VOLUME 2: Vegetation Community Profiles - Coffs Harbour City ...

CH_DOF01This community is very widespread, occurring often on exposed to intermediate aspects on sedimentary andmetasedimentary coastal and hinterland hills. It also occurs on clay soils near creek banks and extending into theescarpment ranges and plateau rim on more exposed sites with less fertile soils. More commonly occurs below400m.Floristic summaryLayer Height (m)* Cover (%)* Dominant SpeciesTallest 5-30 18-65 Eucalyptus pilularis, Syncarpia glomulifera, Corymbiaintermedia, Eucalyptus microcorys, Eucalyptus resiniferasubsp. hemilampra, Angophora costata.Middle layer 1 5-20 20-55 Allocasuarina littoralis, Allocasuarina torulosa, Syncarpiaglomulifera.Middle layer 2 3-15 10-60 Dodonaea triquetra, Hovea acutifolia, Leucopogonlanceolatus, Notelaea longifolia, Persoonia stradbrokensis,Polyscias sambucifolia, Elaeocarpus reticulatus.Ground 0-0.5 60-90 Imperata cylindrica, Lomandra longifolia, Pteridiumesculentum, Calochlaena dubia, Blechnum cartilagineum,Dianella caerulea, Themeda australis, Hibbertia scandens,Cissus hypoglauca, Hibbertia aspera.* Data collated from 10 of 11 full floristic sitesStructural and floristic variationsSome occurrences of this community on metasedimentary geology around Toormina and Coffs Harbour maybe dominated or co-dominated by Scribbly Gum (Eucalyptus signata). Other species such as Sydney Blue Gum(Eucalyptus saligna) and Smooth-barked Apple (Angophora costata) occasionally occur in the community andmay be locally abundant. Variations in the understorey occur across the distribution of this community. Insome locations a heathy, dry and shrubby understorey is found. In other locations there has been significantdisturbance and the understorey is simple, grassy or contains exotics. This community is extensive throughout thestudy area and contains significant variation within the floristic profile.ExoticsAgeratina adenophora, Andropogon virginicus, Baccharis halimifolia, Cinnamomum camphora,Lantana camara, Paspalum urvillei, Schefflera actinophyllaSpecies richnessNumber of plots 11Total species 132Average number of species 33 ±6.2Conservation statusThis community is reserved in Bindarri National Park (49ha), Bongil Bongil National Park (50ha), Coffs CoastRegional Park (12ha), Garby Nature Reserve (28ha), Bruxner Park Flora Reserve (17ha), Sherwood Nature Reserve(109ha), Yuraygir National Park (632ha).Page 190Vegetation Mapping of the Coffs Harbour Local Government Area
