Regional ecosystem details for 9.3.15
| Regional ecosystem | 9.3.15 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 6, 4, 3, (2), (5), (7.4), (7.6), (7.5) |
| Estimated extent1 | Pre-clearing 21000 ha; Remnant 2021 20000 ha |
| Short description | Eucalyptus tereticornis +/- Casuarina cunninghamiana +/- Melaleuca spp. fringing woodland on channels and levees |
| Structure code | Woodland |
| Description | Fringing woodland to open forest containing any combination of Casuarina cunninghamiana, Eucalyptus tereticornis and E. platyphylla +/- Lophostemon suaveolens +/- Nauclea orientalis +/- Corymbia tessellaris +/- C. clarksoniana. There is often a low sub-canopy layer which can include canopy species and Ficus spp. The open shrub layer contains juvenile canopy species and can include mesic species such as Euroschinus falcatus, Acacia mangium and Syzygium sp. The ground layer is medium to dense grassy and contains Imperata cylindrica, Crotalaria sp., Heteropogon contortus, Cyperus spp. and Paspalum spp. Occurs on stream banks and channels in areas of higher rainfall in the central east of the bioregion (subregion 6). Riverine. (BVG1M: 16a). |
| Protected areas | Girringun NP, Girringun CP, Girringun RR, Evelyn Creek CP |
| Special values | 9.3.15: Significant habitat as drought refuge, wildlife corridors and for arboreal animals. |
| Fire management guidelines | SEASON: Late wet/early dry season (March to June). INTENSITY: Low. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Allowing fires to trickle into fringing community will reduce fuel load, loss of hollow trees and potential for wildfire. ISSUES: Contain fire sensitive species such as river she-oak Casuarina glauca, Melaleuca leucadendra and M. argentea as well as habitat trees. Frequent and high intensity fires remove or inhibit structural complexity of ground, mid and upper strata. Increases risk of weeds and erosion. |
| Comments | 9.3.15: In areas close to the Wet Tropics bioregion mesic species such as Tristaniopsis spp. and Syzygium spp. may occur. In areas of higher rainfall in the central east of the bioregion. Subject to clearing. Also very prone to weed infestation, including Lantana camara, Megathyrsus maximus, Melinis repens, Passiflora sp. and Mesosphaerum suaveolens. |
