Regional ecosystem details for 9.8.7
| Regional ecosystem | 9.8.7 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Contains Palustrine |
| Biodiversity status | Of concern |
| Subregion | 5, (4), (3) |
| Estimated extent1 | Pre-clearing 86000 ha; Remnant 2021 86000 ha |
| Short description | Semi-evergreen vine thicket on cones, craters and rocky basalt flows with little soil development |
| Structure code | Low Closed Forest |
| Description | Semi-evergreen vine thicket with many codominant species, many vines and without clearly defined layers. Includes Gyrocarpus americanus (helicopter tree), Brachychiton australis (bottle tree), Pleiogynium timorense (Burdekin plum), Bridelia leichhardtii, Psydrax odorata, Cupaniopsis anacardioides, Diospyros humilis and Homalium brachybotrys. Can occur as a closed forest with Alstonia scholaris (milky pine), Terminalia sericocarpa (damsonwood), Nauclea orientalis (Leichhardt tree), Ficus racemosa (cluster fig) and F. virens (strangler fig) on creeks and around springs or as an open woodland of Corymbia tessellaris (Moreton Bay ash) and/or Eucalyptus tereticornis (bluegum) with an open mid layer of vine thicket species. Occurs on lava flows, cones and craters and rocky substrates with no soil development on Quaternary and Tertiary basalts. Contains Palustrine. (BVG1M: 7a). Vegetation communities in this regional ecosystem include: 9.8.7a: Softwood scrubs on rocky basalt substrates. Occurs on lava flows, cones and craters and rocky substrates with no soil development on Quaternary and Tertiary basalts. Not a Wetland. (BVG1M: 7a). 9.8.7b: Softwood scrubs on rocky basalt substrates with wetlands. Occurs on lava flows, cones and craters and rocky substrates with no soil development on Quaternary and Tertiary basalts. Palustrine. (BVG1M: 7a). |
| Protected areas | Great Basalt Wall NP, Kinrara NP, Undara Volcanic NP, Mount Rosey RR, Dalrymple NP, Girringun NP |
| Special values | 9.8.7: Habitat for near threatened and threatened flora species. Important seasonal wetland habitats associated with this ecosystem. Lava tunnels with endemic fauna and significant bat maternity sites. |
| 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 | 9.8.7: Occurs on basalt boulderfields throughout the bioregion. Prone to invasion by the weeds Cryptostegia grandiflora* (rubber vine) and Lantana camara. 9.8.7a: Occurs on basalt boulderfields throughout the bioregion. 9.8.7b: Occurs on basalt boulderfields throughout the bioregion. |
