| Regional ecosystem | 8.3.8 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 5, 4, (11.14) |
| Estimated extent1 | Pre-clearing 10000 ha; Remnant 2021 6000 ha |
| Short description | Syncarpia glomulifera and/or Eucalyptus portuensis and/or Corymbia intermedia open forest on sandy terrace flats and granite outwash |
| Structure code | Open Forest |
| Description | Syncarpia glomulifera and/or Eucalyptus portuensis and/or Corymbia intermedia open forest to woodland (15-30m tall). Associated species in the canopy may include Lophostemon suaveolens, C. trachyphloia, E. latisinensis and E. platyphylla. There is often a secondary tree layer dominated by species such as Allocasuarina torulosa, A. littoralis, Melaleuca viridiflora var. viridiflora, Banksia integrifolia subsp. compar and Lophostemon suaveolens. There is usually a shrub layer, with typical species including Grevillea banksii, Allocasuarina spp., Melaleuca viridiflora var. viridiflora, Acacia leptocarpa, Planchonia careya, A. flavescens and A. leiocalyx. The ground layer is commonly dominated by Themeda triandra, Xanthorrhoea latifolia subsp. latifolia, Heteropogon triticeus, Eremochloa bimaculata, Arundinella nepalensis and Imperata cylindrica. Plains, slopes, terrace flats, stream channels and footslopes on level plains to rolling hills of foothills. Geology mapped as Qa, Qr,Tw, Qr>PKg, Qr and Qr>Ccs (Quaternary clay, silt, sand, gravel and soil; floodplain alluvium, colluvial and residual deposits). Riverine. (BVG1M: 9d). |

| Protected areas | Byfield NP |
| Special values | 8.3.8: Habitat for the NCA listed species Grevillea venusta. Habitat for species poorly known from the Central Queensland Coast such as Persoonia amaliae, Hibbertia velutina, Gompholobium pinnatum, and for Bowenia serrulata which is highly restricted in distribution (Byfield area). Northern limit of the range of Corymbia gummifera, Daviesia umbellulata, Grevillea venusta (mostly restricted to Shoalwater area), Persoonia virgata, Pomaderris ferruginea, Hibbertia vestita, Macrozamia miquelii and Hovea clavata. |
| Fire management guidelines | SEASON: Late autumn to early winter. INTENSITY: Low to moderate. INTERVAL: Minimum of 4-5 years between fires. INTERVAL_MIN: 4. INTERVAL_MAX: 50. ISSUES: Consider pollination and fruiting events of Bowenia serrulata and avoid burning during these periods where practical. Mosaic burning will be important to avoid significant impacts of fire on the long term persistence of Bowenia and fauna which utilise this habitat. |
| Comments | 8.3.8: Distinguished from all other land zone 3 regional ecosystems by the dominance of Syncarpia glomulifera or Eucalyptus portuensis or Corymbia intermedia (usually with S. glomulifera and/or E. portuensis). May look similar to 8.9.1 but 8.9.1 occurs on low rises (land zone 9). Occurs in subregions 4 and 5 in an area west of Cape Manifold to Corio Bay. Some areas have been invaded by feral pine trees (self propagating). Some areas of freehold land are being cleared for pine plantations. Plant harvesting is a potential threat. |
