| Short description | Eucalyptus crebra woodland on coarse-grained sedimentary rocks |
| Structure code | Woodland |
| Description | Eucalyptus crebra and/or E. melanophloia +/- E. populnea shrubby woodland. Eucalyptus melanophloia and/or E. crebra predominate and form a distinct but open canopy. E. populnea is commonly present and may be locally dominant particularly on lower slopes. A low tree to tall shrub layer usually dominated by a range of species including Eremophila mitchellii, Acacia decora, A. longispicata spp. longispicata and A. excelsa is present. A low shrub layer with Petalostigma pubescens and other species is formed in places. The ground layer is variable in cover and composition, but composed mainly of grasses. Occurs on the lower slopes of scarp retreats, associated with dissected tablelands. Associated soils are generally moderately deep, acidic, sandy, yellow earths and sandy-surfaced texture contrast soils formed from medium to coarse-grained sediments. Not a Wetland. (BVG1M: 12a). Vegetation communities in this regional ecosystem include: 11.10.7a: Eucalyptus crebra +/- Callitris glaucophylla +/- Angophora leiocarpa +/- Eucalyptus spp. woodland. Eucalyptus crebra predominates and forms a distinct but discontinuous canopy (16-20 m high). In places, Angophora leiocarpa forms part of the canopy. The low tree layer (12-16 m high) is dominated by Callitris glaucophylla. Scattered tall and low shrubs may be present. The ground layer is open to dense, and dominated by perennial grasses, usually Aristida spp. or Themeda triandra. Occurs on the lower slopes of scarp retreats, associated with dissected tablelands. Associated soils are generally moderately deep, acidic, sandy, yellow earths and sandy-surfaced texture contrast soils formed from medium to coarse-grained sediments. Not a Wetland. (BVG1M: 12a). |

| Special values | 11.10.7: Potential habitat for NCA listed species: Acacia islana, Acacia sp. (Ruined Castle Creek P.I.Forster+ PIF17848), Eucalyptus tereticornis subsp. rotunda, Sannantha brachypoda. |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Moderate to high. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Burn less than 10-30% in any year. Burn surrounding vegetation under conditions of good soil moisture and when plants are actively growing throughout the year so that wildfires will be very limited in extent. Fire exclusion not necessary. ISSUES: Best protection from wildfires is probably the creation of a multi-aged mosaic in surrounding vegetation and perimeter burning. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.10.7: The occurrences in subregion 14 are unusual in that they are coastal. |
