Vegetation relating to the alliance Arrhenatherion elatioris has been studied in the central part of West Bulgaria. Classification and ordination of vegetation were performed. As a result of the analyses, four associations have been identified: Ranunculo repentis-Alopecuretum pratensis, Tanaceto vulgaris-Arrhenatheretum elatioris, Pastinaco sativae-Arrhenatheretum elatioris and Ranunculo bulbosi-Arrhenatheretum elatioris. In ass. Ranunculo repentis-Alopecuretum pratensis, two distinctive subgroups have been observed, differing in humidity of their substrate. The more humid one is the typical variation of the association, while the drier one is described as var. Eryngium campestre. The mode of vegetation use within the framework of the four associations is commented on.
