| Regional ecosystem | 3.3.11 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Riverine |
| Biodiversity status | Endangered |
| Subregion | 5, 2, 1, (6), (7.9), (9.3) |
| Estimated extent1 | Pre-clearing 4000 ha; Remnant 2021 4000 ha |
| Short description | Melaleuca leucadendra +/- Corymbia tessellaris woodland on alluvium derived from metamorphic rocks |
| Structure code | Woodland |
| Description | Melaleuca leucadendra (weeping paperbark) and Corymbia tessellaris (Moreton Bay ash) woodland +/- Blepharocarya involucrigera (Rose Butternut) +/- Buchanania arborescens (native mango). A sparse sub-canopy usually contains canopy species, Lophostemon spp. and Leptospermum madidum. The grassy ground layer is generally sparse to mid-dense and includes Imperata cylindrica (blady grass), Mnesithea rottboellioides and Panicum trichoides . Occurs on alluvium derived from metamorphics. Riverine. (BVG1M: 22c). |

| Protected areas | Rinyirru (Lakefield) NP (CYPAL), Kalkajaka NP (CYPAL), Melsonby (Gaarraay) NP (CYPAL), Palmer Goldfield RR, Black Mountain NP |
| Special values | 3.3.11: Important wildlife corridors. |
| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. Burn only under mild conditions. INTERVAL: 3-5 years. INTERVAL_MIN: 3. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Patch burn early in the dry season so that wildfires will be very limited in extent. ISSUES: Restrict extent and intensity of fires. |
| Comments | 3.3.11: Only small areas in bioregion, more extensive in Einasleigh Uplands bioregion. Threatened in places by alluvial gold mining. Heavily infested with weeds including Cryptostegia grandiflora, Cynodon dactylon var. dactylon* (green couch) and Mesosphaerum suaveolens*. |
