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
