Form 5a - ICP Forests

(39) Tree number with initial F for Foliage, R for Ring and D for Disk
sampling
(Chapter 4, 5, 10)
As in some samplings (foliar, increment, ozone injury) trees outside the normal plot (or
sub plot) have to be used, special numbers have to be applied. The number of these trees
will start with a letter (F=Foliage), R=Ring analysis by increment borings, D=Disc
analysis) followed with a sequence number (e.g. F001). The numbers are to be reported.
Ozone injury assessments are carried out on trees with foliar assessments and thus are
numbered like these (e.g. F001). Only if additional trees are sampled specifically for
ozone injury new codes are given (e.g. O001).

(41) Mass of 100 leaves or of 1000 needles
(Chapter 4, 11)
The mass is determined of 100 leaves or 1000 needles (oven-dry) in grams
(42) Diameter at breast height (DBH)
(Chapter 5)
The diameter at breast height (1.30 m) over bark in 0.1 centimetres.
When a diameter tape is used a single value will be needed. When calipers are used the
maximum and the minimum diameter (over bark) shall be determined and reported
(diameter 1 and diameter 2).
(43) Bark
(Chapter 5)
The thickness of the bark at 1.30 m, expressed in centimetres with one decimal.
(44) Height rounded off to the nearest 0.1 meters
(Chapter 5)
The height of the tree expressed in metres to the nearest 0.1 metres.
