Resumo
Na atualidade, a concentração populacional verifica-se nos grandes centros urbanos e o extenuante ritmo citadino contribui para a redução significativa da qualidade de vida dessas populações, que vivem com reduzidas ligações à natureza e com um maior contacto com as infraestruturas cinzentas, resultando na impossibilidade de usufruirem dos benefícios que a ligação com os espaços verdes oferece. É neste contexto, que é cada vez mais importante valorizar as florestas existentes nas nossas cidades, com vista a potenciar todas as vantagens das mesmas, para o equilíbrio entre a vida urbana e o mundo natural. A floresta urbana constitui um refúgio natural e oferece inúmeros benefícios tanto a nível ambiental, como económico e social. Contudo esta pode constituir focos de perigo causando danos em pessoas e bens, devido a quedas de ramos, pernadas ou mesmo da própria árvore. Baseada nestas ocorrências, é sublinhada a importância da avaliação fitossanitária e do risco de fratura de árvores, e a posterior manutenção e medidas de intervenção nas mesmas para assegurar a longevidade, estabilidade e saúde das árvores em ambientes urbanos. Neste relatório, para além de referidas as vantagens associadas à presença de árvores no mundo citadino, assim como os problemas relativos à saúde da árvore, é apresentada a metodologia usada para a avaliação de árvores em contexto urbano, e são apresentados casos de estudo em floresta urbana no norte de Portugal.
Nowadays the population concentration occurs in urban centers and the strenuous city rhythm contributes to the significant reduction in the quality of life of these populations who lives with reduced links with nature and with greater contact with grey infrastructures resulting in the impossibility of enjoying the benefits that the connection with green spaces offers. In this context it is increasingly important to value the existing forests in our cities in order to enhance all their advantages for the balance between urban life and the natural world. Urban forests are a natural refuge and offer numerous benefits both environmentally and economically and socially however these can be outbreaks of danger causing damage to people and property, due to falls of branches or the tree itself. Based on these occurrences the importance of phytosanitary assessment and the risk of tree fracture and subsequent maintenance of trees is stressed to ensure the longevity, stability and health of trees in urban environments. In this report, in addition to mention the advantages associated with the presence of trees in the city world as well as the problems related to tree health, the methodology used for the evaluation of trees in an urban context is presented with cases studies in urban forests in northern Portugal.
