| Structure code | Woodland |
| Description | Billabongs (preferential channel waterholes). A variable wooded fringe commonly occurs, including Eucalyptus spp., Corymbia spp. and Melaleuca spp. The ground layer is a variable combination of aquatic plants, sedges, forbs and grasses. Occurs on active Quaternary alluvial plains. Subject to channel flow and over-bank flow during the wet season. Commonly associated with major watercourses. Open water commonly occurs. Palustrine. (BVG1M: 34d). Vegetation communities in this regional ecosystem include: 2.3.16a: [RE not in use]²: This vegetation community has been amalgamated into 2.3.16. Billabongs (abandoned channels) on alluvial plains, commonly fringed with Eucalyptus camaldulensis and/or E. microtheca and, occasionally, Melaleuca spp. The ground layer is a variable combination of aquatic plants, sedges, forbs and grasses. Occurs on Quaternary alluvial plains. Subject to channel flow and over-bank flow during the wet season. Commonly associated with major watercourses. Open water commonly occurs. Palustrine. (BVG1M: 34d). 2.3.16x1: [RE not in use]²: This regional ecosystem has been amalgamated into 2.3.16. Billabongs (abandoned channels) on alluvial plains, fringed with Eucalyptus microtheca and Melaleuca spp. The ground layer is a variable combination of aquatic plants, sedges, forbs and grasses. Occurs on Quaternary alluvial plains on texture contrast soils in the Yappar River - Belmore Creek alluvial system. Areas of open water may occur. Palustrine. (BVG1M: 34d). |

| Special values | 2.3.16: Permanent and seasonal wetlands. Important breeding and feeding sites for water birds. 2.3.16a: Permanent and seasonal wetlands. Important breeding and feeding sites for water birds and freshwater crocodiles. 2.3.16x1: Seasonal wetland. Important feeding and moulting sites for water birds. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately, but not necessary to protect from fire. Protection depends on broad-scale management of surrounding country with small fires in surrounding areas used to break up country and limit extent of fire risk. It will occasionally burn in association with fires in surrounding country. ISSUES: Do not actively target burning of sedgelands. |
| Comments | 2.3.16: Threatened by introduction of ponded pasture species, and by high total grazing pressures around margins particularly during dry season. 2.3.16a: Threatened by high total grazing pressures around margins. 2.3.16x1: Threatened by high total grazing pressures around margins. |
1 Estimated extent is from version 13 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.
