| Special values | 7.11.18: Potential habitat for NCA listed species: Peristylus banfieldii. |
| Fire management guidelines | SEASON: Begin burning after the wet season (April-May), but avoid hot, dry season unless a high intensity fire is required to manage thickening, then undertake storm burn. INTENSITY: Low, with occasional moderate or high intensity to manage thickening and/or stimulate germination. INTERVAL: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Mosaic burn 25-60%. Begin burning early in the fire season, with progressive patch fires burnt through the year. Stop burning when the network of fires and other breaks is sufficient to impede fire spread later in the year. Storm-burning may be used to add further diversity to fire mosaic, promote perennial grasses and arrest woody thickening. ISSUES: In the absence of fire an abundance of rainforest pioneers (e.g., Melastoma spp., Chionanthus ramiflora, Mallotus philippensis, Alyxia spicata and Glochidion spp.) and bracken fern can establish. This development can be rapid (within about 15 years) after which system change is difficult to reverse. Thickening with rainforest species can be detrimental to habitat trees and endangered species. Where fire is more common the understorey is usually dominated by tall grasses (e.g., Themeda triandra and Eriachne pallescens), herbaceous plants, lilies and sedges (e.g., Tricoryne anceps, Gonocarpus acanthocarpus, Lomandra longifolia, Dianella caerulea). |
| Comments | 7.11.18: Threatened by rainforest invasion and residential development. Distinguished from 7.11.43 and 7.11.51 by the dominance of Corymbia intermedia instead of C. clarksoniana (wetter zones than 7.11.143 and 7.11.51). Distinguished from 7.11.19 by its occurrence on headlands and near-coastal foothills as opposed to sub-coastal zones. Distinguished from 7.11.34 by its medium to tall stature (7.11.34 consists of mosaics of grasslands and shrublands with low wind-sheared eucalypt stands.). Scattered along coastal ranges north from about Cardwell. The structure and maintenance of this regional ecosystem are dependent upon appropriate fire management regimes. 7.11.18b: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. 7.11.18d: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. 7.11.18f: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. |
