    After the severe ice storm in 2014, numerous damaged trees were not removed from forests. Due to the lack of general knowledge about the processes occurring in damaged trees, a study involving 14 European beeches was conducted in the Arboretum Volčji Potok. Trees were categorized by crown injury; injury class K % undamaged, A % damaged less than 50 %, B % damaged between 50 and 75 %, and C % damaged more than 75 %. During the 2014 growing season, micro-cores were collected every fortnight using a Trephor tool. Changes in crowns were also observed and noted. Transverse sections of micro-cores were prepared and observed using light microscopy and an image analysis system. Xylem growth rings were 20 to 95 % narrower in damaged beech trees compared to the undamaged trees. Damaged trees also produced narrower phloem rings. The biggest differences in cambial activity in beech appeared between Class A and Class B.
