| Short description | Eucalyptus portuensis and E. drepanophylla +/- Corymbia intermedia +/- C. citriodora open woodland to open forest on dry uplands on alluvium |
| Structure code | Open Woodland |
| Description | Eucalyptus portuensis (white mahogany) and E. drepanophylla (ironbark) +/- Corymbia intermedia (pink bloodwood), +/- C. citriodora (lemon scented gum) open woodland to open forest. Uplands on alluvium, in the dry zone. Not a Wetland. (BVG1M: 9d). Vegetation communities in this regional ecosystem include: 7.3.48a: Eucalyptus portuensis, E. drepanophylla, Corymbia intermedia, C. citriodora, Lophostemon suaveolens, woodland and open forest with Melaleuca viridiflora, Acacia flavescens, and Allocasuarina littoralis. Areas of alluvium on uplands and highlands of the dry rainfall zone. Not a Wetland. (BVG1M: 9d). 7.3.48b: Corymbia citriodora, Eucalyptus portuensis, C. intermedia, Syncarpia glomulifera, woodland, low woodland and open forest with Callitris intratropica, Acacia calyculata and Xanthorrhoea johnsonii. Areas of alluvium uplands and highlands of the moist and dry rainfall zone. Not a Wetland. (BVG1M: 10b). |
| Supplementary description | Stanton and Stanton (2005), A16m, A16i; Tracey and Webb (1975), 16m, 16i |
| Protected areas | Kuranda West FR, Baldy Mountain FR, Daintree NP (CYPAL) |
| Fire management guidelines | SEASON: Cool, dry season (Apr-Sep). INTENSITY: Low to moderate. INTERVAL: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Mosaic burn < 30%. Begin burning early in the fire season, with progressive patch fires burnt through the year. Stop burning when the network of fires and other breaks is sufficient to impede fire spread later in the year. Storm-burning may be used to add further diversity to the fire mosaic. ISSUES: Ignition is most likely during hot, dry season (Oct - Jan). These fires are typically high intensity fires that can be difficult to control. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. |
| Comments | 7.3.48: In this RE the E. portuensis tends to be of lower stature and the ecosystem is more monospecific than 7.3.21 (and occurs in western rather than eastern areas). Scattered in western areas over most parts of the bioregion. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
