I am from Africa and obviously enjoy this game a lot so here is some suggestions that I am convinced will brighten up user enjoyment of the RW Savanna biome more. There are so many things one can look at if one wants to add aditional wildlife / plants etc to the biome but I tried to keep this list to just a few important items Africans pride themselves in 
African / Savanna Bioma Suggestions:
Animals:
African Lion
Cheetah
Springbuck - (Groupe antelope - National animal of South Africa)
Gemsbok / Oryx (Group antelope) is another important feature of the African continent)
Kudu
Birds:
Ostrich (Cannot fly)
The ostrich lay eggs almost the size of a rugby ball that are also good for foodfor predators like the african baboon and humans
Blue crane (South Africa's National bird)
Plants - Non-edible
Pachypodium namaquanum (Know in my country as Half-mens / Half-Human)
The King Protea (South Africas National flower)
Plants - Edible
Bi-Bulb Plant (Water holding root / bulb)
Used for drinking water and bathing... See video in the link hereunder:

(Edit) I forgot to add one of the most important trees on the African continent 
Trees
The Marula tree
This tree serves the animal population in various ways and one of its best uses is its fruit, the Marula fruit which is use to make alcoholic drinks for the international market. On a fun note every year when the fruit falls to the ground the animal eat these fruit and it ferments in their stomachs and voila we literally have drunk animals for a day or 2 until all the fruit has been eaten
The effect of this can be seen in a movie by Jamie Uys called Beautiful people.
