| Regional ecosystem | 12.11.17 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 7, 10, 5, 11.18, 6, (8) |
| Estimated extent1 | Pre-clearing 11000 ha; Remnant 2021 5000 ha |
| Short description | Eucalyptus acmenoides or E. portuensis open forest on metamorphics +/- interbedded volcanics |
| Structure code | Open Forest |
| Description | Eucalyptus acmenoides or E. portuensis, Corymbia trachyphloia open forest to woodland +/- E. crebra, Angophora leiocarpa, E. exserta, C. intermedia, Lophostemon confertus (whipstick form). Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Not a Wetland. (BVG1M: 9h). |
| Supplementary description | Bean et al. (1998), H24 (in part), J12 (in part) |
| Protected areas | Grongah NP, Calliope CP, Mount Walsh NP, King CP, Bulburin NP |
| Special values | 12.11.17: Potential habitat for NCA listed species: Macrozamia parcifolia, Phebalium distans and Pomaderris clivicola. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. |
| Comments | 12.11.17: Comparable to RE 12.11.5 but less species rich and Eucalyptus acmenoides or E. portuensis is predominant. More widespread in northern part of bioregion. |
