| Regional ecosystem | 9.5.2 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 6, 4, (5), (2) |
| Estimated extent1 | Pre-clearing 7000 ha; Remnant 2021 6000 ha |
| Short description | Semi-evergreen vine thicket on red kandosols on Tertiary plateaus |
| Structure code | Closed Forest |
| Description | Semi-evergreen vine thicket often including Bridelia leichhardtii (small scrub ironbark), Lysiphyllum spp., Terminalia spp., Brachychiton australis (broad-leaved bottle-tree), Notelaea microcarpa (native olive), Pleiogynium timorense (Burdekin plum), Geijera salicifolia (narrow-leaved wilga) often with B. australis and Gyrocarpus americanus (helicopter tree) emergents. The sub-canopy to shrub layer is generally a continuum and usually includes canopy species, Everistia vacciniifolia, Ehretia membranifolia (peach bush), Alectryon connatus (grey bird's eye), Planchonella cotinifolia, Erythroxylum australe (cocaine tree), Diospyros humilis (Queensland ebony) and Carissa ovata (currantbush). The sparse ground cover can contain Ancistrachne uncinulata (hooky grass), Abutilon spp., and Croton spp. Vine species commonly found include Parsonsia spp., Cissus spp., Glossocarya hemiderma and Secamone elliptica (corky milk vine). Occurs on red kandosols, often overlying a lateritic surface, on Tertiary plateaus. Not a Wetland. (BVG1M: 7a). |
| Protected areas | Forty Mile Scrub NP |
| Special values | 9.5.2: Regional refugia for many plant and animal species. |
| Fire management guidelines | SEASON: Do not burn deliberately. INTENSITY: Do not burn deliberately. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Early dry season, low intensity burns in surrounding country to limit possibility of fire encroachment. ISSUES: Considered fire sensitive. Generally protected from fire by location in the landscape and few flammable grasses in understorey. Scorching of margins notable where there is disturbance, invasive high biomass grasses or lantana. Late dry season fires are particularly deleterious, leading to attrition of vine thicket. |
| Comments | 9.5.2: Includes a number of floristic communities. Scattered through the central and southern bioregion. Has been subject to clearing in some areas. |
