Microlaena stipoides, Themeda australis and Imperata cylindrica. Various small ferns and forbs
are also common in the ground layer, including Adiantum aethiopicum, Cheilanthes sieberi,
Pratia purpurascens and Dichondra repens. As with MU 58, a range of naturalised species
were commonly recorded in this community with the most frequent being Sida rhombifolia
(Paddy’s Lucerne, 28%), Gomphocarpus fruticosus (Narrow-leaved Cotton Bush, 28%),
Lantana camara (Lantana, 38%), Senecio madagascariensis (Fireweed, 48%), Sonchus oleraceus
(Common Sowthistle, 38%), Bidens pilosa (Cobbler’s Pegs, 41%) and Hypochaeris radicata
(Catsear, 62%).
Within the study area, this community occurs in the Central Hunter Valley, northern Yengo
and northern Wollemi areas at mid to low elevations on sandstones and siltstones.
MU 61 — White Box shrubby woodland with Semi-Evergreen Vine Thicket elements near
Glenbawn Dam
Sclerophyll woodlands, including elements of vine thicket, with a canopy dominated
by Eucalyptus albens and small trees, including Alectryon oleifolius, Geijera parviflora and
Clerodendrum tomentosum. This community is also characterised by a diverse range of
vines, including Marsdenia flavescens, Parsonsia eucalyptophylla, P. lanceolata, Cissus opaca
and Pandorea pandorana. The understorey is typically shrubby with characteristic species
such as Notelaea macrocarpa, Olearia elliptica, Rhagodia parabolica and Spartothamnella juncea.
The ground layer is sparsely grassy with the dominant grasses Austrostipa verticillata
and Austrodanthonia fulva, and typical ferns Pellaea falcata and Urtica incisa. Common
naturalised species recorded in this community were Conyza sumatrensis (Tall Fleabane,
67%), Cirsium vulgare (Spear Thistle, 47%), Asphodelus fistulosus (Onion Weed, 33%), Senecio
madagascariensis (Fireweed, 33%) and Opuntia stricta var. stricta (Common Prickly Pear,
100%).
This community is only recorded in the Glenbawn Dam area in the Upper Hunter Valley.
MU 62 — White Box / Blackthorn shrubby woodland of western Blue Mountains
Open forests to woodlands dominated by Eucalyptus albens with a small tree layer including
Brachychiton populneus and Acacia implexa. The understorey is characteristically shrubby and
may include Cassinia species D (recorded in only 0.2% of sites outside of this community),
Bursaria spinosa, Macrozamia communis and Melichrus urceolatus. The understorey commonly
consists of a range of forbs and graminoids with common species including Plantago
debilis, Dichondra repens, Stellaria pungens and Lomandra multiflora. Common naturalised
species recorded in this community included Trifolium arvense (Haresfoot Clover, 33%) and
Cynoglossum australe var. australe (33%).
Within the study area, this community occurs on sandstone ranges of the western Blue
Mountains and Wollemi NP at mid elevations. This community is of particular conservation
significance as it is the only community in this study in which the rare species Prostanthera
discolor has been recorded, although it does not appear to be common in this area.
