Regional ecosystem details for 8.3.15
| Regional ecosystem | 8.3.15 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 2, (1), (3) |
| Estimated extent1 | Pre-clearing 900 ha; Remnant 2021 800 ha |
| Short description | Open water in river channels, waterholes and lagoons, and exposed stream beds and bars |
| Structure code | Bare |
| Description | Open water in river channels, waterholes and lagoons, and exposed stream bed and bars. Usually devoid of emergent vegetation although scattered trees and shrubs such as Melaleuca viminalis or Melaleuca spp. may be present and aquatic species may be abundant particularly in waterholes and lagoons. Stream channels and lagoons, and exposed stream beds and bars of watercourses on level plains to rolling mountains. Geology mapped as Qha, Qa and Qf (Quaternary sand, gravel, silt and clay; active stream channels, low terraces, floodplain alluvium, flood-out sheets and small fans). Riverine. (BVG1M: 16d). |
| Protected areas | Conway NP |
| Special values | 8.3.15: Essential habitat for a variety of aquatic and riparian invertebrates, frogs and other fauna. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Non-flammable. |
| Comments | 8.3.15: Associated with all streams, and therefore the regional ecosystems 8.3.3 and 8.3.1. Largest mappable areas occur in Cattle Creek, Hatton Creek and the Pioneer River in the Pioneer Valley west of Mackay. Also at Repulse Creek in Conway Range National Park. Areas surrounded by cleared land tend to be in poorer condition, with weed species sometimes the only species present, and the hydrology altered substantially (especially where affected by dams, weirs and causeways). The water quality may also be affected in areas which have been surrounded by agriculture for a long time. |
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.
