%X Remnants of vegetation in urban perimeters provide better environmental conditions to local biological diversity and quality of life for the population. The objective of this study was to appraise the Vegetation Cover Index (VCI) of urban perimeter of Erechim, Rio Grande do Sul for the years of 2010 to 2015. Mapping was carried out by means on high-resolution satellite images and with the support of Geographic Information System (GIS). The results of this study showed a reduction of 229.98 hectares of vegetation area. This reduction is mainly associated with increased urbanization through allotments encouraged by public housing policies. A future scenario for Erechims urban area shows a tendency to reduction of the vegetation cover, unless new projects to encourage the maintenance and conservation of these urban forest remnants. The VCI of Erechims urban perimeter reduced 3.23%, being that for the year of 2015 this rate was 28.40%. About the total of 58 districts: 36 keep their stable VCI; 19 districts reduced their VCI; and 3 districts increased their VCI. Expansion of urban areas, besides of reduce the vegetation, contributed effectively in the disorderly occupation of the city, generating negative impacts on environment and consequently in the quality of life for the local population.
