Scientific name: Duffys Forest Ecological Community in the Sydney Basin Bioregion
Conservation status in NSW: Endangered Ecological Community
Commonwealth status: Not listed
Gazetted date: 28 Jun 2002
Profile last updated: 17 Mar 2023


Open-forest or woodland community dominated by Red Bloodwood Corymbia gummifera, Black Ash Eucalyptus sieberi, Smooth-barked Apple Angophora costata, and frequently a stringybark E. capitellata or E. oblonga. Other understorey species include Myrtle Wattle Acacia myrtifolia, Hairpin Banksia Banksia spinulosa, Rusty Velet-bush Lasiopetalum ferrugineum, Crinkle Bush Lomatia silaifolia, Broad-leaf Geebung Persoonia levis, Apple–berry Billardiera scandens, Wiry Panic Entolasia stricta, Twisted Mat-rush Lomandra obliqua, Micrantheum ericoides and Xanthorrhoea media.


Extensively fragmented distribution, occurring primarily within the Warringah part of the Northern Beaches, and Ku-ring-gai Local Government Areas (LGA) with minor occurrences in the Pittwater (Ingleside and Bilgola Plateau), Manly (Seaforth Oval) and Hornsby (South Turramura and Epping North). Estimated original extent was approximately 1450 ha, of which less than 16%, or approximately 240 ha, remains.

Habitat and ecology

  • Occurs in association with shale lenses and lateritic soils in Hawkesbury Sandstone. Rock outcrops are usually absent from this community, except on the fringes, where it adjoins typical sandstone vegetation, generally characterised by extensive sandstone outcrops.
  • Situated on ridgetops, plateaus and upper slopes, but may also occur on mid-slopes or benches downslope of Sydney Sandstone Ridgetop Woodland.
  • Occurs on Somersby, Blacktown, Lucas Heights and Lambert Soil Landscapes and, to a lesser extent, the Gymea and Hawkesbury Soil Landscapes.
  • Floristic composition and structural diversity is influenced by the size and disturbance history of the site.
  • Fire severity and frequency are important factors influencing community composition.
