| Short description | Mixed grassland to open grassland including Eragrostis sp., Aristida sp., Enneapogon sp., Iseilema sp., Chloris sp. or Dichanthium sp. on non-basalt derived alluvial deposits |
| Structure code | Tussock Grassland |
| Description | Variable mixed grassland including Eragrostis spp., Aristida spp., Enneapogon spp., Iseilema spp., Chloris spp. or Dichanthium spp. These grasslands may have isolated trees or small clumps of Eucalyptus leptophleba (Molloy red box) and/or E. microneura (Georgetown box) and/or Melaleuca viridiflora (broad-leaved paperbark) and/or M. citrolens (scrub teatree) scattered across them. Occurs on alluvial deposits that are not derived from basalt soils (as compared with 9.3.25). Contains Palustrine. (BVG1M: 32a). Vegetation communities in this regional ecosystem include: 9.3.26a: Grassland to open grassland on non-basalt derived alluvial deposits. These grasslands may have isolated trees or small clumps of various Eucalyptus spp. or Melaleuca spp. Occurs on non-basalt derived alluvium. Not a Wetland. (BVG1M: 32b). 9.3.26b: Swamps and run-on areas in grassland to open grassland on non-basalt derived alluvial deposits. Occurs on swamps and run-on areas. Palustrine. (BVG1M: 34d). |
| Protected areas | Littleton NP, Girringun NP, Blackbraes NP, Littleton RR, Rungulla NP |
| Special values | 9.3.26: Significant habitat particularly for herbivores such as macropods and arboreal mammals. |
| Fire management guidelines | SEASON: Late wet/early dry season when there is good soil moisture. INTENSITY: Various. Mainly low, but also moderate. INTERVAL: > 5 years. INTERVAL_MIN: 5. INTERVAL_MAX: 50. STRATEGY: Begin burning soon after the wet season so that fires will carry only a small distance. Patchy burns are preferred. Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. Where woody thickening is an issue, implement burns soon after high rainfall events, before woody seedlings become established. ISSUES: Patchy burning provides an appropriate mix of fresh and older tussocks and regenerates associated herbs. b: Typically non-flammable. |
| Comments | 9.3.26: Occurs in patches though-out the west and central bioregion. 9.3.26a: Occurs in patches though-out the west and central bioregion. 9.3.26b: Occurs in patches though-out the west and central bioregion. |
