Regional ecosystem details for 12.5.9
| Regional ecosystem | 12.5.9 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Contains Palustrine |
| Biodiversity status | Of concern |
| Subregion | 8, 9, (4), (2) |
| Estimated extent1 | Pre-clearing 12000 ha; Remnant 2021 7000 ha |
| Short description | Sedgeland to heathland in low lying areas on complex of remnant Tertiary surface and Tertiary sedimentary rocks |
| Structure code | Sedgeland |
| Description | Sedgeland to heathland often with emergent Eucalyptus latisinensis. Characteristic shrubs include Leptospermum spp., Leucopogon spp., Ricinocarpos pinifolius, Strangea linearis, Brachyloma daphnoides, Persoonia virgata, Xanthorrhoea spp., Styphelia viridis, Monotoca scoparia, Woollsia pungens and stunted Allocasuarina littoralis. Includes minor seepage areas containing Banksia robur and Xanthorrhoea fulva. Occurs on complex of remnant Tertiary surfaces and Tertiary sedimentary rocks. Lower slopes. Contains Palustrine. (BVG1M: 29a). Vegetation communities in this regional ecosystem include: 12.5.9a: Melaleuca nodosa low open forest to low closed-forest +/- emergent eucalypts. Occurs on poorly drained areas on remnant Tertiary surfaces including lower slopes. Contains Palustrine. (BVG1M: 21b). |

| Protected areas | Burrum Coast NP, Great Sandy NP, Poona NP, Bingera NP, Littabella NP, Noosa NP, Deepwater NP, Bingera CP1, Bingera CP2 |
| Special values | 12.5.9: Habitat for near threatened plant species including Melaleuca cheelii. |
| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Moderate. INTERVAL: 8-15 years. INTERVAL_MIN: 8. INTERVAL_MAX: 15. STRATEGY: Aim for a burn mosaic of 40-60%. Do not re-light areas remaining unburnt after a planned burn. Burn in association with surrounding ecosystems. ISSUES: Often contains obligate seed regenerating species (e.g. geebung Persoonia virgata, Hakea actites and wedding bush Ricinocarpus pinifolius) and as such, the application of frequent fire may reduce species richness if the intervals between fire are not sufficient for plants to produce seed. Too frequent a fire frequency may result in a net loss of nutrients over time from an already nutrient poor system. |
| Comments | 12.5.9a: Habitat is being cleared or impacted by rural residential development in some areas. |
