Tree condition assessment on hail-damaged trees in Carinthia (South Ausria). In July 1993 a very strong hail storm caused severe damage on Norway spruce and Scots pine in the centre of the hail damaged area. Radial increment decreased to a level of about 10% of the previous years. The average rate of defoliation of Norway spruce in teh centre was about 60%, that of Scots pine about 70-80%. In 1995 more than 60% of the trees in the centre were dead, the others in a very bad condition, sometimes because of the succeeding attacks of bark beetles.
