| Structure code | Low Open Woodland |
| Description | Mixed low open woodland including Corymbia terminalis, Atalaya hemiglauca, Eucalyptus leucophylla, Hakea lorea subsp. lorea, Hakea chordophylla, Acacia cambagei and Corymbia aparrerinja with a scattered shrub layer mostly of Senna spp. and Eremophila spp. and very open ground layer of mostly annual species sometimes with Triodia molesta and Triodia brizoides. Occurs on hard metamorphic plains. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 1.11.10a: Mixed low open woodland including Corymbia terminalis, Atalaya hemiglauca, Hakea lorea subsp. lorea, Hakea chordophylla, Acacia cambagei and Corymbia aparrerinja with a scattered shrub layer mostly of Senna spp. and Eremophila spp. and very open ground layer of mostly annual species sometimes with Triodia molesta and Triodia brizoides. Occurs on hard metamorphic plains. Not a Wetland. (BVG1M: 19b). 1.11.10b: Mixed low open woodland including Eucalyptus leucophylla, Corymbia terminalis, Corymbia aparrerinja, Atalaya hemiglauca, Grevillea striata, Hakea spp., Acacia excelsa subsp. angusta and Acacia cambagei over a sparse ground layer dominated by short annual grasses and forbs. Treeless areas are common. Occurs on undulating landscapes of metamorphosed igneous rocks. Not a Wetland. (BVG1M: 19b). |
| Special values | 1.11.10: Potential habitat for NCA listed species: Eucalyptus nudicaulis. |
| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Low to moderate. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Ensure burns are undertaken across the landscape at a range of frequencies to create a mosaic of times since fire. Apply numerous small burns every year to achieve a mosaic and reduce risks of wildfire across vast areas of the landscape. Maintain burnt areas < 20%. ISSUES: Rainfall is a major factor affecting spinifex growth, such that a very wet year or a series of wet years may boost the spinifex fuel load leading to the possibility of extensive wildfire in subsequent years. Shrub diversity may decline over time since fire. Sparse ground layer may make burning difficult. b: Too frequent fire can promote annual grasses over perennial. Ensure areas with obligate seeders are left so that seed regeneration cycles can be maintained. Mixed shrubby woodlands contain fire-sensitive species and tend to grow in fire-sheltered areas. |
| Comments | 1.11.10: These are very open communities with very sparse ground cover. This vegetation community was previously mapped as 1.11.2x6. 1.11.10a: This vegetation community was previously mapped as 1.11.2x6a. Mixed low open woodland including Corymbia terminalis, Atalaya hemiglauca, Hakea spp., and Corymbia aparrerinja on bare metamorphic plains. 1.11.10b: This vegetation community was previously mapped as 1.11.2x6b. |
