APPROACHES ON FLORISTIC COMPOSITION AND PASTORAL VALUE OF SOME PERMANENT PASTURES IN HĂUZEŞTI AREA ( WESTERN ROMANIA) PUBLISHEDCarmen Durău, Alexandru Moisuc, Veronica Sărăţeanu
Because of the expansion of agricultural crops that cover mainly fertile land areas, pastures were constraint to draw back on less fertile lands. Man’s intervention in the structure of pasture ecosystems consists in the way he harvests biomass and in the land maintenance works. Man’s impact on the biocoenoses changes their composition and structure. The reason that land surfaces are improperly managed is due to the fact that the land has become private property and the new owners aren’t concerned about the applying of any management. All these aspects correlated with the decrease of the number of cattle resulting in a lower grazing pressure have influenced the dynamics vegetation and pastoral value. In this paper we make appreciations on the floristic composition and on the pastoral value of some permanent pastures around the Hăuzeşti area, trying to identify measures to improve. The study took place in Western Romania in the hills of Surduc which are situated at the bottom of the Poiana Rusca Mountains, east from the Bega – Luncani River and north from the terraces of the Bega River. The study was carried out on two permanent pastures, assessment of the vegetal cover was done through the double meter method and the results were processed on the ground of the botanical sampling, this method helping to the calculation of some indexes of the vegetation. The statistical method used was the analysis of the correlations. Following the study, we drew the conclusion that irrational exploitation of these ecosystems resulted in the simplification of the floristic composition and in the decrease the pastoral value, which asks for new measures to be adopted in their management. Therefore our intention to continue this study is to notify the specialists regarding the implementation of rehabilitation measurements needed for the improvement of the quality and quantity of forage produced on these surfaces.
