摘要

Wishing to meet present economic demands in a continually better way and also to develop a database for better guidance in the valorisation of the vegetal potential of a certain area or of a certain vegetal group, more and more phytocenologists and agriculturists are carrying out analyses of the different categories of plant communities. On the basis of such important factors as the share of these categories in the particular features of the species important for the different sectors of social and economic activity, on the plant organs or parts harvested for practical purposes, as well as on the evolutionary stage of the plant communities studied, specialists are increasingly capable of defining the intensity of their valorisation. In this paper, we present an assessment of the dynamics of the vegetation of grassland that was initially a Poa pratensis L. one, emphasising the effect of under-exploitation on the fioristic composition. The inventory of the vegetal cover was made with the help of thedouble-meter method, while observations consisted of the analysis of 25 botanical samples over 5 years (2003-2007). Restricting occasional grazing and diminishing the number of cuttings over the 5 years mentioned above resulted in the grassland being redirected in a particular direction, in which such species as those belonging to the Astereaceae family are favoured (i.e. they develop extensively), while species belonging to the Poacea and Fabaceae families cover fewer and fewer areas and rank, therefore, among disadvantaged grasslands.
