The forest "Monte río los Valdos"
covers 2455 ha of the natural park Saja-Besaya.
It's mainly composed of beech in wetland and shady areas
while oaks (Quercus robur and petrea) are growing in sunny
places.
An irregular undergrowth is allowed when beech' protagonism
is lower.
The forest management is conservative with a low cutting
activity. The aim is to protect the diversity and landscape
but also the genetic and cultural interest of the site.

Eucalyptus is one of the world´s most
widely used trees by forest industry. Among the more than
500 different species of Eucalyptus, white eucalyptus (E.
Globulus) was introduced in Galicia in the middle of the
XIXth century. It was rapidly planted all over the north
coast side of Spain. Origninally introduced for botanical
and ornamental purposes, it soon proved to be well adapted
for local forest conditions and wood production. Its sensitivity
to cold and frost limited its extension to coastal and low-lying
areas. Nevertheless other eucalyptus species, adapted to
these climatic conditions, had been tested and introduced
on a smaller scale.
The usual production systems involve tree planting in the
first rotation and shoot or sprout selection in the next
two rotations. The rotation length is between 12 and 15
years and intensive silviculture is applied during that
time. The average yield is around 15-20 m3/ha, although
it is not unusal to find 30m3/ha or greater for better quality
sites. Current tree breeding and technical improvement programs,
may result in improved practices. Because of exceptional
high productivity the eucalyptus forests have become an
important source of income for rural domestic economies
in the area. The great majority of wood production is used
by pulp industry, although present development and improvements
in the eucalyptus wood technology may open the door to future
uses such as sawn timber.

The Atlantic beech forests are the more extensive
and better conserved natural forest type in the north of
Spain. However, this extensive presence is quite recent,
due to expansion all through Europe following the last glaciation.
This type of forests is the result of intensive interaction
with the human intervention. Those idyllic forests, characterised
by straight trunks without branches, clean appearance and
a ground cover of fallen leaves that form a carpet are the
result of a type of forest management that has been carried
out for centuries. Those forests are generally with a regular
structure and most of the trees belong to the same age class.
Nevertheless, this is not the reality of most of the beech
forest of the west pyrenees regions. Most forests are located
in mountain areas with difficult access. Hence, the forests
have not been actviely managed for many decades, so now
their structure is semirregular with mixed ages and species.
Until the sixties, the forests were managed to obtain firewood
and this is why many trees orignate from sprouts. Nowadays,
it has got several economical final uses such as woodpulp,
furnitures, parquet.
Live stock is often present in these mountain forests and
this has resulted in stability problems.The future the management
of this forests should be adapted to maintain their important
protection function. Any harvesting should be carried out
using cable cranes or similar technologies to protect the
environment and the soils. These interventions should be
oriented to obtain high quality and large dimension stems,
minimizing the intermediate clearing operations.
