The effect of different types of land management on the soil macrofauna of the savanna has been assesed using the TSBF method. Macrofauna of the forest and savanna has a high density (4293 and 2830 ind. m (2)) and moderate biomass (13.6 and 15.3 gm (-2)). Traditional grazing significantly increase earthworm biomass but does not modify biomass (16.8 gm (-2)) and density (1971 ind. m (-2)). Burning the savanna leads to a momentarily but important disruption of the soil fauna. After 6 months, soil macrofauna has regained its
