| Structure code | Woodland |

| Fire management guidelines | SEASON: Mid-dry season. INTENSITY: Low to moderate. INTERVAL: Occasional fires, typically every 5 - 10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Use occasional burning to promote herbs and shrubs and reduce excessive fuel build up that can cause high intensity fires. ISSUES: The coastal north Queensland populations of Grevillea pteridifolia are fire-killed obligate seeders with fire promoted germination. Many herbs are promoted by fire, such as ground orchids. Conversely, terrestrial orchids can be killed by fires that are intense enough to scorch them in the canopy and therefore they provide a useful indicator of past fire intensities. Maintain a diverse ground and shrub layer. Where Grevillea pteridifolia or other fire-killed shrubs are present, wait until subsequent post-fire seedlings have matured before burning again. |
