The soil in the savanna is covered by a thin layer of hummus, soil made up of decomposition of dead plants and animals. There are 6 different types of soil found in the savanna:

- lithosols

- lateritic soils

- cracking clays

- red/yellow earths

- deep sands

- alluvial soil

Succession is a change in which a series of communities are established and over time replaced.

Primary succession is when an area that once contained no life at all, suddenly is filled with life. Secondary succession is when an area has life that is destroyed, and then recreated. There has been some secondary succession studied in the savanna biome.

Succession is a great example of dynamic equilibrium. It shows that over a big period of time, much can change. But in a little amount of time, equilibrium occurs.
