Savannas are a transitional biome, not really a forest and not really a desert – just somewhere in between. Savanna, also spelled savannah, vegetation type that grows under hot, seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground). Grasslands, also known as prairies, steppes, or savannas, exhibit naturally dominant grass vegetation, typically in areas where there is not enough rainfall to support the growth of a forest but not so little as to form a desert. What is the difference between a savanna and a desert?
A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome.
