| Special values | 12.5.1: Potential habitat for NCA listed species: Bertya pedicellata, Caustis blakei subsp. macrantha, Eucalyptus taurina, Grevillea quadricauda, Lasiopetalum sp. (Proston J.A.Baker 17), Melaleuca formosa, Paspalidium grandispiculatum and Pomaderris clivicola. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.1a: Habitat for threatened plant species including Paspalidium grandispiculatum, Grevillea quadricauda, Lasiopetalum sp. (Proston). 12.5.1b: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.1c: Habitat for threatened plant species including Eucalyptus taurina, Paspalidium grandispiculatum and Grevillea quadricauda. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.1g: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-15 years. INTERVAL_MIN: 4. INTERVAL_MAX: 15. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. |
| Comments | 12.5.1: Isolate of RE with Eucalyptus dura locally prominent at Moggill on Brisbane's western outskirts. Occurs in sub coastal parts of bioregion. Extends into adjacent Brigalow Belt bioregion. 12.5.1a: Occurs in Tarong area. 12.5.1b: Occurs in sub coastal parts of Cooloola Shire. 12.5.1c: Occurs mainly in the Helidon Hills. 12.5.1e: Occurs in the Burnett area. 12.5.1f: Occurs in the Burnett area. 12.5.1g: Occurs in the Nathan, Mt Gravatt area. |
