HClNC Vegetation Classification & mapping Project: Volume 1: Vegetation Classification Technical Report
Leptocarpus tenax often strongly dominant. Other common graminoids include Empodisma
minus, Schoenus brevifolius, Xyris gracilis and Burchardia umbellata. The main grass species
is Entolasia stricta, and common forbs include Actinotus minor. The ground fern Gleichenia
dicarpa may also be abundant at some sites. No naturalised species were recorded in this
community at more than 25% of sites.
This community occurs within the study area on poorly drained sites, mainly on sandstone
ranges and plateaux of the Central Coast.
MU 173 — Rock outcrops shrublands complex of the Lower North Coast
A complex of shrublands dominated by a range of different shrub species, often including
Allocasuarina rigida (commonly dominant and not recorded in this study from outside this
community), Acacia obtusifolia, Leptospermum variabile, Zieria cytisoides, Persoonia linearis
and Callistemon comboynensis. Other common, though less abundant, shrubs include
Allocasuarina littoralis, Jacksonia scoparia and Leucopogon juniperinus. The ground layer
includes various grasses such as Entolasia stricta, Microlaena stipoides and Poa sieberiana, with
common graminoids including Lepidosperma laterale, Dianella caerulea, Lomandra glauca, L.
longifolia and Patersonia glabrata. Commonly recorded forbs include Gonocarpus humilis and
Xanthosia pilosa. No naturalised species were recorded in this community at more than 25%
of sites.
This community occurs within the study area on various substrates on rocky outcrops of
the hinterland of the Lower North Coast. For mapping purposes MU 175 (see below) could
also possibly be included with this complex.
MU 174 — Broom Bush / Allocasuarina gymnanthera heath woodland
Woodlands to heathlands characterised by Melaleuca uncinata and Allocasuarina
gymnanthera, with other common shrubs including Leucopogon muticus, Harmogia densifolia,
Dodonaea triangularis, Grevillea sericea, Melaleuca diosmatifolia, Acacia brownii, Persoonia
linearis, Brachyloma daphnoides, Styphelia triflora and Calytrix tetragona. Eucalyptus fibrosa is
also commonly present as an emergent tree. A mixed ground layer commonly consists
of graminoids such as Dianella revoluta, Lomandra filiformis, L. multiflora and Lepidosperma
laterale, grasses, predominately Entolasia stricta, forbs and ferns. The main ground fern
is typically Cheilanthes sieberi, with common forbs including Drosera peltata and Goodenia
rotundifolia. No naturalised species were recorded at more than 25% of sites in this
community.
Within the study area, this community occurs on exposed, sandstone sites in the northern
Wollemi National Park, Goulburn River and Manobalai area at mid elevations.
MU 175 — Shrublands of rocky areas in Barrington Tops area
Shrublands characteristically strongly dominated by Leptospermum variabile, in association
with Banksia integrifolia and occasionally with Micrantheum hexandrum (unique to this group
within this study) as a co-dominant. Other common shrub species include Pomaderris
argyrophylla, Hakea salicifolia, Hovea longifolia, Leucopogon lanceolatus and Monotoca scoparia.
Various eucalypt species may be present at some sites as emergent trees, including Eucalyptus
dalrympleana and E. pauciflora. The ground layer consists of a mix of grasses, graminoids,
ferns and forbs, with common grasses including Entolasia stricta and Imperata cylindrica,
