Structura, diversitatea si starea de sanatate a vegetatiei urbane in Bucuresti: un studiu de caz bazat pe aliniamente

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