| Habitat notes | Native through tropical Africa. Occurs naturally in xerophytic grasslands, on sandy or clay soils, up to 1500m a.s.l. Androppogon gayanus has been declared an environmental weed in northern Australia, due to its ability to spread and generate intense fire. Excessive grass fuel loads alter the fire regime and savanna vegetation (Cook et al., 2005) |
