CONTRIBUTIONS REGARDING THE STUDY OF THE RUMICION ALPINII RÜBEL 1933 ALLIANCE IN THE LOTRU MOUNTAINS PUBLISHED

Mariana Niculescu, Ilinca Imbrea, Alma Lioara Nicolin
The territory under research is located in the Lotru Mountains, part of the Meridional Carpathians. Lotru Mountains are dominated by the platform between Şteflesti Peak (2212m), and Cristeşti Peak (2233m). This platform spreads a branch to the south-western part, and is made up by Piatra Albă height (2179m) – Preajba - Tâmpa (1190m). The height descends to Lotrului Valley, and this is it when it curves to the east (Obârşia Lotrului). The biggest drainage tank of these mountains, with an important flow and energy is Lotrului tank. Its springs flow from Parângul Mare Mountains, from a glacial river. In the beginning, it flows from south to the north, and then suddenly turns to the right, in the pace called Obârşia Lotrului. In this paper, we present 3 plant associations, within  Rumicion alpinii Rubel 1933 alliance because the human impact in this type of habitat are very increased and their generally conservation value is important: Rumicetum alpini  Szaf., Kulcz. et Pawl. 1923, 1927, Rumici obtusifolii - Urticetum dioicae Kornaš 1968 (Syn. Urtica dioica - Rumex obtusifolius Anghel et al. 1965) and Veratretum albi  Puşc. et al.1956.
