Other tree species: in July of the mast year - lime (2 %), locust (1 %), spruce (0.5 %); in August of the mast year - maple (2.3 %), pedunculate oak

The two main European oak species used for barrels are Quercus robur, also known as pedunculate oak
, and Quercus petraea, also known as sessile oak.
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).

Comparison of morphological and genetic traits of pedunculate oak
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).
Comparative study of genetic variation and differentiation of two pedunculate oak
(Quercus robur) stands using microsatellite and allozyme loci.
A few other native broadleaved species, such as ash, silver birch and pedunculate oak
, will also be planted for diversity.
The pulsation coefficients of diameter growth of pedunculate oak
(Quercus robur L.) are: [[omega].sub.pd] = 0.0729927, of crown expansion uD = 0.1824817, and of height growth [[omega].sub.ph = 0.1459854.
The Welsh logo differs slightly from the English party's emblem, the foliage appears thicker and taller, representative of the differences between the sessile oak and the pedunculate oak
, which grows in eastern parts of Britain.
