General Description

Yookamurra is gently undulating country with a minimum elevation of 80 m and a maximum elevation of just over 90 m.

Soils are thin (0 - 50 cm) and overlie a layer of calcrete, which varies in thickness from 30 cm to 6 - 7 m. The calcrete itself overlies a rubbly limestone. Soils vary from a reddish brown, sandy loam to fine rubbly limestone and deep residual claypans with soils up to 3.5 m in depth.

The sanctuary is dominated by Eucalyptus shrubland (mallee) communities and sugarwood communities.
