The Dendroflora Ecological Characteristics of the Park “At Brailky” (Poltava Town)

In populated areas, green spaces, particularly trees, are extremely important for creating a comfortable, safe and healthy living environment. Successful urban greening directly depends on the proper selection of plant species. Not all species are suitable for urban environments, where soils are often polluted and the air is saturated with harmful emissions from industrial enterprises, cars and dust. Therefore, species that are resistant to stress factors such as drought, gas pollution and frost should be chosen for landscaping. The article analyses the results of the dendroflora study of the park “At Brailky” in the town of Poltava. The species composition includes 18 species with a total of 208 individual plants. The majority of the dendroflora belongs to the division Magnoliophyta, comprising 90% of the total. Trees dominate in terms of life forms – 16 species, while shrubs are represented by only two species. The ecological requirements of woody species were analyzed in relation to environmental factors such as light, temperature, moisture availability, and soil fertility. Based on light preference, the cultivated species were divided into two groups: shade-tolerant (56%) and light-demanding (44%). Regarding moisture, the majority of species are mesophytes (83%), followed by mesoxerophytes (11%) and xeromesophytes (6%). In terms of soil fertility, over half of the species (56%) were classified as mesotrophs. Most of the species (89%) are frost-resistant. The species diversity was assessed using the Margalef index, which was calculated as 3,18, indicating a moderately high level of species richness in the park’s dendroflora. The study highlights the significant ecological and valeological role of dendroflora in forming favorable conditions for life in residential and public areas, providing recreation opportunities, purifying the air, and reducing noise and vibration pollution.
