Withits strong clonal growth through suckers, this evergreen shrub outcompetes nativespecies and affects dune succession. To prevent further secondary spread andmitigate its impact, there was an urgent need for knowledge on the effectiveness ofcontrol measures, both at the level of individual plants as on habitat level. Here, wereport on two removal experiments. First, small Berberis clones were subjected to oneof four treatments (manual uprooting, foliar herbicide application, stem cutting followedby herbicide or salt application), with regrowth being monitored up to one year aftertreatment. Plants proved most susceptible to foliar herbicide application (5%glyphosate solution), resulting in 77% of the clones apparently killed. Second,mechanical removal using a heavy excavator was applied in a highly infested area(350 m², with nearly 100% Berberis cover) and accompanied by manual removal ofsmaller rhizome/stolon fragments.
