MU 98 — Narrow-leaved Stringybark / Large-fruited Grey Gum shrubby open forest of northern
Wollemi National Park
Open forests with a canopy characterised by Eucalyptus sparsifolia and E. punctata, and
commonly including Angophora costata. The understorey is typically shrubby and consists
of a diverse range of species, including Persoonia linearis, Podolobium ilicifolium, Leucopogon
muticus, Hibbertia obtusifolia and Exocarpos strictus, as well as the climbers Hardenbergia
violacea and Billardiera scandens. The ground layer is generally sparse and consists of a
mixture of grasses, including Entolasia stricta; a range of grass-like plants, including
Lomandra confertifolia, Dianella caerulea and Lepidosperma laterale; and scattered forbs such
as Pomax umbellata. No naturalised species were recorded in more than 25% of sites in this
community.
Within the study area, this community occurs mainly on sandstones on ridges and upper
slopes of ranges in the northern Wollemi, Yengo NP and Central Hunter Valley areas. This
community may be of particular regional conservation significance as it includes the only
records in this study of the rare shrub Olearia cordata.
MU 99 — Sydney Peppermint / Large-fruited Grey Gum heathy open forest of north-west Wollemi
National Park
Open forests with an overstorey characterised by Eucalyptus piperita, often in association
with E. punctata and E. agglomerata. A shrubby mid storey, including Acacia obtusifolia
with Leptospermum trinervium, A. terminalis and Banksia serrata, is commonly present.
The understorey is often densely shrubby and consists of a diverse range of species,

Leucopogon lanceolatus and Monotoca scoparia, as well as climbers such as Smilax glyciphylla
and Hardenbergia violacea. The ground layer is characterised by a range of grass-like
species, including Lomandra obliqua, L. confertifolia, Dianella caerulea, Patersonia sericea and
Lepidosperma laterale; forbs, including Gonocarpus teucrioides, Gonocarpus tetragynus and
Hybanthus monopetalus; and scattered grasses, chiefly Entolasia stricta. No naturalised

The community is distributed within the study area on Triassic sandstone ranges of the
western Blue Mountains at mid to high elevations.
MU 100 — Sydney Peppermint semi-mesic open forest of northern Wollemi National Park
Open forests with an overstorey characteristically dominated by Eucalyptus piperita, often
in association with E. sparsifolia, and less commonly with E. cypellocarpa and E. punctata. The
understorey is typically shrubby and semi-mesic and consists of various taller shrubs, such
as Ceratopetalum gummiferum, Elaeocarpus reticulatus and Notelaea venosa; a diverse range of
smaller shrubs, including Persoonia linearis, Lomatia silaifolia, Polyscias sambucifolia, Acacia
saliciformis and Podolobium ilicifolium; as well as numerous climbers such as Hardenbergia
violacea, Pandorea pandorana and Billardiera scandens. The understorey is typically dominated
by various ferns, including Calochlaena dubia, Pteridium esculentum, Blechnum cartilagineum
and Lindsaea microphylla, and also includes various grasses and grass-like plants, such as
Poa affinis, Dianella caerula, Stylidium productum and Lomandra filiformis. Scattered forbs,
typically including Gonocarpus teucrioides, may also be present. No naturalised species
were recorded in this community in more than 25% of sites.
