Vegetation aspects of the Herghelia Village Hills

The spectrum of phytogeographical elements (Fig. 3) evidences the predominance of Eurasian species, on the background of which European, Euro-Siberian elements have interfered in various phyto-historical stages. Due to historical conditions in the postglacial period, the presence of a significant group of Mediterranean species is found.

In the karyological spectrum (Fig. 4), diploid species are dominant, followed by polyploid species. Part of the species are diplo-polyploid, and for a proportion of 1.80%, no karyological information was available. The great number of diploid species demonstrates the old age of this flora, which ensures a favorable genetic potential for the future phyto-evolution. Polyploids have a much higher capacity for phytocoenological competition.
