Abstract: Fire is one of the main modeling agents of savanna ecosystems, affecting their distribution, physiognomy and species diversity. Changes in the natural fire regime on savannas cause disturbances in the structural characteristics of vegetation. Theses disturbances can be effectively monitored by time series of remote sensing data in different terrestrial ecosystems such as savannas. This study used trend analysis in NDVI (Normalized Difference Vegetation Index)-MODIS (Moderate Resolution Imaging Spectroradiomete… Show more

“…The different groups of communities proposed for the Luso-Extremaduran province occupy areas whose dominant ecological factor is the xericity of the substrate. These are edaphoxerophilous formations with a permanent character that occupy restricted areas, but are currently in expansion, as frequent fires and the deforestation and clearing of the scrub layer have led to an extension of eroded areas due to soil loss: indeed, the absence or presence of fire is the main agent of vegetation change in areas with low anthropic influence [55]. These biotopes do not tend to be occupied by Fagaceae, and the forests of Quercus ilex subsp.…”

“…The MODIS MOD13Q1.006 Terra Vegetation Indices 16-Day Global (Didan, 2015 ) was used to calculate the Normalised Difference Vegetation Index (NDVI) for the time-period 01/01/2001 to 31/12/2020, corresponding to the fire data archive. NDVI is a widely used index for detecting fire risk potential (Michael et al, 2021 ), fire recurrence (Santana, 2018 ) and fire recovery (João et al, 2018 ; Lacouture et al, 2020 ). The NDVI time-series are particularly useful for assessing the spatial and temporal dimensions of fire (Michael et al, 2021 ; Santana, 2018 ).…”

The NDVI time-series are particularly useful for assessing the spatial and temporal dimensions of fire (Michael et al, 2021 ; Santana, 2018 ). The MOD13Q1 V6 product provides a vegetation index value per pixel, with a 250 m resolution (Didan, 2015 ).…”

“…Após a década de 70, na região pantaneira houve expansão da pecuária extensiva, cujo manejo fundamenta-se em uso intenso de mecanização, desmatamento e queima de biomassa para o aumento das áreas de pastagens provocando alterações de alinhamento dos rios, defasagem quanto ao período de inundação, erosões do solo, aumento dos incêndios orestais e focos de calor (Alvarado et al, 2017;Santana, 2018;Oliveira-Júnior et al, 2020).…”
