This paper presents results from a study focusing on species composition of woody plants on the territory of baseline institution of National University of Life and Environmental Sciences of Ukraine (Kyiv). An accurate description of systematic structure and taxonomic composition has been given. The life condition of woody plants are estimated.

Dendroflora of basic institution of NULES of Ukraine includes 122 species belonging to 66 genera, 32 families and 25 orders, 3 classes and 2 divisions by the evaluation of the taxonomic composition of green spaces.

Division Pinophyta represented by 15 species (12,3 % of total quantity), Magnoliophyta – 107 (87,7 %). The most numerous families (quantity of species) are Cupressaceae – 7 (5,73 % of the total number), Oleaceae – 9 (7,37 %), Rosaceae – 37 (30,33 %).

Analysis of the biomorphological structure dendroflora indicates about the predominance of deciduous – 107 species (87,7 %), compared with coniferous – 15 (12,3 %). The dominant life form is a group of trees – 58,2 %, shrubs constitute 41,8 %.

Established that 74,6 % of woody plants that grow on the territory of basic institution of NULES of Ukraine are categorized as "healthy plants". The category of "damaged" and "severely" included nearly 24 %.

Determined, on the territory of basic institution of NULES of Ukraine grows 13 species of gymnosperms plants listed in the IUCN Red List. Among them 11 species belong to the group of low risk (LR), one species (Metasequoia glyptostroboides) to groups of species which are under the critical threatened with extinction in the future (CR), one (Ginkgo biloba) to a group of species that are endangered (EN).
