The forest‐savanna contact zone of South‐Eastern Cameroon is a dynamic environment developped on a lateritic cover. This area is subject to various modifications, the most remarkable being the forest overgrowing on the savanna. The phenomenon is usually considered as a linear process and as a result of climatic factors. In fact, this process occurs by zonal transformation of the savanna into forest through intermediary textural savanna units. Such evolution is controlled by the nature and the distribution of soils, water dynamics and climate.
