conglomerates and siltstones. This community may be of particular regional conservation<br />
significance due to the recorded presence of the rare orchid Acianthus amplexicaulis, which<br />
is not recorded in any other community in this study.<br />
MU 90 — Smooth-barked Apple open forest of coastal lowlands<br />
Open forests characterised by Angophora costata often co-dominant with Eucalyptus pilularis<br />
and less commonly with other eucalypts including E. piperita and E. globoidea. An open mid<br />
storey characterised by Allocasuarina torulosa and often including Clerodendrum tomentosum<br />
is typically present. The understorey is typically shrubby and commonly includes Polyscias<br />
sambucifolia, Breynia oblongifolia, Notelaea longifolia, Acacia longifolia and Dodonaea triquetra,<br />
along with scrambling climbers such as Eustrephus latifolius, Clematis aristata and Hibbertia<br />
dentata. The ground layer typically consists a mixture of grasses, predominately Oplismenus<br />
aemulus, Entolasia marginata, Imperata cylindrica, Poa affinis and Echinopogon ovatus; grasslike<br />
plants including Lomandra longifolia and Lepidosperma neesii; and ground ferns, mainly<br />
Adiantum aethiopicum and Pteridium esculentum. Various small herbs may also be commonly<br />
present, including Pratia purpurascens and Dichondra repens. Naturalised species commonly<br />
recorded in this community included Lantana camara (Lantana, 78%) and Chrysanthemoides<br />
monilifera subsp. rotundata (Bitou Bush, 56%).<br />
Within the study area, this community occurs on coastal lowlands of the Central Coast in<br />
the Macquarie / Tuggerah Lakes area.<br />
MU 91 — Large-fruited Grey Gum / Smooth-barked Apple / Blue-leaved Stringybark semi-mesic<br />
shrub / grass open forest on coastal ranges of the Sydney Basin<br />
Open forests characterised by Eucalyptus punctata, often in association with E. agglomerata,<br />
Angophora costata and Syncarpia glomulifera. An open mid storey is commonly present<br />
and characterised by Allocasuarina torulosa and may also include Acacia maidenii and<br />
A. implexa. The understorey is characteristically shrubby and may include a variety of<br />
smaller shrubs, such as Persoonia linearis, Platysace lanceolata, Podolobium ilicifolium, Cassinia<br />
cunninghamii and Polyscias sambucifolia, along with a diverse range of climbers, including<br />
Billardiera scandens, Hardenbergia violacea, Kennedia rubicunda and Eustrephus latifolius.<br />
The ground layer is characteristically dominated by grasses, including Entolasia stricta,<br />
Themeda australis, Microlaena stipoides and Panicum simile, and grass-like species, including<br />
Lepidosperma laterale, Dianella caerulea and Lomandra longifolia. Sparse ground ferns, mainly<br />
Cheilanthes sieberi, and herbs, including Pratia purpurascens, Goodenia heterophylla and<br />
Hybanthus monopetalus, are also commonly present. Naturalised species recorded in this<br />
community in more than 25% of sites were Senecio madagascariensis (Fireweed, 32%) and<br />
Hypochaeris radicata (Catsear, 32%).<br />
This community is distributed within the study area on the sandstone ranges of the Central<br />
Coast at mid to low elevations.<br />
MU 92 — Narrow-leaved Ironbark / Rough-barked Apple shrubby open forest<br />
Open forests with a canopy characterised by Eucalyptus crebra, often in association with<br />
Angophora floribunda, E. punctata and A. costata and occasionally with E. fibrosa. An open<br />
mid layer including Allocasuarina torulosa and Exocarpos cupressiformis may also be present.<br />
The understorey is typically shrubby and commonly includes Pultenaea scabra, Persoonia<br />
linearis, Exocarpos strictus, Acacia parvipinnula and Grevillea mucronulata, along with the<br />
