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.

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. Alarming picture of Norway spruce stands in Polish Carpathians and Sudety Mountains appeared for the damaged stands prevail while there is no undamaged stands.

(pinus sylvestris l.)
Opis:: Basing on tree crown characteristics different variants of the damage assessment method for pine stands were distinguished. The verification of the variants was carried out in 35 stands of the Olkusz Forest District that in the past had been under strong impact of industrial emissions. Prevalence of slightly dam− aged stands was observed in the studied area. Taking into consideration a high share of non−damaged stands it was stated that the actual health status of forests in the Olkusz Forest District's is satisfactory.
