Brussels’ Green Spaces Unit is campaigning to eradicate invasive plants such as black cherry, Japanese knotweed and giant hogweed from the city.
The Brussels unit, which looks after the green areas and parks, intends to map the plants’ habitat in the city and then to destroy them. If plants are found on private property it is up to the owner to get rid of them.
The unit uses both prevention and population control and has drawn up a code of conduct in association with other bodies working in the same field.
In Belgium all invasive plants are registered with a database called Harmonia. At present there are about 60 plants on the list.
