Diagnóstico silvicultural da Universidade Estadual do Oeste do Paraná Campus Cascavel

Abstract

It is of great importance to the preservation and maintenance of green areas and urban trees to improve the environment and the urban population quality of life. The objective was to perform qualitative and quantitative diagnosis of afforestation of UNIOESTE (State University of Western Paraná) Cascavel campus through silvicultural inventory. Each tree is individually assessed, the identification was at the level of species or botanical family when possible. Quantitative parameters raised the camp were: (DBH)> 5 cm, total height of the tree, four crown radii (r). To measure the diameters metric caliper was used for determination of tree height and crown radii, use was made of Measure Heights® application. Through the DAP it was possible to calculate the basal area (g), and the average of the four crown radii (r) measured obtained the crown projection area (Ac). Qualitative parameters analyzed in the individual trees were as follows: Existing pruning type; Mechanical injury; Quality pantry; Quality trunk; Plant health; Ecological interactions and need for future management. The tabulation, data analysis, calculations and the preparation of charts and tables was made with the help of Office® Pack software (Microsoft Excel 2010). They were found and measures 217 trees, the majority native, distributed in 25 species belonging to 15 botanical families. The family with the largest number of individuals was Fabaceae, the most abundant species was Sibipiruna. According to the figures in the short term the traffic routes and parking areas will be able to further benefit from the natural shade of the canopy of existing trees, and the possible extension of the wooded area. In general, the qualitative condition of trees is good. However, some problems were detected with regard to the maintenance of the trees. Still, the arboreal heritage has much potential to evolve and expand favorably, contributing to improving the quality of life of people who attend the campus. These trees collaborate to local biodiversity, creating ecological corridors and shelters particularly for birds.
