There are also rules that you need to adhere to when picking invasive plant species.

The remains must not be thrown away in nature or in compost.

Then there is a great risk that they will spread.

- For it to work, it is required that people come.

That's a bit of the thing with invasive species control.

At the same time, the authority is dependent on help in discovering where the invasive species are spreading.

The public is asked to report finds of plants or animals on the Species Portal.
