Threats and preservation

Seasonal cultivation and herding are lifestyles which lead the population of the savanna to overgraze, overharvest the trees for firewood or charcoal and cause fires. This has reduced the woodland considerably. However large areas of unspoilt habitat remain even outside protected areas, especially compared with the more heavily populated West Sudanian savanna. Poaching is another problem, indeed the
