HClNC Vegetation Classification & mapping Project: Volume 1: Vegetation Classification Technical Report Dry rainforests MU 15 — Brown Myrtle / Lilly Pilly dry rainforest Low open forests to low closed forests with a canopy strongly dominated by Choricarpia leptopetala, with other common canopy species including Acmena smithii, Acacia maidenii, Stenocarpus salignus, Notelaea longifolia, Clerodendrum tomentosum, Diospyros australis, Pittosporum undulatum and Drypetes deplanchei. Eucalyptus microcorys is also commonly present as a canopy emergent. The mid storey consists of various shrubs, including Pittosporum revolutum and Breynia oblongifolia. Various climbers are also typically present in the mid and overstorey, including Smilax australis, Parsonsia straminea, Morinda jasminoides, Geitonoplesium cymosum, Embelia australiana, Dioscorea transversa and Cayratia clematidea. The ground layer is typically sparse, with few species being frequently present, although various graminoids (particularly Gymnostachys anceps), forbs, ferns and grasses may occasionally be present. The only naturalised species recorded in more than 25% of sites in this community was Lantana camara (Lantana, 38%). This community is distributed within the study area on coastal ranges of the Lower North Coast and Central Coast on sandstone and volcanic breccia substrates. MU 16 — Grey Myrtle dry rainforest of sheltered sandstone gullies in northern Wollemi National Park Low open forests to low closed forests characterised by a canopy strongly dominated by Backhousia myrtifolia, often in association with Acacia prominens and with Syncarpia glomulifera and Angophora floribunda. The understorey typically consists of a range of shrubs, including Breynia oblongifolia, Pittosporum revolutum, Persoonia linearis, Maytenus silvestris, Bursaria spinosa, Polyscias sambucifolia and Solanum stelligerum. A relatively diverse range of climbers is also typically present in the overstorey and shrub layer, including Pandorea pandorana, Eustrephus latifolius, Morinda jasminoides, Clematis aristata, Cissus hypoglauca, Smilax australis, Billardiera scandens and Sarcopetalum harveyanum. The ground layer is typically ferny, with the main fern species including Doodia aspera, Adiantum aethiopicum, A. hispidulum and Asplenium flabellifolium. Also common in the ground layer are various grasses, including Poa affinis and Oplismenus imbecillis; graminoids, such as Lepidosperma laterale and Dianella caerulea; and forbs, including Pratia purpurascens and Plectranthus parviflorus. No naturalised species were recorded in more than 25% of sites in this community. Within the study area, this community occurs in sandstone gullies on the Central Coast hinterland and western Blue Mountains at mid to low elevations. MU 15 may have particular regional conservation significance as the only records in this study of the rare shrub Acacia matthewii are from sites in this community. MU 17 — Grey Myrtle / Large-fruited Grey Gum gully rainforest of northern Wollemi National Park and Upper Hunter Valley Low open forests to low closed forests characterised by a canopy strongly dominated by Backhousia myrtifolia, often in association with Stenocarpus salignus, and with Eucalyptus punctata and Angophora floribunda commonly present as canopy emergents. Common understorey shrubs include Bursaria spinosa and Persoonia linearis. The ground layer is generally sparse and consists of a mix of grasses, graminoids and ferns. The main grass species is Poa affinis, and common graminoids include Gahnia aspera and Lepidosperma 68
69 CHaPTeR 4 Results laterale, while ground ferns include Asplenium flabellifolium and Cheilanthes sieberi. The only naturalised species recorded at more than 25% of sites in this community is Opuntia stricta var. stricta (Common Prickly Pear, 30%). This community is distributed within the study area in sheltered gullies on sandstone ranges of northern Wollemi and Upper Hunter Valley at mid to low elevations. MU 18 — Whalebone Tree / Red Kamala dry subtropical rainforest of the Lower Hunter River Open forests to closed forests with a relatively diverse canopy characterised by Streblus brunonianus and Mallotus philippensis. Other common canopy species include Alectryon subcinereus, Olea paniculata, Elaeocarpus obovatus, Dysoxylum fraserianum, Baloghia inophylla and Dendrocnide excelsa. The understorey consists of various small trees and shrubs commonly including Capparis arborea, Notelaea longifolia, Diospyros australis, Claoxylon australe, Clerodendrum tomentosum, Scolopia braunii and Breynia oblongifolia. A diverse range of climbers are also common in the mid and overstorey, including Cissus antarctica, Legnephora moorei, Tetrastigma nitens, Cayratia clematidea, Maclura cochinchinensis, Pandorea pandorana, Dioscorea transversa, Parsonsia straminea, P. velutina and Geitonoplesium cymosum. The ground layer consists of a mix of ferns, grasses, forbs and graminoids. Common grasses include Oplismenus aemulus and O. imbecillis, with common ferns being Adiantum formosum and Pellaea paradoxa. The main graminoid species is Gymnostachys anceps and common forbs include Pseuderanthemum variabile. The only naturalised species recorded at more than 25% of sites in this community is Lantana camara (Lantana, 54%). This community occurs within the study area in sheltered sites on ranges of the Hunter Valley and Lower North Coast escarpment at mid to low elevations. MU 19 — Shatterwood dry rainforest Open forests to closed forests characterised by a canopy dominated by Backhousia sciadophora and commonly including Stenocarpus salignus and Brachychiton populneus. The understorey typically consists of various small trees and shrubs including Pittosporum undulatum, Clerodendrum tomentosum, Diospyros australis, Olearia viscidula, Notelaea longifolia, Myoporum montanum, Jasminum volubile, Solanum stelligerum, Capparis arborea and Maytenus silvestris. Numerous climbers, including Cissus opaca, Parsonsia lanceolata, P. straminea, Geitonoplesium cymosum, Pandorea pandorana, Cayratia clematidea and Morinda canthoides, are also common in the mid and upper storey, along with epiphytes, such as Dendrobium schoeninum, D. fairfaxii and D. gracilicaule. The ground layer is generally relatively sparse and includes a mix of forms with the common graminoids Lepidosperma laterale and Gahnia aspera, and the common forbs Plectranthus graveolens, Pseuderanthemum variabile and Commelina cyanea. The main grass species is Microlaena stipoides and the main ground fern is Pellaea paradoxa. Naturalised species commonly recorded at sites in this community include Lantana camara (Lantana, 33%), Phytolacca octandra (Inkweed, 33%) and Solanum nigrum (Black-berry Nightshade, 67%). Within the study area, this community occurs on ranges and foothills of the northern escarpment, Lower North Coast, at mid elevations. MU 20 — Rusty Fig / Alectryon subcinereu / Native Olive / dry rainforest of the Central Hunter Valley Open forests to closed forests characterised by a canopy dominated by Ficus rubiginosa in association with Alectryon subcinereus and commonly including Melia azedarach.
