Scrub

 

thickets of xerophytic, mainly evergreen shrubs found in arid regions of Australia. The shrubs reach a height of 2 m. Prevailing species are scrub eucalyptus, acacia, casuarina, and stunted shrubs of the families Fabaceae and Myrtaceae. The vegetation is characterized by xerophytic structure. The stiff foliage is generally gray-green with a waxy bloom; often there are phyllodes or thorns instead of leaves. The herbaceous covering is poorly developed, consisting of tufted grasses, annual strawflowers, saltworts, and some succulents.

In the most arid regions scrub eucalyptus is common (malee scrub). Regions having an annual precipitation of 150–250 mm are marked by a predominance of various acacia species (mulga scrub). In the tropical and somewhat more humid zone, brigalow acacia predominates, and sometimes eucalyptus and bottle trees are encountered (brigalow scrub).

Scrublands are also found in Africa.
