Simon will describe how plantings and thriving vegetation have been successfully established in the public spaces at Barangaroo.

For this project, commonly available recycled inorganic resources (crushed sandstone and recycled sand from building excavation) were combined with composted wood mulch screened from green garden waste collections and used to recreate a three-tiered replacement soil landscape for Barangaroo. The mulch layer or “O” (for organic) horizon would be analogous to the forest litter layer; the topsoil or A horizon, a well-drained sandy soil containing nutrients, organic matter and biological life and the Subsoil or B horizon, a well-drained water holding layer for root anchorage and moisture reserve. https://sesl.com.au/projects/barangaroo-headland-park/
