  • Oak mortality should be seen as a combination of long- and short-term stresses, wherefore an identification of one specific factor causing the actual death of the oaks in this study is impossible.

     
  • In order to fully understand the causes of oak mortality there is an equal need of studying present as well as past factors influencing the oaks’ vigour, since the history of a tree is essential for its present chances of survival.

     
  • Although this study presented a rather modest influence of the impact of environmental variables on oak mortality, site specific properties should not be considered unessential when analysing the causes of oak mortality.
