| Short description | Welchiodendron longivalve, Acacia brassii low woodland on igneous hills |
| Structure code | Low Woodland |
| Description | Welchiodendron longivalve (yellow box penda) low woodland commonly with Acacia brassii. May occur as a shrubland of Melaleuca viridiflora (broad-leaved teatree) and W. longivalve on some windswept headlands. Occurs on undulating igneous rises to steep hills. Not a Wetland. (BVG1M: 28c). Vegetation communities in this regional ecosystem include: 3.12.43a: Welchiodendron longivalve (yellow box penda) low woodland to woodland commonly with Acacia brassii. Eucalyptus cullenii (Cullen's ironbark) and E. platyphylla (poplar gum) can occur as co-dominants. Canopy species and occasionally Bursaria incana and Livistona muelleri (cabbage palm) appear in a very sparse subcanopy. Juvenile W. longivalve and Cochlospermum gillivraei (kapok) are common in the very sparse to sparse shrublayer along with numerous heath and rainforest species. The sparse to mid-dense grassy groundlayer can include Heteropogon triticeus (giant spear grass), Schizachyrium spp. (fire grass), Lomandra spp. And Schoenus sparteus. Occurs on undulating igneous rises to steep hills. Not a Wetland. (BVG1M: 28c). 3.12.43b: Melaleuca viridiflora (broad-leaved teatree) and Welchiodendron longivalve (yellow box-penda) shrubland to dwarf open shrubland commonly with Asteromyrtus brassii and Lithomyrtus retusa. Other species that can occur include Psydrax reticulata, Alyxia spicata (chain fruit), Acacia brassii, Jacksonia thesioides (broombush), Corymbia tessellaris (Moreton Bay ash), Syzygium suborbiculare (white apple), Acacia leptocarpa, A. simsii, Asteromyrtus symphyocarpa, Parinari nonda (nonda plum), Cochlospermum gillivraei (kapok), Exocarpos latifolius or M. stenostachya. The groundcover is principally stunted shrubs but scattered Dianella spp., Themeda triandra (kangaroo grass), Cassytha filiformis (dodder), Aristida spp., Schoenus spp., Thaumastochloa spp. Or Alloteropsis semialata (cockatoo grass) can occur. Restricted to igneous headlands on infertile skeletal soils. Not a Wetland. (BVG1M: 29a). |

| Fire management guidelines | SEASON: Burn any time after the wet season when sufficiently dry to carry fire, with occasional storm or late dry season burns (Oct-Jan). a,b: Storm time. INTENSITY: Low to moderate, with some high intensity burns late in the dry season. a,b: Moderate to high. INTERVAL: 1-5 years. a,b: 15-20 years. INTERVAL_MIN: 1. INTERVAL_MAX: 20. STRATEGY: Apply a mosaic of burns to break up the continuity of fuels across the landscape and limit the extent of late season wildfire. Begin burning early in the fire season, followed by progressive patch fires burnt through the year. Burn up to 30% in any year. a,b: Generally exclude fire, burning less than 10% in any year. ISSUES: High intensity fires are required to prevent vegetation thickening. High intensity fires will be difficult to achieve because of low fuel availability and accumulation rates and typically moister conditions. a,b: Fires should be lit when the conditions are high enough to ensure germination of hard-seeded plants, but when fire spread will be restricted. A combination of early to mid-dry season fires and storm-burns will maintain a mosaic of fire ages, but the aim should be to generally exclude fire. |
