Fire occurs frequently in the eucalypt forests of the plateaux around Sydney, and plays an important role in the breakdown of exposed sandstone faces. Burnt debris frequently forms small dams behind which sandy sediments are trapped and form microterraces. The microterraces are highly effective in trapping propagules of the regenerating vegetation. Accelerated erosion and litter decay on the forest floor is caused by the turning over of soil and rock by lyrebirds. As the average turnover of debris is about 63 tonnes/ha/yr, the feeding activity of lyrebirds is a significant geomorphic factor.-from Authors
