What this project protects
The Orchard Trail site being so unique protects a number of rated species. This includes an extensive population of native raspberry (Rubus parvifolius), rated as rare in the Adelaide Hills, and a colony of Austral indigo (Indigofera australis), which is rated as near threatened in the Mount Lofty Ranges. This area is a haven for birds in the hotter months.
The Quarry track area of the project site has been extensively modified in the past by the quarrying activity. It lies at the base of a small silver banksia (Banksia marginata) woodland on the Yurrebilla trail and includes a soak which has a population of the rare woolly tea tree (Leptospermum lanigerum). The northern slopes of the Yurrebilla trail have a high quality herbacious understory and it includes many clasping goodenia (Goodenia amplexans) which is plant endemic to South Australia.
