i
Stemwood volume of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark that were not removed from the forest as part of silvicultural planning, but because they had been damaged (e.g. by windthrow, avalanches, insects or rockfall). The variable is derived at the sample plot level from the harvested tally trees and the proportion of sanitary/salvage fellings (according to information provided by the foresters).
