► C. columellaris is widespread across Australia but sensitive to fire and herbivory. ► There is evidence of a chronic recruitment deficit in much of the arid zone. ► Regeneration in the tropics was variable, consistent with very frequent fire. ► By contrast there is very dense regeneration at some...
