Análise da arborização de acompanhamento viário em uma cidade de pequeno porte : Luiziana, Paraná

Abstract

The lack of planning for urban forestry presents problems for government and population. Inventory are indispensable tools for the management of this infrastructure. The main objective of this study is the analysis of urban tree in a small town, located in the Northwest Region of Paraná, Luiziana, which has 4,350 inhabitants. We chose to work in a city with these characteristics, because there are few studies that addres the issue in these areas. The study used qualitative and quantitative inventory, in order to characterize the trees observed in the field. The city as good urban forestry distribution, but a down species diversity. Are 65 species in 3030 individuals, the most common species are Ligustrum lucidum (Ligustro), Schinus molle (Chorão), Caesalpinia pluviosa (Sibipiruna) and Murraya paniculata (Murta), the four species represent 72, 15% of individuals presents in the area. The specie most frequent problems in the city were poorly made pruning and problems related to obstruction of the pavement, caused by plant roots. The urban forestry presentation problems with curse and disease, 28% in the trees be affected. The specie that presented the greatest problem with the urban infrastructure and plant health was Ligustrum lucidum. According to the points raised in the field, it is suggested to arborization, measures guiding the management of existing species and a suggestion to the species with potential use in urban forestry.
