THE COROLOGY, ECOLOGY AND PHYTOSOCIOLOGY OF THE EUONYMO-SAMBUCETUM NIGRAE MOOR 1967 PLANT COMMUNITY IN THE SUBCARPATHIAN AREA OF OLTENIA, ROMANIA

Abstract

According to the phyto-sociological research carried out between 2007-2018, in the Subcarpathian area of Oltenia, there were identified one important plant community - Euonymo-Sambucetum nigrae Moor 1967. This plant community was not cited until now Oltenia. Since Romania has been mentioned only in Transylvania, by  A. Szabó from Sărățel-Chiraleș-Lechința. For the study of the vegetation in the this area, we have used the methods of phyto-sociologic research characteristic to the Central European phyto-sociologic School, which were based on the principles and methods elaborated by J. Braun-Blanquet (1926). In the phytocoenotic composition of this plant community, beside the dominant species Euonymus europaeus and Sambucus nigra, there are also: Ligustrum vulgare, Rosa canina, Clematis vitalba, Hedera helix, Poa nemoralis. The phytocoenosis have a small number of species, and the species with the highest abundance-dominance (AD) is Sambucus nigra. Euonymus europaeus missing from many phytocenosis. This plant community have been analyzed and characterized from the chorological, ecological, phytosociological point of views. They were also examined according to their floristic composition and physiognomy, syndynamics and economics
