VEGETATION ASPECTS OF SOME HABITATS WITH VIPERA URSINII FROM S R TURILE LEVEE (DANUBE DELTA)

This study aims to present and analyse, from phytosociologic perspective, the phytocoenoses preferred by Vipera ursinii individuals, of the S r turile levee (Danube Delta). Our field investigations showed that most of vipers have been observed in the plant communities with relatively tall grasses and high cover and in the ecotonal areas that are appropriate for thermoregulation. The analysis of the relevés allowed the identification of three phytosociological associations: Juncetum maritimi (Rübel 1930) Pignatti 1953, Juncetum littoralis Popescu et Sanda 1976 (Cl. Juncetea maritimi Br.-Bl. 1931) and Agropyretum elongati I. erb nescu 1965 (Cl. Festuco-Puccinelietea Soó 1968).
