Annual sorghum (Sorghum stipoideum) is one of many plant species found in the Western Australian rangelands. This page provides a summary of the plant's value for pastoralism. Pastoral lessees and station managers can use this information to assess pasture condition and trend.

Indicator value

Where annual sorghum is dominant, it indicates fair to poor pasture condition in most pastures. Annual sorghum is usually considered an intermediate species. It is initially an increaser when pastoral condition deteriorates but may decrease under very heavy grazing pressure.

Forage value

Annual sorghum is palatable to livestock when it is young, but becomes unpalatable when it is mature and has very little bulk.


Various loamy, sandy and rocky soils.
