anglais. Street tree alignments are among the most common green spaces within urban areas. The aim of this study was to assess the interspecific variability and the degree of defoliation of the trees within street alignments situated along four of the most common boulevards from Bucharest, namely Kiseleff, Ştefan cel Mare, Virtuţii and Timişoara. The total evaluated distance was 17.6 km. 1621 trees were sampled and more than 30 taxa were recorded. Autochthonous species were more numerous, compared with the allochthonous ones, but the non-indigenous trees were better represented, mainly due to the large number of London plane tree, northern red oak and horse-chestnut. The most common autochthonous species were smallleaved lime, silver linden and narrow-leafed ash. Half of the species were large, reaching heights up to 25 m or more. All four boulevards were dominated by three species. Almost 80% of the trees were in good health and only 7% were almost dead. Several tree features in accordance with the conditions for establishment of future street tree alignments were discussed.
