A new regulation on invasive alien plants in Wallonie (Belgium)

From now on in Wallonie (Belgium), the provision, use or management of plant species or the transport of soil potentially contaminated by invasive alien plants should be in accordance with the ‘circular related to invasive alien plants’ approved on the 30th of May 2013.

Article 1 stipulates that planting invasive alien plants listed in Annex 1 is prohibited. These plants may only be planted in botanical gardens and arboreta if they are closely monitored and if measures are in place to prevent any spread of the species. Species listed in Annex 2 should not be planted within 50 metres of sites with a protection status according to the law on nature conservation or sites of high biological value. The introduction of species listed in Annex 2 is also prohibited within 50 metres of a watercourse.
Article 2 indicates that the movement of soil contaminated with seeds, rhizomes, tubers or any part of an invasive alien plant which could spread the species is prohibited. It is recommended to avoid the use and movement of soil from areas on which invasive alien plants listed in Annexes 1 and 2 are present, except if the soil is adequately treated. In particular, the presence of Fallopia spp. and Heracleum mantegazzianum (Apiaceae, EPPO List of Invasive Alien Plants) will be the object of specific measures.
Article 3 states that the management of the plants listed in Annexes 1 and 2 should follow good practices validated by the Public Service of Wallonie.
Article 4 indicates that waste from the management of invasive alien plants populations should be gathered and destroyed.
Article 5 deals specifically with Fallopia spp. and indicates that the cutting and removal of rhizomes of Fallopia spp. is prohibited as this practice may spread the plant.
