Custos de implanta??o e manuten??o da arboriza??o de ruas da cidade de Curitiba, PR

摘要

The aim of this research was to obtain the urban street trees costs in its different phases of development, using the street tree program of Curitiba as a study case. The tree value at age n was obtained by the sum of costs of tree implantation and maintenance, considering five cost centers: seedling production, planting and replanting, pruning, removal and planning and control. The costs were divided in nine species groups formed according to growing rate in the nursery and size. The species with the highest costs were those of slow growth rate in the nursery and large size. The valuation of a tree through its costs, which can be obtained at municipal institutions, is feasible and can be easily adapted to other Brazilian cities.
