Abstract. The aim of the study is to analyze the taxonomical structure, origin and distribution of the anthropophytic element on the territory of Lozenska Mts. and to assess the degree of synanthropization of the flora. The study was carried out in the period 2016-2018. During the field studies the transect method was applied for collection and identification of the plant material. In view of possible comparisons and calculations of the synanthropic indice the surveyed area was divided into 4 sub-regions. On the territory of the Lozenska Mts. 274 species and 8 subspecies from 196 genera and 57 families were found. The anthropophytes are predominantly therophytes. In phytogeographical terms the character of the anthropophytic flora can be described as European-Asiatic with a strong boreal and less sub-mediterranean influence. Four species of nature conservation status were identified among the anthropophytes. The antropophytes of Lozenska Mts. are 33.3% of its vascular flora and almost twice of the same group of plants in the flora of Bulgaria (14,0%). The north-eastern part of the mountain is most affected by the synanthropic processes and less affected is the north-western part. For the period 1961-2018 the percentage of the anthropophytes in the surveyed area is increased by 7.2%, while the participation of the autochthonous species is decreased by 3.8%. The high values of calculated indices of synanthropization show the intensification of this process on the territory of the mountain.
Key words:  synanthropization, anthropophytes, autochthonous flora, ecological groups, Lozenska Mts.
