| Regional ecosystem | 12.12.11 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 10, 7, 5, (8), (6), (11.18) |
| Estimated extent1 | Pre-clearing 63000 ha; Remnant 2021 58000 ha |
| Short description | Eucalyptus portuensis or E. acmenoides, Corymbia trachyphloia subsp. trachyphloia woodland on Mesozoic to Proterozoic igneous rocks |
| Structure code | Woodland |
| Description | Eucalyptus portuensis or E. acmenoides, Corymbia trachyphloia subsp. trachyphloia woodland +/- E. crebra, C. intermedia, E. exserta and Angophora leiocarpa. Whipstick Lophostemon confertus often present in understorey and in gullies. Occurs on hillsides on Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 9h). |
| Supplementary description | Ryan, T.S. (ed.) (2012); Bean et al. (1998), H24, J12 |
| Protected areas | Eurimbula NP, Mount Walsh NP, Kroombit Tops NP, Castle Tower NP, Wongi NP, Bulburin NP, Beninbi NP, Deepwater NP, Eurimbula RR |
| Special values | 12.12.11: Potential habitat for NCA listed species: Acacia sp. (Castletower N.Gibson TOI345), Cassinia collina, Commersonia leiperi, Daviesia discolor, Eucalyptus decolor, Grevillea venusta, Habenaria xanthantha, Macrozamia cardiacensis and Melaleuca formosa. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-15 years. INTERVAL_MIN: 4. INTERVAL_MAX: 15. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. Control of weeds with fire might be required. Presence of blady grass Imperata cylindrica could be a problem and not indicative of a healthy system. |
| Comments | 12.12.11: Mostly in the northern half of bioregion. |
