The location of Jundiai-Mirim river basin, close to large urban centers and industrial parks, has contributed to the appreciation of their lands. Consequently, the region has an intense process of urbanization that resulted in an increasing environmental disturbance in the forest areas. Given the need to preserve existing natural vegetation, because the watershed is the source of water used to supply Jundiai, SP, this study evaluated changes in the environmental quality of the watershed forest fragments between 1972 and 2013. The environment quality was determined by evaluating nine indicators of environmental disturbance, obtained by techniques of Geoprocessing and integrated by Multicriteria Analysis. The results showed a constant tendency of deteriorating the environmental quality of natural vegetation between 1972 and 2013, attributed to the intense process of occupation of the watershed. It is concluded that: (a) urbanization and deforestation of natural vegetation were primarily responsible for changes in environmental quality; (b) there is a need to create public policies to preserve the natural vegetation in the watershed.
