Recorrências dos incêndios na vegetação do Parque Nacional da Chapada Diamantina-Ba, entre os anos 2000 e 2016

Abstract

Forest fires are a threat to biodiversity conservation especially in Conservation Units. The Chapada Diamantina National Park, guardian of great natural riches, is among the UC's of Brazil that have more fire. Remote sensing together with geographic information systems are important tools for the monitoring and detection of forest fires due to the ease and accuracy in obtaining information. The objective was to characterize and map the fires in the Park between 2000 and 2016, in the environmental variables: vegetation, soils, altimetry, slope and proximity of trails and roads. The fire areas of each year were mapped and then added to the overlap for frequency information and last year's burning. Vegetation of the rock field type presented higher incidence of fires and higher frequencies of fires. Licholic neosols presented large numbers of fires and areas with higher frequency of fires, as well as distant sites of trails and roads, much due to the difficulty of access to initial fire fighting. It is concluded that the mapping and survey of information on the frequency and characteristics of fires is fundamental for the creation of prevention and fire-fighting strategies in the Chapada Diamantina National Park.
