Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Of concern

Short description Eucalyptus tereticornis subsp. tereticornis or E. tereticornis subsp. basaltica open forest on metamorphics +/- interbedded volcanics, usually on ridges, crests and upper slopes
Structure code Open Forest
Description Open forest to woodland with Eucalyptus tereticornis. Includes both E. tereticornis subsp. tereticornis and E. tereticornis subsp. basaltica. Other canopy species include Eucalyptus biturbinata, E. melliodora, Corymbia intermedia, E. longirostrata, E. eugenioides, Allocasuarina torulosa, E. moluccana, E. saligna, E. siderophloia and Angophora subvelutina. Occurs on ridges and upper slopes especially at higher altitudes on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. These occurrences are often associated with small areas of intermediate and basic volcanic rocks. Minor occurrences on low coastal ridges and upper slopes. Not a Wetland. (BVG1M: 9g).

Vegetation communities in this regional ecosystem include:
12.11.9x1: Eucalyptus montivaga open forest. Other canopy species can include Corymbia trachyphloia, E. acmenoides, Syncarpia glomulifera subsp. glomulifera and C. intermedia. Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Altitude >500m. Not a Wetland. (BVG1M: 8b).

Special values 12.11.9: Potential habitat for NCA listed species: Papillilabium beckleri. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.11.9x1: 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: Occurs on exposed ridges and crests but soils are heavy and retain moisture. May contain heath species in understorey. 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.
Comments 12.11.9: Often occurs as localised patches on ridge tops that are too small to map at 1:100 000 scale.
