Hydroelectric plants are being planned or already built in Northern Finland. The complete terracing and regulation of watercourses necessary for the power plants will mean great changes in floating conditions and hence for forestry, for which floating is the principal means of transport. Consequently, the Cabinet appointed a committee in 1958 to ascertain the economic, technical and legislative questions connected with timber transport in the area.

The committee has found that about half of the country’s forest area and two thirds of its water power resources are situated in Northern Finland. A prerequisite for the wise utilization of the forest in Northern Finland is an increase in fellings. This can only be put into effect by improving the means of transport, especially the floating channels. The financing required by the organization of floating connected with the building of the hydroelectric power plants amounts to about 10,000 million marks over a period of 20 years.

The committee has suggested that an advisory committee on floating should be established. Its most important task would be to try to produce a general programme for the organization of floating under the changed conditions, and that the State should participate in the expenditure caused by the organization as regards the capital investment needed for changing over to bundle floating.

Silva Fennica Issue 69 includes presentations held in 1948-1950 in the fourth professional development courses, arranged for foresters working in the Forest Service. The presentations focus on practical issues in forest management and administration, especially in regional level. The education was arranged by Forest Service.

Floating channels of Northern Finland have been unable to fulfill all the needs of wood transportation of the area. This presentation presents diferent ways to improve the efficiency of floating by improving working methods and the channels, and thus decreasing costs of wood transportation.

The presentations focus on practical issues in forest management and administration, especially in regional level. The education was arranged by Forest Service.

This presentation discusses opportunities to increase the use of working machines, such as tractors, in construction of roads and floating channels, which have been little used in Finland. The presentation summarizes the machines available and their use based on experiences in Sweden.

Abstract | View details | Full text in PDF | Author Info

About 17.5% of forest lands of Finland is situated around the river and lake system of Lake Saimaa. Furthermore, the growth of the forests  of the area correspond about 25% of the total growth of forests in Finland. The watersystem is one of the most important portages of roundwood in the country. It consists 11,000 km of floating channels, 2,000 km of which suit for floating in bundles. Annually 30-35 million cu ft of saw logs, 7 million cu ft of veneer timber and 2,5-3 million cu ft of pulp wood is floated in the area.

Even if the water system at present still suits well for floating, there are many opportunities for development, which would improve its competitiveness against other modes of transport. Several different sites where building of floating channels or improving the floatways are needed are described in the article.

Abstract | View details | Full text in PDF | Author Info

 The numerous waterways have promoted the development of forest industry in Finland by offering an easy way to transport timber almost in the whole country. Floating associations arrange the floating for its members. This study, accomplished in the Forest Research Institute, compiles the statistics of the different associations in 1922­‒1927.  The volume of timber transported by the floating associations increased by 40% during the 6-year period, reaching 10.5 million m3 in 1927. The increase has been supported by the number of collectively used floating channels. The number of the floating associations increase from 17 to 26 and the length of the floating channels used by them to 8,300 km in 1922‒1927. About 70‒80% of the transported timber was logs and the 20‒30% small timber. Floated timber comprised 70-80% of the all roundwood used in the forest industry in Finland at the time. Majority of the logs were softwood.
