Several viewers throughout the country have testified about careless handling of park slides on municipal work. Excavation of fiber, water and wastewater or new and redevelopment has led to explosive spread of one of the world's most aggressive plants.

- It absolutely can be. It is one of the most common ways to spread park slides. To excavate land from one place and move it to another, says Lena Jakobsson of Gothenburg Municipality.

Very much built - large spread

Gothenburg is currently being built in many places in the city. This increases the risk of the plant spreading even more during the expansive period. Gothenburg Municipality today has no guarantees that this will not happen.

- Parkslide is disseminated in connection with construction work and we cannot guarantee that it will not, says Lena Jakobsson.

Today, park slide does not appear on either the EU or Sweden's national list of species that must be exterminated. This also means that the municipalities have no obligation to do anything about the distribution.

No demands

- There are no requirements on us but only recommendations, says Lena Jakobsson.

Do you think there should be requirements?

- It would have made it easier if there had been greater clarity, says Lena Jakobsson.

The municipality of Gothenburg is working on mapping the stocks that exist today. The ambition in the future is that this information will then go out to those who manage soil and plants in the municipality in the future.

- We hope that we will be done with that work for the 2020 season, says Lena Jakobsson.
