                         for the 2003 2007 period, considering regional watersheds 
                         (Ottobacias de n{\'{\i}}vel 3), the PROBIO remnant vegetation 
                         map, and change assessments based on MOD13Q1 NDVI (normalized 
                         difference vegetation index) imagery. Specifically, four time 
                         frames were taken into account: 2003 2004, 2004 2005, 2005 2006, 
                         and 2006 2007. Interestingly, these four periods are grouped into 
                         two major categories, with significant differences regarding the 
                         number of watersheds, the total converted area and the amplitude 
                         of the rates. For the overall period of 2003 2007, the 
                         deforestation rate varied from 0,03% to 9,78%, with a mean value 
                         of 1.59%. Large values are predominantly found in the watersheds 
                         located in two hydrographic regions, while hydrographic regions 
                         mostly situated in the southern portion of the biome show the 
                         lowest rates. Although it is possible to devise consistent spatial 
                         and temporal patterns, our results also suggest that any attempt 
                         to model future scenarios for the Cerrado biome based on these 
                         highly variable deforestation rates may induce in major mistakes.
