Typical tropical savanna in Northern Australia demonstrating the high tree density and regular spacing characteristic of many savannas. A savanna or savannah is a mixed woodland grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.
Savannas occur where there isnât enough rain to support a tropical rain forest, but there is enough to keep it from becoming a desert. There is usually a dry season and a rainy season in the savanna, with strong, hot winds in the dry season and enough rain in the wet season to flood low-lying areas. Some examples of savanna habitat are the East African plains, the South American pampas, and the open woodlands of northern Australia.
