What Barcelona lacks for in parks and green area, it partly makes up for with its trees, particularly those plants along the city’s streets.
According the Council there are:
- More than 151,000 trees on the city’s streets and avenues. Sant Martí and the Eixample, with 30,788 and 22,090 trees respectively, are the districts with most trees in Barcelona. In the rest of the city -with the exception of Ciutat Vella and Gràcia, which have an urban structure that makes planting difficult- there are approximately 12,000 to 15,000 street-lining trees.
- There are 141 species of street- lining trees in Barcelona. 11 main species represent 77% of the total number of specimens. The most common is the London plane (Platanus x hispanica), with 50,000 specimens. These are followed by the European Hackberry (Celtis australis), with 18,460 specimens and further behind -with between 8,000 and 4,000 specimens – by the Japanese pagodatree (Sophora japonica), the Lombardy poplar (Populus nigra ‘Italica’), the elm (Ulmus pumila), the tipuana (Tipuana tipu), the black locust (Robinia pseudoacacia), the bottle tree (Brachtchiton populneus), the chinaberry (Melia azedarach) and, with fewer than 4,000 specimens, the glossy privet (Ligustrum lucidum) and the box elder (Acer negundo).
