Recognition and management guides (in French) for invasive alien plants in Belgium have been published by the Liege University and Gembloux AgroBio Tech.
The recognition guide provides elements for the identification of the following terrestrial and aquatic invasive alien plants: Aster spp. (Asteraceae), Azolla filiculoides (Salviniaceae), Crassula helmsii (Crassulaceae, EPPO A2 List), Egeria densa (Hydrocharitaceae, EPPO List of IAP), Elodea canadensis (Hydrocharitaceae), Elodea nuttalli (Hydrocharitaceae, EPPO List of IAP), Fallopia japonica, Fallopia sachalinensis, F. x bohemica (Polygonaceae, EPPO List of IAP), Heracleum mantegazzianum (Apiaceae, EPPO List of IAP), Hydrocotyle ranunculoides (Apiaceae, EPPO A2 List), Impatiens glandulifera (Balsaminaceae, EPPO List of IAP) and I. parviflora (Balsaminaceae), Lagarosiphon major (Hydrocharitaceae, EPPO List of IAP), Lemna minuta and L. turionifera (Araceae), Lysichiton americanus (Araceae, EPPO List of IAP), Ludwigia grandiflora and L.;peploides (Onagraceae, EPPO A2 List), Myriophyllum aquaticum (Haloragaceae, EPPO List of IAP), Persicaria wallichii (Polygonaceae), Solidago spp. (Asteraceae), Spiraea alba, S. douglasii and S.;x billardii (Rosaceae).

Guidance on the management of invasive alien plants is also provided in a series of documents. One guide deals with the mechanical and chemical control of Heracleum mantegazzianum, Impatiens glandulifera and Fallopia spp. along water courses. Prevention, eradication and containment recommendations are provided in another guide for Crassula helmsii, Hydrocotyle ranunculoides, Ludwigia spp. and Myriophyllum aquaticum. Summary management spreadsheets are also available for Acer rufinerve (Sapindaceae), Cotoneaster horizontalis (Rosaceae), Heracleum mantegazzianum, Impatiens glandulifera, Fallopia spp., and Spirae spp.
