APPROACHES ON THE DYNAMICS OF THE FLORISTIC COMPOSITION OF A BANAT HILL GRASSLAND (WESTERN ROMANIA)
AbstractIn Romania, most hill grasslands are improperly managed, being either occasionally grazed or abandoned. From this perspective, the goal of the present paper was to monitor the dynamics of the floristic composition, of the pastoral value and of biodiversity under different management conditions. The permanent grassland we analysed is one in which dominant species have been Agrostiscapillaris L. and Anthoxantumodoratum L. Observations were carried out for five years (2008-2012) on five permanent plots mowed twice a year in 2008 and 2009, and mowed once and occasionally grazed by sheep in 2010, 2011 and 2012. Sampling was done with the linear method which allowed the calculus of some parameters such as specific contribution (SC%), pastoral value (PV) and Shannon-Weaver diversity index. The statistic method used was correlation analysis. Results show that occasional grazing by sheep in the last three years had a significant impact on the analysed parameters.
