Results of the dendroflora inventory and assessment of the plantations of the Tomylivskyi Park, a monument of landscape art

Abstract

A landscape assessment was carried out and the integral value of the plantations of the Tomylivskyi Park-Monument of Landscape Art of local importance was determined. According to the integral assessment, the plantations of the park's I and III sections are classified as particularly valuable, and II and IV sections as of limited value, which is explained by the presence of a slightly larger number of mistletoe-infested, dead and dry-top trees, as well as the spread of self-sowing invasive species. The landscape of the park corresponds to the first stage of recreational digression, as the area of roads, paths and grounds occupies less than 5 % of its territory. The high total recreational score of the Tomylivskyi Park-Monument allows it to be classified as the highest first class in terms of recreation. The taxonomic composition of the park-monument is represented by 76 species. It has been established that the Pinophyta division includes 8 species grouped into one class, one subclass, two orders, two families and 5 genera. The Magnoliophyta division includes 64 species, 2 hybrids, 2 cultivars, which are grouped into 47 genera, 22 families, 19 orders, 6 subclasses and 1 class. As a result of the inventory, it was established that currently there are 2446 woody plants on the territory of the Tomylivskyi Park-Monument, of which 596 are trees, 1843 are shrubs, and 7 plants have a tree-shrub life form. The average age of the greenery in the park is approximately 60–70 years. The first trees were planted in 1940. Among the trees, the most common are Robinia pseudoacacia L. – 96, Ulmus capriofolia L. – 72, Tilia platyphylos Scop. – 56, Celtis occidentalis L. – 38, Corylus colurna L. – 37, Acer platanoides L. – 36, which is 56 % of the total number of trees found in the park. 77 specimens of dead and dry-top trees that are drying out and have lost their decorative effect are to be removed. Sanitary pruning is required for 87 trees, which is 14.5 % of the total number of trees in the park. The main reasons for the deterioration of the sanitary condition of the trees in the plantations of the park are the invasion of Viscum album L.; changes in climatic conditions, in particular, a decrease in precipitation and a decrease in soil moisture reserves, which led to the loss of Betula pendula, Juglans cinerea L.; excessive tree density and competition between trees for light, moisture and mineral nutrients, which affects their weakening and pest damage (Picea abies (L.) H. Karst, Buxus sempervirens L.)
