The city is to start planting palm trees again this summer following a ten year period without planting any, due to infestations by palm weevils. Six different pest-resistant species will be used, with a total of 117 trees to be planted around 30 different locations.
The new palm trees will be planted at 30 different locations in the city, in streets, squares and parks, including Passeig Colom, Rambla de Poblenou, Plaça Central de Nou Barris and Turó Park. Six species have been chosen which are resistant to infestations from species such as the palm weevil, which has caused the loss of 500 palm trees since 2006 and which prompted the ten year period when no palm trees could be planted. Now the infestations are under control and have been reduced drastically, 117 new trees will be planted. The campaign starts now and will be completed in the next few weeks.
There are currently 10,924 palm trees in Barcelona. Most of them, 62%, are in the districts of Ciutat Vella, Sant Martí and Sants-Montjuïc, with 19 different species in all. Of these, 80% are date palms, Canary Island date palms, Mexican fan palms and California fan palms.
Palm trees are highly appreciated for their appearance, height and presence in iconic places. The tallest recorded palm tree in Barcelona is 27 metres high and is located at Can Verdaguer, in the Porta neighbourhood in Nou Barris. The oldest specimens date back to the beginning of the 19th century. The location of these trees can be found in the catalogue of trees of local interest.
