methods of assessment the damage to stands
silver fir - Opis:
- Paper presents two variants of the method of assessment the damage to the silver fir stands that were determined on the basis of the crown development. The first one is based on the tree's defoliation, the other – on the tree's damage index W that includes defoliation (feature A), condition of the tree−top (feature B) and tree's vitality (feature C). Mean defoliation or index W is used to determine one of the four classes of the stand damage. The accuracy of both variants was worked out and minimum number of sample trees required within assumed standard errors of assessed features was determined.
