Short description Corymbia spp. and Eucalyptus spp. woodland on sandstones of Ngarrabullan
Structure code Woodland
Description Mixed woodland to low woodland which can include a range of Corymbia spp. (bloodwoods) and Eucalyptus spp. (ironbarks). The shrub layer is sparse to mid-dense and can include Grevillea spp., Acacia spp. The ground layer is sparse to grassy. Occurs on the top, side slopes and talus footslopes of sandstone massifs. Not a Wetland. (BVG1M: 12b).

Vegetation communities in this regional ecosystem include:
9.10.7a: Woodland including combinations of Corymbia hylandii (Hyland's bloodwood), C. trachyphloia (brown bloodwood), C. leichhardtii (yellowjacket), C. tessellaris (Moreton Bay ash), Eucalyptus cloeziana (Gympie messmate) and E. cullenii (Cullen's ironbark. A shrub layer including Grevillea spp., Acacia spp., Coelospermum reticulatum (medicine bush) and Lamprolobium fruticosum is present. The ground layer includes tussock grasses and Xanthorrhoea sp. Occurs on the plateau. Not a Wetland. (BVG1M: 12b).
9.10.7b: Woodland of Corymbia stockeri +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- Eucalyptus crebra (narrow-leaved ironbark). The sparse mid layer includes shrubs of Alphitonia sp., Cupaniopsis anacardioides, Acacia spp., Coelospermum reticulatum (medicine bush), Denhamia cunninghamii (yellowberry bush) and Labichea brassii. The sparse ground layer includes Arundinella setosa, Triodia microstachya, Mnesithea rottboellioides (northern canegrass) and Lomandra multiflora subsp. multiflora. Occurs on plateau side slopes. Rocks are frequent. Not a Wetland. (BVG1M: 14d).
9.10.7c: Low woodland of Eucalyptus cullenii (Cullen's ironbark) +/- Corymbia stockeri subsp. peninsularis. A mid-dense shrub layer including Jacksonia thesioides, Melaleuca stenostachya, Petalostigma banksii (smooth-leaved quinine), Grevillea decora and Santalum lanceolatum (sandalwood) is present. The mid-dense ground layer includes Schizachyrium spp., Eriachne spp., Setaria surgens and Fimbristylis spp. with frequent bare patches. Occurs on talus footslopes. Not a Wetland. (BVG1M: 12b).
Special values 9.10.7: Habitat for the near threatened species Labichea brassii.
Fire management guidelines SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. Avoid burning August-October when south-easterly winds are typically strongest. INTENSITY: Low, with occasional moderate or high. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. ISSUES: These ecosystems contain shrubs that germinate after fire. Seedlings typically take a number of years to mature. Avoid repeated fires at short intervals and high intensity burns of broad areas. Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. Shrub species diversity will decline if areas are left long unburnt.
Comments 9.10.7: This Regional Ecosystem is restricted to Ngarrabullgan (Mt. Mulligan) in the central bioregion. 9.10.7a: Restricted to Ngarrabullgan (Mt. Mulligan) in the central bioregion. 9.10.7b: Restricted to Ngarrabullgan (Mt. Mulligan) in the central bioregion. 9.10.7c: Occurs on the eastern side of Ngarrabullgan (Mt. Mulligan) and the Featherbed Volcanics to the west.
