Trees growing alone or in small clusters are also part of the savanna biome. This defense also allows the plant to survive fires because the root is undamaged and can regrow after the fire. A fire followed by a rain favours red oat grass since it increases its seed germination in conditions where others seeds die (FAO, 2011; Ghl, 1982).

Bermuda grass uses both above and underground stems and also seeding to reproduce. In Uganda, under continuous grazing, lower stocking rates (2.4 ha/head vs. 0.6 ha/head) resulted in higher live-weight gains (0.4 kg/head/day vs. 0.3 kg/head/day) (Harrington, 1973).

It is one of the largest trees on the planet, with trunks that are often 50 ft. wide, and heights of up to 85 . Red oat grass is a fire climax species, one of the first plants to grow after a fire, and all the more resistant to fire if it is burnt regularly and not overgrazed after germination (SANBI, 2011). It is highly palatable to livestock, especially when young (SANBI, 2011; Tothill, 1992). Its crude protein content is rather low, from 8-9% DM at the vegetative stage to 2-3% when mature. Because of the little rainfall in the region, there are just a few trees. This species is more common in grassland that is in good condition (not overgrazed), it is palatable to livestock and game.
