Riparian plant species
The riparian plant alert list consists of 3 species reported by Belgian ornamental plant catalogues and 1 additional species (i.e. Koenigia polystachya) not found in catalogues. Those species are poorly established within the LIFE RIPARIAS territory and known to be invasive in neighbouring areas. These species have an environmental risk score ranging from medium to very high, most often with a moderate confidence level (see the alert list report).
