| Short description | Lophostemon spp. low closed forest on igneous rocks. Coastal hills |
| Structure code | Low Closed Forest |
| Description | Lophostemon spp. shrubby low closed forest. Associated shrubs include Acacia spp., Alphitonia excelsa and Xanthorrhoea johnsonii. Lophostemon confertus is the most common species in the top canopy layer. Eucalyptus exserta is consistently present, while Acacia simsii is often found. The mid-stratum is represented by Xanthorrhoea johnsonii, Acacia flavescens, Indigofera pratensis and Persoonia falcata. The ground layer includes Cheilanthes sieberi, Aristida superpendens, Themeda triandra, Lomandra longifolia and Cyanthillium cinereum. The only vines present are Eustrephus latifolius, Glycine clandestina and Muehlenbeckia rhyticarya. Occurs on Mesozoic to Proterozoic igneous rocks. Coastal ranges. Not a Wetland. (BVG1M: 28e). |

| Protected areas | Cape Upstart NP, Mount Abbot NP (S), Bowling Green Bay NP, Magnetic Island NP, Wongaloo CP, Bowling Green Bay CP |
| Special values | 11.12.14: Potential habitat for NCA listed species: Corchorus hygrophilus, Omphalea celata. |
| Fire management guidelines | SEASON: Mid- to late dry season. INTENSITY: Moderate to high. INTERVAL: 7-15 years. INTERVAL_MIN: 7. INTERVAL_MAX: 15. STRATEGY: Burn small areas in any year. Burn in association with surrounding vegetation. Protection from too frequent fire relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Fire exclusion not necessary. ISSUES: These ecosystems are often growing on and adjacent to rocky outcrops on mountains. Early dry season fires in the surrounding vegetation will usually not carry far into these outcrop ecosystems. It can take > 4 years for these shrubs to regrow to mature heights. Some lantana infestations occur on outcrop edges and fire can be of value in limiting establishment. Ensure mature shrubland structure persists for many years in between fire events. |
| Comments | 11.12.14: Found only on coastal hills above 350 m. The dominant tree present, Lophostemon confertus, occurs as a multi-stemmed tree. Surveyed examples are in good condition. |
