Mestrado em Engenharia Florestal e dos Recursos Naturais - especialidade de Floresta Urbana - Instituto Superior de Agronomia

This study aims at taking an inventory of trees, woods and forest stands, classified as being of public interest, in the Municipality of Lisbon and to know about the state of development and health of these trees. A survey was done of the potential of various samples, outstanding due to their size, location and rarity in the county, as well as of stands of native vegetation that stood out for their botanical, scenic and historical interest. Were inventoried thirteen arboreal formations including six forest stands within the Monsanto Forest Park, and seven sets of trees, located in Jardim Braamcamp Freire, Jardim Nuno Álvares Pereira, Praça de Diu, Largo Hintze Ribeiro, Parque das Conchas and Parque do Alvito. 204 trees were measured, belonging to the genuses Casuarina (five trees), Eucalyptus (twelve), Ficus (four) Quercus (118), Olea (eleven), Phillyrea (five), Pinus (eighteen), Tipuana (sixteen) and Zelkova (fifteen). Of the trees surveyed, 83% were judged to be performing well and in a good state of health, 7.8% had significant damage, 4.9 % were subject to a stressful health situation and 0.98 % had been subject to vandalism. Some of the tree stands showed problems in relation to both cultural and plant health issues.
