i
Number of living and dead trees and shrubs (standing and lying) ≥12 cm diameter at breast heigth (dbh) with damage. Only the two most important forms of damage to a tree are recorded. Since a tree may be damaged in different ways, it may contribute more than once to the total number of stems with the two most important forms of damage.

i
Cause of damage to trees and shrubs ≥12 cm in diameter at breast height (dbh) – in ten classes. Eight of these classes focus exclusively on standing living trees and shrubs with dbh ≥12 cm, while one class applies to lying living trees and shrubs with dbh ≥12 cm, and one to dead trees and shrubs with dbh ≥12 cm. Reference: Field Survey (MID 1029: Baumschadenursache, MID 1018: Baumzustand)

i
Type of damage to trees and shrubs ≥12 cm in diameter at breast height (dbh) – in thirteen classes. Eleven of these classes focus exclusively on standing living trees and shrubs with dbh ≥12 cm, while one class applies to lying living trees and shrubs with dbh ≥12 cm , and one to dead trees and shrubs with dbh ≥12 cm. Reference: Field Survey (MID 1027: Baumschadenart, MID 1018: Baumzustand)
