<p>In this study I investigate the sensitiveness of Bishop's goutweed (Aegopodium podagraria L.)to mechanical damages in an experiment with artificial clipping. Based on personalobservations of A. podagraria during several years I hypothesise that i) A. podagraria indifference with other species, for example different species of grass have difficult to recoverfrom mechanical damages ii) in a site with several other species present A. podagraria willhave harder to recover from mechanical damages than in a pure stand iii) as purer a stand withA. podagraria is, the harder other species will have to establish after the removal of aboveground parts of A. podagraria. The main conclusion of this work is that mechanical damagehas a significant effect on the vegetation cover of A. podagraria. The experiment also provethat a high grade of monoculture favours the ability of A. podagraria to recover frommechanical damage. It could however not be proven that high grade of monoculture of A.podagraria puts constraints on the ability of other species to establish on plots where A.podagraria is removed.</p>
