Article V - DAMAGE TO ORCHARDS
Section 1752 - FORMULAS FOR CALCULATION OF BARK DAMAGE
Current through Register Vol. 47, No. 17, September 10, 2024
A. Short term bark damage (0-33%/limb or trunk) = no loss
B. Long term bark damage
$ Loss = (# of trees) (Bu/Tree) (33%) (ORV Equivalent) (2.0) (87%) Where,
|
ORV Equivalent = |
(ORV/Bu) - (Harvest + Haul Cost/Bu) |
|
2.0 Factor = |
Recovery Loss Adjustment for 4-year recovery period. |
|
87% = |
Present value percentage factor from column 3 of Table B of #1754. |
|
$ Loss = |
(# of Trees) (Bu/Tree) (65%) (ORV Equivalent) (3.5) (80%) |
|
Where, |
|
|
ORV Equivalent = |
(Orchard Run $/Bu) - (Harvest + Haul Cost/Bu) |
|
3.5 Factor = |
Recovery Loss Adjustment for 6- year recovery period. |
|
80% = |
Present value percentage factor from column3 of Table B of #1754. |
C. Permanent Bark Damage (60+%/Limb or trunk) = 100% Loss
Trees which have a limb and/or truck-limb damage in excess of 60%.
|
$ Loss/Tree= |
(Bu/Tree) (# 100%-loss limbs/Total # Limbs) (ORV Equivalent) (Years) (P.V.1) + (Bu/Tree) (# 33%-loss limbs/Total #limbs) (33%) (ORV Equivalent) (2.0) (87%) + (Bu/Tree) (# 65%-loss limbs/total # limbs) (65%) (ORV Equivalent) (3.5) (80%) |
|
Where |
|
|
ORV Equivalent = |
(ORV/Bu) - (Harvest + Haul Cost/Bu) |
|
Years = |
Remaining Commercial Life |
|
P.V.1 = |
Present value percentage factor from Column 3 of Table B of #1754 based on # of years of remaining commercial life. |
|
2.0 and 3.5 factors = |
recovery loss adjustment for 4 and 6 year recovery periods respectively. |
|
87% and 80% = |
present value percentage factors from column 3 of Table B of #1754 for 4 and 6 year recovery periods. |
|
(Recovery period for 33% damaged tree is deemed to be 4 years and for 65% damaged tree it is deemed to be 6 years.) |
|
|
Total Block $ Loss = |
sum of losses calculated for individual trees. |
|
Production $ loss = |
(# of trees) (Bu/tree) (ORV equivalent) (Years) (P.V.) |
|
Replacement $ Cost = |
(# of trees) (Cost of removal/tree + replacement cost/tree + replant cost/tree - operational cost savings) |
|
Total $ loss = |
Production $ loss + replacement $ cost |
|
Where, |
|
|
ORV Equivalent = |
(ORV/Bu) - (Harvest + Haul Cost/Bu) |
|
Years = |
# years of remaining commercial life, but not greater than 10 years for apple, 8 years for peach/apricot, 15 years for sweet cherry, 10 years for sour cherry. |
|
P.V. = |
Present value percentage factor from column 3 of Table B of #1754 based on # years of remaining commercial life. |
