| Regional ecosystem | 4.3.22 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Palustrine |
| Biodiversity status | Endangered |
| Subregion | 2 |
| Estimated extent1 | Pre-clearing 200 ha; Remnant 2021 200 ha |
| Short description | Springs on recent alluvia and fine-grained sedimentary rock |
| Structure code | Bare |
| Description | Springs. Occurs on recent alluvia and fine-grained sedimentary rock (shales) and fed by the Great Artesian Basin. Palustrine. (BVG1M: 34e). |
| Supplementary description | Habermehl (1982); Ponder and Clark (1990); Fairfax and Fensham (2002); Fensham et al. (2004) |
| Protected areas | Elizabeth Springs CP |
| Special values | 4.3.22: Habitat for endemic species including fish (Elizabeth Springs goby Chlamydogobius micropterus); the snail Jardinella isolata; and endangered plant species including Eriocaulon carsonii and Myriophyllum artesium. |
| Fire management guidelines | SEASON: Wet to early dry season when soil is moist. INTENSITY: Low. INTERVAL: Fire return interval flexible. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Springs should not be intentionally burnt. Burn surrounding vegetation at intervals compatible with fuel availability, seasonal conditions and grazing pressure. |
| Comments | 4.3.22: Springs in Tertiary aquifers may exist, but are poorly known. All the springs are within Great Artesian Basin discharge areas. Impacted by artificial extraction, excavation, pig rooting and stock trampling. Springs in Tertiary aquifers may exist, but are poorly known. |
