In disturbedexamples, the overstorey is often composed of scattered Coast Banksia (Banksia integrifolia subsp. integrifolia)and sometimes with plantings of native species such as Coast Tea-tree (Leptospermum laevigatum) and HorsetailShe-oak (Casuarina equisetifolia). Disturbed open areas often have a lower layer of weeds such as BitouBush (Chrysanthemoides rotundifolia subsp. monilifera) and grasses, while more protected and less disturbedsites contain littoral rainforest species such as Tuckeroo (Cupaniopsis anacardioides), Beach Apple (Acronychiaimperforata) and Beach Bird’s Eye (Alectryon coriaceus). Some of the least disturbed examples of this communityoccur in Bongil Bongil National Park south of Bundagen Headland.ExoticsAndropogon virginicus, Bidens pilosa, Chrysanthemoides monilifera subsp. rotundata,Cinnamomum camphora, Conyza bonariensis, Conyza parva, Gloriosa superba, Lantana camara, Oenothera affinis,Paspalum mandiocanum, Protasparagus aethiopicus, Senecio madagascariensis, Senna septemtrionalis, Solanumchenopodioides, Solanum nigrum, Sonchus oleraceusSpecies richnessNumber of plots 5Total native species 76Average number of species 24 ±5.8Conservation statusThis community is reserved in Bongil Bongil National Park (83ha), Coffs Coast Regional Park (53ha), Moonee BeachNature Reserve (37ha) and Yuraygir National Park (42ha)TenureArea (ha)Crown Land 147Freehold 56National Park 106Nature Reserve 37Regional Park 57TOTAL 404Threatened and Rare plants:Sophora tomentosaVegetation Mapping of the Coffs Harbour Local Government Area Page 247
