| Short description | Eucalyptus melanophloia low woodland on skeletal soils on metamorphics hills |
| Structure code | Low Woodland |
| Description | Low woodland to low open woodland of Eucalyptus melanophloia (silver-leaved ironbark) or E. shirleyi +/- Corymbia peltata (rustyjacket) +/- C. dallachiana (Dallachy's gum) +/- E. crebra (narrow-leaved ironbark). There is usually no shrub-layer but scattered shrubs can occur and the ground is usually dense and grassy. Occurs on undulating rises and low metamorphic hills. Not a Wetland. (BVG1M: 17b). Vegetation communities in this regional ecosystem include: 9.11.1a: Low woodland to low open woodland of Eucalyptus melanophloia (silver-leaved ironbark) +/- E. persistens (box) +/- E. crebra (narrow-leaved ironbark) +/- Corymbia dallachiana (Dallachy's gum) +/- C. peltata (rustyjacket) +/- E. brownii (Reid River box) +/- Acacia julifera (catkin wattle). E. shirleyi (silver-leaved ironbark) may sometimes be dominant. The shrub layer is usually absent but scattered juvenile canopy species, Petalostigma spp., Denhamia cunninghamii and Hakea spp. may occur. The ground layer is dense grassy and includes Themeda triandra (kangaroo grass), Cymbopogon bombycinus (lemon-scented grass) and Heteropogon contortus (black speargrass). Occurs on skeletal soils of slopes and crests of undulating rises and low hills of folded metasediments and other metamorphic rocks. Not a Wetland. (BVG1M: 17b). 9.11.1b: Low open woodland to woodland of Eucalyptus melanophloia or E. shirleyi +/- Corymbia dallachiana (Dallachy's gum) +/- E. persistens (box) +/- C. peltata (rustyjacket) +/- E. crebra (narrow-leaved ironbark). There is usually no sub-canopy but scattered specimens of Petalostigma spp. Or Grevillea spp. Can occur. The shrub layer is generally absent but scattered shrubs can include Jacksonia ramosissima (angled broom bush), Acacia decora (showy wattle) and Dodonaea dodecandra (false hopbush). The mixed grassy ground layer can include Chrysopogon fallax (golden beard grass), Aristida spp., Digitaria spp., Triodia pungens (spinifex), Schizachyrium spp. (firegrass) and Cymbopogon bombycinus (lemon-scented grass). Occurs on skeletal soils of slopes and crests of undulating rises and low hills of folded metasediments and other metamorphic rocks. Not a Wetland. (BVG1M: 13c). |

| Fire management guidelines | INTERVAL: 10-50 years generally following periods of high rainfall and sufficient grass growth. INTERVAL_MIN: 10. INTERVAL_MAX: 50. STRATEGY: Maintain a landscape mosaic of burnt and unburnt in surrounding country to limit potentially invasive fires. ISSUES: Acacia species are vulnerable to frequent and high intensity fire. Burn surrounding country to mitigate intensity and extent of unplanned fire. Introduced invasive grasses are a threat to fire-sensitive communities. A. johannis are obligate seeders and require fire-free intervals of 5-8 years to maintain community. Contains the vulnerable Macropteranthes montana; no data available on vital attributes. |
| Comments | 9.11.1: Occurs from Greenvale to Charters Towers in the central and southern bioregion. 9.11.1a: Occurs from Greenvale to Lyndhurst in the central bioregion. 9.11.1b: Occurs from Greenvale to near Charters Towers in the central and southern bioregion. |
