Alpine and subalpine grasslands over carbonate bedrock in the Sharr Mountains (Kosovo)
摘要
Alpine and subalpine calcareous grasslands of the Balkans (class Elyno-Seslerietea) are floristically rich but remain insufficiently documented in parts of the Sharr Mountains. This study aimed to classify the (sub)alpine grasslands of Mt. Luboten (Kosovo) within the syntaxonomic framework of the central and southern Balkans, to clarify the status of previously reported communities and to describe newly recognised vegetation units.
MethodsDuring 2017–2019, 110 phytosociological relevés were recorded using the Braun–Blanquet approach, stored in TURBOVEG and analysed in JUICE. A regional dataset (274 relevés) combining new and literature data was classified by hierarchical clustering and evaluated with synoptic tables. Diagnostic taxa were identified using φ-fidelity with Fisher’s exact test (p < 0.05). Ordination (DCA) and unweighted mean Pignatti indicator values were used for ecological interpretation; life forms and chorotypes were summarised at the group level.
ResultsSix clusters represented the vegetation of Mt. Luboten. One association was confirmed and nomenclaturally corrected as Caricetum sempervirentis- kitaibelianae Rajevski
Mt. Luboten hosts distinct limestone grasslands dominated by Balkan and high-mountain elements, including several previously unrecognised syntaxa. These results refine the Balkan framework of Elyno-Seslerietea and support the high conservation value of alpine and subalpine calcareous grasslands in the study area.
