| Short description | Eucalyptus camaldulensis woodland on levees and floodplains |
| Structure code | Woodland |
| Description | [RE not in use]²: This regional ecosystem has been amalgamated into 2.3.26. Eucalyptus camaldulensis fringing woodland. Eucalyptus microtheca may be present as a lower tree on fine-textured deposits, and Pandanus spp. +/- Melaleuca spp. On coarser soils. Terminalia spp. And/or Lophostemon grandiflorus may occur on upper tributaries. Occurs on levees and some floodplains of larger watercourses; alluvial soils and calcareous cracking clays. Riverine. (BVG1M: 16a). Vegetation communities in this regional ecosystem include: 2.3.25a: [RE not in use]²: This vegetation community is now mapped as 2.3.26b. Eucalyptus camaldulensis woodland, commonly with Melaleuca fluviatilis, M. argentea and M. leucadendra. Pandanus spp., Syzygium eucalyptoides and Lysiphyllum cunninghamii occasionally occur in the canopy. A shrub layer commonly occurs, including Acacia torulosa and Ficus opposita. The sparse ground layer commonly includes Aristida spp., Heteropogon contortus and areas of bare sand. Occurs on fringes and in channels of major watercourses. Riverine. (BVG1M: 16a). 2.3.25d: [RE not in use]²: This vegetation community is now mapped as 2.3.26c. Eucalyptus camaldulensis low woodland, commonly with Melaleuca viridiflora. M. citrolens, M. nervosa, M. fluviatilis and Pandanus sp. may occur in the canopy. The ground layer is sparse tussock grasses. Small areas of bare sand may occur. Occurs on fringes and in channels of minor watercourses in broad, Tertiary sand sheets. Riverine. (BVG1M: 16a). |
| Supplementary description | Neldner (1991), 1; Perry et al. (1964), Georgina, Cloncurry, Gregory, Donaldson, Torwood, Ortona |
| Special values | 2.3.25: Provincial refuge for some flora and fauna. Includes pools with permanent water in subregions 6 and 9, significant for aquatic species. 2.3.25a: Provincial refuge for flora and fauna. |
| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Restrict extent and intensity of fires. High intensity and extensive fires will degrade vegetation structure and destroy animal habitats. Burn only under mild conditions. |
| Comments | 2.3.25: Diverse ecosystem requiring further classification and verification of condition. High total grazing pressure is leading to soil erosion, scalding and habitat loss. *Cryptostegia grandiflora (rubber vine) is a major threat in some areas. 2.3.25a: Subject to degradation from high total grazing pressure. May be invaded by *Cryptostegia grandiflora (rubber vine). |
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.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
