The purpose of this work is to present a synthesis of the researches realised on 28 grasslands from Banat during 2003-2005 concerning the impact of some species on grassland and the determination of their invasive character. Most of the studied species have acted as invasive, this fact being manifested through the increase of the coverage index of the surface from a year to another. Even this study is realised at local scale, the results, respectively the study method can be applied at a regional scale too. Also, in this way can be characterised other species that are suspected from the invasivity point of view to be noxious.
