| Special values | 10.3.15: Seasonal wetland values for water bird nesting and feeding. Habitat for newly discovered species Goodenia sp. (Torrens Creek E.J.Thompson+ HUG754). The only recorded locations of Calostemma luteum and Hypoxis hygrometrica in the DEU occur in 10.3.15. The seasonal wetlands are in this ecosystem are important for water bird nesting and feeding, and aquatic species and potential habitat for the endangered species, Eriocaulon aloefolium, Eriocaulon giganticum, and Ammannia robertsii. As for other riparian zones, this ecosystem has important values for stabilising top soils, providing corridors for wildlife, and for trapping soil and maintaining water quality. 10.3.15d: Potential habitat for vulnerable species Acacia crombiei. |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Most of the vegetation communities will be difficult to burn. Mosaic 50-80% of area targeted. ISSUES: Grazing can impact heavily and combined with low rainfall fuel loads will be low making burning difficult. Can be advantageous to burn in year following good rains to manage currant bush and false sandalwood. Eucalypts such as E. dallachiana and E. coolabah germinate and recruit following rainfall; do not burn to thin as attrition will reduce density in drought years. |
| Comments | 10.3.15: Subject to soil and pasture degradation. Potential for invasion by weed species including *Cryptostegia grandiflora (rubber vine) and Parkinsonia aculeata, and degradation by high total grazing pressure. Pigs are attracted to these areas causing major soil disturbance, fouling of water holes, and destroying wildlife and habitat. 10.3.15b: Relatively uncommon ecosystem only found in the driest parts of the bioregion in subregion 1 represented by small sandy closed depressions and edges of some larger lakes. 10.3.15c: Widespread but does not occupy extensive areas. 10.3.15d: Uncommon ecosystem only known from subregion 1 near Ludgate Hill. 10.3.15e: An uncommon ecosystem occurring in northern parts of subregion 2. It has been recorded at Lake Moocha, Webb Lake, The Dry Swamp and Thirlestone. 10.3.15f: Occurs mostly on the perimeter of Lake Galilee and also at Lake Barcoorah. 10.3.15g: Uncommon ecosystem occurring mostly in northern parts of subregion 2. 10.3.15h: Uncommon ecosystem only known from subregion 1. 10.3.15i: A rare ecosystem occurring mostly near Barcaldine. 10.3.15j: Uncommon ecosystem known from near Webb Lake, Lake Moocha and the Dry Swamp. Further survey required for comprehensive floristic composition. 10.3.15l: Very rare ecosystem only known from the perimeter of Lake Galilee. *Vachellia farnesiana is present as scattered shrubs. 10.3.15m: Very rare ecosystem only known from Lake Galilee. Naturalised species associated with this regional ecosystem include *Echinochloa colona, *Cenchrus ciliaris and *Chloris virgata, which may dominate the ground layer. 10.3.15n: Very rare ecosystem only known from near Lake Buchanan. 10.3.15o: Very rare ecosystem only known from Lake Galilee. |
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.
