Regional ecosystem details for 9.3.17
| Regional ecosystem | 9.3.17 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 5, 4, (10.3) |
| Estimated extent1 | Pre-clearing 9000 ha; Remnant 2021 9000 ha |
| Short description | Casuarina cunninghamiana and/or Eucalyptus camaldulensis or E. tereticornis fringing open forest on channels and levees on basalt flows |
| Structure code | Open Forest |
| Description | Open forest to open woodland of Casuarina cunninghamiana (river sheoak) and/or Eucalyptus tereticornis (bluegum) or E. camaldulensis (river red gum). Patches dominated by Melaleuca bracteata (black teatree) can also occur. The sub-canopy can be absent to mid-dense and include canopy species, M. fluviatilis (teatree) and M. leucadendra (weeping teatree). The shrub layer can be absent to open and include M. bracteata, juvenile canopy species and Ficus opposita (sandpaper fig). The ground layer is dense grassy and is dominated by Dichanthium spp. Occurs along banks and flats along creeks. Riverine. (BVG1M: 16a). |
| Protected areas | Porcupine Gorge NP |
| Special values | 9.3.17: Potential habitat for NCA listed species: Oenanthe javanica. |
| 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 | 9.3.17: Occurs north of the Great Basalt Wall in the south of the bioregion. Dichanthium aristatum* is sometimes common. |
