A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. Not enough rain falls on a savanna to support forests.
Temperate grasslands are a division of a larger biome grouping of grasslands that includes tropical savannas. Both biome types are characterized by a dominance of grasses, yet temperate grasslands differ significantly from savannas.irst unlike savannas that can have trees and shrubs scattered throughout, temperate grasslands have trees and shrubs absent. Temperate grasslands are also found in less tropical ecosystems and thus have a larger temperate fluctuation during the year.
