Beech, European
Fagus sylvatica L. Family:
Fagaceae
Other names:
English, Danish, French, Slavonian etc. beech, according to origin.
Distribution:
Europe, especially central Europe and Britain.
The tree:
Beech has been called the mother of the forest, since without it in mixed
broad-leaved forests, other hardwood umber trees would have greater difficulties
for survival. The rain drip from beech destroys many soil-exhausting weeds, its
shade prevents over-evaporation of moisture from the soil, and its heavy crop of
leaves provides humus to the soil.
In close forest, it can reach a height of 45m with a clear bole of 1 5m but
on average this is usually about 9m with a diameter averaging 1 .2m occasionally
more.
The timber:
Normally, there is no clear distinction by colour between sapwood and
heartwood, the wood being very pale brown when freshly cut, turning
reddish-brown on exposure, and deep reddish-brown under the influence of
steaming treatment commonly applied in parts of the Continent before shipment.
Some logs show an irregular, dark reddish-coloured kern or heart, caused it
is believed, by the effect of severe frosts, and occurring more frequently in
Continental beech. The wood is typically straight grained, with a fine, even
texture, but varying in density and hardness according to the locality of
growth. Thus beech from central Europe, norably that from Yugoslavia (Slavonian),
and that from Romania is milder and lighter n weight, about 672 kg/rn3, than
beech from Britain, Denmark and northern Europe, which weighs about 720 kg/rn3
when dried.
Drying:
Although it dries fairly rapidly and fairly well, beech is moderately
refractory, tending to warp, twist, check and split, and shrink considerably. It
therefore requires care both in air drying and kiln drying.
Strength:
Green beech has general strength properties roughly equal to those of oak,
but after drying, most values increase, and beech is stronger than oak in
bending strength, stiffness and shear by some 20 per cent, and considerably
stronger in resistance to impact loads.
Durability:
Perishable.
Working qualities:
Beech varies somewhat in its ease of working and machining according to
growth characteristics and dried condition. Thus. fairly tough material, or
badly dried stock may tend to bind on the saw, or burn when cross-cut, or, if
distorted due to drying, provide difficulties in planing. On the whole, however,
it works fairly readily, and is capable of a good smooth surface. Beech turns
well, takes glue readily, and takes stains and polish satisfactorily. It
produces excellent veneer.
Uses:
The uses for beech are innumerable, from furniture, both solid and laminated
from veneer, to domestic woodware, shoe heels. toys, bobbins, tool handles,
interior joinery, interior construction, and plywood, flooring, turnery.
The various types of beech tree used throughout Europe, mainly for decorative
purposes are considered to be sports from the purple variety, which in turn was
a natural sport from the common beech discovered in a German wood more than a
hundred years ago. A sport is a tree that deviates strikingly from the type of
its species, thus
F. sylvatica L. var. cuprea Loud, produces copper beech
F. sylvatica L. var. heterophylla Loud, produces fern-leaved beech
F. sylvatica L. var. pendula Loud. produces weeping beech
F. sylvatica L. var. purpurea Ait. produces purple beech
F. sylvatica L. var. purpurea pendule Rehd. produces weeping
purple beech.
Fagus orientalis Lipsky is a separate species found in Asia Minor, the
timber of which is known as Turkish beech, and which is similar in appearance
and properties to those of common beech.
