Regional ecosystem details for 3.3.40
| Regional ecosystem | 3.3.40 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This regional ecosystem is now mapped as 3.3.38. |
| Short description | Terminalia spp. deciduous vine thicket in depressions in Lakefield area |
| Structure code | Low Closed Forest |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.38. Low closed forest commonly containing Terminalia oblongata subsp. volucris, Melaleuca citrolens (scrub teatree), Cochlospermum gillivraei (kapok) and Croton arnhemicus. The shrub layer is sparse to mid-dense. A variant consisting of low open woodland of Terminalia spp. is found on heavy clay floodplains. Occurs in depressions in Lakefield area. Not a Wetland. (BVG1M: 7b). Vegetation communities in this regional ecosystem include: 3.3.40a: [RE not in use]²: This vegetation community is now mapped as 3.3.38d. The uneven canopy (4-8m tall) is dominated by a variety of species with Terminalia oblongata subsp. volucris, Melaleuca citrolens (scrub teatree), Cochlospermum gillivraei (kapok) and Croton arnhemicus the most frequent species. Occasional Eucalyptus acroleuca (Lakefield coolabah) trees are present as emergents (8-10m tall). The shrub layer is sparse to mid-dense, and 1-5m tall. There is an abundance of the scandent shrubs Capparis sepiaria, Stigmaphyllon timoriense and Ziziphus oenopolia present in the canopy and shrub layers. The ground layer is very sparse, with an accumulation of leaf litter on the ground. Occurs in depressions in Lakefield area. Not a Wetland. (BVG1M: 7b). 3.3.40b: [RE not in use]²: This vegetation community is no longer mapped. Terminalia aridicola subsp. chillagoensis (arid peach) and T. platyphylla dominate the biomass and form a very sparse canopy. sub-canopy trees are usually absent, but Piliostigma malabaricum is present in some areas. The shrub layer is very sparse to sparse with Grewia savannicola and Antidesma ghaesembilla occurring at highest densities. The mid-dense to dense ground layer is dominated by the herbs, Themeda arguens, Heteropogon contortus (black speargrass), Desmodium spp., Scleria spp., and Fimbristylis spp. Occurs on heavy clay on floodplains. Not a Wetland. (BVG1M: 32b). |
| Special values | 3.3.40: Potential habitat for NCA listed species: Ehretia microphylla. 3.3.40a: Floristic affinities with deciduous vine thickets of central Cape York Peninsula. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No deliberate fire management required within this unit. Undertake fuel reduction burns in surrounding vegetation utilising multiple small fires throughout the appropriate season to manage biodiversity values and to limit the extent and reduce risks of wildfire. ISSUES: Fire sensitive vegetation type. |
| Comments | 3.3.40: Lakefield area. 3.3.40a: Lakefield area. 3.3.40b: Vicinity of Laura-Lakefield. More intensive cattle grazing probable in the future. Thickening up of some patches has occurred, probably due to a decreased fire frequency. Some areas in the Einasleigh Uplands are heavily infested with weeds. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
