In Western Romanian Carpathians most of the permanent grasslands are comprised in High Nature Value areas, they being used in extensive manner. The main constraints reflected on the grasslands from the analysed area are represented by depopulation and decrease of the number of grazing animals. One of the main consequences of the decrease of the anthropic pressure on the vegetation sward is the increase of the incidence of the invasive native and non-native plants species. In some situations they are producing great changes in the vegetation sward by replacing the native species, and implicitly creating problems in the maintenance and balance of the original vegetation. Meanwhile they can alter the habitat features, change the succession trend, diminish the economic value of the affected surface and increase the costs necessary for the ecological restoration. The aim of this work is to realize an overview on the situation of the native and non-native invasive species present in different grassland vegetation types related with the several features of the vegetation grassland, respectively biodiversity, floristic composition and pastoral value. There were correlated vegetation features with the contribution of three non-native invasive species (Sarothamnus scoparius, Conyza canadensis and Juncus tenuis) and one native invasive species (Pteridium aquilinum). The study was developed on four grassland plots (Soceni, Lupac 1, Lupac 2 and Cuptoare) from Cara?-Severin County. Such studies are useful for the diagnosis of the vegetation conservation state, helps the farmers, administrators, and authorities in the setting of the proper management actions.
