Regional ecosystem details for 2.3.38

Regional ecosystem 2.3.38
Vegetation Management Act class Of concern
Wetlands Palustrine
Biodiversity status Endangered
Subregion 9
Estimated extent1 Pre-clearing 700 ha; Remnant 2021 700 ha
Short description Seasonal swamps. Mixed grasslands and sedgelands in closed depressions with Eucalyptus camaldulensis fringes on plateau surfaces
Structure code Sedgeland
Description Seasonal swamps. Mixed grasses and sedges, including Pseudoraphis spinescens, Cyperus spp. and Eragrostis spp. A wooded fringe of Eucalyptus camaldulensis usually occurs. Occurs in closed depressions on deep weathered Mesozoic plateau surfaces; yellow earths and solodised solonetz. Palustrine. (BVG1M: 34d).

Vegetation communities in this regional ecosystem include:
2.3.38x1: [RE not in use]²: This regional ecosystem is now mapped as 2.3.48. Shallow, seasonal, hypersaline lakes with a combination of grasses and sedges, including Eragrostis parviflora, Diplachne fusca var. fusca, Pseudoraphis spinescens, Schoenoplectiella lateriflora and Eleocharis philippinensis. A wooded fringe of Eucalyptus camaldulensis commonly occurs. Low sandy deposits on the western margins may occur. Open water is common, but seasonal. Occurs in large, closed depressions on Mesozoic sandstone plateaus (Gilberton Plateau subregion). Brown sandy clay soils. Lacustrine. (BVG1M: 34a).

Protected areas Rungulla RR, Rungulla NP
Special values 2.3.38: Seasonal wetland. Important feeding sites for water birds.
Fire management guidelines SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 3-5 years. INTERVAL_MIN: 3. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Sedges are disadvantaged by repeated high intensity fires. Low intensity fires help to maintain open structure. Mosaic helps protect animal habitat and food. Can be burnt when water level is deep enough to protect bases of sedges.
Comments 2.3.38: This regional ecosystem is currently rare but poorly known. More information required to verify description and extent. 2.3.38x1: A rare ecosystem with limited extent.

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
