Bremen tells the invasive needle herb: take measures!

In the idyllic waters of the park on the left of the Weser, something happens - and that has it all. The invasive conifer spreads undisturbed there. This herbal evil presents itself in the form of "thick mats or upholstery", which literally suffocate the water and gradually displace the domestic flora and fauna. There is clear, there is something and those responsible have reacted. Weser Report reports that the needlewort is on the action list, which underlines the need for action.

From July 7th, the large project will therefore start combating, which is expected to take ten weeks. An application for control measures has been approved and one million euros are available for this. The federal government pay 90 percent of the costs, while Bremen bears the remaining 10 percent. The Hanseatic natural development (Haneg) was entrusted with the project control and implementation and has the necessary "hand" to thoroughly discrassed the waters.

planned measures

Complete elimination of the needle herb is assessed as unrealistic. Nevertheless, foothills and roots should be removed thoroughly. It is planned to put the plants into a depot and cover them with half a meter of sand. In order to ensure the quality of the water, it has to pump and filter a few days before it is led to Huchtinger Fleet.

The residents on the Hohenhorster Weg can also count on information letters in which they are informed about the necessary construction site access and the associated restrictions when parking. After all, everyone wants to keep an overview when it comes to the important measures.

warnings of the federal government

But not only in Bremen there are concerns about the needle herb. The BUND appeals to the pond and aquarium owner, not to buy or to expose itself to the field, because it can be rapidly corrected via small stemsticks. When it comes to graying of garden ponds, care should also be taken to ensure that it does not get into nature. Here it is important to dispose of the plants in the garbage to prevent further spread. A trade ban for needle herb would be desirable, but has not yet been enforced.

In Germany, around 900 neobiota species are established, as the Federal Office for Nature Conservation . Plants make up the lion's share of this. The growing number of invasive species is directly related to global trade and traffic - and this suggests future challenges. Climate change could further make the spread of these species easier due to milder winter.

to the local population and conservationist, only hope that the fighting forces in Bremen do justice to their goal. Because one thing is certain: the domestic waters urgently need help to maintain the endangered habitat for many plants and animals.
