| Short description | Melaleuca citrolens +/- M. foliolosa +/- M. viridiflora low open woodland on plains |
| Structure code | Low Open Woodland |
| Description | Low open woodland of Melaleuca citrolens (scrub teatree) and often also M. viridiflora (broad-leaved teatree) and M. foliolosa (scaly leaved teatree). In places, these species occur as multi-stemmed shrubs rather than single-stemmed low trees. A sparse shrub layer is sometimes present. The short, sparse ground layer is dominated by annual graminoids with Fimbristylis spp., Schizachyrium spp. (fire grass) and Aristida spp. (three-awned speargrass) being the most commonly encountered taxa. Occurs on low undulating rises. Not a Wetland. (BVG1M: 21b). |

| Fire management guidelines | SEASON: Early to mid-dry season, with occasional storm burn or late dry season burn of limited area. INTENSITY: High, but low to moderate are more likely during the early to mid-dry season. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: A mosaic of early dry season fires will prevent extensive wildfires in the late dry season and preserve areas for later storm-burning. Storm time and late dry season burns are used to maintain suitable vegetation structure. Burn less than 30% in any year. ISSUES: Lack of fire or low intensity burns can lead to overabundant broad-leaved ti-tree. High intensity fires may be difficult to achieve because of low fuel availability and accumulation rates and typically moister conditions. High intensity fires around storm time will promote a better developed ground layer. Active burning early in the dry season creates a mosaic to minimise the spread of wildfire late in the dry season. Early burns will usually burn with low intensity and will not control broad-leaved ti-tree. |
