Wilcox bush (Eremophila forrestii) 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

The absence of wilcox bush in wanderrie and hardpan mulga country can indicate poor pasture condition. The class of livestock being managed and local palatability of wilcox bush will determine its usefulness as an indicator plant. When readily consumed by livestock, it is considered desirable and decreases under heavy grazing. Wilcox bush has no value as an indicator when it isn’t grazed. Heavy grazing of wilcox bush indicates a feed shortage.

Forage value

Wilcox bush varies considerably in palatability for sheep and is not a preferred feed for cattle. It is an important forage shrub in the Gascoyne coastal plain, in wanderrie country and in hardpan mulga country. 


Sandy soils, hardpan, limestone
