| Protected areas | Main Range NP |
| Special values | 12.8.12: 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. 8-15 years for shrubby elements of understorey. INTERVAL_MIN: 4. INTERVAL_MAX: 15. STRATEGY: Aim for 40-60% mosaic burn. Needs disturbance to maintain RE structure (eucalypt overstorey with open understorey of predominantly non-rainforest species). ISSUES: This RE occurs as two very small polygons situated on high elevation plateaus. As such it is drier than adjacent moist REs, but should be managed as moist given its proximity to other moist units. 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 | 12.8.12: Eucalyptus obliqua is a temperate adapted species. Extends from Tasmania to Mistake Plateau. Known from only a few small populations on Main Range in southeast Queensland. |
