HClNC Vegetation Classification & mapping Project: Volume 1: Vegetation Classification Technical Report
MU 128 — Mugga Ironbark / Black Pine shrub / grass open forest of far west Upper Hunter
Open forests characterised by an overstorey strongly dominated by Eucalyptus sideroxylon,
usually with Callitris endlicheri as a co-dominant. A mid storey characterised by Allocasuarina
gymnanthera is also commonly present. The understorey is shrubby and typically includes
Brachyloma daphnoides, Leucopogon attenuatus, Cassinia arcuata, Grevillea sericea, Melichrus
urceolatus, Macrozamia secunda, Xanthorrhoea australis and Platysace ericoides. The ground
layer commonly consists of a mix of grasses, including Aristida jerichoensis and Dichelachne
micrantha; forbs, including Pomax umbellata, Wahlenbergia gracilis and Goodenia glabra;
various graminoids, including Lepidosperma laterale and Gahnia aspera; and the ground fern
Cheilanthes sieberi. No naturalised species were recorded at more than 25% of sites in this
community.
This community occurs within the study area on sandstone ranges of the Goulburn River
and Turrell State Forest areas.
MU 129 — Tumbledown Red Gum / Spinifex grass heathy low open woodland of the western Blue
Mountains
Low open woodlands characterised by Eucalyptus dealbata, sometimes with E. goniocalyx,
E. laevopinea and E. cannonii present in the canopy. An open mid storey of Allocasuarina
gymnanthera is commonly also present. The understorey is typically densely shrubby and
commonly includes Styphelia triflora, Sannantha cunninghamii, Persoonia linearis, Xanthorrhoea
johnsonii, Acacia obtusata, Leucopogon attenuatus and Acacia leucolobia, along with scrambling
climbers such as Billardiera scandens and Hardenbergia violacea, and the parasitic climber
Cassytha pubescens. The ground layer is predominately grassy and characteristically
dominated by Triodia scariosa, with other common grasses including Joycea pallida, Aristida
jerichoensis and Entolasia stricta. The ground layer also commonly includes grass-like
species, such as Lepidosperma laterale and Lomandra filiformis, as well as various forbs such as
Gonocarpus elatus, Actinotus helianthi and Pomax umbellate, and the ground fern Cheilanthes
sieberi. No naturalised species were recorded at more than 25% of sites in this community.
Within the study area, this community is found on trachyte outcrops on ranges of the
western Blue Mountains.
MU 130 — Whipstick Mallee Ash / Yertchuk heathy mallee woodland of central Wollemi National
Park
Open forests to woodlands characterised by a canopy strongly dominated by Eucalyptus
multicaulis and E. consideniana. The understorey is typically densely shrubby, with
common shrub species including Isopogon anemonifolius, Platysace lanceolata, Leptospermum
trinervium, Bossiaea heterophylla, Persoonia levis, Mirbelia rubiifolia, Lomatia silaifolia, Monotoca
scoparia, Hakea dactyloides and Xanthorrhoea media. The ground layer consists predominately
of graminoids including Patersonia glabrata, P. sericea, Caustis flexuosa, Lomandra obliqua,
L. glauca and Stylidium productum. The main grass species is Entolasia stricta, and various
forbs, including Pomax umbellata and Actinotus minor, may also be present in the ground
layer. No naturalised species were recorded at more than 25% of sites in this community.
This community occurs within the study area on ridgetops of ranges of the western Blue
Mountains at mid to high elevations and mainly on Narrabeen sandstones.
