HUMAN INDUCED ALTERATIONS IN PLANT BIODIVERSITY OF SĂRĂTURILE STRAND PLAIN - DELTA DUNĂRII.

On Sărăturile strand plain the natural flora is almost entirely consisted of herbaceous species, the environmental conditions preventing the appearance and natural evolution of trees. The diversity of flora was modified because of the establishment of a tree plantation with alien plant species in order to fix the mobile sand dunes and to improve the environmental conditions in Sf. Gheorghe town. Some of the species became invasive plant species, Hippophae rhamnoides colonizing the sand dunes outside the planted perimeter but contributing the fixation and stabilization of shore sand dunes.
