Preface.
In 1922—1923 a survey of the forests of the whole country was
made in Finland, on the basis of which a thorough knowledge of the
forest resources of the country and their condition was obtained.
The results of the survey provided a broad and sure foundation for
the future planning of Finland’s forestry. However, in the course of
time the forest resources may change very greatly. The forests grow
and are felled, they age and new ones take their place, methods of
forest management alter and efforts are made to improve their
condition. For all these reasons even an exact conception of the forest
resources of a country and their condition obtained at a given time
will change. Before long, therefore, it began to be realised in Finland
that a fresh survey was necessary.
The second national survey of the Finnish forests was carried out
in 1936—1938, i. e. about 15 years after the first survey. The field
work was completed by the end of 1938 and a year later, or at the
end of 1939, the calculation of the main results of the survey was
concluded. It was intended to present them at a joint meeting of the
Society of Forestry of Finland and the Geographical Society of
Finland to be held in Helsinki on December 15th, 1939, but the state of
war created by Russia’s attack on Finland prevented the holding of
the meeting and the proposed reading of the paper. As the work of
calculating the results of the survey was almost entirely interrupted
by the war and some considerable time would elapse before the
detailed results could be prepared, it was thought advisable to print the
contents of the proposed paper. Even this has been delayed by other
duties connected with the present circumstances.
The object of the present paper, therefore, is to give a brief
description of some of the main results of the national forest survey
which may, perhaps, be of more general interest. At the same time
a condensed comparison has been made between the results of the
first and second national forest surveys carried out in 1922—1923
and 1936—1938, as such a comparison illustrates in broad lines the
