CONTRIBUTIONS TO THE KNOWLEDGE OF THE HIERACIO ROTUNDATI-FAGETUM ASSOCIATION (VIDA 1963) TÄUBER 1987 FROM THE NORTHERN PART OF THE SEMENIC MOUNTAINS

Abstract

In the current work, we present a phytocenological study of the phytocoenoses of the association Hieracio rotundati-Fagetum (Vida 1963) Täuber 1987 (Synonyms: Hieracio transsilvanico – Luzulo - Fagetum Vida 1963), identified in the acidophilic beech forests in the northern part of the Semenic Mountains, located in the southwestern part of Romania. The characterization of the analyzed association, as well as the presentation of the synthetic table, were carried out by selecting the most representative releves conducted in the Luzulo-Fagetum type beech forests belonging to the Semenic Mountains. The biodiversity study of this phytocoenosis was analyzed in terms of physiognomy, floristic composition, spectrum of life forms, floristic elements, the influence of ecological indices, soil moisture, temperature, soil chemical reaction, and karyological spectrum.
