| Short description | Montane shrubland on igneous rocks |
| Structure code | Shrubland |
| Description | Montane shrub/heathland. Dominant species include Leptospermum amboinense, L. neglectum, Phebalium glandulosum, Acacia aulacocarpa, Leucopogon cuspidatus, Sannantha collina and Acacia humifusa. Sometimes emergent Eucalyptus exserta tree layer is present which may form a low woodland over localised areas. Occurs on mountain tops formed from Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 29b). Vegetation communities in this regional ecosystem include: 11.12.18a: Heathland or shrubland dominated by Leptospermum neglectum, Phebalium woombye, Grevillea banksii, Melaleuca hemisticta, sometimes with emergent Lophostemon confertus, Eucalyptus exserta and/or Corymbia intermedia. Occurs on pavements on exposed mountainous areas, formed from Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 29b). |

| 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 a mature shrubland structure persists for many years in between fire events. |
| Comments | 11.12.18a: Occurs near Mt Wheeler. |
