| Short description | Eucalyptus pilularis tall open forest on sedimentary rocks |
| Structure code | Tall Open Forest |
| Description | Eucalyptus pilularis tall open forest with shrubby understorey. Other species include Syncarpia glomulifera subsp. glomulifera, S. verecunda, Corymbia intermedia, Angophora woodsiana and Eucalyptus microcorys in coastal areas and species of RE 12.9-10.5 in drier sub coastal areas. Eucalyptus pilularis sometimes extends onto colluvial lower slopes. Occurs on Cainozoic and Mesozoic sediments especially sandstone. Not a Wetland. (BVG1M: 8b). Vegetation communities in this regional ecosystem include: 12.9-10.14a: Open forest of Eucalyptus grandis, Lophostemon confertus, E. microcorys, Syncarpia glomulifera subsp. glomulifera +/- E. pilularis. Occurs on Cainozoic and Mesozoic sediments especially sandstone in wet gullies and southern slopes. Not a Wetland. (BVG1M: 8a). 12.9-10.14b: Eucalyptus pilularis open forest. Other canopy species may include Angophora woodsiana, Eucalyptus baileyana, Corymbia henryi, C. trachyphloia, E. taurina, and E. microcorys. Occurs in dry sub coastal areas on Cainozoic and Mesozoic sediments especially quartzose sandstone. Not a Wetland. (BVG1M: 8b). |

| Special values | 12.9-10.14: Potential habitat for NCA listed species: Acacia attenuata, Boronia rivularis, Caustis blakei subsp. macrantha, Eucalyptus taurina, Leptospermum luehmannii, Phaius australis and Zieria bifida. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.14a: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.14b: Habitat for threatened plant species including Eucalyptus taurina. 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: 8-20 years for shrubby elements of understorey. INTERVAL_MIN: 8. 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. Getting an effective burn will be difficult. |
| Comments | 12.9-10.14: Mainly coastal. Extensively cleared for horticulture, exotic pine plantations and rural residential development in some locations. The clearing has also resulted in fragmentation. 12.9-10.14a: Tends to grade upslope into 12.9-10.14. Sunshine Coast and inland to Peachester. Minor occurrence on NSW border south of Mt Barney. Extensively cleared for horticulture, exotic pine plantations and rural residential development in some locations. 12.9-10.14b: Helidon Hills to Crows Nest area. Cleared for horticulture, exotic pine plantations and rural residential development in some locations. |
