Objectives and strategies:

Strategic Fire Management ZoneObjective: To protect private property along Morella Rd & the Manor HouseStrategies: Assess fuel loads prior to fire season each year by Visual Assessment method Maintain fuel at <15t/ha by manual clearing or prescribed burning Extinguish all wildfire Heritage Area Management ZoneObjective: To maintain natural & cultural assetsStrategies: Pile burns may be employed to remove weed material and stimulate regeneration if required in weed infested areas close to Morella Road Any fire within the lifetime of this plan is unlikely to have an adverse effect on biodiversity.
