Scientific name: Quorrobolong Scribbly Gum Woodland in the Sydney Basin Bioregion
Gazetted date:

Description
Quorrobolong Scribbly Gum Woodland is a low shrubby woodland with the overstorey dominated by Eucalyptus racemosa (Scribbly Gum). Other tree species present include E. piperita (Sydney Peppermint), E. resinifera (Red Mahogany), Angophora costata (Smooth-barked Apple) and E. punctata (Grey Gum). There is usually a well developed shrub layer with common species being Leptospermum trinervium (Slender Tea-tree), Acacia parvipinnula (Silver-stemmed Wattle), Persoonia linearis (Narrow-leaved Geebung) and Leptospermum polygalifolium (Tantoon). The ground layer is often sparse and frequently occurring species are Imperata cylindrica var. major (Blady Grass), Panicum simile (Two-colour Panic), Pratia purpuracens (Whiteroot), Lomandra cylindrica (Needle Mat-rush) and Dianella revoluta.
Distribution
Currently known from only a small area between Quorrobolong and Mulbring in the Cessnock local government area, but may also occur elsewhere within the Hunter Valley. The current known extent is about 70 hectares; the pre-European extent is estimated to have been only 160 hectares, reflecting the limited area of the sand deposit on which it occurs. Not known to occur within any conservation reserves.
Habitat and ecology
- Occupies gentle slopes and rises on a residual sand deposit overlying the Permian clay sediments of the Hunter Valley floor.

Threats
- Highly restricted distribution with no part of the community occuring on secure tenure.
- Clearing and loss of vegetation including inappropriate land use
- Habitat degradation from grazing and weed invasion.
- Inappropriate fire regimes.
- The community is susceptible to extinction from random natural and human-induced events because of its very limited extent.
