| Description | Woodland to open forest generally with Eucalyptus tereticornis subsp. tereticornis or E. tereticornis subsp. basaltica +/- E. eugenioides. Other species present vary from place to place but commonly include E. crebra, Corymbia intermedia, E. acmenoides, E. biturbinata, E. longirostrata, E. melliodora, C. trachyphloia, C. citriodora subsp. Variegata, Lophostemon confertus (tree form and whipstick form), Angophora subvelutina and Allocasuarina torulosa. Occurs at higher altitudes on crests, upper slopes and elevated valleys and plains on Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 9g). |

| Special values | 12.12.23: Potential habitat for NCA listed species: Eucalyptus taurina, Paspalidium grandispiculatum and Coleus torrenticola. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Plan for low to moderate. Unplanned occasional high intensity wildfire will occur. INTERVAL: 4-8 years maintains a healthy grassy system. 8-20 years for shrubby elements of understorey. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Aim for 40-60% mosaic burn. Needs disturbance to maintain RE structure (eucalypt overstorey with open understorey of predominantly non-rainforest species). ISSUES: Frequent fire is needed to maintain understorey integrity, keeping more mesic species low in the profile of the understorey so that other species can compete. It is essential that wildfires are not the sole source of fire in this ecosystem. High intensity fires occur periodically through time, however frequent low to moderate intensity fires will create the disturbance required to keep the understorey diverse. A follow-up burn soon after a high intensity wildfire can be considered to reduce germinating/resprouting mesic species. Impact of fire on NCA listed species is uncertain, e.g., Paspalidium grandispiculatum has robust rhizomes and may be expected to be fire tolerant. High disturbance from fire, grazing and clearing has led to high non-native cover. Presence of a blady grass understorey may indicate poor fire management. |
