HClNC Vegetation Classification & mapping Project: Volume 1: Vegetation Classification Technical Report MU 63 — Spotted Gum / Grey Ironbark dry open forest of the Central Coast and Lower Hunter Open forests characterised by Eucalyptus paniculata in association with E. umbra. The canopy may also include various other eucalypts, in particular, E. tereticornis and E. crebra. The understorey is typically shrubby and often dominated by Macrozamia communis along with various other shrubs, including Notelaea longifolia, Dodonaea triquetra and Acrotriche divaricata, and climbers such as Pandorea pandorana and Eustrephus latifolius. The ground layer is characteristically grassy and commonly includes Entolasia stricta, Imperata cylindrica and Themeda australis, along with graminoids, such as Dianella caerulea and Lomandra longifolia, and sparse herbs such as Pratia purpurascens. This community appears to be highly susceptible to invasion by woody weeds, in particular, Chrysanthemoides monilifera subsp. monilifera (Boneseed) was recorded in all sites and Lantana camara (Lantana) was recorded in 85% of sites. Within the study area, this community occurs on coastal lowlands of the Central Coast, mainly on sandstones. MU 64 — Spotted Gum moist shrubby open forest Open forests characterised by a canopy dominated by Corymbia maculata in association with Eucalyptus umbra, E. punctata and E. paniculata. The understorey is generally shrubby and may include sparse tall shrubs, including Acacia implexa, A. longifolia and Exocarpos cupressiformis, along with a range of smaller shrubs, including Daviesia ulicifolia, Pultenaea villosa, Podolobium ilicifolium and Persoonia linearis. The understorey often includes a variety of climbing and scrambling species, including Pandorea pandorana, Billardiera scandens and Eustrephus latifolius. The ground layer is characteristically and often strongly dominated by a relatively diverse range of grass species, in particular, Themeda australis, Poa affinis, Entolasia stricta, Joycea pallida and Imperata cylindrica. A range of graminoid species are also characteristically present, including Lomandra confertifolia, L. longifolia, Dianella caerulea and Lepidosperma neesii, along with scattered forbs, such as Goodenia heterophylla and Pseudoraphis paradoxa. As with MU 63, this community appears to be particularly susceptible to invasion by Chrysanthemoides monilifera subsp. rotundata (Bitou Bush, 89%) and Lantana camara (Lantana, 48%). This community occurs within the study area on coastal lowlands of the Central Coast, mainly on sandstones. MU 64 is related to MU 63 but differs in the dominance of C. maculata which is uncommon in MU 63, and in having a more dominantly grassy ground layer. MU 65 — Spotted Gum / Broad-leaved Mahogany / Red Ironbark moist shrubby open forest Open forests with a canopy dominated by Corymbia maculata in association with Eucalyptus umbra and E. fibrosa and a small tree layer commonly including Allocasuarina torulosa. A diverse range of eucalypts may also be present in the canopy, including E. siderophloia and E. punctata. An open shrub layer may be present and include Daviesia ulicifolia, Bursaria spinosa and Leucopogon juniperinus, along with climbers, including Hardenbergia violacea, Eustrephus latifolius and Billardiera scandens. The ground layer is characteristically grassy and may include a diverse range of grasses, in particular, Entolasia stricta, Themeda australis, Imperata cylindrica, Microlaena stipoides and Panicum simile. Various herbs, such as Pratia purpurascens, Dianella caerulea and Vernonia cinerea along with ground ferns, predominately Cheilanthes sieberi, are also typically present. Commonly recorded weeds 84
85 CHaPTeR 4 Results in this community included Lantana camara (Lantana, 28%) and Senecio madagascariensis (Fireweed, 32%). This community occurs within the study area in the Lower Hunter Valley and coastal ranges of the Central Coast at lower elevations. MU 66 — Large-fruited Grey Gum / Rough-barked Apple open forest Open forests characterised by Eucalyptus punctata in association with Angophora floribunda. Various other eucalypts, including E. fibrosa and E. tereticornis, may also be present in the overstorey. The understorey is typically shrubby and may include taller shrubs and small trees, in particular, Leptospermum trinervium and Allocasuarina littoralis, along with a diverse range of smaller shrubs commonly including Persoonia linearis, Bursaria spinosa, Jacksonia scoparia and Acacia parvipinnula. The ground layer is characteristically grassy and often dominated by Themeda australis in association with a range of other grasses, commonly including Microlaena stipoides, Aristida vagans, Panicum simile and Imperata cylindrica. The understorey also typically includes ground ferns, mainly Cheilanthes sieberi, along with a variety of herbs, including Pomax umbellata and Pratia purpurascens, and the sedges Lepidosperma laterale and Gahnia aspera. The only naturalised species recorded in more than 25% of sites in this community was Hypochaeris radicata (Catsear, 28%). This community occurs within the study area on poorer fertility substrates on lower slopes and flats in the Lower Hunter Valley. MU 67 — Spotted Gum / Red Ironbark / Large-fruited Grey Gum shrub / grass open forest Open forests characterised by a canopy strongly dominated by Corymbia maculata and Eucalyptus fibrosa often in association with E. punctata. The shrubby understorey is characterised by a range of shrubs, including Daviesia ulicifolia, Persoonia linearis, Bursaria spinosa and Lissanthe strigosa. The ground layer is characteristically grassy and dominated by a range of species, including Themeda australis, Entolasia stricta, Aristida vagans and Panicum simile. Various graminoids are also typically present in the ground layer, in particular, Lepidosperma laterale, Dianella revoluta and Lomandra multiflora, along with ground ferns, typically Cheilanthes sieberi, and scattered herbs. Naturalised species recorded in more than 25% of sites in this community were Senecio madagascariensis (Fireweed, 33%) and Hypochaeris radicata (Catsear, 30%). Within the study area, this community occurs on a range of substrates in the Lower Hunter Valley at mid to lower elevations. This community has particular regional conservation significance as it relates to the Endangered Ecological Community ‘Lower Hunter Spotted Gum – Ironbark Forest in the Sydney Basin Bioregion’ (DECC 2009). MU 68 — Red Ironbark / paperbark shrubby open forest Open forests with a canopy strongly dominated by Eucalyptus fibrosa, often in association with Corymbia maculata, with a tall shrub layer dominated by Melaleuca nodosa and commonly including M. decora. The open shrub layer may include various shrubs, such as Bursaria spinosa, Pultenaea spinosa, Acacia parvipinnula and Macrozamia flexuosa; however, climbing species are not an abundant feature of the community. The ground layer is typically dominated by grasses, in particular, Entolasia stricta, Microlaena stipoides and Aristida vagans, and ground ferns, predominately Cheilanthes sieberi.
