Best management guide for invasive alien aquatic and riparian plant species
The EU LIFE funded project RIPARIAS has produced a best management guide for the control and eradication of invasive alien aquatic and riparian plant species. The guide details methods for the control of specific alien plant species and the methods presented have been shown to have an acceptable level of effectiveness at the local scale (Table 1). The management guide also includes case studies for some of the species where such management actions have taken place against specific species in Belgium. These case studies describe both success stories and failed management actions.
