The classified forests of Benin, whether legally protected or traditionally protected, are still under severe pressure. This study object is the evaluation of the degradation of the classified forest of Tchaourou. This Landsat satellite image of 1990, 1999, 2009 and 2019 were used for diachronic analysis and the topo-sequential analysis. The results obtained show that the mosaic of field and fallow in addition to the tree and shrub savannah recorded a growth rate of 21.85 % and 32.05 % respectively for the period from 1990 to 2019. As for the woodland and savannah woodland, it experienced a regression rate of -39.96 %. The gallery forest also fell by -13.94 %. The explanatory factors for this deterioration of the different units of land use are, among others, agriculture, logging, late wildfires, grazing.
