نبذة مختصرة : International audience ; The development of aquatic plant beds can obstruct boat traffic, hinder the practice water activities, and impact functioning freshwaters. In order to mitigate their effects, mechanical removal is often preferred management solution. objective this study was test, in mesocosms, effect frequency (none, one, two cuts) cutting dates (May and/or July) on regeneration colonization capabilities Egeria densa, an invasive alien species France. date had no E. but cuts significantly reduced plant’s biomass. Removal produced numerous fragments, which exhibited very high survival anchoring rates. However, summer fragments with lower abilities compared from spring cutting. Mechanical only temporarily biomass could promote formation new generated by dispersed flow.
