Abstract
Vegetation has relevant functions in urban areas which comprises temperature regulation, maintenance of relative air humidity, shade, lessening of atmospheric pollution, preservation of land and water ecosystems, increase in urban permeability area, provision of leisure and recreation, softening the urban landscape and others. Due to the importance of the theme, current assay develops a Quality Index of Urban Green Areas (QIUGA) based on data produced by Ecological ICMS, and its application in 16 towns of the state of Paraná, Brazil, between 2000 and 2008. QIUGA comprises three sub-indicators: Green Areas Index (GAI), Percentage Index of Green Areas (PIGA) and Income Index with Ecological ICMS (IICI). Only the municipality of Pinhais PR Brazil had excellent green areas between 2000 and 2008, whereas Curitiba had good quality green areas. During most of the period, Araucária and Apucarana had bad quality urban green areas with other towns featuring very bad quality green areas. Results show that, as a rule, units of urban conservation are neglected by the public administration. Since they are not listed in official environmental organs, the towns have low index rates due to methodology used.
