the forest and wild life??
READING PASSAGE
Forests are
one of the main elements of our natural heritage. The decline of Europe’s
forests over the last decade and a half has led to an increasing awareness and
understanding of the serious imbalances which threaten them. European countries
are becoming increasingly concerned by major threats to European forest,
threats which know no frontiers other than those of geography or climate: air
pollution, soil deterioration, the increasing number of forest fires and
sometimes even the mismanagement of our woodland and forest heritage. There has
been a growing awareness of the need for countries to get together to
co-ordinate their policies. In December 1990, Strasbourg hosted the first
Ministerial Conference on the protection of Europe’s forest. The conference
brought together 31 countries from both Western and Eastern Europe. The topics
discussed include the co-ordinated study of the destruction of forest
ecosystem. The preparatory work for the conference had been undertaken at two
meetings of experts. Their initial task was to decide which of the many forest problems
of concern to Europe involved the largest number of countries and might be the
subject to joint action. Those confined to particular geographical areas, such
as countries bordering the Mediterranean or the Nordic countries therefore had
to be discarded. However, this does not mean that in future they will be
ignored.
As a whole,
European countries see forests as performing a triple function: biological,
economic and recreational. The first is to act as a ‘green lung’ for our
planet; by means of photosynthesis, forest produce oxygen through the
transformation of solar energy, thus fulfilling what for humans is the
essential role of an immense, non-polluting power plant. At the same time,
forests provide raw materials for human activities through their constantly
renewed production of wood. Finally, they offer those condemned to spend five
days a week in an urban environment an unrivalled area of freedom to unwind and
take part in a range of leisure activities, such as hunting, riding and hiking.
The economic importance of forests has been understood since the dawn of man—wood
was the first fuel. The other aspects have been recognised only for a few
centuries but they are becoming more and more important. Hence, there is a real
concern throughout Europe about the damage to the forest environment which
threatens these three basic roles.
The myth of
the ’natural’ forest has survived, yet there are effectively no remaining
‘primary’ forests in Europe. All European forests are artificial, having been
adapted and exploited by man for thousands of years. This means that a forest
policy is vital, that it must transcend national frontiers and generations of
people, and that is must allow for the inevitable changes that take place in
the forests, in needs, and hence in policy. The Strasbourg conference was one
of the first events on such a scale to reach this conclusion. A general
declaration was made that ‘a central place in any ecologically coherent forest
policy must be given to continuity over time and to the possible effects of
unforeseen events, to ensure that the full potential of these forests is
maintained.’
That
general declaration was accompanied by six detailed resolutions to assist
national policy-making. The first proposes the extension and systematisation of
surveillance sites to monitor forest declined. Forest declined is still poorly
understood but leads to the loss of a high proportion of a tree’s needles or
leaves. The entire continent and the majority of species are now affected:
between 30% and 50% of the tree population. The condition appears to result
from the cumulative effect of a number of factors, with atmospheric pollutants
the principal culprits. Compounds of nitrogen and sulphur dioxide should be
particularly closely watched. However, their effects are probably accentuated by
climate factors, such as drought and hard winters, or soil imbalances such as
soil acidification, which damages the roots. The second resolution concentrates
on the need to preserve the genetic diversity of European forests. The aim is
to reserve the decline in number of tree species or at least to preserve the
‘genetic material’ of all of them. Although forest fires do not affect all of
Europe to the same extent, the amount of damage caused the experts to propose
as the third resolution that the Strasbourg conference consider the
establishment of a European databank on the subject. All information used in
the development of national preventive policies would become generally
available. The subject of the fourth resolution discussed by the ministers was
mountain forests. In Europe, it is undoubtedly the mountain ecosystem which has
changed most rapidly and is most at risk. A thinly scattered permanent
population and development of leisure activities, particularly skiing, have
resulted in significant long-term changes to the local ecosystems. Proposed
developments include a preferential research program on mountain forests. The
fifth resolution re-launched the European research network on the physiology of
tress, called Eurosilva. Eurosilva should support joint European research on
tree disease and their physiological and biochemical aspects. Each country
concerned could increase the number of scholarships and other financial support
for doctoral theses and research projects in this area. Finally, the conference
established the framework for a European research network on forest ecosystems.
This would also involve harmonising activities in individual countries as well
as identifying a number of priority research topics relating to the protection
of forests. The Strasbourg conference’s main concern was to provide for the
future. This was the initial motivation, one now shared by all 31 participants
representing 31 European countries. Their final text commits them to on-going
discussion between government representatives with responsibility for forests.
