Regional ecosystem details for 9.12.20

Regional ecosystem 9.12.20
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 6, (3), (2), (7.4)
Estimated extent1 Pre-clearing 17000 ha; Remnant 2021 17000 ha
Short description Eucalyptus pachycalyx +/- E. cloeziana +/- Corymbia leichhardtii woodland on steep igneous hills
Structure code Woodland
Description Woodland to low woodland of Eucalyptus pachycalyx (pumpkin gum) +/- E. cloeziana (Gympie messmate) +/- Corymbia leichhardtii (yellowjacket) +/- Callitris intratropica (cypress pine) +/- E. portuensis (white mahogany) +/- E. cullenii (Cullen's ironbark) or E. atrata. The mid-dense shrub layer includes juvenile canopy species, Grevillea glauca (bushman's clothes peg), Persoonia falcata and Xanthorrhoea johnsonii (grass-tree). The medium to dense grassy ground layer is mostly dominated by Themeda triandra (kangaroo grass). Occurs on steep rugged hills on igneous hills. Not a Wetland. (BVG1M: 13a).
Protected areas Evelyn Creek CP, Baldy Mountain FR
Special values 9.12.20: This regional ecosystem is habitat for a number of vulnerable species including Corymbia rhodops, Grevillea glossadenia and Acacia purpureopetala.
Fire management guidelines SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. Avoid burning August-October when south-easterly winds are typically strongest. INTENSITY: Low, with occasional moderate or high. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. ISSUES: These ecosystems contain shrubs that germinate after fire. Seedlings typically take a number of years to mature. Avoid repeated fires at short intervals and high intensity burns of broad areas. Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. Shrub species diversity will decline if areas are left long unburnt. Callitris intratropica are fire sensitive. Protect from fires until plants old enough to replace seed pool.
Comments 9.12.20: A naturally restricted regional ecosystem. Occurs close to the Wet Tropics bioregion boundary in the central east of the bioregion.
