| In order to improve the management of the urban tree health in Madrid, a sample of 49 green spaces was evaluated. Data were obtained by visual assessment in 6 different districts of the city, during a period of 3 or 4 years. Diseases, pests and other problems were collected from each species in every green area, without considering the number of trees. The health status of the trees declined along the period and there were few differences among the districts. Main problems in trees were stem injury, dead branches, epicormic shoots and decay, and the most damaged species were Siberian elm IUlmus pumifa} , Black locust (Robinia pseudoacacia), Box elder (Acer negundo), and Plane tree IPlatanus x hispanica). Decay was related with stem injUry. Biotic diseases were encountered less frequently than abiotic, and they affected a smaller rank of species. | |
