| Regional ecosystem | 12.11.4 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Contains Palustrine |
| Biodiversity status | Of concern |
| Subregion | 10, (11.18) |
| Estimated extent1 | Pre-clearing 4000 ha; Remnant 2021 3000 ha |
| Short description | Semi-evergreen vine thicket on metamorphics +/- interbedded volcanics |
| Structure code | Closed Forest |
| Description | Low microphyll vine forest and semi-evergreen vine thicket. Characteristic species include Backhousia kingii, Pleiogynium timorense, Aidia racemosa, Archidendropsis thozetiana, Atalaya rigida, Barklya syringifolia, Bridelia leichhardtii, Elaeodendron melanocarpum, Backhousia subargentea, Flueggea leucopyrus, Homalium alnifolium and Terminalia porphyrocarpa. 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), H4, I3 |
| Protected areas | Dan Dan NP, Dawes NP, Curtis Island CP, Kroombit Tops NP, Curtis Island NP, Garden Island CP |
| Special values | 12.11.4: Habitat for threatened flora species including Rhodamnia angustifolia and Fontainea venosa. |
| 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 | 12.11.4: Occurs on north-west margins of bioregion in Wietalaba and Curtis Is area and extends into adjacent Brigalow Belt bioregion. Remnants prone to weed invasion and fire damage on margins. |
