The first comprehensive assessment was conducted to study the allergenic aeropalynodendroflora in the greening of the Left-Bank Polissia region territories, using the example of the city of Chernihiv, Chernihiv region (taxonomic composition, biomorphological, ecological structure, frequency of occurrence, distribution).Based on the original research results, we found that the allergenic aeropalynodendroflora comprises 82 species, 18 cultivars, 26 genera, 16 families (Magnoliophyta – 59 species, 19 genera, 14 families, Pinophyta – 23 species, 7 genera, 2 families). The most numerous in terms of species are the families Pinaceae – 12 species (Pinus (8 species), Picea (4), Cupressaceae – 11 species (Juniperus (5); among angiosperms – Salicaceae – 20 species (Salix (15), Populus (5)), Aceraceae – 8 species (Acer (8). The most diverse cultivars are Thuja occidentalis (7), Juniperus sabina (3), Acer palmatum (3). Frequency analysis revealed that 36 species are widespread; while representatives of 43 species are rare (most are found in collection sites). We identified the locations of species according to their distribution by different types of urban plantings, with 10 species found in all types of plantings and 22 species found in public areas as part of the greening structure. It was determined that trees are the dominant life form in plantings (65 species: deciduous (47), evergreen (18)). In terms of height, there was a predominance of trees of the I size (27 species) and bushes of the I size (8) was noted. It has been established that most species have a high adaptive capacity to the natural and ecological conditions of urban ecotopes, with a significant proportion being oligotrophs (41 species) in terms of soil demand; mesophytes (43 species) in terms of soil moisture; and heliophytes (39 species) in terms of light requirement.
