Regional ecosystem details for 12.11.13
| Regional ecosystem | 12.11.13 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Contains Palustrine |
| Biodiversity status | Of concern |
| Subregion | 10, 7, (5) |
| Estimated extent1 | Pre-clearing 4000 ha; Remnant 2021 2000 ha |
| Short description | Semi-evergreen vine thicket on metamorphics +/- interbedded volcanics, usually in northern half of bioregion |
| Structure code | Closed Forest |
| Description | Low microphyll vine forest +/- Araucaria cunninghamii and semi-evergreen vine thicket. Characteristic species include Brachychiton australis, B. rupestris, Archidendropsis thozetiana, Flindersia australis, F. collina, Psydrax odorata forma buxifolia, Alectryon diversifolius, Acacia fasciculifera, Turraea pubescens, Arytera microphylla, Atalaya salicifolia, Elattostachys xylocarpa, Grevillea helmsiae and Coatesia paniculata. Melaleuca bracteata is often present along watercourses. Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Contains Palustrine. (BVG1M: 7a). |
| Supplementary description | Bean et al. (1998), G13 (in part) |
| Protected areas | Bania NP, Nour Nour NP, Good Night Scrub NP, Oakview NP |
| Special values | 12.11.13: Potential habitat for NCA listed species: Backhousia oligantha, Hernandia bivalvis, Phebalium distans. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins. |
| Comments | 12.11.13: Occurs in north of bioregion and extends into adjacent parts of the brigalow belt. Remnants require intensive management because of weed invasion and fire damage on margins. |
