Short description Shrubby woodland with Eucalyptus racemosa subsp. racemosa or E. dura on Cainozoic igneous rocks
Structure code Woodland
Description Woodland to low open woodland complex. Canopy trees include Eucalyptus racemosa subsp. racemosa, E. dura, Corymbia trachyphloia, E. carnea, Allocasuarina littoralis, Acacia spp. and Lophostemon confertus. Occurs on Cainozoic igneous rocks, especially rhyolite. Not a Wetland. (BVG1M: 9h).

Protected areas Mount Barney NP, Glass House Mountains NP, Moogerah Peaks NP, Main Range NP, Tewantin NP, Lamington NP, Springbrook NP, Noosa NP, Tuchekoi NP, Mount Coolum NP
Special values 12.8.20: Habitat for threatened plant species including Grevillea linsmithii, Arundinella grevillensis, Westringia sericea, Eucalyptus kabiana, Leionema gracile and near threatened species including Hibbertia hexandra, Melaleuca groveana, Comesperma breviflorum and Eucalyptus curtisii. Habitat for plants with restricted or disjunct distributions e.g. Grevillea whiteana. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus).
Fire management guidelines SEASON: Late summer to winter. INTENSITY: Low to moderate. INTERVAL: 7-25 years. Maintain longer fire intervals for Springbrook Plateau; these mainly non-grassy ecosystems should generally be left unburnt. INTERVAL_MIN: 7. INTERVAL_MAX: 25. STRATEGY: Aim for a burn mosaic of 40-60% over the burn area. Although, non-grassy versions of this RE should generally be left unburnt (e.g., Springbrook Plateau). A diversity of season and fire intensity is important, as well as spot ignition in cooler or moister periods to encourage mosaics. Late summer burns assist with maintaining control of fire intensity. ISSUES: Both grassy and non-grassy versions of the ecosystems exist; these different versions occur in varying proportion depending on location (e.g., on the Springbrook Plateau the non-grassy types are predominant). On Springbrook Plateau this RE should generally be managed as a wet sclerophyll that would have a very long fire interval and left unburnt so that the more mesic species can develop in the understorey. Avoid repeated low intensity fires. Fires that are too frequent will eliminate obligate seeding species. Fire frequency should be such as to allow obligate seeders to reach maturity and produce viable seed.
Comments 12.8.20: Eucalyptus campanulata is a conspicuous element at Springbrook. Frequent fire can favour fire-tolerant species at the expense of fire-sensitive species.
