We adopted this criterion because phenotypic plasticity is a common phenomenon in woody savanna species, which makes the distinction. How habitat loss and fragmentation are reducing conservation opportunities for vertebrates in the most threatened savanna of the World. Water is often scarce in Africa's savannas, so it would seem logical to conclude that more rainfall would allow the few trees in the expansive grassland. Evolutionary partitioning between Grassland, Savanna and Forest is supported suggested by low introgression of Biomes at family and genus level, and by a dominance of life-forms adapted to open habitats environments. Not enough rain falls on a savanna to support forests. More rain leads to fewer trees in the African savanna.
