Kirrawee's protected areas of STIF are used to collect seeds that can be planted as street trees or on private property to assist in sustaining the biodiversity of the area and protecting the unique flora that provides habitat for native fauna. Kirrawee's STIF reserves are largely maintained by the local council and Bushcare volunteers from the community. The Sutherland Shire Council and Bushcare volunteers maintain a Plant Nursery that sells native plants sourced from local species, and its website includes a native plant selector that encourages locals to purchase and protect species suited to the local ecosystem.
