COMPLEX ANALYSIS OF SYSTEMATIC, AGE AND INVENTORY STRUCTURE OF AGE-OLD TREES OF CHERNIVTSI

Abstract

The systematic, age and inventory structure of age-old trees in the green space of the city of Chernivtsi is analyzed. Systematic analysis of the identified age-old trees and inventory surveys were carried out. The division of age-old trees according to the basic inventory parameters was carried out. 114 specimens of age-old trees belonging to 28 species, which belong to 2 divisions – Pinophyta and Magnoliophyta, 3 classes – Ginkgopsida, Pinopsida and Magnoliopsida, 13 orders, 16 families and 21 genera were found. It has been found that Pinaceae family is represented by the largest number of genera. It has been investigated that the Division Magnoliophyta, represented by a Magnoliopsida class , is characterized by a significant representation of all taxa as compared to the Division Pinophyta, especially at the species level. It has been found that 9 species of trees ( 32% of the total) belong to the Division Pinophyta and 19 species of trees (68%) belong to the Division Magnoliophyta. The ratio of Pinophyta to Magnoliophyta is 1 : 2,11. The index of species wealth of age-old trees in the structure of green space of Chernivtsi is calculated as rather high. It has been revealed that the investigated age-old trees are characterized by the predominance of specimens aged from 100 to 200 years, the second category (15 – 25 m) of height, and also by the predominance of plants with the trunk circumference of more than 300 cm and the diameter of 50 – 100 cm. The obtained results of systematic, age and inventory research should be used in the formation of registers of age-old trees of the city of Chernivtsi to ensure the organization of their effective protection and preservation in the structure of green spaces of the city, increase their esthetic and recreational functions.
