| Special values | 12.9-10.1: Habitat for threatened plant species including Boronia keysii. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.1x1: Habitat for threatened plant species including Boronia keysii, Xanthostemon oppositifolius, Archidendron lovelliae, Macrozamia pauli-guilielmi. |
| 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: 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. A grassy system is especially important for species such as the eastern bristlebird and its habitat. 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 | 12.9-10.1: Restricted to wet coastal lowlands of the Sunshine Coast from Eudlo to Como. Subject to increasing pressure from rural subdivision. 12.9-10.1x1: Restricted to wet coastal lowlands north of Noosa. Subject to increasing pressure from rural subdivision. |
