Structure code Woodland
Description Angophora leiocarpa, Eucalyptus interstans +/- Corymbia intermedia, E. tereticornis C. tessellaris, C. clarksoniana, C. gummifera, E. siderophloia, C. citriodora subsp. variegata woodland to open forest.

Special values 12.9-10.28: 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 12.9-10.28: Previously mapped as 12.9-10.12a. Eucalyptus interstans is the diagnostic species of this regional ecosystem and it often occurs as a subdominant component. Occurs near Esk. Subject to increasing fragmentation and urbanisation.
