| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins; this requires further research. |
| Comments | 12.5.13: Characteristic localities for the RE are Yarraman-Tarong-Boat Mountain. Cleared for agriculture and hoop pine plantation. Remnants can be degraded by weed infestation in conjunction with wildfire damage on margins. 12.5.13a: Characteristic localities for the RE are Yarraman-Tarong-Boat Mountain. Cleared for agriculture and hoop pine plantation. Remnants can be degraded by weed infestation in conjunction with wildfire damage on margins. 12.5.13b: Deepwater Creek catchment. Mostly cleared for horticultural production. Only persists as small remnants that can be degraded by weed infestation in conjunction with wildfire damage. 12.5.13c: Mostly restricted to western margins of central part of bioregion in the vicinity of Barambah Creek extending westward into the Brigalow Belt. Remnants require intensive management because of invasion by weeds and fire damage on margins. |
