Plant communities are thus expected to react differently to contrasted silvicultural systems. We compared plant species composition between stands submitted to a traditional management since many centuries . coppice-with-standards treatment stands intensively but infrequently disturbed and stands recently converted into a selective cutting system stands moderately but frequently disturbed over uniform edaphic and topographic conditions. We found significant differences in species composition between both systems. Despite a strong shift in species composition among different stages of the coppice cycle coppice-with-standards stands supported the highest number of true forest species. Selectively-cut stands were more homogeneous and characterized by ruderal generalist species. These fast changes in vegetation composition were related to differences in a group of factors
