| Description | Springs. Occurs on springs on recent alluvium. Palustrine. (BVG1M: 34e). Vegetation communities in this regional ecosystem include: 2.3.39a: Springs. Occurs on springs on recent alluvium. Palustrine. (BVG1M: 34e). 2.3.39b: [RE not in use]²: This vegetation community has been amalgamated into 2.3.39a. Aristida hygrometrica or Eriachne mucronata or Oxychloris spp. tussock grassland. Includes extinct mound springs with Eucalyptus camaldulensis +/- Pandanus tectorius woodland or Eucalyptus microtheca woodland or Corymbia confertiflora woodland. Occurs on artesian springs. Palustrine. (BVG1M: 34e). |
| Supplementary description | Fairfax and Fensham (2002); Fensham et al. (2004) |
| Special values | 2.3.39: Rare examples of peat development in tropical environments, but no specialised organisms identified. 2.3.39a: Rare examples of peat development in tropical environments, but no specialised organisms identified. 2.3.39b: Rare examples of peat development in tropical environments, but no specialised organisms identified. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Low intensity fire in surrounding fire-adapted areas will reduce fire encroachment. ISSUES: Ensure sufficient soil moisture to protect peat layer and fire-sensitive softwood species. Presence of high biomass grasses and rubbervine may increase fire risks. |
| Comments | 2.3.39: Peat mounds have developed in some instances. All the springs are within Great Artesian Basin discharge areas. The springs have been dramatically affected by artificial water extraction. Impacted by excavation and degraded by stock trampling and pig diggings. 2.3.39a: Peat mounds have developed in some instances. Was previously partly mapped as 2.3.39b. All the springs are within Great Artesian Basin discharge areas. The springs have been dramatically affected by artificial water extraction. Impacted by excavation and degraded by stock trampling and pig diggings. 2.3.39b: Peat mounds have developed in some instances. Was previously mapped as 2.3.33x1. All the springs are within Great Artesian Basin discharge areas. The springs have been dramatically affected by artificial water extraction. Impacted by excavation and degraded by stock trampling and pig diggings. |
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.
