Regional ecosystem details for 8.9.1
| Regional ecosystem | 8.9.1 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 5, 4 |
| Estimated extent1 | Pre-clearing 8000 ha; Remnant 2021 6000 ha |
| Short description | Eucalyptus latisinensis and/or Corymbia intermedia +/- Syncarpia glomulifera woodland on low rises in coastal plains |
| Structure code | Woodland |
| Description | Eucalyptus latisinensis and/or Corymbia intermedia +/- Syncarpia glomulifera woodland to open forest (9-24m tall). Occasionally Allocasuarina torulosa and/or A. littoralis may by dominant in the canopy, and E. latisinensis occurs as an emergent. Other associated canopy species may include E. crebra, C. trachyphloia and Lophostemon suaveolens. There is often a mid-dense to sparse (occasionally dense) secondary tree layer dominated by species such as Allocasuarina spp., Banksia integrifolia subsp. compar, Syncarpia glomulifera and Lophostemon suaveolens. A very sparse lower tree and/or shrub layer is usually present, with species including Allocasuarina spp., Grevillea banksii, Syncarpia glomulifera, Acacia crassa subsp. longicoma, Banksia robur and Acacia leiocalyx. The ground layer may be dominated by Xanthorrhoea latifolia subsp. latifolia, Themeda triandra, Entolasia stricta, Eremochloa bimaculata and Pteridium esculentum. Occurs on slopes and crests of gently undulating rises of coastal plains. Geology mapped as Qr, Qr,Tw, Qr>Ccs and Qr>PKg (Quaternary clay, silt, sand, gravel and soil; colluvial and residual deposits) and Ccs (Shoalwater Formation) Carboniferous quartzose sandstone and mudstone; local quartz-muscovite-biotite schist). Not a Wetland. (BVG1M: 9d). |

| Special values | 8.9.1: Habitat for species poorly known within the bioregion including Acacia leiocalyx subsp. leiocalyx and Gompholobium pinnatum. Northern limit of Eucalyptus latisinensis, Xanthorrhoea fulva, Hibbertia vestita, Hovea clavata and Patersonia sericea. |
| Fire management guidelines | SEASON: Late wet to early dry season, with occasional storm burns (Nov-Dec). Winter burns may be acceptable if conditions have not been appropriate for burning until winter. INTENSITY: Mainly low, but with some moderate and high. INTERVAL: 3-7 years. INTERVAL_MIN: 3. INTERVAL_MAX: 7. STRATEGY: Apply mosaic burns across the landscape at a range of intervals. At a fine scale attempt to create a spatial mosaic with multiple burn patches 20 ha or less; aim for a 30-50% burnt area. At the bioregion scale do not burn more than 20% within the same year. ISSUES: Lack of fire promotes overabundant pioneer rainforest species. Too frequent fire or inappropriately timed fire promotes weeds, including high-biomass grasses that lead to inappropriate fires. At least 7 years between burns is required to permit obligate seeding shrubs to reproduce. |
| Comments | 8.9.1: The only land zone 9 RE, this RE may appear similar to 8.3.8. however 8.3.8 occurs on alluvium whilst 8.9.1 occurs on low rises/undulating country. 8.3.8 also tends to be dominated (or codominated) by Eucalyptus latisinensis whilst 8.3.8 tends to be dominated by Syncarpia glomulifera and/or E. portuensis and/or Corymbia intermedia. Occurs in subregions 4 and 5, inland from the northern most part of Port Clinton south to Byfield. Currently reasonably good overall. |
