Avaliação de árvores urbanas no 1º Colégio da Polícia Militar do Ceará General Edgard Facó

Abstract

The Colégio da Polícia Militar do Ceará was created on March, 1997 under the purpose of a quality education to society. Several factores influence the activities performed and the environment, including urban afforestation. The afforestation has significance in the urban and in the quality of the environment. The work had as its objective to understand the process form of the afforestation of CPMCE, observing the trees’s dendrometry, besides the risk factors found. The obtained results showed that there were problems related to dry branches, irregular pruning, outcropping of roots, termite (Isoptera), cradle area, proximity to the power grid, and more. The collected data was compiled and inserted into a table, and it was detected that there is an inadequate management of the arboretum. Irregular pruning can leave the door open to the introduction of phytopathogens. For this reason, it became necessary to know "in loco'' the school’s wooded area, analyze the species, quantify and identify the risk factors and then propose viable solutions. It had been studied 18 tree species, a total of 75 trees, besides cataloguing approximately 10% of the Azadirachta indica A Juss species (Nim indiano) and 3% of Pithecellobium dulce (Mata-fome) for being exotic plants and having characteristics that make them invaders. Studies show that Nim indiano has a high toxic capacity in many degrees of pollen on European bees (Apis mellifera), being yet unknown its toxic potential on the species of natives bees. In this way, the plantation of these species must be avoided, exchanging them for native species. At the CPMCE there is only one specimen of native plant, the Munguba (Pachira aquatica Aubl), being advisable for the expansion of native species.
