Fires in vegetation are pointed out as one of the main factors that impact and threaten the conservation of biodiversity in environmental systems. In Brazil, in the state of Bahia, Chapada Diamantina is one of the most affected region by constant burning, requiring huge investment of financial resources to fight the fires. Hotspots data detected by satellite sensors have been used to identify areas of occurrence of fires. From these data, estimates are made about the possible location and extent of affected areas, highlighting the temporal / spatial dynamic of fires. This study aimed to analyze the spatial behavior of hotspots between the years 2000 to 2011 in the National Park of Chapada Diamantina, in order to identify the areas of greatest intensity of fire occurrence obtained with the aid of Kernel intensity estimation. To this end, was made a survey of georeferenced hotspots existing into the park, organized a database, and then, in a GIS environment, modeled the distribution pattern of the set of points. According to the analyzed data, about 439 hotspots were detected by sensors aboard NOAA satellites - NOAA 12 and - 15 in the last 12 years within the park boundaries. It was found that the year of higher incidence of hot spots in the park was in 2008, when 243 focuses were detected. The number of hotspots recorded in 2008 represents about 55% of the total. It was found that 245 of the 439 spots detected were in the east border of the city of Mucugê (about 56%).Pages: 6969-697
