Risk Definitions
  • ‘Biophysical Hazard’ is the combination of the topographic, soils and stand hazard components. It represents the intrinsic windloading and wind stability of trees on the site prior to treatment.
  • ‘Treatment Risk’ is the way in which a particular treatment increases or decreases the windloading or wind resistance of trees.
  • ‘Windthrow Risk’ is the likelihood of damage from endemic winds. It is the combination of Biophysical Hazard and Treatment Risk.
  • ‘Windthrow Impact’ refers to the potential harm windthrow could cause if it occurs. Impact is negative if wind damage results in management objectives not being met. If some level of damage is acceptable, this should be indicated in the original silviculture prescription.
