vulgare (Spear Thistle, 90%), Anagallis arvensis (Scarlet/Blue Pimpernel, 90%), Gomphocarpus
fruticosus (Narrow-leaved Cotton Bush, 50%), Plantago lanceolata (Lamb’s Tongues, 30%),
Senecio madagascariensis (Fireweed, 70%), Taraxacum officinale (Dandelion, 40%), Sonchus
oleraceus (Common Sowthistle, 90%), Opuntia stricta var. stricta (Common Prickly Pear,
90%), Bidens pilosa (Cobbler’s Pegs, 30%), Hypochaeris radicata (Catsear, 90%) and Arctotheca
calendula (Capeweed, 50%).
This community occurs within the study area on hills of the Central and Upper Hunter
Valley, mainly on coal measures at mid to low elevations.
MU 80 — White Box / Native Olive woodland of Upper Hunter and northern Wollemi National Park
Open forests to woodlands characterised by a canopy strongly dominated by Eucalyptus
albens and occasionally including other eucalypt species, such as E. moluccana and E. crebra.
A shrubby understorey is typically present and dominated by Notelaea microcarpa and
Dodonaea viscosa. The understorey typically consists of various forbs, including Cheilanthes
sieberi, Vittadinia sulcata, Calotis lappulacea, Einadia hastata and Rostellularia adscendens.
Various grass species may be common at some sites, including Aristida ramosa and Themeda
australis. Numerous, mainly herbaceous, naturalised species were commonly recorded in
this community, including Medicago minima (Woolly Burr Medic, 36%), Arenaria serpyllifolia
(Thyme-leaved Sandwort, 27%), Anagallis arvensis (Scarlet/Blue Pimpernel, 45%), Trifolium
campestre (Hop Clover, 27%), Trifolium arvense (Haresfoot Clover, 36%), Opuntia humifusa
(Creeping Pear, 27%), Opuntia stricta var. stricta (Common Prickly Pear, 55%), Bidens pilosa
(Cobbler’s Pegs, 55%), Paronychia brasiliana (Chilean Whitlow Wort, 27%) and Petrorhagia
nanteuilii (45%).
This community is distributed within the study area on a range of substrates, mainly
sandstones and conglomerates, on ranges of Central and Upper Hunter Valley and northern
Wollemi National Park at mid elevations.
MU 81 — Narrow-leaved Ironbark / Black Pine dry shrub / grass woodland
Open forests characterised by a canopy dominated by Eucalyptus crebra in association
with E. albens and Callitris endlicheri. The understorey is characteristically shrubby and
dominated by Notelaea microcarpa and Dodonaea viscosa. A diverse range of other shrubs is
also commonly present, including Olearia elliptica, Spartothamnella juncea, Grevillea montana
and Choretrum species A. The ground layer is typically grassy and dominated by Aristida
ramosa along with Cymbopogon refractus and generally also includes various ground ferns
and other herbaceous species, such as Cheilanthes sieberi, C. distans, Cyperus gracilis, Einadia
hastata and Brunoniella australis. Naturalised species recorded in more than 25% of sites
in this community were Senecio madagascariensis (Fireweed, 42%) and Opuntia stricta var.
stricta (Common Prickly Pear, 58%).
Within the study area, this community is distributed at mid to low elevations on ranges of
the Upper Hunter Valley, northern Wollemi NP and the Goulburn River area, mainly on
sandstones.
MU 82 — Narrow-leaved Ironbark / Coastal Myall / Native Olive woodland of Central Hunter
Open forests to woodlands characterised by Eucalyptus crebra in association with E.
punctata and Callitris endlicheri, with a small tree layer dominated by Acacia binervia and
90
