| Special values | 12.8.19: Habitat for threatened plant species including Arundinella grevillensis, Gonocarpus effusus, Pomaderris notata, Acacia saxicola, Allocasuarina emuina, A. thalassoscopica, Grevillea linsmithii, Westringia grandifolia, Leionema elatius subsp. beckleri, Coopernookia scabridiuscula, Dodonaea rupicola, Eucalyptus kabiana, Banksia conferta, Leptospermum luehmannii, L. oreophilum, Pultenaea whiteana, Westringia rupicola, Westringia sericea and near threatened species including Comesperma breviflorum, Eucalyptus codonocarpa, Westringia blakeana, Agiortia cicatricata, Zieria adenodonta. Habitat for many other species with restricted or disjunct distributions. |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 10-30 years. INTERVAL_MIN: 10. INTERVAL_MAX: 30. STRATEGY: Burn in association with surrounding vegetation. Protection relies on the broad-scale management of surrounding country. Fire exclusion and buffering from fire are not necessary. ISSUES: Some rare and threatened plants (e.g., near Crow's Nest and Biggenden) require long intervals between fires. There will be a number of obligate seeding species (e.g., Banksia conferta on Mt Barney, Mt Maroon, Glasshouse Mtns) in this community so variability in regime is required. Any planned burning should be conducted in association with plans for surrounding vegetation. Habitat for a number of species with restricted or disjunct distributions. |
| Comments | 12.8.19: Mapped area includes bare rock pavement. Higher altitude heaths exhibit a high level of species endemism. Frequent fire favours fire-tolerant species at the expense of fire-sensitive species. Often too small to map at 1:100 000 scale. |
