HClNC Vegetation Classification & mapping Project: Volume 1: Vegetation Classification Technical Report Leptocarpus tenax often strongly dominant. Other common graminoids include Empodisma minus, Schoenus brevifolius, Xyris gracilis and Burchardia umbellata. The main grass species is Entolasia stricta, and common forbs include Actinotus minor. The ground fern Gleichenia dicarpa may also be abundant at some sites. No naturalised species were recorded in this community at more than 25% of sites. This community occurs within the study area on poorly drained sites, mainly on sandstone ranges and plateaux of the Central Coast. MU 173 — Rock outcrops shrublands complex of the Lower North Coast A complex of shrublands dominated by a range of different shrub species, often including Allocasuarina rigida (commonly dominant and not recorded in this study from outside this community), Acacia obtusifolia, Leptospermum variabile, Zieria cytisoides, Persoonia linearis and Callistemon comboynensis. Other common, though less abundant, shrubs include Allocasuarina littoralis, Jacksonia scoparia and Leucopogon juniperinus. The ground layer includes various grasses such as Entolasia stricta, Microlaena stipoides and Poa sieberiana, with common graminoids including Lepidosperma laterale, Dianella caerulea, Lomandra glauca, L. longifolia and Patersonia glabrata. Commonly recorded forbs include Gonocarpus humilis and Xanthosia pilosa. No naturalised species were recorded in this community at more than 25% of sites. This community occurs within the study area on various substrates on rocky outcrops of the hinterland of the Lower North Coast. For mapping purposes MU 175 (see below) could also possibly be included with this complex. MU 174 — Broom Bush / Allocasuarina gymnanthera heath woodland Woodlands to heathlands characterised by Melaleuca uncinata and Allocasuarina gymnanthera, with other common shrubs including Leucopogon muticus, Harmogia densifolia, Dodonaea triangularis, Grevillea sericea, Melaleuca diosmatifolia, Acacia brownii, Persoonia linearis, Brachyloma daphnoides, Styphelia triflora and Calytrix tetragona. Eucalyptus fibrosa is also commonly present as an emergent tree. A mixed ground layer commonly consists of graminoids such as Dianella revoluta, Lomandra filiformis, L. multiflora and Lepidosperma laterale, grasses, predominately Entolasia stricta, forbs and ferns. The main ground fern is typically Cheilanthes sieberi, with common forbs including Drosera peltata and Goodenia rotundifolia. No naturalised species were recorded at more than 25% of sites in this community. Within the study area, this community occurs on exposed, sandstone sites in the northern Wollemi National Park, Goulburn River and Manobalai area at mid elevations. MU 175 — Shrublands of rocky areas in Barrington Tops area Shrublands characteristically strongly dominated by Leptospermum variabile, in association with Banksia integrifolia and occasionally with Micrantheum hexandrum (unique to this group within this study) as a co-dominant. Other common shrub species include Pomaderris argyrophylla, Hakea salicifolia, Hovea longifolia, Leucopogon lanceolatus and Monotoca scoparia. Various eucalypt species may be present at some sites as emergent trees, including Eucalyptus dalrympleana and E. pauciflora. The ground layer consists of a mix of grasses, graminoids, ferns and forbs, with common grasses including Entolasia stricta and Imperata cylindrica, 124
125 CHaPTeR 4 Results and common graminoids including Juncus alexandri, Bulbine bulbosa, Carex breviculmis, C. appressa, Cyperus sphaeroideus and Lepidosperma tortuosum. A diverse range of forbs is often present, including Epilobium gunnianum, Hydrocotyle peduncularis, Plectranthus graveolens, Acaena novae-zelandiae, Asperula scoparia, Geranium potentilloides and Wahlenbergia stricta. Common ground ferns include Cheilanthes sieberi, Blechnum minus, B. nudum and Pteridium esculentum. Naturalised species recorded at more than 25% of sites in this community include Holcus lanatus (Yorkshire Fog, 33%), Trifolium repens (White Clover, 33%), Prunella vulgaris (Self-heal, 33%), Sonchus asper subsp. glaucescens (Prickly Sowthistle, 33%) and Juncus articulatus (33%). Within the study area, this community is restricted to rocky outcrops in the Barrington Tops area of the Lower North Coast, at mid to high elevations. MU 176 — Tantoon / Lepyrodia leptocaulis drainage line shrubland of the western Blue Mountains Shrublands characterised by a shrub layer dominated by Leptospermum polygalifolium, often in association with Allocasuarina diminuta and Kunzea parvifolia. Other common shrubs include Melaleuca thymifolia, Grevillea sericea, Calytrix tetragona, Hibbertia riparia and Sannantha cunninghamii. Various trees may be present as emergents, including Eucalyptus punctata, E. blakelyi and Callitris endlicheri. The parasitic climbers Cassytha pubescens and C. glabella are also common in the shrub layer. The ground layer is characterised by Lepyrodia leptocaulis, with other common graminoids, including Schoenus apogon, Lomandra longifolia and Dianella longifolia. The main grass species include Arundinella nepalensis, Microlaena stipoides and Aristida jerichoensis, and the forbs include Goodenia paniculata which is commonly present. No naturalised species were recorded at more than 25% of sites in this community. Within the study area, MU 176 occurs on drainage lines on sandstone ranges of the western Blue Mountains at mid elevations. MU 177 — Melaleuca decora shrubland Shrublands characterised by Melaleuca decora, typically with Eucalyptus crebra as an emergent tree. Other commonly recorded shrubs include Notelaea microcarpa, Leptospermum parvifolium, Styphelia triflora, Spartothamnella juncea, Phyllanthus hirtellus, Leucopogon muticus and Acacia parvipinnula. The ground layer is typically dominated by graminoids, including Carex inversa, Schoenus apogon, Juncus homalocaulis and Gahnia aspera. A variety of forbs is also commonly present in the ground layer, including Veronica plebeia, Oxalis exilis, Hypericum gramineum and Glossogyne tannensis. Commonly recorded naturalised species include Senecio madagascariensis (Fireweed, 100%), Opuntia stricta var. stricta (Common Prickly Pear, 100%) and Hypochaeris radicata (Catsear, 100%).
