Gis-Based Inventory of Street Trees as a Tool for Managing Urban Green Infrastructure in Chernivtsi

This paper presents the results of a study of street tree plantings in the central part of Chernivtsi, aimed at developing approaches for creating a GIS-based electronic inventory to optimize urban green infrastructure management. An inventory of 446 trees across eight streets in the historic city center revealed a predominance of native species (67.3%), including Tilia cordata, Acer platanoides, and Fraxinus excelsior, alongside the presence of invasive species (28.9%), such as Acer negundo and Robinia pseudoacacia. The methodology included route surveys, instrumental measurements of morphometric parameters, and qualitative condition assessments using a three-point scale. The results showed that 73% of the trees were in good condition, 23% in fair condition, and 4% in poor condition, with notable damage to Aesculus hippocastanum caused by the horse-chestnut leaf miner (Cameraria ohridella). The study substantiates the need for GIS-based tree inventory as an effective tool for managing the city’s green infrastructure. An interactive database containing information on 8,538 trees across 82 sites was developed using the Cvtrees platform and integrated into the city’s geographic information system. The spatial integration of the collected data enabled not only the visualization of the current state of urban greenery but also the analysis of its distribution, condition, and renewal needs. The proposed approach supports improved monitoring, informed decision-making, and long-term planning of urban greening initiatives.
