Εffect of summer drought in the natural regeneration of valonia oak

This paper presents an initial attempt to investigate the effect of drought in the mortality of valonia oak (Quercus ithaburensis subsp. macrolepis) seedlings and young saplings in a silvopastoral system in western Greece. The experiment was conducted in fenced experimental plots where the number of seedlings and young samplings was measured in May and October before and after the dry summer period for the years 2015, 2016, 2017 and 2018. The results show that the number of seedlings and young saplings decreased on average by 24.7% in October attributed mainly to the effect of summer drought.
