Description

Central Hunter Grey Box–Ironbark Woodland typically forms a woodland dominated by Narrow-leaved Ironbark (Eucalyptus crebra), Kurrajong (Brachychiton populneus subsp. populneus) and Grey Box (Eucalyptus moluccana). Other tree species such as Rough-barked Apple (Angophora floribunda) and Black Cypress Pine (Callitris endlicheri) may be present and occasionally dominate or co-dominate. A shrub layer is often present and common shrub species include Velvet Mock Olive (Notelaea microcarpa var. microcarpa), Coffee Bush (Breynia oblongifolia), Blackthorn (Bursaria spinosa subsp. spinosa), Cassinia quinquefaria and Sticky Hop-bush (Dodonaea viscosa). Subshrubs may also be common and include Narrawa Burr (Solanum cinereum), Phyllanthus virgatus and Small-leaf Bluebush (Maireana microphylla). Ground cover can be moderately dense to dense, and consist of numerous forbs and grass species as well as a small number of ferns, sedges and twiners. The more common species include Barbed Wire Grass (Cymbopogon refractus), Purple Wiregrass (Aristida ramosa), Kidney Weed (Dichondra repens), Poison Rock Fern (Cheilanthes sieberi subsp. sieberi), Bristly Cloak Fern (Cheilanthes distans), Tall Chloris (Chloris ventricosa), Slender Tick-trefoil (Desmodium varians), Yellow Burr-daisy (Calotis lappulacea), Many-flowered Mat-rush (Lomandra multiflora subsp. multiflora), Blue Trumpet (Brunoniella australis) and Glycine tabacina.

The Central Hunter Grey Box-Ironbark Woodland - Scientific Committee Determination states that the mapped area of the community is approximately 46,920 ha. However, this figure is the pre-European estimated area. The actual mapped area is 14,818 ha.

Habitat and ecology

  • Central Hunter Grey Box-Ironbark Woodland occurs in areas of relatively low rainfall and high temperatures. It is associated mostly with Permian lithology, and is situated on gently undulating hills, slopes and valleys, or occasionally on rocky knolls.
