We should not just introduce exots.
Plants, shrubs and trees often have a very complex ecology.Certain birds, insects, etc. live on and with those plants.
If you enter a plant, that community is lacking (luckily, you would think almost, because those animals and creatures would not do much damage in the new environment?)
On the other hand, wiping seems to be almost impossible, especially because you have to do it very well organized.A root can sometimes grow again after a few years.
Rabbits, tulips and daffodils are the most famous exots.By adjusting the definition, they become indigenous. ‘ Plants that were not in the Netherlands for the last hundred Years ‘, for example. There are all sorts of stories about some plants, but are they true? The Japanese knot on the other side of the ditch, is mown once every year by berm management and expands very slowly.
The best thing is to leave things on their course.If you really suffer from the plants, then those large plants are easy to remove. Always cut off the aboveground section or pick away. If you hold this for a few weeks, the root is released and it will come loose.
The most difficult garden plant I find burr.Ecologically very valuable and truly indigenous, and even delicious with the blackberries, but he is difficult to curb. Good gloves.
The policy (at least in Belgium) is already to avoid exots.One conducts research into the conscious exoot, estimates the danger for the own fauna and flora and if necessary, the goal is to set the entire outcrop.
In most cases, exotes are mainly a danger to plants and therefore also to agriculture.However, there may also be dangers to indigenous indigenous, (fragile) species. They risceren to disappear by doing the new kind. In Belgium There is currently a danger for OA. Some pigeon species: An alien bird makes them as good as impossible to breed yet by taking all their breeding holes.
The fear is mainly because the ecological file of a region is the result of thousands of years of evolution.”Even a minute could have a big impact,” is the premise of the government.
Yet it is still possible to buy, for example, those alien, cute (but not so sweet) water turtles.Two years later they are no longer adorable because of too big and they have to go away. In Flanders This was very easy until a few years ago: The animals were dumped at organisations such as the Nature Aid Centre. That discharge was also free. When the increase in water turtles increased so explosively, the Nature Aid Centre decided to charge five euros per turtle. Only five euros. This was apparently priceless, because since then they have been massively deported to ponds and the like in nature.
What is going to be the consequences of this is not yet clear.It is well established that it is very strong animals that are easily adjusted. Our climate is too cold for them, but they are strong enough to survive the winters here.
Nowadays you can find water turtles on almost every pond in Flanders.Add to that it’s strong and aggressive creatures that are just about everything.
There should be a better and more consistent prevention policy, but global warming, international trade and human action will make it impossible to avoid seeing more and more alien fauna and flora.
