the most harmful, not only are the omnivores who eat the young Grut of many other species, they also rooting in the soil so that many aquatic plants can no longer grow there.
Some species are especially destructive to their native counterpart, for example the American squirrels for the red squirrel, the Japanese oyster for the Dutch oyster.The latter has drifted away from the ordinary oyster, but has a much more whimsical shell than the Dutch, which makes Japanese oyster banks a good hiding place for smaller molluscs such as mussels. So they also have an advantage.
If you think now, what are there many copies from Japan and America, that’s just code for 芒 鈧?虄somewhere out of those contreien, we don’t know it as well, but this sounds the most far away/threatening. 芒 鈧劉 Tis a bit of xenophobia which sneaks into the popularly.
Incidentally, we in the Netherlands are much less affected by exots than in island nations like the UK and Australia, or in the Americas.This is because we have always been in contact with Africa and Asia in Europe, and so there is a huge area of exchange. This means that only the most competitive species managed to maintain themselves.
This was also the reason why the first Europeans in the Americas hastily rowed the indigenous people with diseases, while in turn they only got syphilis.Although we suffer from 芒 鈧?虄americaanse芒 鈧劉 and 芒 鈧?虄japanse芒 鈧劉 exotics, there are many more exotics from Eurasia that make hostility in the rest of the world than reversed. For example, worldwide, I think that European honeybees and bumblebees inflict enormous damage on local pollinators.
This whole story and yet no real answer.I am guessing that the most damaging exotic for our nature is a goldfish, or an invasive water plant like the water plague, because they also stifte a large part of the waterways.
Apart from man do you mean?
Tricky question.Collar Parakeets compete our songbirds away
Nile Goose oppressing geese.
American lobsters have committed an attack on our aquatic life.
None of these species, however, have caused the damage that man has done and since it comes from Africa I consider it an invasive exotic
