Comparation of floristic composition of Black pine - cinquefoil (Potentillo heptaphyllae-Pinetum gocensis B. Jovanović 1959) and Black pine - winter heath forest (Erico-Pinetum gocensis Krause 1957) on Crni Vrh Mt. near Priboj, Serbia

Crni vrh near Priboj is a part of serpentine-peridotite massif of Balkan peninsula, which is located on the border between Ilirian and Moesian floristic provinces and it possesses high vegetation diversity. Black pine forests are the most widespread vegetation segment of this area. The comparation of floristic composition of black pine plant communities Potentillo heptaphyllae-Pinetum gocensis B. Jovanović 1959 and Erico-Pinetum gocensis Krause 1957 is presented in this paper with the aim to ascertain what is the difference in the floristic composition between these two communities, considering they are located in immediate vicinity of each other. Testing with t-test showed there are no significant differences between researched communities considering canopy and elevation. There are significant differences in the coverage of herbacious layer and aspects in which these communities grow. Total number of recorded plant species in communities is 97, of which 39 occur in both communities. Jaccard similarity index is 0.39. Community Potentillo heptaphyllae-Pinetum gocensis B. Jovanović 1959 is more xerophilous and intolerant than community Erico-Pinetum gocensis Krause 1957, and contains more xerophilous elements in the spectrum of distribution types also. Apart from similarities, which are the consequence of the same geologic bedrock, these two communities show also significant dissimilarities which differ them clearly
