 Mulga country intersperses with other vegetation such as spinifex, dominated by low mounds of "Triodia", and wattle scrub (Mimosaceae) or interrupted by granitic outcrops, salt lakes, and desert.The mulga itself is a mid-sized tree that is usually well-established in the open woodland, only occurring as young plants in disturbed areas, and is typically around 8 metres tall.Stands of mulga trees are usually around the same age, eventually dying and replaced in a periodic regeneration cycle.
