VDYP7 Attribute Adjustment

Q
What input variables does VDYP7 Attribute Adjustment need in order to initiate a growth projection?
 
A

The 11 variables are:

  • Dominant height
  • Dominant age
  • Trees/ha (7.5 cm +)
  • Basal area (7.5 cm +)
  • Lorey height (7.5 cm +)
  • Whole stem volume (7.5 cm +)
  • Whole stem volume (12.5 cm+)
  • Close utilization volume (12.5 cm+)
  • Close utilization volume less decay(12.5 cm+)
  • Close utilization volume less decay and waste(12.5 cm+)
  • Basal Area (12.5 cm +)

VDYP7 Attribute Adjustment needs the first four variables to predict the last seven. Once the first four variables are predicted, VDYP7 Attribute Adjustment uses the same equations to predict the last seven variables.
