The authors assess the effect of poor grassland and forest management on the present state of the herd and ligneous stands. Cattle production has dropped considerably: 13 kg of carcass per animal per year and 300 litres of milk per lactation resulting from later precocity, lower fecundity and smaller size of females, and increased calf mortality. Wood volume has decreased, averaging 8.67 steres per hectare. Mean stem diameter is approximately 5 cm. The three main species, Combretum micranthum G. Don, Combretum nigricans Lepr. ex Guill et Perr. and Guiera senegalensis J.P. Gmel regenerate actively.
