CHaPTeR 2 Vegetation of the study area<br />
the study area to a small area in the south-west, this class is dominated by a range of<br />
species including Eucalyptus rossii, E. dalrypleana, E. blakelyi and E. goniocalyx.<br />
➜ Western Slopes dry sclerophyll forests (shrubby subformation): Found over a relatively<br />
wide area in the west of the study area, particularly around the Goulburn River and<br />
northern Wollemi areas. The indicative canopy species found in this class include<br />
Eucalyptus dealbata, E. sideroxylon, Callitris endlicheri and E. crebra.<br />
➜ Sydney Sand flats dry sclerophyll forests (shrubby subformation): Restricted to old<br />
alluvial and aeolian sand deposits on the Hawkesbury, Hunter and Goulburn river valleys;<br />
canopy dominants include Eucalyptus parramattensis, Angophora bakeri and E. sclerophylla,<br />
and the shrubby understorey often includes species of Banksia and Hakea.<br />
➜ northern gorge dry sclerophyll forests (shrub / grass subformation): Mainly restricted<br />
to the gorge country of the escarpment in the north of the study area; canopy dominants<br />
include Eucalyptus eugenioides and Corymbia intermedia on the steeper slopes and<br />
E. tereticornis and E. mollucana on lower slopes.<br />
➜ new england dry sclerophyll forests (shrub / grass subformation): Restricted to the New<br />
England Tableland and slopes in the north of the study area, this class is dominated by a<br />
range of species including Eucalyptus calliginosa, E. nobilis and E. pauciflora.<br />
➜ hunter–Macleay dry sclerophyll forests (shrub / grass subformation): This class is<br />
common across much of the study area and is represented by a number of different<br />
communities; common dominant canopy species include Corymbia maculata, Eucalyptus<br />
crebra, E. fibrosa, E. propinqua and E. punctata.<br />
➜ upper riverina dry sclerophyll forests (shrub / grass subformation): Restricted to a very<br />
small area in the western Blue Mountains in the far south-west of the study area, the canopy<br />
dominants include Eucalyptus albens, E. nortonii and E. polyanthemos subsp. polyanthemos.<br />
2.1.4 Grassy woodlands<br />
This formation is a prominent feature of the landscape over much of the drier (500 to 900 mm)<br />
parts of the study area on soils of medium to high fertility, and is characterised by an open to<br />
very open canopy dominated by eucalypts, particularly various box and red gum species. The<br />
ground layer is typically dense and composed of a diverse range of tussock grasses and other<br />
grasses and herbs. Much of the original extent of this formation has been cleared, primarily for<br />
agricultural purposes (Keith 2004).<br />
➜ tableland Clay grassy woodlands: Restricted within the study area to the higher altitude<br />
areas of the Barrington Tops, Northern Tablelands and Liverpool Range.<br />
➜ new england grassy woodlands: Restricted in the study area to the New England area<br />
in the north and scattered occurrences on higher sites in the Wollemi area to the south.<br />
➜ Western Slopes grassy woodlands: Common across much of the western parts of the<br />
study area including the Merriwa Plateau, Goulburn River and northern Wollemi areas.<br />
➜ Subalpine woodlands: Restricted to elevations between 1000 m and the physiological<br />
limit of tree growth around 1800 m, these woodlands occur within the study area only<br />
on the higher altitude areas of the Northern Tablelands and Barrington Tops to the north.<br />
The canopy is generally dominated by Eucalyptus pauciflora with E. stellulata and E.<br />
dalrympleana also common.<br />
➜ Coastal Valley grassy woodlands: Restricted to drier (700 to 1000 mm) near-coastal valleys<br />
this class is made up of a range of communities. Dominant canopy species commonly
