Abstract

The article is devoted to the study of the historical, systematic and dendrofloristic analysis of a state of the dendrology park «Druzhba» as an object of preservation and enrichment of biological diversity. The results of the inventory of park plantations 30 years after the creation were considered according to the literary sources and service materials of Uman Forestry Enterprise. 223 species and forms were found on the territory of the dendrological park belonging to 92 genuses, 37 families and 2 classes. Among the forms of life deciduous trees and shrubs (93.7 %) are dominated representatives of the section of Carnivorous (Magnoliophyta), and gymnosperms (Gymnospermae) are represented only by 14 plant species (6.3%), belonging to 2 families and 6 genus of the total number of species and forms. The analysis of the life forms showed that trees amount 112 plants (50.2 %), bushes – 102 (45.7 %), vines – 9 species (4.0 %) of the total number of species and forms. It is established that plants are derived from 20 floristic areas according to the floristic division of the world. According to floristic analysis, 55 species and forms (24.7 %) originate from the Atlantic North American, 48 (21.5 %) – East Asian and 40 (17.9 %) – Circumbres regions. The systematic analysis of tree species has revealed 2 leading families. Among largest quantaty of species is the Rosaceae family, which combines 21 species, which includes 51 species and the form and the family Fabaceae, which combines 10 genus with 13 species and forms. In the dendrological park there are also two relict species – Taxus baccata L. and Ginkgo biloba L. Without proper care many species and forms of plants and especially valuable bushes died and fallen out of the flora of the dendrological park.
