Monitoring of the floristic diversity of the Teremky Tract of the “Holosiivskyi” National Nature Park in the conditions of anthropogenic load

The article presents the results of monitoring the floristic diversity of the Teremky Tract, which is part of the “Holosiivskyi” National Nature Park as a separate territory. The tract is located in the city of Kyiv, directly adjacent to a large residential area and two highways. An analysis of the main factors affecting the ecological state of the territory was conducted. Among the main factors negatively impacting the state of the ecosystem of the Teremky Tract, the following can be distinguished: vandalism, which includes setting fire to old trees and causing various types of damage to them; plucking of flowering plants; environmental pollution with solid household waste; direct and indirect influence of hazardous objects such as boiler plants and gas stations; and the influence of transport infrastructure. The article demonstrates the need for constant monitoring of the ecological state of natural biotopes located within modern megacities. It is shown that the monitoring of floristic diversity, controlling the preservation of valuable and rare plant species, and tracking the appearance and spread of invasive alien species can be effective indicators of the ecological state of the natural biotope. Thus, populations of forest lily (Lilium martagon L.) and cuckoo’s tears (Listera ovata L.) were found on the territory of the Teremky Tract, which are included in the Red Book of Ukraine. Additionally, a group of 400-year-old oak trees grows in this area. However, the presence of invasive alien species such as red oak (Quercus rubra L.), the ash-leaved maple (Acer negundo L.), black cherry (Prunus serotina L.) and Robinia pseudoacacia L. was also observed. Monitoring of floristic diversity in natural biotope areas within megacities plays an important role in timely response to the effects of negative natural and anthropogenic factors for the preservation of the environment of these urban ecosystems. Such monitoring can be conducted both through field observations and using remote methods and analysis of global biodiversity databases such as iNaturalist and GBIF.
