A recently completed project on the Natura 2000 sites of Prespa National Park revealed that the area hosts 49 habitat types according to the EU classification, of which eight have a narrowly restricted distribution in Greece. The priority habitat type “*6260 Pannonic sand steppes” is reported here for the first time for Greece. The new locality represents its southernmost occurrence on the Balkan Peninsula. The aim of this paper therefore is to describe the Greek stands of this habitat type, investigate the factors affecting its occurrence and discuss the associated conservation issues. This is based on a total of 87 releves sampled for this study and 8 additional releves from the literature. The releves were classified by applying TWINSPAN and ordinated using Detrended Correspondence Analysis (DCA). Six vegetation units could be distinguished. One of these corresponds to the habitat type *6260 and was found exclusively on inland sand dunes. Syntaxonomically, we assigned this unit to the alliance Sileno conicae-Cerastion semidecandri s.l. of the class Koelerio-Corynephoretea. Its occurrence in the study area seems to be determined by climatic factors, as well as by the sandy substrate, while anthropogenic disturbances such as grazing also appear to be beneficial to some degree. Apart from the Koelerio-Corynephoretea, another five grassland classes were distinguished in the national park, namely the Thero-Brachypodietea, Stellarietea mediae, Festuco-Brometea, Daphno-Festucetea and Juncetea trifidi. Nedavno končani projekt o območjih Natura 2000 v Narodnem parku Prespa je pokazal, da je na območju po EU klasifikaciji 49 habitatnih tipov, od katerih jih je osem z ozko razširjenostjo v Grčiji. Pojavljanje prednostnega habitata “*6260 Panonske stepe na peščenih tleh” v Grčiji objavljamo prvič. Nova lokacija predstavlja najjužnejše pojavljanje na Balkanskem polotoku. Namen članka je opisati sestoje tega habitatnega tipa v Grčiji, preučiti dejavnike, ki vplivajo na njegovo pojavljanje in razpravljati o vprašanjih, povezanih z njegovim ohranjanjem. Raziskava temelji na 87 vegetacijskih popisih in 8 dodatnih popisih iz literature. Popise smo numerično obdelali s pomočjo TWINSPAN klasifikacije in z uporabo korespondenčne analize z odstranjenim trendom (DCA). Ločili smo šest vegetacijskih enot. Ena ustreza habitatnemu tipu in smo jo našli le na celinskih peščenih sipinah. Sintaksonomsko smo jo uvrstili v zvezo Sileno conicae-Cerastion semidecandri s.l. in razred Koelerio-Corynephoretea. Njeno pojavljanje v preučevanem območju je pogojeno s klimatskimi dejavniki in peščeno podlago, antropogene motnje, kot na primer paša, pa do neke mere nanjo vplivajo pozitivno. Poleg travišč razreda Koelerio-Corynephoretea smo v parku našli še pet travišč iz razredov Thero-Brachypodietea, Stellarietea mediae, Festuco-Brometea, Daphno-Festucetea in Juncetea trifidi.
