Here is a cool map of the biomes in southern Africa...
The original is at: http://www.sanbi.org/vegmap/images/biomes.jpg
from the South Africa National Biodiversity Institute.
The Limpopo area where I am planning to go is pretty much the orange area in the northern part of the map.
Orange stands for Savanna.
The green in grassland
the red is Nama-Karoo...and I have no idea what it is...I guess I should go and have a look one day.
The gross yellow is succulent-karoo.
