Abstract. Sakhalin grass communities contain a wide variety of flora species and the formed cenoses. The aim of our work is to conduct an ecological and floristic classification of dune vegetation of Sakhalin Island and include the obtained results in large syntaxonomic generalizations of vegetation of Russia. Geobotanical studies were carried out in the summer of 2022 and 2023 on Sakhalin Island. Data processing was performed in Microsoft Excel 2013 and Ibis v.7. The syntaxonomic survey was carried out using the J. Braun-Blanquet’s approach; the names of the new syntaxa were given in accordance with the International Code of Phytosociological Nomenclature. The study of dune vegetation of Sakhalin and subsequent analysis allowed us to establish new locations of a previously known association Leymetum mollis Ohba, Miyawaki et Tx. 1973 and to distinguish a new association Ligusticum scoticae-Leymetum mollis ass. nov. with two new subordinate subassociations Ligusticum scoticae-Leymetum mollis typicum subass. nov. and Ligusticum scoticae-Leymetum mollis artemisietosum vulgaris subass. nov. The new syntaxa are included in the class Ammophiletea Br.-Bl. et Tx. ex Westhoff et al. 1946.
