Sažetak
St. Ilija Mountain (St. Elias, 961 m a.s.l.), the area included in this study, is located on the peninsula of Pelješac (355 km2) in south Croatia, eastern Adriatic coast. The peninsula is included in Croatian Important Plant Areas (IPAs). The study area stretches over a surface of ca. 1500 ha. Geologically, the ground mostly consists of highly permeable limestones, while dolomites account for the smaller portion of the rocks. This region has been strongly affected by past human activities since at least the Early Neolithic. Altogether, 182 phytosociological relevés were set to investigate the community diversity, vertical distribution of the vegetation and land use on the entire mountain range. The field surveys were done from 2011 to 2016. Altogether, 54 plant associations, excluding anthropogenic vegetation of the Papaveretea rhoeadis, Sisymbrietea and Chenopodietea were recorded. In general, three belts can be recognized: i) belt from the sea level to ca. 100 m, characterized by the Oleo- Ceratonion vegetation ; ii) 100 m to 300(-450) m, characterized by a vegetation of Quercetea ilicis (Mediterranean shrubs) ; iii) 300(-450) to 960 m sub-mountain belt with a Erico- Pinetea, Festuco- Brometea and Ononido- Rosmarinetea vegetation. The lowermost areas on the southwestern slope, which is influenced directly by the sea, are covered with communities of the rocky, and rare gravel and sandy coasts (Limonion anfracti-cancellati, Euphorbion peplidis and Ammophilion). The evergreen and semideciduous calciphilous holm oak woods are ascribable to Fraxino orni- Quercion ilicis. The vast majority of Pinus halepensis woods (mostly the Pistacio-Pinetum halepensis association) develope mainly in Oleo-Ceratonion, but they also appear in the Fraxino orni-Quercion ilicis. The dry grasslands of the Scorzoneretalia villosae developed on the steep rocky slopes and include many local stenoendemic or Illyrian – Adriatic endemic species. Endemic Pinus nigra ssp. dalmatica forests (the Erico manipuliflorae- Pinetum dalmaticae association) develops on dolomite mostly in the range 800 – 900 m a.s.l. Some abandoned agricultural areas are important orchid rich sites. In sum, the relatively high vegetation diversity may be explained by the relatively large surface area and the range of altitudes. Anyway, the management of the forests must attain the limitation of fires, grazing and uncontrolled recreation activities.
