Assessing the Risk of Snow and Wind Damage from Tree Physical Characteristics
The study was carried out in a Scots pine ( Pinus sylvestris L.) stand in northern Sweden. The stand was heavily damaged by wind and snow in the 1989–1991 period. Height, clear bole height, and d.b.h. were measured on 72 sample trees. D.b.h. was also measured on all trees within 3 m of each sample t...
