| Short description | Melaleuca tamariscina tall open shrubland to low woodland on Cainozoic sand plains and/or remnant surfaces |
| Structure code | Tall Open Shrubland |
| Description | Melaleuca tamariscina tall open shrubland to low woodland with occasional emergent trees of Eucalyptus persistens or Corymbia dallachiana. A ground layer of Triodia spp. is usually present. Occurs on Cainozoic sandplains often on tops of mesas or ranges. Soils are generally shallow to moderately shallow, with ironstone gravel on the surface and overlying a hard pan. Not a Wetland. (BVG1M: 21b). |

| Fire management guidelines | SEASON: Various. INTENSITY: Moderate. INTERVAL: Typically every 6 - 12 years, with longer intervals required during periods of drought. INTERVAL_MIN: 6. INTERVAL_MAX: 12. STRATEGY: This vegetation is flammable and large proportions can burn in a single fire. Implement relatively small scale, patchy burns. Do not burn, or only burn small areas, during drought. ISSUES: The flora of this ecosystem regenerates well after fire, but often with slow growth rates. Melaleuca tamariscina shrubs resprout from the base of stems after fire but a proportion can be killed by intense fires. The post-fire coppice shoots of Melaleuca tamariscina shrubs may take 6 to 9 years to return to mature heights, depending on rainfall. Some shrubs that are present, e.g. Acacia tenuissima and Leptosema oxylobioides are killed by the fire and regenerate only by seedlings. Fire promotes the regeneration of some shrubs and herbs, however some fire-killed shrubs require several years post fire for most seedlings to mature (e.g. about 5 years for Acacia tenuissima). Ensure fire intervals allow shrubs to mature. |
| Comments | 11.5.10: Subject to frequent fires in some locations. |
