Diagnóstico da arborização urbana provenientes de solicitações de poda e/ou supressão em unidades operacionais da COMPESA

Abstract

The operational units of Companhia Pernambucana de Saneamento (Compesa) do not carry an afforestation plan, nor a systematic diagnosis of this private urban forest. Due to this problem, this study aimed to carry out a floristic survey and qualiquantitative diagnosis of trees, which sought to identify the problems related to planting and interference with the structures and / or equipment of the units located in the Metropolitan Region of Recife - Pernambuco. The identification of these trees, carried out by pruning and/or deletion, resulted in the categorization of 82 individuals into 19 species, distributed in 11 botanical families. The most frequent species was Mangifera indica L., with 23 specimens, representing 32.92% of the sample. The Anacardiaceae family was the most present, consisting of Mangifera indica L. (74%), Anacardiumoccidentale (19%) and Spondiasmombin (7%). Most of the identified plants are exotic (65.85%) and fruitful (68.29%). Of the total 93.9% presented the need for corrective actions such as pruning, and 6.1% were cases of suppression. In case reports, mangifera indica L. (29.87%) was the most frequent species. Among the dendrometric variables analyzed, mean values of DBH and H were obtained, where it was found that 76.82% of the trees are medium-sized and all in the adult stage. The qualitative aspects of the front afforestation were: Upwelling of the roots above the ground (32.92%); crown balance (balanced crown - 63.41% and partially balanced - 36.58%), with no representation of trees with unbalanced crown; presence of termites (51.22% not observed and 48.78% observed); need only for maintenance such as pruning (57.32%) and conflicts with structures and/or equipment (42.68%). The Conditions of conflict include: 60% interfere with the electrical network and 40% conflict with other structures and/or equipment. These results point to the need of a strategic planning for the maintenance and conservation of the urban forest present in the company's units.
