Decline of pedunculate oak (Quercus robur L.) was observed synchronously in a number of sites (Helama et al., 2009, 2014; Sohar et al., 2014a), this event thus contributing to the wider episode of dying back in this region, southern Finland, where the remaining stands represent the northern distributional limit of Quercus worldwide (Axelrod, 1983; Ducousso & Bordacs, 2004).

In Lithuania however, situated beyond the continuous range of the beech, pedunculate oak becomes the essential tree in habitats of G.

Under such conditions, sessile oak grows either in pure or mixed stands along with other broadleaved tree species such as European beech (Fagus sylvatica L.), hornbeam (Carpinus betulus L.), sycamore (Acer pseudoplatanus L.), common ash (Fraxinus excelsior L.), linden (Tilia sp.) or other Quercus species such as pedunculate oak (Quercus robur L.), Hungarian oak (Quercus frainetto L.) or Turkey oak (Quercus cerris L.) (Haralamb, 1967; Stanescu et al., 1997; Sofletea and Curtu, 2007).
