Short description Eucalyptus camaldulensis woodland on channels and levees
Structure code Woodland
Description Eucalyptus camaldulensis fringing woodland with Melaleuca bracteata on levees of smaller channels and M. fluviatilis or M. leucadendra on those of larger ones where water is available for extended periods each year. Lophostemon grandiflorus usually present, occasional Terminalia aridicola. Eucalyptus microtheca or E. leucophylla on finer textured soils. Occurs on recent levees and channel deposits of larger tributaries; alluvial soils. Riverine. (BVG1M: 16a).

Vegetation communities in this regional ecosystem include:
1.3.7a: Eucalyptus camaldulensis fringing woodland to closed forest, usually with Lophostemon grandiflorus and Melaleuca leucadendra and/or M. fluviatilis. Occurs on recent levees and channel deposits of major watercourses and larger tributaries. Riverine. (BVG1M: 16a).
1.3.7b: Eucalyptus camaldulensis fringing woodland, usually with Lophostemon grandiflorus and Melaleuca bracteata and/or M. dissitiflora. Occurs on recent levees and channel deposits of medium and smaller tributaries which are dry for most of the year; alluvial soils. Riverine. (BVG1M: 16a).
1.3.7c: [RE not in use]²: This vegetation community is now mapped as 1.3.13a. Eucalyptus leucophylla woodland often with E. camaldulensis, Corymbia terminalis and Acacia cambagei with ground layer dominated by Bothriochloa ewartiana and/or Triodia longiceps. Occurs on channel deposits in minor watercourses. Riverine. (BVG1M: 19b).
1.3.7d: [RE not in use]²: This vegetation community is now mapped as 1.3.7a. Melaleuca leucadendra, Lophostemon grandiflorus, Eucalyptus camaldulensis and Livistona rigida fringing forest where there is permanent water or the channel is confined by topography; E. camaldulensis and Lophostemon grandiflorus woodland with a dense shrub layer dominated by Vitex trifolia, Flueggea leucopyrus and Melaleuca spp. between permanent holes and where the channel is not closely confined by topography. Occurs on alluvial deposits along major watercourses; alluvial soils. Riverine. (BVG1M: 22c).
1.3.7e: [RE not in use]²: This vegetation community is now mapped as 1.3.7a. Waterholes with aquatic plants with or without fringing woodland of Eucalyptus camaldulensis and/or Melaleuca leucadendra and/or Melaleuca fluviatilis and/or Eucalyptus microtheca. Waterholes within major stream channels. Riverine. (BVG1M: 16d).
1.3.7f: Woodland including Eucalyptus camaldulensis, Lophostemon grandiflorus, Melaleuca argentea, Terminalia bursarina, Lysiphyllum cunninghamii and Acacia holosericea. Occurs on within-channel deposits and levees of major watercourses; alluvial soils. Riverine. (BVG1M: 16a).
1.3.7g: Eucalyptus camaldulensis woodland often with Corymbia capricornia and Eucalyptus miniata with a mixed shrub layer in which Melaleuca viridiflora is prominent. Ground layer of tussock grasses and Triodia spp. Occurs on watercourses in gorges in pre-Cambrian sandstone formations. Riverine. (BVG1M: 16a).

Special values 1.3.7: Important seasonal water bird habitat; regional corridor for fauna.
Fire management guidelines SEASON: Do not burn deliberately. INTENSITY: Low. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. May be burnt in association with surrounding spinifex vegetation types. Low intensity fire in surrounding fire-adapted areas will reduce fire encroachment. ISSUES: A hydrology-driven habitat (not fire-driven) i.e. fuel loads do not really build up. Do not actively target for prescribed burning but, as these REs are not particularly fire sensitive, they can tolerate occasional burns. Overgrazing can reduce fuel loads and give woody species a competitive advantage.
Comments 1.3.7: Includes a number of within-channel ecosystems. Survey required to verify condition and faunal values. Severely degraded by high total grazing pressure. 1.3.7f: Terminalia bursarina is a key species for this subunit. Occurs in the northern part of the bioregion. Subject to degradation by high total grazing pressure.

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.
