Lilac, scilla, daffodil flower and genuine honeysuckle – värstingar in nature when it comes to dissemination and mainstreaming, according to a new list from the Swedish Species information centre. They multiply with lightning speed and threaten to take over another växlighet. In the future, the sale can be stopped.

the Lilacs have begun to fröså in california, and scillor and other bulbous plants verging on taking over the seriousness of Öland and Gotland meadows. Good or bad? No one can say for sure, but something has happened with the vegetation, says Mora Aronsson, botanist at the knowledge centre Swedish Species information centre.

The warmer climate means that more plants will begin to behave in a new way. Most of the garden plants were brought into the country in the 1800s, ” says Aronsson. It was then the common people got the opportunity to cultivate their gardens, and beautiful rarities on the basis of standing high in the course. But now when the climate has become warmer, they have become a problem.

– Sure, you might think that it is beautiful with forests full of daffodils and meadows, the blue of the scilla, but we are not taken into account. We have made the list according to the strict scientific conditions.

Climate impact

– We have looked at how they spread, and what impact they have on nature. We have also had a climate change scenario for 50 years, but it is very difficult to predict how it will be, ” he says.

Work has resulted in a new, hot list of around 600 alien species in Sweden, of which 100 are invasive. That is, plants that spread quickly and threaten to displace other vegetation.

the Worst is the problems in the south of Sweden. There is noticeable climate change quickly, and new species will begin to rapidly displace the native.

– We have seen a pine forest in Åhus, which is completely impermeable by a 70 feral buskarter. Where is spirea and wild berries so it is not possible to get through.

Lilacs on värstingslistan

A hundred of the plants on the list are particularly aggressive – sweet trädgårdsälsklingar as lilac, vårstjärnor, lammöron, praktlysing and smelling real honeysuckle is a värstingar.

– the Spread also depends on how many places the plants may be spread from. For example, lammöron are in every torpträdgård, and jättedaggkåpa was the year perennial a few years ago. Now you can see it in the roadsides everywhere, ” says Mora Aronsson.

Swedish Species information centre has not proposed any measures, but it may come in the future. Artdatabankens list is still preliminary, and are undergoing a scientific examination. At the end of the year it will be handed over to the environmental protection agency and the Marine and water authority, which will send around to the various bodies consulted. Then, the government has to decide on the list, and then also the sale of some plants be stopped or limited. Fixed to its delay it two years.

Restrictions can come

– My reconnaissance is that there will be restrictions on certain. You will probably start in the end to take the most expensive first, which vresros, black cherry and lupines.

this is The first time such work is done in Sweden, ” says Mora Aronsson.

– Then in 2015 there has been an EU-list of the 59 species, seven of them are plants that are found in Sweden. But this is a systematic review of the plants and animals in Sweden, similar to the work carried out in Norway.

the Question is what the gardeners are going to do as has, for example, lilac, snowberry, or praktlysing in the clog.

– You should make sure that they do not spread, but remain where they should be. If they do not, you should probably remove them, ” says Mora Aronsson.
