ALLUVIAL AND LOWLAND HAY MEADOWS IN THE MEDIAN BASIN OF THE RIVER TIMI? (SOUTH-WESTERN ROMANIA)

In this paper we present some aspects concerning the chorology, floristic composition, syn-ecology, and dynamics of the alluvial and lowland hay meadows in the River Timi? basin. Agrostis stolonifera dominates depression areas with high moisture for the entire year, while meadows of Alopecurus pratensis can be found on plane lands that are moist in spring and drier in summer. Lowland hay meadows with Arrhenatherum elatius are fragmentary and are met on the flooding plain terraces and on slightly sloppy lands. On moister lands, not cultivated recently, around the villages, there are frequent coenoses edified by Elymus repens, together with Agrostis stolonifera and numerous species considered weeds.
