| Short description | Eucalyptus leucophloia low open woodland on sandstone plateaus |
| Structure code | Low Open Woodland |
| Description | Eucalyptus leucophloia low open woodland. Mixed shrub layer commonly dominated by Acacia spp. Ground cover of Triodia spp. and annual grasses. Occurs on skeletal soils on sandstone plateaus. Not a Wetland. (BVG1M: 19a). Vegetation communities in this regional ecosystem include: 1.10.4a: Eucalyptus leucophloia low open woodland. Acacias usually prominent, forming shrublands in the far south. Ground cover of Triodia spp. and annual grasses. Occurs on near horizontally bedded sandstones and conglomerates; skeletal soils. Not a Wetland. (BVG1M: 19a). 1.10.4b: Eucalyptus leucophloia low open woodland over Triodia spp. or annual grasses. Occasional Eucalyptus pruinosa and C. grandifolia and Melaleuca viridiflora on lower slopes. Sparse low shrubs include Acacia spp., Grevillea dryandri, Terminalia canescens and Petalostigma quadriloculare. Terminalia bursarina on creek lines. Occurs on rocky hills on pre-Cambrian sediments and interbedded acid volcanics; skeletal soils, shallow earthy sands. Not a Wetland. (BVG1M: 19a). |

| Special values | 1.10.4: Potential habitat for NCA listed species: Trachymene glandulosa. |
| 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: Too frequent fire can promote annual grasses over perennial. 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. a: Recruitment of Acacias is stimulated by fire but they are also sensitive to high frequency intense fires. |
| Comments | 1.10.4a: Dominance by Acacia spp. is ephemeral and related to fire history. |
