The heathy understorey contains shrubs ofSannantha collina and Lemon-scented Tea-tree (Leptospermum petersonii) over a ground cover of Kangaroo Grass(Themeda australis).ExoticsSpecies richnessAndropogon virginicus, Cinnamomum camphora, Cirsium vulgare, Lantana camara, Sida rhombifoliaNumber of plots 21Total species 212Average number of species 37 ±7.7Conservation statusThis community is reserved Madman’s Creek Flora Reserve (15ha) and Sherwood Nature Reserve (40ha).TenureArea (ha)Crown Land 2Freehold 600Nature Reserve 40NSW State Forest 1 591NSW State Forest Flora Reserve 15TOTAL 2 248Threatened and Rare plants:Eucalyptus rummeryi, Plectranthus suaveolensRelationship to other communitiesRelated to CH_DOF05 (Foothills Grey Gum – Ironbark – Mahogany Dry Forest), CH_WSF17 (Foothills Turpentine -Grey Gum - Ironbark Moist Shrubby Forest) and CH_WSF11 (Foothills Spotted Gum – Mahogany - Grey Gum WetShrubby Forest). CH_DOF10 can be distinguished by the higher abundance (typically dominant or sub-dominant)of Spotted Gum (Corymbia variegata) and is distinguished from CH_WSF11 by a characteristic dry grassy/shrubbyunderstorey. The mapped occurrence of the map unit Ch_DOF10 has been shown to include elements of thedry sclerophyll community CH_DOF05 (Foothills Grey Gum-Ironbark - Mahogany Dry Forest) as the dominanceof Spotted Gum decreases. As CH_DOF10 grades into wet sclerophyll forest, elements of the communitiesCH_WSF11 (Foothills Spotted Gum - Mahogany - Grey Gum Wet Shrubby Forest), CH_WSF17 (Foothills Turpentine- Grey Gum - Ironbark Moist Shrubby Forest) and CH_WSF03 (Foothills and Escarpment Blue Gum - Tallowwood-Turpentine Wet Shrubby Forest) may be present.Vegetation Mapping of the Coffs Harbour Local Government Area Page 235
