Popis: Paper description: Despite the high importance and conservation status of inland sand dune habitats, there is lack of information about classification and diversity of sand vegetation in Serbia. This research provides a detailed classification of vegetation dominated by drought-tolerant perennial grasses such as Festuca vaginata, on the basis of literature data and new releve material. Detailed classification of the alliance Festucion vaginatae only partly confirms the previous classication system. Two associations of perennial tussock grasslands on the sands are present in Serbia. These associations are divided into groups that mostly correspond to traditional subassociations. Abstract: Sand dunes are one of the critically endangered habitats in Europe. This vegetation type is under a strong anthropogenic influence. Its natural value is very high since many plant species with a narrow distribution are found there. The classification of Serbian sand-dune vegetation and the status of the described associations has not been validated by numerical analyses. This research presents an evaluation of sand-dune vegetation in Serbia on the basis of literature data, as well as new releves. Psammophytic vegetation in Serbia was classified into two alliances, annual and ruderal Bassio laniflorae-Bromion tectori and perennial Festucion vaginate . The aim of this research was the classification of the alliance Festucion vaginatae, perennial, drought-tolerant, tussock-forming vegetation on sand. As proposed by OptimClass, Jaccard distance and flexible beta data (β=-0.25) were used for the classification. Classification results were confirmed by detrended correspondence analysis (DCA) ordination. The result of the classification established that only two associations, Alysso gmelini-Festucetum vaginatae and Festucetum vaginatae , are present in Serbia. These associations are divided into groups that mostly correspond to traditional subassociations. https://doi.org/10.2298/ABS190717047C Received: July 17, 2019; Revised: August 3, 2019; Accepted: August 9, 2019; Published online: August 27, 2019 How to cite this article: Cuk M, Ilic M, Igic R, Sikuljak T, Vukov D, Carni A.
