Scientific name: Pittwater and Wagstaffe Spotted Gum Forest in the Sydney Basin Bioregion
Gazetted date:
22 Feb 2013
Profile last updated:
07 Sep 2017
Description
General structural form is open-forest but may now exist as woodland or remnant trees. The tree canopy layer is characterised by Spotted Gum Corymbia maculata and Grey Ironbark Eucalyptus paniculata and is associated with Smooth-barked Apple Angophora costata, Red Bloodwood Corymbia maculata, Broad-leaved White Mahogany E. umbra, Grey Gum E. punctata, Turpentine Syncarpia glomulifera, Bangalay E. botryoides, and Rough-barked Apple Angophora floribunda.
Distribution
Occurs entirely within the Pittwater Local Government Area, on the Barrenjoey Peninsula and Western Pittwater Foreshores. Remnants are typically small and on private property, however there are a few remnants in Council reserves and one remnant within Ku-ring-gai Chase NP.
Habitat and ecology
- Occurs in association with shale derived soils with high rainfall on lower hillslopes on the Narrabeen Group - Newport Formations on the Barrenjoey Peninsula and western Pittwater Foreshores.
- Assemblage diversity must take into account species likely to be present in the soil seedbank.
- Structural form is typically open-forest but may now exist as woodland or remnant trees.
- Floristic composition and structural diversity influenced by the remnant size, disturbance history and fire severity and frequency.

Threats
- Habitat loss and degradation due to urban development including encroachment.
- Encroachment from urban areas including illegal and legal tree and understorey removal, planting of exotic species and weed invasion.
- Inappropriate fire regime being a combination of lack of fire and too frequent fires due to arson and hazard reduction burns.
- Stormwater and soil erosion.
- Disturbance from recreational users, including unauthorised visitor access; rubbish dumping, illegal trails, illegal mountain bike tracks, and walkers.
- Introducing and spreading of disease including phytophthora and myrtle rust.
- Weed invasion, including multiple asparagus species, mickey mouse weed, bitou, privet, crofton weed, lantana, mixed woody weeds and garden escapes.
- Lack of knowledge about extent, composition and condition beyond the areas mapped for this toolbox.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Remove rubbish.
- Control stormwater and soil erosion.
- Introduce measures to control unrestricted access and/or inappropriate use.
- Manage weed infestations.
- Protect areas of habitat from clearing and further fragmentation.
- Restore degraded habitat using bush regeneration techniques.
