Regional ecosystem details for 9.12.14

Regional ecosystem 9.12.14
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 2, (2.9)
Estimated extent1 Pre-clearing 21000 ha; Remnant 2021 21000 ha
Short description Eucalyptus crebra and E. similis +/- Callitris intratropica low open woodland on hills on igneous rocks
Structure code Low Open Woodland
Description Low open woodland to woodland of Eucalyptus crebra (narrow-leaved ironbark) (sens. lat.) and E. similis +/- Callitris intratropica (cypress pine), +/- Corymbia erythrophloia (red bloodwood) +/- C. polycarpa (long-fruited bloodwood) +/- Terminalia aridicola (arid peach). The mid layer is absent to sparse and can contain juvenile canopy species, Acacia julifera (catkin wattle), Petalostigma spp. and Grevillea glauca (bushman's clothes peg). The grassy ground layer is dominated by a Schizachyrium spp. (firegrass) and Heteropogon contortus (black speargrass). Occurs on undulating low hills and rises with rocky outcrops. Not a Wetland. (BVG1M: 13c).
Supplementary description Perry et al. (1964): Leichhardt Unit 1
Protected areas Blackbraes NP
Special values 9.12.14: Potential habitat for NCA listed species: Cycas couttsiana.
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 9.12.14: The rocky outcrops commonly have Acacia julifera shrubland, E. similis and some deciduous low woodland species present. Occurs near the Chudleigh Plateau in the west of the bioregion.
