Regional ecosystem details for 11.10.14
| Regional ecosystem | 11.10.14 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Palustrine |
| Biodiversity status | Endangered |
| Short description | Springs associated with sandstone |
| Structure code | Bare |
| Description | Springs. Associated with quartzose sandstone ranges. Palustrine. (BVG1M: 34e). |
| Supplementary description | Fensham and Fairfax (2002); Fensham et al. (2004) |
| Special values | 11.10.14: Habitat for the threatened species including Arthraxon hispidus and endemic snails (Ponder and Clarke 1990). Disjunct populations of coastal plant species. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Depending on position in the landscape, protection depends on broad-scale management of surrounding country, with numerous small fires throughout the year so that wildfires will be very limited in extent. ISSUES: If burning is to occur then implement when water level is deep enough to protect the bases of aquatic plants. Sedges are disadvantaged by repeated fires. Impact of fire on rare and threatened plants associated with mound springs that include Arthraxon hispidus and Dimeria sp. (Salvator Rosa R.J.Fensham RJF3643) should be considered. Boggomosses/springs can bounce back following fire but care should be taken where a dry peat layer has developed (particularly in degraded situations). Fire is an option for control of weeds (possibly in ungrazed situations). If riparian areas need to be burnt to reduce fuel loads then burning should occur when there is good soil moisture and active growth. |
| Comments | 11.10.14: All the springs are within Great Artesian Basin recharge areas. Impacted by excavation, pig rooting, stock and feral horse trampling, artificial extraction from the aquifer, inundation by impoundments and the introduction of ponded pastures. |
