L.HISTORY

This species appears in Galician ecosystems when it reaches the ecological balance. Due to this, it was very common in Galicia.

Oak

wood was widely used in ship building in the 16th,17th

and mainly in the 18th

centuries. Later it was used to make sleepers for the railways. Due to this, the number of specimens decreased and oaks disappeared in many places.

Acorns were a great source of carbohydrates before chestnuts were introduced by the Romans.

Oak wood was very appreciated to make beams and furniture. Nowadays it is sought to make barrels to mature wines and whiskies.

L.INTERESTING FACTBuilding

a medium-

sized

vessel

requiered 4000 m3

of

wood, 3000 m3

of

which

were

oak wood.

This

amount

is equivalent

to

1500 big

oak

trees, around

50 hectares

of

oak

forest

more than

150 years old.

According

to

the

system used

to

select

the

trees

–they

had

to

have certain

features-

this

number

could

be ten times higher.

HISTORY

It

comes from

the

Eastern Mediterranean

area, from

where

it spreaded

to

be grown

due

to

its

many

uses. It

became

acclimatized

to

Galicia very

easily

and

was

one

of

the

most important

trees

in our

region

due

to

its

good

wood

and

also

food

too.Nowadays

the

number

of

specimens

has diminished

due

to

it

not

being

cultivated

any

more, the

felling

and

several

fungal diseases.

In our region chestnuts are eaten in Autumm, when they are ripe, and mainly around two catholic holidays: the Day of the Dead (October 31st ) and All Saint’s Day (November 1st ). The rest of the year they are eaten dry.

History

This tree was introduced from Eastern Asia in the 18th century and it is grown for ornamental purposes all over Spain.

It became acclimatized to Galicia so well that now it is one of the most important species. It can be found in many parks and gardens in all its varieties, their main difference being their flowers.

exhibitions are held in many villages and

towns of Galicia all over the year.

ActivityWe suggest working with these three trees in all the countries involved.

The students could find out if there are specimens of every specie in their country.

If so, they could study and compare their botanical characteristics, history and uses against the Spanish specimens. With the results they could complete a project like the one we show on the right or other similar ones.

If not, they could find out the reason why they don’t grow in their countries (incompatible climate, topography, etc).
