PHANEROPHYTE IN THE FLORA OF BILEĆA (THE REPUBLIC OF SRPSKA, BOSNIA AND HERZEGOVINA)

Abstract

The paper presents the data of the research on dendroflora collected in the municipality of Bileća. The floristic study as conducted during the 2017 and 2018 vegetation seasons. The presence of 114 species and subspecies of plants was confirmed, grouped into 73 genera and 35 families. In terms of life forms, phanerophytes from the group of deciduous trees were dominant. Phytogeographical analysis showed that species are most often from Sub-Mediterranean, Eurasian and Sub-Atlantic areal groups. The analysis of ecological indices for basic ecological factors determined the dominance of submezophytes. Most species prefer neutrophilic and basophilic soil reactions. In relation to light, the most numerous species are semi-sciophyte, half-shaded plants; in relation to temperature, the prevalent group is located at the transition between mesothermal and thermophilic plant species.
