The article presents the results of the sensitivity of phenological rhythms of woody plants to spring temperature fluctuations in urban environments, using the city of Voronezh as an example. Phenological monitoring of the pendulous birch (Betula pendula R.) was used as an experimental species. Based on 4-year (2021–2024) phenological observations at eight model sites, a tendency towards a shift in the timing of the phenological phase of leaf unfolding was identified. The aim of the study is to identify the pattern of the influence of spring temperature fluctuations on the phenology of woody species. The research results demonstrate that the pendulous birch can serve as an indicator of early spring temperature fluctuations.
