| Short description | Acacia cambagei low open woodland +/- Senna artemisioides subsp. oligophylla +/- Eremophila spp. on minor drainage lines and alluvial plains |
| Structure code | Low Open Woodland |
| Description | Acacia cambagei low open woodland with an open shrub layer comprising juvenile Acacia cambagei, Senna artemisioides subsp. oligophylla and Eremophila spp. frequently present. The very sparse to open ground layer commonly includes Enteropogon acicularis, Eragrostis xerophila, Aristida latifolia and Sporobolus actinocladus, with Bothriochloa ewartiana and Chrysopogon fallax locally abundant. A variety of ephemeral forbs occur infrequently but may be seasonally co-dominant. Occurs on minor drainage lines and alluvial plains adjacent to and draining dissected residuals and plateaus. Soils generally gravelly loams to deep red clays and texture contrast soils. Not a Wetland. (BVG1M: 26a). Vegetation communities in this regional ecosystem include: 5.3.10a: Acacia cambagei low open woodland with an open shrub layer comprising juvenile Acacia cambagei, Senna artemisioides subsp. oligophylla and Eremophila spp. frequently present. The very sparse to open ground layer commonly includes Enteropogon acicularis, Eragrostis xerophila, Aristida latifolia and Sporobolus actinocladus, with Bothriochloa ewartiana and Chrysopogon fallax locally abundant. A variety of ephemeral forbs occur infrequently but may be seasonally co-dominant. Occurs on minor drainage lines adjacent to and draining dissected residuals and plateaus. Soils generally gravelly loams to deep red clays and texture contrast soils. Riverine. (BVG1M: 26a). 5.3.10b: Acacia cambagei low open woodland with an open shrub layer comprising juvenile Acacia cambagei, Senna artemisioides subsp. oligophylla and Eremophila spp. frequently present. The very sparse to open ground layer commonly includes Enteropogon acicularis, Eragrostis xerophila, Aristida latifolia and Sporobolus actinocladus, with Bothriochloa ewartiana and Chrysopogon fallax locally abundant. A variety of ephemeral forbs occur infrequently but may be seasonally co-dominant. Occurs on alluvial plains adjacent to and draining dissected residuals and plateaus. Soils generally gravelly loams to deep red clays and texture contrast soils. Not a Wetland. (BVG1M: 26a). |

| Protected areas | Diamantina NP, Pullen Pullen SWR, Lochern NP, Welford NP, Goneaway NP |
| Special values | 5.3.10: Potential habitat for NCA listed species: Eremophila stenophylla. |
| Fire management guidelines | SEASON: Various (wet season or winter). INTENSITY: Low - moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter when fire is more easily controlled. ISSUES: Rarely burns due to low fuel loads. |
| Comments | 5.3.10a: Will be mapped in future releases. 5.3.10b: Will be mapped in future releases. |
