    The influence of selected environmental factors on shaping sandy beach habitats as a place for the growth of psammophilous and halophilous plants were the purpose of a research performed in the years 2013–2014 on Przytorska Sandbar (Natura 2000 area „Wolin and Uznam” PLH320019). The research was performed on a beach section, which was excluded from recreational use, and closely bordered with the external port basin of the Liquid Natural Gas terminal under construction, where also the abrasive influence of storm surges had been diminished. Research results indicated a dominant influence of aeolian sand material accumulation in shaping embryo dunes inhabited by pioneer species of psammophilous and halophilous plants - Elymus farctus subsp. boreoatlanticus and Honckenya peploides – species characteristic of the plant association of Honckenyo-Agropyretum juncei R.Tx. 1955, identifying the natural habitat of the initial stages of coastal white dunes (habitat code: 2110), the parts of which had been observed in the research area as a classically shaped form. The presence of Ammophila arenaria and Leymus arenarius creating initial forms of grassy vegetation association of Elymo-Ammophiletum indicated a proceeding stabilisation of embryo dunes – evolving into a foredune. A strong sea accumulation of sand material and simultaneous decrease of abrasive storm-tide influence enabled the development of an ecologically and geographically foreign species Salix daphnoides, diasporas of which were located in the area of lower beach.
