| Description | Eucalyptus fibrosa subsp. fibrosa woodland +/- Corymbia citriodora subsp. variegata, E. acmenoides or E. portuensis, Angophora leiocarpa, E. major. Understorey often sparse. Localised occurrences of Eucalyptus sideroxylon. Occurs on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 12a). Vegetation communities in this regional ecosystem include: 12.9-10.19a: Corymbia henryi and/or Eucalyptus fibrosa subsp. fibrosa open forest. Other commonly associated species include, Corymbia citriodora subsp. variegata, E. carnea, E. siderophloia, E. crebra and E. major. Occurs in coastal areas on Cainozoic and Mesozoic sediments.

| Special values | 12.9-10.19: Habitat for threatened plant species including Macrozamia parcifolia. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.19a: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. 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. Control of weeds (e.g., Lantana camara, balloon cotton-bush Gomphocarpus physocarpus) with fire might be required. There is evidence that the spiral leaf Macrozamias (e.g. M. parcifolia) decline in health if fire interval is greater than 6 years. |
| Comments | 12.9-10.19: This RE has a very patchy distribution and often occurs as patches too small to map at 1:100 000 scale. 12.9-10.19a: This RE is a mesic variant of 12.9-10.19. It has a very patchy distribution and often occurs as patches too small to map at 1:100 000 scale. Southern parts of bioregion. |
