                         tends to change if the human pressures, such as pasture and 
                         intensive fire, are suppressed showing a densification of the 
                         physiognomies throughout the time. Vegetation Index acquired from 
                         remotely sensed data has been a proper way to study and monitoring 
                         large areas, and the Normalized Difference Vegetation Index (NDVI) 
                         is one of the most used for this purpose. The aim of this study 
                         was to assess the dynamic of structural changes in protected and 
                         non-protected areas of cerrado vegetation using NDVI. For this 
                         purpose, three cerrado fragments in the state of S{\~a}o Paulo, 
                         Brazil, were evaluated for a 26 year time span from 1985 and 2011, 
                         being two of them protected against anthropogenic interference. 
                         Landsat 5 Thematic Mapper images were used and processed in 
                         ArcGIS. In the protected areas NDVI indicated that the vegetation 
                         followed the expected trend of changes for cerrado, with more open 
                         physiognomies tending to be denser throughout this period of 26 
                         years, whereas in the non-protected fragment the NDVI evidences 
                         human pressure, showing lower phytomass in 2011. NDVI showed to be 
                         efficient in detecting and monitoring changes in cerrado 
                         vegetation structure, and can be useful to study both, the natural 
                         dynamics of cerrado vegetation and the anthropogenic interference 
                         in protected areas.",
