SCI “ZAPADNA STARA PLANINA AND PREDBALKAN” – FLORISTIC STUDIES ON XEROTHERMIC OAK FORESTS
Keywords:
xerothermic oak forests, flora, SCIAbstract
The main aim in the present study is to identify the floristic diversity of xerothermic oak forests with predomination of
Quercus cerris L. and Quercus frainetto Ten. in SCI “Zapadna Stara planina i Predbalkan”. The inventory of the floristic
complex resulted in more than 100 species of higher plants that belong to almost 80 genera and 40 families represented in the
Bulgarian vascular flora. The biological spectrum made based on Raunkiaer’s life forms shows the predominance of hemicryptophytes
and takes an intermediate position between the spectrums of the forests in the temperately warm and temperately cold
zone. The phytogeographical spectrum shows the predominance of European-Asian and subMediterranean fl oral elements
which are represented equally (about 20% each). They are followed be the European, European-Mediterranean and sub-Boreal
fl oral elements (about 11% each). The anthropophytes are also discussed. The results of the present study will be a fundament
of a further complex investigations of the xerothermic oak forests in the protected site and will be useful for the defining of
succession processes in the discussed forests.
