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.


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.
