  1. 1Pixels selected using the frequency of fire detections from the FireCCI51 product for the period 2001–2019. The total number of fires detected per pixel was grouped into 3 classes (burnt once, burnt twice, and burnt thrice or more). For the first three rows, the percentages represent the area of each class within the Total area of each subregion (left) and the area of each class among the Total BA only (right). For the Total burnt and Unburnt rows, the percentages are based on the Total area of each subregion, while those of the Total area row are calculated from the Total area of the Full region column
