Values in square brackets represents the percent contribution of dry/wet miombo to M.
P the range of largest annual burned patches detected, may have aggregated with time during the fire season, A the range of the total area burned in dry/wet miombo as a percentage of the dry/wet miombo area with data, A _P the total area partially burned in dry/wet miombo as percentage of the total dry/wet miombo area with data, M the total area burned in miombo at the same time when A was recorded, as percentage of miombo area with data, RI Fire return interval observed for every 2,500 ha from Landsat satellite images.
^aBased on MODIS detected fires for every 314 ha for the period 2001–2013.
