3.111.500 seeds for kilo.

USES

This red eucalyptus is renamed by his brilliant reddish wood, ranging between soft rose

to red blackish, depending on the age. It is very fragile and generally with crossed grain

that makes it very difficult the manual work. It was often used for applications of

resistance like girders, posts. More recently have been used for thin furniture due to his

BIOLOGY DEPARTMENT

MAN AND THE TREE

The Department of Biology collaborated with the

project Man and the tree working with pupils of 4

ESO during the school years 2008-09 and 2009-10, in

a work based on the most representative species of the

arboreal Galician flora, including autochthonous

species and other species introduced by the man that

became also abundant in Galicia.

The

distinctive

characteristics of its leaves, flowers, fruits, etc havebeen dealt, as the the traditional uses that men and

women have given to them.

Several files were writtenexplaining the characteristicsof every specie. Photos ofeach specie were alsoincluded in the files. Some of

them have been taken by thepupils and others have beendownloaded from the Net.

Oak is one of most emblematic specie in Galicia

Mimosa is one of most abundant species
