| Short description | Acacia shirleyi low woodland on mesas and lateritised surfaces |
| Structure code | Low Woodland |
| Description | Low woodland to open forest of Acacia shirleyi (lancewood) or (occasionally) Eucalyptus exserta (Queensland peppermint). The shrub layer is usually absent but when present often includes Petalostigma banksii (smooth-leaved quinine). The sparse ground layer is often dominated by Triodia spp. (spinifex). Occurs on lateritised mesa slopes and remnant colluvium. Not a Wetland. (BVG1M: 24a). Vegetation communities in this regional ecosystem include: 9.7.2a: Woodland to low-woodland of Acacia shirleyi (lancewood) with only scattered Corymbia trachyphloia (brown bloodwood) +/- C. lamprophylla +/- Eucalyptus persistens (box) +/- Acacia leptostachya (slender wattle) +/- E. exserta (Queensland peppermint) +/- Corymbia spp. There may be a sub-canopy layer of A. shirleyi and a variety of other species. The shrub layer varies from none to mid-dense and includes Acacia spp., Persoonia falcata, Erythroxylum australe (cocaine tree) and/or Petalostigma banksii (smooth-leaved quinine). The ground layer is sparsely grassed and includes Aristida spp., Cleistochloa subjuncea and/or Triodia spp. (spinifex). Occurs on lateritised mesa slopes and tops, breakaways, scree slopes and remnant colluvium. Not a Wetland. (BVG1M: 24a). 9.7.2b: Woodland to low open woodland of Eucalyptus exserta (Queensland peppermint) +/- a mix of subdominant to codominant species including Acacia shirleyi (lancewood), Corymbia lamprophylla, C. peltata (rustyjacket) and Callitris intratropica (cypress pine). A moderate to dense shrub layer often includes Acacia leptostachya (slender wattle), A. shirleyi (lancewood) and Petalostigma banksii (smooth-leaved quinine) and the ground layer is dominated by Triodia spp. (spinifex). Occurs on rolling hills. Not a Wetland. (BVG1M: 13a). |
| Protected areas | Littleton NP, Girringun NP, Girringun CP, Bulleringa NP, Dalrymple NP, Littleton RR, Forty Mile Scrub NP |
| Special values | 9.7.2: Potential habitat for NCA listed species: Cerbera dumicola, Leptospermum pallidum. |
| 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 fire management of surrounding country so that wildfires will be very limited in extent and do not penetrate Lancewood forests. ISSUES: Although fire promotes the germination of Lancewood seedlings, trees are killed by all but the lowest intensity fires. Lancewood trees typically require approximately 20 years before seedlings mature. Often the lack of grass layer inhibits fire spread into these forests, and they will regenerate after occasional wildfires. Damaged by repeated fires < 20 years. Manage surrounding woodlands so that wildfires do not burn large areas of Lancewood forest in a single event. |
| Comments | 9.7.2: Occurs mainly around Greenvale in the central bioregion. 9.7.2a: Occurs mainly around Greenvale in the central bioregion. 9.7.2b: Occurs north-west of Greenvale in the central bioregion. |
