PSAMMOPHILOUS PLANT ASSOCIATIONS FROM THE COASTAL AREA OF THE BLACK SEABETWEEN PERIBOINA AND PERITEAŞCA (DANUBE DELTA BIOSPHERE RESERVE)

Abstract

The coastal area between Periboina and Periteaşca channel is a narrow littoral belt which separates the Black Sea and the Razelm-Sinoe lagoon complex.On the sandy belt, less tall sand dunes(1-2 m) occur, bordered to the west by puddles and swamps more or less salted. There are four psammophilous plant communities on the embryonic sand dunes of the littoral belt and on the low surfaces of the dunes, in the frame of the habitats 2110 and 1210: Elymetum gigantei and Secali sylvestris-Brometum tectorum, respectively Cakilo euxinae-Salsoletum ruthenicae and Lactuco tataricae-Glaucietum flavae. A detailed description of these plant communities, inclusively of a new subassociation (Elymetum gigantei Morariu 1957 subass. crambetosum maritimae subass. nova) have been made in the paper. Information regarding the rare species from the psammophilous plant communities, conservation status of the habitats, anthropogenic pressures, risk factors as well as evolution tendencies of the dune habitats will be alsogiven in the paper.
