Part of the tree affected Severity of attack Type of damage
S Stem Main Class Value Sub- Class % damage of part affected Severity scale (from Rohrmoser) N No damage
B Branch M Tree missing
F Flower/Fruit X Wrong species
L Leaves Severe 1 > 90 % Affected plant parts dominate the appearance of the plant I Insect damage
R Roots 2 70-90% D Nutrient deficiency
W Whole tree 3 60-70% P Animal (physical)
B Bark Medium 4 50-60% H Human (cutting)

5 40-50% C Cold/frost
6 30-40% Healthy plant parts dominates the appearance of the plant F Fire
Slight 7 20-30% S Water stress (drought)
8 10-20% Symptoms scattered L Water logging
9 < 10% W Wind

U Unknown
O Others

If there is no damage (N or blank) i.e. tree is healthy, or if the tree is missing (M) or not the correct species (X), the first two columns (part of the tree affected and severity of attach) are left blank.
