    The Gurupi Biological Reserve is an integral protection conservation unit in the Amazon, sheltering endemic and endangered species altered to serve economic interests. Furthermore, continuous deforestation puts the occurrence of forest fires at constant risk. Thus, this master's thesis consisted of understanding the dynamics of fire in different ages of secondary forests, verifying fire's temporal and spatial dynamics and its relationship with climatic variables and with land use and land cover in the interior of Rebio and its area, as a subsidy for the conservation of biodiversity in the region. Thus, the Mann-Whitney test was performed to test the hypothesis of a difference in fire occurrences inside and around the Rebio and use the Google Earth Engine to process data from 2012 to 2018. The results showed that in 2016, 85% of fire ignitions were found to occur in forest cover, evidencing arson fire and not escaping from adjacent areas. On the other hand, an average of 81% of the ignitions took place inside Rebio, while 19% came from the surrounding area. It is understood that this study identifies priority areas for prevention activities since it explicitly identified the forest areas that were already affected by fire and, therefore, are more susceptible to new fires.
